In a three-dimensional translational puzzle, the cubes (5) maintained in a frame (4) can be moved in three dimensions and brought into different relative spatial positions. The aim of the game is to obtain specific arrangements of the cubes (5). A visible, so-called empty space inside the frame (4) allows the cubes (5) to be moved. The visible empty space can be moved to an invisible internal empty space by means of a mechanism (1), whereupon the puzzle assumes the shape of a symmetrical body. |
