The “board” consists of a series of lanes into which balls are dropped. Flippers spanning two lanes will either hold a ball, if in the upright position, or allow the ball to pass thru, changing the position of the flipper and allowing any held balls to fall.
Each player has ten balls of their own color. Either black or white. Balls passing out the bottom of the board goes to the player of the opposing color. White balls go to the black player and black balls to the white player. The first player to have all ten balls of the opposite color wins.
Their are nine different board layouts that can be played against the computer or another person.
