DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, a gaming machine and a playing method thereof according to an embodiment of the invention will be described.

An embodiment of the invention will be described with reference to FIGS. 1 to 19. A gaming machine is structured to obtain a lottery right based on a bet and thus to perform a lottery while displaying the lottery right obtained. In other words, as shown in FIG. 1, a gaming machine 101 includes: a gaming machine main body 102 that executes a game; several terminal devices 103 each of which receives a special payout target and awards a payout; a display device 104 that displays image data relating to the game; and a controller 105 of FIG. 2. The controller 105 is configured to execute a program that operates as described in steps of (a1) to (a5).

Specifically, in a step of (a1), the controller awards to each terminal device 103 a base payout based on an execution result of a game and a game value bet. In a step of (a2), the controller determines whether to set each of the terminal devices as a possible target for a special payout, based on the respective bets in the terminal devices 103. In a step of (a3), when any one of the terminal devices 103a is set as the possible target (the terminal device set as the possible target is hereinafter referred to as participating terminal 103), the controller outputs the image data to the display device 104 so as to specify the terminal device 103 possible target as a possible target. In a step of (a4), the controller randomly selects a special payout target from a group of possible target one or more possible targets. In a step of (a5), the controller awards a special payout in the terminal device 103 selected as the special payout target.

Here, the “gaming machine 101” may be a one player-type or a multi participant-type. For example, the gaming machine 101 may include a gaming machine (roulette gaming device 1) that executes a roulette game and the like, on condition that many players take part in the game. Furthermore, the gaming machines such as slot machine in which one player plays a game may be associated with each other so that via data communication is possible, thereby constituting a multi participant-type gaming machine.

The “gaming machine main body 102” may execute a game by means of a mechanical operation, an electrical operation or a combination of mechanical and electrical operations, as long as the game is a multiplayer-type game. The game executed by means of a mechanical operation can be a game using a roulette unit 3 that rotates or moves an actual ball or wheel. The game executed by means of an electrical operation can be a game that virtually rotating or moving an image of a ball or wheel displayed on a display device such as liquid crystal display.

The “terminal device 103” may be a gaming-only terminal device (station 4) or an information processing device such as a personal computer used for multiple purposes, as long as it can receive a bet for a game and award a payout. The “image data” may be still image data or moving image data. Further, the image data may be the number of the terminal device 103, a name or face specifying a player, animals and plants, motif and the like. The “display device 104” may be provided in each of the terminal devices 103 or may be a single large screen display shared among all the terminal devices 103. For example, the display device 104 may include a liquid crystal display device, a CRT (Cathode-Ray Tube) device, a plasma display device and the like.

A method of specifying the participating terminal 103 possible target may be a method of outputting the image data of the number of the terminal device 103 and the like on the display device 104, or a method of switching an image of a special payout symbol indicator 62 in the display device 104 of the participating terminal 103 possible target from a still state to a moving state.

The “execution result of a game” is a state where a game could enter a “win” state as a result of executing a unit game. In this embodiment, the “execution result of a game” may be also referred to as a “game result.” For example, in a roulette game in which a ball is rolled on a wheel, an execution result is a mark on the wheel corresponding to a stop position of the ball. In a slot game, an execution result is a pattern of symbols stopped after rearrangement. Note that the “rearrangement” means arranging the symbols again after dismissing the arrangement of the symbols. The “arrangement” means a state in which the symbols are visible to an exterior player.

The “unit game” is a series of operations from a reception state of a bet (bet time) to the state where a game could enter a “win” state (i.e., game time, payout time). For example, in a roulette game, the unit game includes a bet time for receiving a bet, a game time during which a ball is rolled and then stopped and a payout time during which a payout is awarded.

The “game value” includes a medal, a coin, a gaming ball, money, bill, a magnetic card and the like. The “base payout” is a payout that is awarded based on an execution result of a game and a game value bet. For example, in a roulette game, the game value is a payout that is determined on the basis of a payout rate, which is set in a bet area corresponding to a mark (win mark) corresponding to a stop position of a ball after the ball rolls in a roulette unit, and a game value bet on the bet area.

The “special payout” means a bonus that is paid out irrespective of the game value bet. A JACKPOT may be set as a special payout. In the mean time, the “JACKPOT” means that some of the game values bet are subtracted and accumulated and all or a part of the game values accumulated is awarded when a “win” state is resulted.

The “possible target” means a terminal device 103 having obtained a right for participating in a lottery for the special payout (hereinafter, lottery right). The lottery right is a right that is determined by means of a random selection. The possible target is set based on a bet. A setting type based on a bet may be a type based on a degree of a game value bet or a type in which a bet is made on a side bet area provided for a possible target. The “special payout target” means a terminal device 103 to which a special payout selected from the possible targets is awarded.

The gaming machine 101 structured as described above executes a playing method comprising the steps of awarding a base payout based on an execution result of a game and a game value bet, for each of a plurality of terminal devices 103 each of which receives a bet for a game and awards a payout; setting a possible target for a special payout, based on the respective bets in the terminal devices 103; when the possible target is set, displaying image data so as to specify a terminal device 103 of the possible target; randomly selecting a special payout target from a group of one or more possible targets; and awarding a special payout in the terminal device 103 of the special payout target.

