CUBE: Discover Your Cleverness is a single player block-moving logic puzzle.
The object is to move a robot from the start point through to the end point in each level. Each level consists of a pat that 'floats' in space. In addition to the obvious risk of falling off the path into space there are other perils including bomb tiles, conveyor belt tiles, obstacles that must be moved out of the way.
Each level is timed. Any remaining seconds in the countdown timer when the level is completed are translated into the player's score in dollars. These can be used to buy items, such as a lantern to get through the dark levels.
The game consists of 50 such levels and can be entirely controlled by the keyboard though moving the mouse while holding down the left button will adjust the observers position while function keys change the viewpoint.
