BONK is a fast-rolling ricochet game that is ideally played with four players. Your goal is to roll small steel balls down your slide in order to knock the larger wooden ball in the central arena into your opponents' goal. Players compete in teams of two, with each team trying to protect one goal between them. (If you play individually, you will likely need to alternate between both slides on your side.)

If you run out of steel balls, then you're at the opponents' mercy until they shoot, which will likely land a steel ball on your side of the board. If you knock the wooden ball into the opponents' goal, you score a point, then the next round begins. The first team to score five points wins!

BONK demands a good eye, timing, and teamwork. It penalizes both fumbling and trigger-happy play. Hilarity is guaranteed for ages 8 to 108.
