In 1984 Michael Larson was a contestant on Press Your Luck. Using the stop-motion on his VCR, he noticed that the presumed random patterns of the game board weren’t actually random, and memorized the sequences. He won 45 consecutive spins and earned a total of $110,237 in cash and prizes.
For 18 hours a day, he sat perched in front of the screens, analyzing every spin of the Big Board frame-by-frame, looking for patterns.
After six months of scrupulous examination, Larson realized that the “random” sequences on Press Your Luck’s Big Board weren’t random at all, but rather five looping patterns that would always jump between the same squares. He wrote down these patterns, memorized them, then honed his timing by watching re-runs and hitting “pause” on his VCR remote when he suspected the board would land on a given square.
Most crucially, Larson determined that two squares on the game board, #4 and #8, always contained a combination of cash and an extra spin. Since he’d memorized the patterns, he knew exactly when the board would land on each square
