Our invention provides an improved set of multi-faced building blocks with the following characteristics: 1) softer edges designed to increase friction of the blocks during the construction process; 2) faces that allow mounting different tiles with variety of designs which provide hints guiding construction of solutions, allowing player to complete puzzles; and 3) mountable tiles that code each face of the building block in order to increase the number of visible solutions within one set of blocks, making the puzzle more versatile. Our invention lets players create and code their own new unique solutions using the mountable tiles. Our invention also allows the player to recognize and track each new solution using the design elements depicted on the mountable tiles. The proposed invention can develop spatial reasoning skills of players and can be used for education or entertainment.

A game apparatus including a plurality of first and second player game pieces, each having a first portion that is a chess piece, such that the plurality of first and second player game pieces include all the pieces for a first and second player, respectively for a game of chess. Each of the plurality of first and second player game pieces has a second portion fixed to a corresponding first portion. Each second portion has a recess so that a cube can be inserted into the recess so the cube cannot be seen from a front of the second portion. The game apparatus may further include a base; a grid; and a first and/or second plurality of insert pieces. The grid and the base form a chessboard pattern of a plurality of grid spaces. Each of the insert pieces fits within a space of the plurality of grid spaces.

Exemplary embodiments of a three-dimensional puzzle having C-shaped members are provided. For example, a three-dimensional puzzle can be provided including a first, second and third C-shaped member each having a first end and an opposing second end, and a first bulbous portion provided on the first end and a second bulbous portion provided on the second end of each C-shaped member, the first and second bulbous portions of the third C-shaped member are each configured to be in contact with and secured against the first and second bulbous portions of the first and second C-shaped members such that the first, second and third C-shaped members are held together independently.

A bag toss game platform easy to assemble and store is disclosed. Traditional bag toss game platforms are two pre-assembled boxes taking up to 48 inches by 24 inches by 15 inches in total and cannot be dissembled by players after use. But the platforms described herein take (for two sets), in certain embodiments, no more than 48 inches by 13 inches by 3.5 inches (i.e., about of the traditional volume) and can easily be assembled for gameplay and disassembled after use. The platform may include a top surface, at least two side supports, and at least two cross bars connecting the at least two side supports. Because cross lap joints between the side supports and cross bars, and groove joints between the top surface and the side supports and cross bars may be used, the platform is easily assembled for use and disassembled for transportation and storage.