Thus, according to the gaming machine 101 and the playing method, when a possible target for a special payout is set based on the respective bets in the terminal devices 103, the image data is outputted to the display device so as to specify the terminal device 103 as the possible target. That way, a player who operates the terminal device 103 set as the possible target is informed that the player stands a chance of receiving a special payout. As a result, since it is possible to have a player be aware during a game that the player stands a chance of winning a special payout in addition to a base payout depending on a game result, it is possible to award a special payout in a form suitable for a multi participant-type game having the terminal devices 103.

Further, the gaming machine 101 has such a structure that a lottery right to a special payout based on a bet for a roulette game is obtained and a lottery is performed while displaying the lottery right obtained. In other words, the gaming machine 101 includes: a roulette unit (gaming machine main body 102) that executes a roulette game in which a ball rolls on a wheel having marks disposed thereon; terminal devices 103 each of which has several bet areas corresponding to at least one mark, and receives a bet on the bet areas and awards a payout; a display device 104 that displays image data relating to the roulette game; and a controller 105. The controller 105 is configured to execute a program that operates as described in steps of (b1) to (b6).

Specifically, in a step of (b1), the controller sets, as a win mark, a mark corresponding to a stop position of the ball after the ball rolls in the roulette unit. In a step of (b2), the controller awards to each terminal device 103 a base payout based on a payout rate set for a bet area corresponding to the win mark and a game value bet on the bet area. In a step of (b3), the controller determines whether to set each of the terminal devices 103 as a possible target for a special payout, based on the respective bets in the terminal devices 103. In a step of (b4), when the possible target is set, the controller outputs the image data to the display device so as to specify the terminal device 103 of the possible target. In a step of (b5), the controller randomly selects a special payout target from a group of one or more possible targets. In a step of (b6), the controller awards a special payout in the terminal device 103 of the special payout target.

According to the above structure, when a possible target for a special payout is set based on the respective bets in the terminal devices 103, the image data is outputted to the display device 104 so as to specify the terminal device 103 of the possible target. That way, a player who operates the terminal device 103 set as the possible target is informed that the player stands a chance of receiving a special payout. As a result, since it is possible to have a player be aware during a game that the player stands a chance of winning a special payout in addition to a base payout depending on a game result, it is possible to award a special payout in a form suitable for a multi participant-type roulette game having the terminal devices.

Furthermore, the gaming machine 101 may have such a structure that a lottery right for a special payout is obtained by a bet of a predetermined number or more game value. To be more specific, the controller 100 may have a structure to execute a program that operates as described in steps of (c1) to (c6).

In a step of (c1), the controller sets, as a win mark, a mark corresponding to a stop position of the ball after the ball rolls in the roulette unit. In a step of (c2), the controller awards to each terminal device 103 a base payout based on a payout rate set for a bet area corresponding to the win mark and a game value bet on the bet area. In a step of (c3), the controller calculates a summed value of game values bet placed by the terminal devices 103, respectively. In a step of (c4), the controller sets, as a possible target, a terminal device having the summed value of the game values, which is a predetermined value or more. In a step of (c5), when the possible target is set, the controller outputs the image data to the display device 104 so as to specify the terminal device 103 as a possible target. In a step of (c6), the controller randomly selects a special payout target from a group of one or more possible targets. In a step of (c7), the controller awards a special payout in the terminal device 103 set as the special payout target.

According to the above structure, since it is possible to obtain a lottery right to a special payout by a bet of a predetermine or more game value as well as to award a special payout in a form suitable for a multi participant-type roulette game having the terminal devices 103, it is possible to enable to the player to positively make a bet.

Furthermore, the gaming machine 101 may be structured to have a player be aware of the contents of the special payout by a special payout symbol. To be more specific, the controller 100 may be configured to execute a program that operates as described in steps of (d1) to (d7).

In a step of (d1), the controller sets, as a win mark, a mark corresponding to a stop position of the ball after the ball rolls in the roulette unit. In a step of (d2), the controller awards to each terminal device 103 a base payout based on a payout rate set for a bet area corresponding to the win mark and a game value bet on the bet area. In a step of (d3), the controller determines whether to set each of the terminal devices 103 as a possible target for a special payout, based on the respective bets in the terminal devices 103. In a step of (d4), when the possible target is set, the controller randomly selects one special payout symbol among the special payout symbols and displays the one special payout symbol on the display device 104. In a step of (d5), when the possible target is set, the controller outputs the image data to the display device 104 so as to specify the terminal device 103 as the possible target. In a step of (d6), the controller randomly selects a special payout target from a group of one or more possible targets. In a step of (d7), the controller awards a special payout corresponding to the special payout symbol in the terminal device 103 set as the special payout target.

According to the above structure, it is possible to award a special payout in a form suitable for a multi participant-type roulette game having the terminal devices 103. Furthermore, when a possible target is set, one special payout symbol is randomly selected among the special payout symbols and is displayed on the display device 104, so that a player is able to recognize the contents of a special payout in the form of the special payout symbol. This further interests the player in a special payout in the roulette game.

In a step of (e8), the controller randomly selects a special payout target from a group of one or more possible targets. In a step of (e9), the controller awards a special payout corresponding to the special payout symbol in the terminal device 103 of the special payout target.

