Las Vegas has produced plenty of big win stories, but what’s the most money ever won there on a slot machine? That honor belongs to a 25-year-old software engineer from Los Angeles who spent about $100 before the Megabucks machine delivered $39,713,982.25. That $39.7 million Excalibur payout remains the largest slot machine payout ever, verified by Guinness World Records. The young man, whose name is being withheld for obvious reasons, was in Las Vegas on March 21, 2003 visiting family and to watch college basketball’s March Madness tournament. Megabucks machines require a maximum qualifying wager to chase the top progressive prize. When three Megabucks symbols landed, the Excalibur hotel became the site of the largest slot machine payout in history.
