Each player has 3 red, green, blue and yellow playing pieces, but one player uses the round pieces and the other the square ones. Each field of the board shows one of these 4 colors and the pieces can move only on fields of their color. Object of the game is to capture all opposing pieces and still having 2 or more own pieces on the board. Captures are made by jumping over opposing pieces.