(Operations of the Controller 105)

An operation of a game controller 100 will be described. First performed is an operation of a bet time of FIG. 1. On the display device 104 of the terminal device 103 are displayed image data and a bet area relating to a roulette game. When a bet on a bet area corresponding to a pressed location of the touch panel 50 is received, a terminal signal including the terminal data such as the terminal number of the terminal device 103, a bet type, a bet-number (game value) and the like is outputted to the bet receiving unit 112. When the bet receiving unit 112 receives the terminal signal, the terminal data included in the terminal signal is stored in the bet memory 113.

Next, the terminal data of the bet-number stored in the bet memory 113 is read out by the bet-number summing unit 116. Then, a summed value of the bet-numbers is calculated. When the calculation of the summed value of the bet-numbers for all the terminal devices 103 is carried out, the summed value of the bet-numbers is stored in the summed bet-number memory 117. The possible target setting unit 118 determines whether the summed value stored in the summed bet-number memory 117 is a predetermined value or more. When it is determined that the summed value is a predetermined value or more, the terminal number having the summed value is set as a possible target.

When a possible target is set, the special payout symbol determining unit 122 randomly selects one special payout symbol among the special payout symbols stored in the special payout symbol memory 121. Then, the determined special payout symbol is displayed on the display device 104 of the terminal device 103. The detailed display will be described later. Meantime, a state of selecting a special payout symbol from the several types of the special payout symbols may be displayed on the display device 104.

Like this, when a possible target for a special payout is set on the basis of a summed value of the bet-numbers (game values) bet in the respective terminal devices 103, the image data is outputted on the display device 104 so as to specify the terminal device 103 of the possible target. That way, a player who operates the terminal device 103 set as the possible target is informed that the player stands a chance of receiving a special payout. As a result, since it is possible to have a player be aware during a game that the player stands a chance of winning a special payout in addition to a base payout depending on a game result, it is possible to award a special payout in a form suitable for a multi participant-type roulette game having the terminal devices 103. Furthermore, since a lottery right to the special payout can be obtained by a predetermined or more bet-number, it is possible to enable to the player to positively make a bet.

Further, when a possible target is set, the special payout target determining unit 119 randomly selects a special payout target from a group of one or more terminal numbers of the possible targets. The determined special payout target is displayed on the display device 104 of the terminal device 103. In the mean time, during a period for which a special payout target is selected, a premonition image may be displayed on the display device 104. The specific display will be described later.

Thus, when a possible target is set, one special payout symbol is randomly selected from the several types of the special payout symbols and is displayed on the display device 104, so that a player is able to recognize the contents of a special payout in the form of the special payout symbol. This further interests the player in a special payout in the roulette game.

Then, an operation is started in the game time from the middle of the bet time. In the roulette unit 3, a roulette game is started. In other words, a ball rolls on a wheel having several marks disposed thereon. Then, when the ball is stopped and the roulette game is thus over, a mark corresponding to a stop position of the ball is obtained. The mark is outputted to the win mark setting unit 111. When the win mark setting unit 111 receives the mark outputted from the roulette unit 3, it sets the mark as a win mark. Thus, the game time is over. Meantime, the bet time is over before the game time is over.

When the game time is over, an operation is started in a payout time. The win mark is outputted to the base payout instruction unit 114. When the win mark is inputted to the base payout instruction unit 114, the base payout instruction unit 114 obtains the terminal data from the bet memory 113 and the bet type and the payout rate from the payout rate memory 115. Then, based on the payout rate set for the bet area corresponding to the win mark and the bet-number bet on the bet area, a base payout is calculated. Then, the base payout is paid out in the terminal device 103 corresponding to the terminal number.

Further, when the win mark is set in the win mark setting unit 111, a special payout corresponding to the special payout symbol of the special payout symbol determining unit 122 is paid out in the terminal device 103 having the terminal number of the special payout target inputted from the special payout target determining unit 119.

(Mechanical Structure: Schematic Structure)

The stations 4 correspond to the terminal devices 103 of FIG. 2 and are disposed around the roulette unit 2. To be more specific, 12 (twelve) stations 4 are disposed to surround the roulette unit 3. The station 4 serves as a bet unit for receiving a bet operation of a player and a payout unit for awarding a medal. The bet operation is an operation that a player predicting a win number of the roulette unit 3 inputs the contents such as number corresponding to the predicted win number.

The electric light indicator 5 has a JP amount indicator 15. The JP amount indicator 15 is mounted on a top of the electric light indicator 5. Thus, the JP amount indicator 15 allows all players who play a game in the stations 4 to see the display contents.

The JP amount indicator 15 displays a jackpot (JP) amount that is a special payout. Here, the roulette gaming device 1 accumulates 0.5% of credits that are bet in a roulette game using a BET screen 61 in the twelve stations 4 and stores the accumulated credit as a jackpot. The credit of the jackpot is paid out to a predetermined station 4 when a special payout is determined by lot. Meanwhile, the “win” means that a “win” state is resulted.

Further, the roulette gaming device 1 has a server 13. The server 13 corresponds to the controller 105 of FIG. 2. The server 13 is disposed at a corner part 12 of the cabinet 2. The server 13 is received in an inner space of the corner part 12. The inner space of the corner part 12 can be opened/shut by means of a corner door 14 having an authentication key attached. The corner door 14 is typically shut so that a player cannot operate the server 13. In the mean time, in the operation of the server 13, the corner door 14 is opened by operating an authentication key. Thus, the server 13 is operated from an outside of the cabinet 2, so that various settings of the roulette gaming device 1 can be performed.

