Whirly Ball might be the most bizarre game I've ever played.
The game is a combination of basketball and Jai-Alai, played
from an electric bumper car.
The game is a bit expensive. I think it's $100 per hour. 10 people play at a time though, so it's $10 per person. If you get a group of 10, this isn't expensive at all.
Whirly Ball is a blast. You have to play it at least once!
