The players each start with 5 rings on the board. Every time a ring is moved, it leaves a marker behind. Markers are white on one side and black on the other. When markers are jumped over by a ring they must be flipped, so their color is constantly changing. The players must try to form a row of 5 markers with their own color face up. If a player succeeds in doing so, he removes one of his rings as an indication that he has formed such a row. The first player to remove 3 of his rings wins the game. In other words, each row you make brings you closer to victory-but also makes you weaker, because you have one fewer ring to play with. Very tricky!This game is part of project GIPF. - BoardGameGeek
