Henry Gribbohm took his kids to a Manchester, New Hampshire carnival and was playing a game called "Tubs of Fun" to win an Xbox Kinect.
He says his practice tries were easy but when he played for real, the balls didn't work the same way. Gribbohm kept trying to win his money back, dropping $300 in just a few minutes.
He then went home and got his $2300 dollar nest egg and lost all of that money too.
"It's not possible that it wasn't rigged," he said.
The operator gave him back $600 and a giant banana. He filed a police report and an investigation is underway.
