The game is made of 36 wooden cubes in four colors. There is no board: the cubes move on the playing surface, and the space changes as the game goes on.

The rules propose two different games :

IMIN is a movement game in which you must eliminate the cubes of your opponents on an horizontal ever changing 2D surface.

ASH is a 3D game: in the first phase you must try to form a square of four cube horizontally or vertically; if no one wins, then in the second phase you must eliminate the highest number of your opponents' cubes.
