Each screen (called a floor), has a set of dice of different colours (blue, red, magenta, green, cyan and white). The player shuffles the dice around the play area, using a frame surrounding 4 of the dice at a time. Dice within this frame can be rotated 90° around a central axis, with the ultimate aim of lining up the dice in the correct colour before the time and move limit expired.

Later levels introduce a third dimension of the dice scattered between 2 and 5 floors. Players then have to rearrange the dice both on the floor they are on and between the floors to finish the level. The number of moves and time allowed increase with the subsequent number of floors. Some areas of the floor are blocked off to the frame, so different routes are needed to move the dice.
