Spectacular Tumble

Spectacular Tumble is a two-player game for the Shibumi set. Play begins with a full pyramid of balls, two of which are black scoring balls and the rest evenly divided between the players' colors. Players Red and White take turns removing balls but they may not remove the scoring balls or leave any empty position in the bottom 4x4 layer of the pyramid. The game ends when there is only a single 4x4 layer of balls; a player scores points when balls of her color are adjacent to the scoring balls.
