The invention relates to games of dice wherein a plurality of dice are shaken or rolled in a container.

Die Structure

Dice have been made in any number of configurations as evidenced by Sieve U.S. Pat. No. 3,208,754. This patent illustrates five different shapes of dice having from four sides to 20 sides; whereas, Cowles U.S. Pat. No. 1,054,341 illustrates a die having 26 sides.

One of the objects of the instant invention is to provide a die and games associated therewith wherein the die is in the form of an icosahedron having twenty sides with two sets of numbers from 1 to 10. In the field of education and child development the numbering system he must learn to live with is one revolving around the base 10, i.e., 1-10 or 0-9. Virtually all commonly used mathematics is developed around this base. By having a series of dice which are numbered from zero through nine, the child can form any number, depending upon the number of dice used. For example, if three dice are used, he can develop any number from 000 to 999. In this way not only can he learn the common numbering system but he can also learn addition, subtraction, division, multiplication, as well as concepts such as "less than" and "greater than." This has not been possible with prior art dice.

Tetrahedron Structure

Another aspect of the invention is the incorporation of a 20-sided die or a group of 20-sided dice in containers. Therefore another object of the invention is to provide a plurality of spheres having platforms wherein the four spheres connected together can be thrown and a pair of dice with an appropriately labeled platform will appear.

While U.S. patents such as Wharton 1,030,554 and Sutherland 2,879,066 illustrate games which have numbered caps or balls on the ends and U.S. patents such as Madan 1,593,907 and Brown 2,528,029 illustrate bodies or cubes having dice therein, nothing in the prior art has provided a series of spheres connected in a tetrahedron manner having platforms and dice therein in the manner illustrated and discussed below.

Shaker Structure

Another aspect of the invention is a dice cup with upper and lower chambers having a platform therebetween which will facilitate the movement of the dice between the two containers wherein a game of chance can be played.

A common thread which runs through the variously discussed inventions is the utilization of a removable platform between a pair of chambers having 20-sided dice therein, the dice having two sets of numbers from zero to ten.

Set out below is a detailed description of the invention.

Die Seen in FIGS. 1 and 2

Referring to FIGS. 1 and 2 a 20-sided die 1 is seen having two sets of numbers from 1-10, one set 3 having circles around the respective numbers and a second set 5 having triangles therearound to distinguish the two sets. When the child throws the die one of the numbers with either a circle or a triangle therearound will appear in the uppermost position. If the child throws two dice he will have a two-digit number. If he throws three dice, he will have a three-digit number, etc.

In a game a fourth die may be provided having a multiplication, division, addition, or subtraction indication thereon. The child would first throw a first icosahedron die, then an instruction die telling him what to do (for example, multiply); and finally throw another icosahedron die which he would then multiply times the first die.

Alternatively, he could throw three icosahedron dice, put them together in a row and come up with a three-digit number.

It will be appreciated that the process of learning mathematics could be made into a game.

Four-sphered Tetrahedron Game Illustrated in FIGS. 3-11

A series of four spheres 10 are connected together to form a tetrahedron as seen in FIG. 3. Each sphere 10 has a platform 12 therein with a mathematical indication 14 in the form of a minus sign, plus sign, division sign and multiplication sign. A pair of icosahedron dice 16 are seen in each of the spheres. The platform 12 is secured to the sides of the sphere by glue or by positioning in a slot as seen at 18 in FIG. 4. Alternatively, the platforms 12 can be formed in such a way as to be free-floating in the sphere. When the tetrahedron is thrown, the uppermost sphere will land in such a manner that the platform 12 (which may be appropriately weighted) will rest in a position horizontal to the ground. The platform 12 can also be formed with a lower portion shaped to conform with space 20, thus assuring that the platform will rest in the proper location.

As seen in FIG. 3 the "minus" sign has landed in the "up" position. Therefore, the child will be instructed to subtract the number zero to nine on one of the dice from a number from zero to nine on the other of the dice.

An alternative modification seen in FIGS. 6-11 illustrates a sphere 22 having a stationary platform 24, the platform having slot 26 therein. Positioned in the center of the slot 26 is an opening 28. The sphere 22 also has an opening in the side 30 whereby a slide closure 32 having a depending portion 34 thereon and a "minus" sign 14 can be slid through the opening 30 into the slot 26 and covering the opening 28. In the bottom of the sphere 22 is a threaded opening 36. By means of slide 32, opening 28 and threaded opening 36 the child or teacher can change the instructional sign 14 and/or the dice in the sphere.

As illustrated in FIG. 8 a tetrahedron bolt 40 is seen having a four-sided central section 42 and four threaded screw members 44 thereon. The four-threaded screw members 44 are designed to be threaded into openings 36 to connect four spheres in an easily detachable manner.

Shaker Illustrated in FIGS. 12-18

Referring now to FIG. 12 a spherical shaker 50 is seen with a platform 52 separating the sphere into an upper chamber 54 and a lower chamber 56. At the base of the lower chamber is an opening 58 having an annular lip 60 thereon. A base cap 62 having an inwardly directed annular lip 64 is snap-fitted onto lip 60 closing the opening 58. The sphere 50 has a side opening 66 to accommodate a handle portion 68 of a slide 70. The slide 70 is positioned in a groove 72 in platform partition 52. Also located within the slide groove 72 is an opening 74. The slide closure 70 has a mathematical or other instruction sign 76 thereon. It will be appreciated that the marking 76 is not necessary and is selectively changeable.

Another modification seen in FIGS. 17 and 18 has correspondingly numbered elements but of a shape having an upper chamber 54' in a frustroconical configuration.

In a game of chance, five dice can be positioned in the upper compartment 54 and shaken, the game being to obtain as many dice with the same number thereon. Normally, five conventional dice numbered "1" to "6" are used. After the dice are shaken, those dice with the same number thereon are noted and removed to the lower chamber by sliding the closure 70 away from opening 74 and allowing the dice to fall therethrough. The dice in the upper chamber are reshaken and any additional numbers identical to those thrown the first time are noted and the total number recorded.

An example of the above would be shaking all five dice in the upper chamber one time. It will be noted that the number "6" appears on two dice. These two dice are removed to the lower chamber through opening 74. The remaining three dice are shaken again and the number of 6's are again noted. In the example used, it may be assumed that one additional "6" appears. Therefore, this player will have three "6's" to his credit.

The next person then takes his turn with all five dice in the upper chamber. It may be assumed that when he shakes the first time he will get three 5's. The three 5's are then removed to the lower chamber and the player shakes the remaining two dice. Now it may be assumed that he obtains one additional 5 on his second shake. He will therefore have four 5's, as opposed to the original player's three 6's. He will therefore win the game.

An advantage of the instant device is that it permits the players to shake the dice without any influence created by their hands on the dice or on the opening of a container normally used to throw the dice onto the table.

While several embodiments of the invention has been described, it will be understood that it is capable of many further modifications and this application is intended to cover any variations, uses, or adaptions of the invention following in general, the principles of the invention and including such departures from the present disclosure as come within knowledge or customary practice in the art to which the invention pertains, and as may be applied to essential features hereinbefore set forth and fall within the scope of the invention or the limits of the appended claims.