The win determining device 86 is a device for determining the numbered pocket 23 having received the ball 27. Further, the roulette unit 3 has the ball collection device that is not shown. The ball collection device is a device for collecting the ball 27 on the wheel 22 after a roulette game is over. In the mean time, since the ball insertion device, the win determining device and the ball collection device have been already known, the detailed descriptions thereof will be omitted.

In the roulette unit 3 structured as described above, when a ball 27 is introduced on the frame 21 by the ball insertion device, the guide wall 29 guides the ball 27 against the centrifugal force of the ball 27, thereby enabling the ball 27 to roll. When the centrifugal force is decreased as the rotation speed of the ball 27 is lowered, the ball 27 is rolled down along the inclined surface of the frame 21, is moved to the inside and reaches the wheel 22 being rotated. The ball 27, which is rolling-introduced onto the wheel 22, passes over the numbered plates 25 at the periphery of the wheel 22 and then is received in any one of the numbered pockets 23. As a result, the number indicated on the numbered plate 25 corresponding to the numbered pocket 23 having the ball 27 received therein is determined by the win determining device 86, so that a win number is determined.

The image control CPU determines an image to be displayed on the image display device 8 from the dot data previously stored in the image ROM, in accordance with an image control program previously stored in the program ROM, based on parameters set in the station control CPU 91. Further, the work RAM includes a temporary memory unit to be used when the image control program is executed in the image control CPU. Further, the VDP forms an image relating to contents of display determined in the image control CPU and outputs the image on the image display device 8. In the mean time, the video RAM includes a temporary memory unit to be used when an image is formed in the VDP.

Further, a touch panel 50 is attached on a front of the image display device 8. Operation information of the touch panel 50 is transmitted to the station control CPU 91. On the touch panel 50, a player makes a bet operation with chips in the BET screen 61. To be more specific, a player operates the touch panel 50 with regard to a selection of the bet area 72, an operation of a unit BET button 61 and the like, and the operation information is transmitted to the station control CPU 91. Based on the information, the current bet information of a player (a bet area indicated in the BET screen 61 and the number of chips bet) is stored in the RAM 93 at all times. Furthermore, the bet information is transmitted to the server control CPU 81 and is stored in the bet information memory area of the RAM 83.

Furthermore, a sound output circuit 96 and a speaker 10 are associated with the station control CPU 91. The speaker 10 generates a variety of effect sounds when performing various effects, based on an output signal from the sound output circuit 96.

Further, a medal sensor 97 is associated with the station control CPU 91. The medal sensor 97 detects medals inserted from the medal insertion slot 6, calculates the inserted medals and transmits a result thereof to the station control CPU 91. The station control CPU 91 increases the credit-number possessed by a player, which is stored in the RAM 93, based on the transmitted signal.

Further, a WIN lamp 11 is associated with the station control CPU 91. When the chip bet in the BET screen 61 is determined to make a win or JP, the station control CPU 91 turns on/off the WIN lamp 11 in a predetermined color.

(Data Table)

In the followings, a payout management table of FIG. 8 will be described. The data of the payout management table is stored in the ROM 82 of the server 13 shown in FIG. 6. The payout management table has a column of numbers, a column of bet types and a column of payout rates. The data of numbers such as “1”, “2”, “3” and the like are stored in the column of numbers. The data showing bet types such as “Straight”, “Split”, “Street” and the like are stored in the column of bet types. The bet types will be specifically described later. The data showing the payout rates such as “35:1”, “17:1”, “11:1” and the like are stored in the column of payout rates, correspondingly to the bet types. Thus, when a bet is made in a bet type of “Straight”, 35 pieces will be paid out per 1 piece bet.

In the followings, a station management table of FIG. 9 will be described. In the mean time, the data of the station management table is stored in the RAM 83 of the server 13 shown in FIG. 6. The station management table has a column of stations, a column of bet information having a column of bet types and a column of bet-numbers and a column of possible targets. The column of stations stores the machine number data inherent to each station 4. The column of bet types stores the bet type data such as “Straight” as described above. The column of bet-numbers stores the number of pieces bet such as “20.” The column of possible targets stores the data showing whether a possible target has a possibility that a special payout will be awarded thereto. In the mean time, the “1” in the column of possible targets shows that it is set as a possible target and “0” shows that it is not set as a possible target.

Thus, for example, in the station 4 having a machine number of “1”, a bet is made in the bet type of “Straight” and “Corner”, a bet-number for each bet type is 20 pieces and it is shown the possible target is “1.” Further, in the station 4 having a machine number of “2”, a bet is made in the bet type of “Red”, a bet-number for the bet type is 15 pieces and it is shown the non-possible target is “0.”

(Display States of the Image Display Device 8)

In the followings, display states of the image display device 8 will be specifically described with reference to FIGS. 10 to 15. FIG. 11 shows a state that a possible target is set and a special payout symbol is determined by lot, resulting from a predetermined number or more bet. In a display screen of the state, a BET screen 61 having a table-type betting board 60 is displayed. A player can operate the BET screen 61 to bet a chip using the credits possessed.

