Tour Prize Purse: $65,000
Championship: World Series of Beer Pong X, January 1–5, 2015, in Las Vegas
Rules: Fill cups; throw ping-pong balls into your opponents’ cups to make them drink, and then throw away their cup. First team out of cups loses.
Odds: Tournament beer pong’s rule book has a surprising loophole: You don’t have to drink the beer. “Actually, we just use water. We can’t really force people to get drunk,” WSOBP founder Billy Gaines says. “And this blew my mind, but some college kids don’t even use beer anymore. I think that makes them pussies, but, you know.”
