Educational math strategy games and methods of playing the same. The math strategy game may include a game board defining a plurality of spaces, a plurality of dice, and a plurality of distinct sets of game tokens for covering one or more of the plurality of spaces. During game play, a player may roll five dodecahedron dice and select a product of any two dice rolled. A token is placed onto the game board over one of the plurality of spaces matching the product selected. Game play continues until one player or team covers a horizontal, vertical, or diagonal series of adjacent spaces.

A collapsible, self-expanding polyhedron comprises a plurality of side members each connected with an elastic band that is sized to urge each side wall of adjacent side members together to form an expanded configuration. When the polyhedron is compressed on two opposing side members, which causes the other side members to separate into a collapsed configuration, the elastic band expands to a maximum length with maximum tension. Once the compression is released, the at least one elastic band retracts back to a minimum length and urges the side members back into the expanded configuration.

A math learning process uses a first set of dice and a second set of dice. The process includes configuring the first set of dice and the second set of dice to respectively produce equal probabilities of occurrence of two different sums. A first player rolls the first set of dice and records the sum. A second player rolls the second set of dice and records the sum. These steps are repeated until one of the first player and the second player rolls a particular sum a predetermined number of times. Other dice configurations facilitate focus on specific math facts and operations.

The proposed invention relates to a system for electronic dice, i.e., those devices which are in practice used for board games and parlour games with the support of electronic components. The invention comprises a hardware structure for the tracking and remote transmission of the result of the roll of a die adaptable and usable for various types of dice and, if necessary, transferable between different dice casings heterogeneous in shape, functions and mode of use; said structure being programmable to automatically recognize and adapt to the different shape and type of dice in which it is applied and being conveniently applicable for simultaneous and multiple rolls and for further processing of the results. The solution referred to in the patent is realized through a core containing an electronic board structurally similar to that integrated in common commercial electronic dice and comprises an accelerometer, a Radio Frequency transmitter—preferably but not necessarily of the Bluetooth type—a CPU, a battery and a memory for information management and process control. The fact that the core hosting the electronic board can be inserted inside these dice in the form of polyhedral casings by means of a unique interlocking and, therefore, by means of a single possible orientation, allows to know a priori the relative orientation of the electronic board and, in particular, of the accelerometer with respect to the body of the dice or the host casing. Said relative orientation between the core and the possible host dice being predetermined and known, the invention is able to determine the result of the rolls simply knowing the type of die in which the core is housed (hence the number of faces in the case of regular polyhedra and the values which characterize said faces). For each type of dice (i.e., with the varying of the faces, the varying values represented on said faces and any rules of use), one or more tables or look-up-tables are provided, preloaded in the memory of the electronic board of the core so as to know the result of the relative orientation of the accelerometer gravity vector and therefore of the roll of the die upon the varying of the most varied types and areas of application.

The systems and methods herein provide for human- and machine-readable cryptographic keys from dice. In one embodiment, the system places a number of dice into an arrangement to fill a dice grid. The number of dice each contains a number of faces, and each of the faces of the dice includes an image. The system then captures, via a client device, an image of the arrangement. The system generates a cryptographic key from the captured image. This cryptographic key is a human-readable and machine-readable representation of the arrangement in a canonical sequence.

Disclosed is a mathematics learning game system for users to improve upon their mathematics skills. Also disclosed is a method of using the system. The system may include cards, each having three color spots of different colors, and a random number in each color spot, a pair of 20-sided dice with the numbers 1 to 20, each side being of one of the colors of the color spots on the cards, and a timer device. A target number and target color are determined by rolling the dice. Players arrange cards to combine numbers of the target color from the cards into a mathematical expression with a solution as close as possible to the target number. Aspects of the present invention may be embodied as a system, method, or computer program product, such as an app that may operate on a computing device or network.

The present invention relates to a game which can be played with dice or optionally with cards or both. Each of the eight sided dice will have 6 different point values for the first six faces, with each point value forming a suit, with five die per suit. The seventh die face is a “scratch” (which is denoted by a tiger with claws and is considered wild) face. The eighth die face is variable, there are two wilds, two scratches, and one “zap” die face. A winning “hand” or set of rolled dice will have five of a kind in any combination of die face. In an embodiment, a winning hand allows a player to draw a scratch card or lottery ticket, the value of which is determined by scratching, which value determines the value of the winning hand. There are various styles of game play involving the game pieces, with different rule sets for every style.

The invention relates to dice suitable for use in gaming. In particular the invention relates to a new indicator system for use in gaming dice, the indicator system providing a di value. More specifically the invention relate to a di incorporating the indicator system providing a di value, and the use of the di to provide a di value, and a method of using the di.

Methods and systems for designing and manufacturing a mathematically fair N-sided die are disclosed. An example method can comprise selecting an irregular polyhedron to serve as a die, and determining a center of mass of the selected irregular polyhedron die. In an aspect, a size of each face of the irregular polyhedron can be selected such that a solid angle subtended by each face from the center of mass of the selected irregular polyhedron can be equal. In an aspect a system comprising an injection molding apparatus can be used to form the die.

Transparent dice with a void therein filled with a liquid and/or visible matter, so that an entertaining visual aspect is visible through portions of the dice, when the dice are shaken, rolled or otherwise moved. The visual aspect could be a visible swirling motion, moving objects inside the dice, and objects in the liquid. Methods of making the dice are described.