In the table-type betting board 60 that is displayed in the BET screen 61, the 38 numbers of “0,” “00,” and “1” to “36” are arranged in a grid form. Further, special bet areas for indicating “odd number”, “even number”, “types of colors of numbered plates (red or black)” and “a predetermined range of numbers (for example, “1” to “12”) to bet a chip are also arranged in a grid form.

At a lower part of the table-type betting board 60, a result history indicator 65, a special payout symbol indicator 62, a unit BET button 66, a cashout result indicator 67 and a credit-number indicator 68 are sequentially displayed from left of the screen. The result history indicator 65 displays, in a list form, results of win numbers up to the previous games (here, one game is a series of operations that a player performs a bet in each of the stations 4, a ball 27 is dropped in the numbered pocket 23 and a credit is paid out based on a win number)

At this time, when one game is over, a win number is additionally displayed from top and a history of maximum 16 win numbers can be checked.

The letters of “CHANCE SLOT” are displayed near to the special payout symbol indicator 62. When a possible target is set, the special payout symbol indicator 62 variably displays the special payout symbols in a time period for which it randomly selects one special payout symbol from the several types of special payout symbols, and stops the determined special payout symbol. To be more specific, as shown in FIGS. 1 and 10, a summed value of bet-numbers is 15 pieces or more, the four types of image data of “MEGA”, “MAJOR”, “MINI” and “LOSS” are sequentially switching-displayed in the special payout symbol indicator 62. The condition of starting the switching-display, i.e., the condition of setting a possible target is such that a summed value of bet-numbers is a predetermined number or more, such as 15 pieces or more.

This enables a player who operates the station 4 to recognize that a possible target for which a special payout will be awarded is set. As a result, it is possible to have a player be aware during the roulette game that the player stands a chance of winning a special payout in addition to a base payout depending on the game result. Furthermore, since it is possible to obtain a lottery right to the special payout by the bet of a predetermined game value or more, it is possible to enable to the player to positively make a bet.

In the mean time, “MEGA”, “MAJOR”, “MINI” and “LOSS” indicate a payout degree. In other words, “MEGA” means a maximum payout-number, “MAJOR” means a middle degree of a payout-number, “MINI” means a small degree of a payout-number and “LOSS” means no payout. For example, for “MEGA”, a payout is performed using all of JP (100%). For “MAJOR”, a payout is performed using 70% of JP. For “MINI”, a payout is performed using 40% of JP.

Further, the unit BET buttons 66 are provided for a player to bet a chip on bet areas 72 (above the grids of number and mark or above lines forming a grid) indicated by the player. The unit BET button 66 includes a 1 BET button 66A, a 5 BET button 66B, a 10 BET button 66C and a 100 BET button 66D. A player first pushes the screen with a finger, thereby indicating a bet area 72, on which a bet is made, with a cursor 70. At this state, when the player pushes the 1 BET button 66A, the player bets a chip in a unit of one piece (whenever the 1 BET button 66A is pushed with a finger, the bet-number is increased in an order of “1”-->“2”-->“3” . . . ). Further, when the player pushes the 5 BET button 66B, the player bets chips in a unit of five pieces (whenever the 5 BET button 66B is pushed with a finger, the bet-number is increased in an order of “5”-->“10”-->“15” . . . ). Further, when the player pushes the 10 BET button 66C, the player bets chips in a unit of ten pieces (whenever the 10 BET button 66C is pushed with a finger, the bet-number is increased in an order of “10”-->“20”-->“30” . . . ). Furthermore, Further, when the player pushes the 100 BET button 66D, the player can bet chips in a unit of 100 pieces (whenever the 100 BET button 66D is pushed with a finger, the bet-number is increased in an order of “100”-->“200”-->“300” . . . ). Accordingly, even when many chips are bet, an operation thereof stays simple.

Further, the cashout result indicator 67 displays the number of chips bet by a player in a previous game and the cashout credit-number. Here, the subtraction of the bet-number from the cashout credit-number results in a credit-number that is newly obtained by a player in a previous game.

Furthermore, the credit-number indicator 68 displays the number of credits possessed by a current player. When a chip is bet, the credit-number is decreased in proportional to the bet-number (one credit for one bet). Further, when a win is determined for the chip bet and the cashout of credits is performed, the credit-number is increased as the cashout-number. In the mean time, when the credit-number possessed by a player is 0, the game is over.

A BET time indicator 69 is disposed above the table-type betting board 60. The BET time indicator 69 displays a remaining time period for which a player can make a bet. When a bet operation is received, “20” is displayed and the number is decreased by 1 every one second. When the number is “0,” a bet operation is not received. Further, in each of the stations 4, when the bet time of the player is 5 seconds, the ball insertion device is driven to insert the ball 27 on the roulette wheel.

Furthermore, a JP indicator 73, which displays the credit-number of JP accumulated up to now, is disposed at the right of the BET time indicator 69. Here, the JP indicator 73 displays a value to which 0.5% of credits bet in the twelve stations 4 is accumulatively added and is common to all the stations 4. When a special payout, which is carried out in combination with a roulette game under predetermined condition, is made, a win of JP is determined and the credit-number corresponding to a special payout symbol among the JP is paid out. In the mean time, the credit-number of JP that is accumulated up to now is also displayed on the JP amount indicator 15 of the electric light indicator 5.

