Blongo Ball -- also know as Ladder Golf -- is an extremely addictive backyard or driveway game of skill -- similar to horseshoes but different.
It's a lawn or concrete game that is appropriate for all ages.
You toss a Bolo (piece of rope with a golf ball attached at both ends) toward a Ladder (usually made from PVC pipes) with the hope that it will wrap around and cling to one of the individual rungs on the ladder. Which rung of the ladder your bolo clings to ultimately determine your score, or whether your toss simply cancels out your challenger's.
