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.

A strategy board apparatus suited for strategic paintball play is presented. The strategy board apparatus contains a board body and at least one strategy piece. The board body comprises a mounting surface. The mounting surface traverses along the board body. The at least one strategy piece is removably attached and distributed about the mounting surface through a fastening element.

An overlay having artwork printed thereon in a strategic location such that when placed over the front face of a card changes the look and appearance of the original artwork on the front face of the card. In some embodiments, the overlay changes the original text printed on the card (1) to provide a translation of that text into any desired language, or (2) to provide updated rule changes from the rules originally printed on the card, or (3) to provide both a translation as well as updated rule changes, if desired. The overlay may be used with any type of card, but is preferably used with playing cards and trading cards, and is most preferably used with collectible trading cards.

A game for assessing and developing emotional intelligence where the game may comprise: at least one selector configured to indicate one of a plurality of emotions; and a plurality of images wherein each image represents an emotional situation and wherein the one emotion indicated by the at least one selector is assignable to one of the plurality of emotions.

Systems, devices, and methods including one or more code rings, each code ring comprising one or more sides on an outer surface and one or more code ring alignment indentations on an inner surface; and one or more inner combination rings, each inner combination ring comprising one or more inner combination ring alignment protrusions on an outer surface and a combination indentation on an inner surface; where each of the one or more code ring alignment indentations receive each of the one or more inner combination ring alignment protrusions, where each inner combination ring may be removable and rotatable relative to each code ring of the one or more code rings, and where the combination indentation may be proximate an unlocked side of each of the one or more code rings.

An illustrative pattern building and matching card game is described herein. The card game may include a first deck of cards including build cards each illustrating a single graphical element selected from a set of graphical elements, a second deck of cards including pattern cards each illustrating a pattern of multiple graphical elements selected from the set of graphical elements, and game instructions indicating that a number of the build cards and a number of the pattern cards be dealt to each of multiple players, and the players, in turn, play one or more of their build cards attempting to form, in a collaborative build space, patterns illustrated by their pattern cards.

A chess variant includes (a) one of an 8 by 8 board, a 8 by 10 board, or a 10 by 10 board; (b) a conventional chess piece set; and (c) a novel non-conventional chess piece set, wherein the pieces of the non-conventional chess piece set perform non-standard movements with rules associated therewith to govern how the pieces move and capture upon the board. Additionally, the set of rules governing how the rules of movement for the piece can undergo a change when a non-conventional chess piece reaches the furthest rank, akin to the process of promotion in standard chess.

A dice cup used for rolling dice and randomizing the markings shown on the upper side of dice. The dice cup has a flat base and a circumferential side wall that forms a hollow annular shape with a top aperture and that attaches to the base to form a closed bottom. The diameter of the bottom is greater than the diameter of the aperture, whereby the circumferential side wall tapers outward from the aperture to the closed end. Rolling and randomization of the markings on the upper side of the dice is caused by interaction between the dice and (1) protrusions extending upward from the upper surface of the base that have a predetermined size that cause the one or more cubic dice placed inside the dice cup to rest on the corners of each dice, and/or (2) raised surface features on the tapered interior of the side wall.

A multi-layer toy having at least one outer layer adjacent a planar layer or a ball where both the outer layer and the adjacent planar layer or ball each contain related information such that, in play, the information on the outer layer is made to align with the related information on the adjacent planar layer or ball. The information can comprise depictions of objects, things, characters, animals, or words, for a matching game, or the information can comprise numbers for a counting or mental math game. The toy is preferably sized to be hand-held.

A hidden object game, including a plurality of foam blocks to be hidden by at least one first player, a timer to generate a countdown timer based on a number of players in the game, a pair of headphones worn by at least one second player to prevent the at least one second player from hearing surrounding noise, and a blindfold worn by the at least one second player to prevent the at least one second player from seeing.