Further, a cursor 70 showing the bet area 72 selected by a player is displayed on the table-type betting board 60. Additionally, a chip mark 71 showing the number of chips that are bet up to now and the bet area 72 is displayed and the number shown on the chip mark 71 indicates the number of chips bet.

When a player wants to make a bet in the BET screen 71 structured as described above, the player indicates a bet area 72 to be bet (above the grids of number and mark or above lines forming a grid) and directly pushes it with a finger. As a result, the cursor 70 is moved to the bet area 72 indicated. Then, when the unit buttons of the unit BET buttons 66 (1 BET button 66A, 5 BET button 66B, 10 BET button 66C, 100 BET button 66D) are pushed, the chips as the unit number are bet on the bet area 72 indicated. For example, when the 10 BET button 66C is pushed four times, the 5 BET button 66B is pushed one time and the 1 BET button 66A is pushed three times, 48 chips can be bet.

FIG. 12 shows a state that a special payout symbol is determined by lot. In the display screen of the state, a bonus win indicator 63 appears on the table-type betting board 60. The bonus win indicator 63 displays a special payout symbol that is determined by lot in the special payout symbol indicator 62. In other words, the bonus win indicator 63 displays a letter image having combined the “special payout symbol”, which is determined by lot, and “JACKPOT CHANCE”.

Thus, when a possible target is set, one special payout symbol is randomly selected from the several types of the special payout symbols and is displayed on the special payout symbol indicator 62 and the bonus win indicator 63, so that contents of the special payout can be recognized to a player. This further interests the player in a special payout in the roulette game.

FIG. 13 shows a state that a special payout target is being determined by lot among the possible targets. In the display screen of the state, a letter image displayed on the bonus win indicator 63 is rotated, thereby displaying whether a payout corresponding to the special payout symbol will be awarded or not. Thus, during the roulette game, it is possible to enable a player to recognize a possibility that a special payout corresponding to a special payout symbol will be awarded, in addition to a possibility that a base payout based on a game result will be awarded. In the mean time, the rotation of a letter image on the bonus win indicator 63 is continued until the game time is over.

FIG. 14 shows a state that a special payout target is determined by lot. In other words, a letter image of “WIN” is displayed with a special payout symbol on the bonus win indicator 63. FIG. 15 shows a state that a special payout target is not determined. In other words, a letter image of “SORRY, MAY BE NEXT” is displayed on the bonus win indicator 63.

(Bet Types)

In the followings, the bet types will be described with reference to the betting board 60 of FIG. 12. For example, as shown in FIG. 12, the chip mark 71 of “7”, which is put on the grid of “18”, indicates that 7 chips are bet on the number “18.” Like this, the bet type in which a bet is made on one number only is referred to as a “Straight bet.”

The chip mark 71 of “1”, which is put on an intersection of the grids of “5”, “6”, “8” and “9”, indicates that one chip is bet while covering the four numbers of “5”, “6”, “8” and “9.” Like this, the bet type in which a bet is made while covering the four numbers is referred to as a “Corner bet.”

Further, there is a bet type of “Split bet” in which a bet is made while covering two numbers above a line between the two numbers. Further, there is a bet type of “Street bet” in which a bet is made while covering three numbers at ends of the one row of the numbers (one column in the vertical direction). Further, there is a bet type of “Five bet” in which a bet is made while covering five numbers of “0”, “00”, “1”, “2” and “3” above a line between “00” and “3”.

There is a bet type of “Line bet” in which a bet is made while covering six numbers (for example, “13”, “14”, “15”, “16”, “17” and “18”) between two rows of the numbers (two columns in the vertical direction). There is a bet type of “Column bet” in which a bet is made while covering 12 numbers above the grid of “2 to 1”. There is a bet type of “Dozen bet” in which a bet is made while covering 12 numbers above the grids of “1st 12”, “2nd 12” and “3rd 12”, respectively.

Furthermore, there is a bet type of “Red or Black bet” in which a bet is made on the color of the numbered plate (“red” or “black”) using the six grids provided at the lowest end of the table-type betting board 60. There is a bet type of “Odd or Even bet” in which a bet is made on the odd or even numbers. There is a bet type of “Low or High bet” in which a bet is made while 18 numbers using the numbers of 18 or less or 19 or more. Here, the bet types have different payouts (payout rates) of the credits per one chip, which are awarded when the chip bet is determined as a win.

(Processing Operations)

In the followings, the operations will be described, based on a game processing program of the server that is executed by means of the server control CPU 81 of the roulette gaming device 1, and a game processing program of the station that is executed by the station control CPU 91 of the station 4. In the mean time, the programs that are shown in flow charts of FIGS. 16 to 19 are stored in the ROM 82 or RAM 83 of the server 13 or the ROM 92 or RAM 93 of the station 4 and executed by the server control CPU 81 or station control CPU 91.

(Station Side Game Process)

In the followings, a station side game process will be described with reference to FIG. 16. Firstly, it is determined whether a medal or bill is inserted by a player, based on a detection signal of the medal sensor 97 (S1). When a medal or bill is not inserted (S1, NO), this routine is ended, and the step of S1 is repeatedly executed and the standby mode is continued until a medal or bill is inserted.

