A former semi-pro football player and cage fighter, Steve Wienecke, , has designed and built the Knokkers. Its a big on ground pool table like gaming platform but instead of billiard balls it uses bowling balls.
The size of table is scaled up 4X its original size, which allows players to stand on it. He built its first playable version in his backyard in Fredericktown, Missouri. The game is played pretty much exactly like standard 8-ball pool, the only real difference is that before your shot you’re allowed to pick up and move the cue ball, though you can’t move your feet once you’ve touched it.
