Players play cards to occupy coloured fields on a map. A player wins by owning 4 directly adjacent fields horizontally, vertically or diagonally. If no player wins after 20 rounds, the player who owns the largest contiguous area (number of horizontally and vertically related fields) is declared the winner. The game was also released as a 2-player "Mitbringspiel" in a smaller package, with play pieces in black and white only: Just4Fun Colours