In the mean time, when a medal or bill is inserted (S1, YES), the credit data of an amount of money corresponding to the number of pieces inserted is recorded in the RAM 93, so that the credit is added (S2). Then, a medal detection signal indicating that a medal or bill is inserted is transmitted to the server 13 (S3).

Then, in the image display device 8 of the station 4, the BET screen 61 of FIG. 11 is displayed and a bet time for which a player can bet a chip is started (S4). Then, a bet operation is executed (S5). Thus, a player who takes part in a game can operate the touch panel 50 to make a bet on the BET area 72 relating to a number that the player predicts, during the bet time for which a bet operation can be received. In the mean time, the detailed bet types using the BET screen 61 have been already described. Therefore, the descriptions thereof will be omitted.

Further, the player can take part in a game in the course of the game after the bet time is started. In the roulette gaming device 1 of this embodiment, maximum 12 players can play a game. Furthermore, when this time game is carried out following the previous game, a bet operation is received just after the previous game is over.

When a bet operation is carried out, a bet information signal including the contents of the bet operation is transmitted to the server 13 (S6). Then, it is determined whether the bet time is over or not (S7). When the bet time is not over (S7, NO), the process is transited to the step of S5 and the state of receiving a bet operation is maintained. When the bet time end signal is received from the server 13, an image showing that the bet time is over is displayed on the image display device 8 of the station 4 and the process of receiving a bet operation on the touch panel 50 is ended (S8).

Then, when a win number signal, which is a game result of the roulette game, is received from the server 13, a process such as one which emphasizes the win number is carried out, so that an effect for notifying the win number of the roulette game is performed (S9). When a payout result signal is received from the server 13, a credit is paid out on the basis of the payout result signal. To be more specific, the credit data of a base payout and a special payout is stored in the RAM 93. When the cashout button 48 is pressed, the medals (typically, one medal per one credit) according to the credit-number currently stored in the RAM 93 are paid out from the medal payout slot 9 (S10). Then, a standby mode is made. When a unit game end signal is received from the server 13 (S11), this routine is ended. Then, a process of receiving a bet operation in a next unit game is re-started.

(Chance Slot Process)

While the station side game process is performed, a chance slot process of FIG. 17 is performed in the station 4 at the same time. In other words, depending on whether a possible target signal from the server 13 is received, it is determined whether to participate in a bonus (A1). When it is determined not to participate in a bonus (A1, NO), this routine is ended. Thus, the step of A1 is re-executed, so that the determination of whether to participate in a bonus is repeated.

When it is determined to participate in a bonus (A1, YES), a slot rotation is started in the special payout symbol indicator 62, as shown in FIGS. 1 and 12. To be more specific, as shown in FIG. 10, the four types of the image data of “MEGA”, “MAJOR”, “MINI” and “LOSS”, which are special payout symbols, are sequentially switching-displayed. Then, it is determined whether a bet time is over or not (A3). When a bet time is not over (A3, NO), the step of S2 is re-executed and the slot rotation of the special payout symbols is continued on the special payout symbol indicator 62.

In the mean time, when a bet time is over (A3, YES), a bonus type corresponding to the special payout symbol is registered, based on a bonus type signal transmitted from the server 13. In other words, one of “MEGA”, “MAJOR”, “MINI” and “LOSS” is registered (A4). Then, as shown in FIG. 12, the slot rotation of the special payout symbol indicator 62 is stopped and the special payout symbol corresponding to the bonus type registered is stopped on the special payout symbol indicator 62 (A5).

Then, the bonus win indicator 63 appears on the table-type betting board 60. Then, a letter image having combined the special payout symbol” stopped on the special payout symbol indicator 62 and “JACKPOT CHANCE” is displayed on the bonus win indicator 63 (A6). Thus, a player is able to be aware of standing a chance of winning a special payout corresponding to the “special payout symbol”.

The display of the letter image on the bonus win indicator 63 is continued until a first effect time has elapsed, through a waiting of the first effect time (A7). After that, an effect of a bonus win is performed. Specifically, as shown in FIG. 13, the letter image displayed on the bonus win indicator 63 is rotated (A8). When a special payout target signal is received from the server 13, a display based on the special payout target signal is made. To be more specific, when a special payout is determined by lot, a letter image of “WIN” is displayed with the special payout symbol on the bonus win indicator 63, as shown in FIG. 14. In the mean time, when a special payout is not determined, a letter image of “SORRY, MAY BE NEXT” is displayed on the bonus win indicator 63, as shown in FIG. 15 (A9). Then, the station enters the standby mode. When a unit game end signal is received from the server 13 (A10), this routine is over.

(Server Side Game Processing)

In the followings, a server side game processing will be described with reference to FIG. 18. It is determined whether a player inserts a coin or bill by receiving a medal detection signal transmitted from the station 4 (B1). When a medal detection signal is not received (B1, NO), this routine is ended. Thus, the step of B1 is repeated until a medal and the like is inserted in the station 1.

When a medal and the like is inserted in the station 3 (B1, YES), there is started a measurement of a bet time period, which is a reception period for which a player can make a bet, from the time at which the first player inserts a medal or bill (B2). In the mean time, when this time game is executed following the previous game, a bet time is started just after the previous game is over. A player who takes part in a game can operate the touch panel 50 for the bet time period, thereby betting the chips on the bet area 72 related to the number predicted by the player.

