CIRCULATION is a mind-bending puzzle game. It is based on interlocking rings of different colours. Each ring comprises a set of circles having the same colour as the ring. If the rings are rotated the coloured circles get mixed up between the rings. The challenge to the player is to restore the rings to their original starting configuration by rotating the rings.
Circulation is fascinating and challenging to play; a sort of two dimensional Rubiks Cube. Race against the clock to be the fastest to solve a variety of different configurations.
