Henry Gribbohm claims he lost life savings playing a carnival game, kept playing 'double or nothing'

(CNN)  - A New Hampshire man says his trip to the carnival was a horror show where he ended up losing his life savings. He claims he was conned at a carnival game.

Henry Gribbohm says he lost his life savings -- $2600 - on a carnival game and all he has to show for it is a stuffed banana with dreadlocks.

"You're expecting the kids to win a few things, let the kids have a good time, it just didn't turn out that way," said Gribbohm.

Gribbohm says he attended a Manchester carnival run by Fiesta Shows and wanted to win an Xbox Kinect at a game called Tubs of Fun, where contestants toss balls into a tub. When he practiced he says it was easy but something changed when he started playing and the balls kept popping out.

Gribbohm thinks it is impossible the game was not rigged.

Gribbohm says he kept trying to win back his money by going double or nothing. He dropped 300 dollars in just a few minutes, then says he went home to get 2300 dollars more and soon lost all that as well.

Fiesta Shows says the game is run by an independent contractor who's worked for Fiesta for years. It's interviewing the contractor to see what happened.

Gribbohm says he went back the next day to complain, and the man running the game gave him back 600 dollars. Henry split with the banana and the cash, and filed a report with the Manchester Police Department.

Police are investigating to determine if there was any fraud.

Gribbohm is considering a lawsuit.
