Get the LOWEST score possible! A Gutterball (0 pins) is the perfect shot.
Play like regular bowling
Keep bumpers raised on both sides
Fewest pins = best score
Leave 2+ pins split apart? Roll between them on your next throw without hitting any pins. Succeed and subtract those standing pins from your score!
First ball stuck on the lane? Knock it into the gutter with your second ball. If BOTH balls end up in the gutter (no pins down), you WIN instantly!
