Abstract: A puzzle game includes a game board with a square playing surface, and a plurality of blocks defined by cubes, at least one of the blocks being a single cube and the remaining blocks including two or more cubes defining L-shaped, T-shaped, cruciform and straight blocks. The blocks can be arranged on the board to cover the entire playing surface, or stacked to form a cube, T-shaped walls or sets of stairs. Recesses can be provided in one surface of the blocks for receiving pegs, which increases the number of games which can be played with the puzzle game.
