Each player receives a 5x5 board, on which 24 square tiles in six colors are somehow colorfully distributed, as well as a so-called "pattern mixer". This hides behind a plexiglass housing nine small cubes, which must be shaken neatly. In this way, each player receives a task: 3x3 colors arranged in a very specific way. The task now is to achieve exactly this arrangement at the middle 3x3 squares by moving the tiles on your own game board. The outer ring, which still comprises 20 squares, plays no role and is easily hidden by the slightly milky cover anyway. Of course, the winner is the one who could solve his task first. —user summary