Then, it is determined whether the remaining bet time is 5 seconds (B3). In the mean time, the remaining bet time is also displayed on the image display device 8 by means of the BET time indicator 69. When it is determined that the remaining bet time is not 5 seconds (B3, NO), the step of S3 is re-executed, so that the standby mode is kept until the remaining bet time is 5 seconds. Meantime, when it is determined that the remaining bet time is 5 seconds (B3, YES), a roulette lottery process is executed in the roulette unit 3.

To be more specific, the ball insertion device is driven, so that the ball 27 is inserted into the roulette wheel (B4). Then, the driving motor is driven, so that the wheel 22 is rotated at a predetermined rotation speed in a direction opposite to the ball insertion direction. The inserted ball 27 rolls on the roulette wheel along the guide wall 29. Then, when the rotation speed is lowered and the centrifugal force is thus reduced, the ball is dropped along the inclined surface of the frame 21 and thus reaches the wheel 22 being rotated (refer to FIG. 4). The ball 27, which reaches the wheel 22, continues to pass over the numbered plates 25 at the periphery of the wheel 22 and is introduced into one of the numbered pockets 23 and the number (any one of “00”, “0” and “1” to “36” in FIG. 4) shown on the numbered plate 25 corresponding to the numbered pocket 23 into which the ball 27 is introduced becomes a win number.

When the roulette lottery process is carried out as described above, a bet information signal is received from the station 4 (B5). The bet-number and the bet type included in the bet information signal are registered in the station management table of FIG. 9 (B6). Then, it is determined whether the bet time is over (B7). When it is determined that the bet time is not over (B7, NO), the standby mode continues until the bet time is over. In the mean time, when it is determined that the bet time is over (B7, YES), a bet time end signal is transmitted to the station 4 (B8).

Then, a jackpot accumulation process is executed (B9) To be more specific, the bet information made by a player in each of the stations 4, i.e., the information of the indicated bet area 72 and the number of chips (bet-number) bet on the indicated bet area 72 and the bet type is received and stored in the bet information memory area of the RAM 83. Then, the credits, which correspond to 0.5% of the total credits bet in the stations 4, are accumulated and added to the JP amount that is recorded in the JP accumulation memory area 83V of the RAM 83. Correspondingly to this, the display of the JP amount indicator 15 and the JP indicator 73 is updated.

Then, when the ball 27 is received in the numbered pocket 23 in the roulette unit 3, a win determining device 86 is driven. Thus, it is detected a win number of the roulette unit 3 in this time game (B10).

Then, the win number signal including the information of the win number is transmitted to the stations 4 (B11). Then, the bet information and the win number of the stations 4 are used to determine whether the chips respectively bet in the stations 4 are determined as a win (B12). Continuously, a payout calculation process is executed. In the payout calculation process, the won chips bet on the win number are recognized for each station 4 and a sum of the payouts of the credits to be respectively paid out to the stations 4 is calculated with the payout rates for each bet area 72, which are stored in the ROM 82 in a payout management table form of FIG. 8, i.e., the credit-number to be paid out per one chip (one bet) (B13).

Then, it is executed a process of transmitting a payout result signal including a payout result of the credits of the roulette game, based on the payout calculation process. To be more specific, the payout result signal including the credit data of a base payout corresponding to the payout amount of the roulette game is transmitted to the station control CPU 91 of the station 4 that is determined to be a win in the roulette game (B14).

Then, the ball collection device provided below the wheel 22 is driven, so that the ball 27 on the wheel 22 is collected. The collected ball 27 is adapted to be inserted in the wheel 22 of the roulette unit 3 in a next or more game (B15). Then, a unit game end signal is transmitted to the station 4 (B16) and this routine is ended.

(Bonus Lottery Process)

While the game process is performed in the server 13, a bonus lottery process of FIG. 19 is performed at the same time. In other words, the station management table of FIG. 9 is referred to and it is determined whether the bet-number in each station 4 is a predetermined value or more, such as “15” (C1). When it is determined the bet-number is not a predetermined value (C1, NO), this routine is over and the step of C1 is repeatedly executed.

When it is determined the bet-number is a predetermined value (C1, YES), a possible target is determined for which a special payout will be awarded and “1” is set in the corresponding location of the possible target column of FIG. 9 (C2). Then, a possible target signal is transmitted to the station 4 having the machine number for which “1” is set (C3).

Then, it is determined whether a bet time is over or not (C4). When a bet time is not over (C4, NO), the step of C1 is re-executed. When a bet time is over (C4, YES), a bonus lottery is performed. To be more specific, one bonus type is randomly selected from the four bonus types of “MEGA”, “MAJOR”, “MINI” and “LOSS” (C5). Then, the determined bonus type is determined (C6) and a bonus type signal is then transmitted to the station 4 (C7).

Then, a lottery is made to determine whether a special payout target is determined by lot, for all the possible targets. Thereby, depending on the lottery result, all the possible targets may become a special payout target, or alternatively, several possible targets may become a special payout target (C8). Then, a special payout target signal including the lottery result of the special payout target is transmitted to the station 4 that is set as a possible target (C9). After that, a standby mode is made. When a unit game end signal is received from the server 13 (C10), this routine is over.
