The puzzle game is based on a series of pieces made from cubes linked in various configurations that can be assembled to form different shapes or make up a parallelpiped block. The difficulty of the puzzle depends on the number of cubes linked to form each piece and the number of different ways in which they can be assembled, with the more difficult puzzles having five or six linked cubes in each piece. Each puzzle is supplied with suggested shapes that can be made from the pieces, together with a key for assembling them. The player can also make up new shapes.
