An Ice Cream Man Hacked a Game Show by Memorizing the "Random" Board

In 1984, Michael Larson was an unemployed ice cream truck driver in Ohio with a VCR and a lot of free time. He spent his afternoons watching Press Your Luck, the CBS game show where contestants pressed a buzzer to stop a "randomly" spinning board.

The Discovery

Larson recorded episodes and played them back frame-by-frame. What he found stunned him: the board wasn't random at all. It cycled through just 5 repeating patterns. Memorize the sequences, and you'd know exactly when to press the buzzer to land on the biggest prizes — and avoid the dreaded Whammys that wiped your total.

He spent weeks drilling the patterns into memory until he could hit them with split-second precision.

The Performance

On June 8, 1984, Larson appeared on the show. He hit 45 consecutive winning spins without landing on a single Whammy. The audience grew stunned. The host grew suspicious. The producers were in disbelief.

He walked away with $110,237 in cash and prizes — the largest single-day haul in game show history at the time.

The Investigation

CBS launched an immediate investigation. But after reviewing the tapes and the rules, they reached an uncomfortable conclusion: Larson hadn't cheated. He'd simply outsmarted them. There was no rule against memorizing the board.

They paid him in full and quietly reprogrammed the board with 27 additional patterns (32 total).

An ice cream man with a VCR had beaten a national television network at its own game — and there wasn't a thing they could do about it.
