The man says he attended the carnival with hopes of winning an XBox Kinect at a game where contestants toss balls into a tub. He says when he practiced it was easy, but when he started playing for real, the balls kept popping out!
The man says he kept trying to win back his money by going double or nothing, and spent $300 in just a few minutes. He then went home to get $2,300 more, and ended up losing it all.
"Because you get caught up in the whole double or nothing - I've got to win my money back," said Henry Gribbohm.
All he ended up winning was a stuffed banana with dreadlocks. The man went back the next day to complain, and the man running the game gave him back $600.
Police say they're investigating to determine if there was any fraud in the game, and the man says he's considering a lawsuit.
