Each player gets 18 discs of a color and places them face up in front of him. Alternating the players place now the discs on the board. The first disc could be placed entirely free, all further must be placed in the row or the column where the last chip has been placed. If one has a higher sum than the fellow player thereby in a row, then you turns all face up chips of your opponent face down and if your (if there are any) face down chips face up. The game ends if no player could place a new chip according to the rules. The player with the highest face up total wins.
