Bonk

Your goal? Roll steel balls down your slide in order to knock the 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 slides as it's difficult to roll balls down both slides at once.)

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 with the steel balls remaining on the half of the board where they're currently located. The first team to score five points wins! BONK features the same gameplay as Rollet but the games have important differences that affect play (and their prices): The BONK game board is smaller, so gameplay tends to be faster.

The BONK game board is made from a single piece of curved wood whereas Rollet is made from two; this difference affects the curve of the game board and therefore the movement of the balls. The slides in BONK are plastic whereas Rollet uses wooden slides.
