A local sports bettor who originally signed up for the William Hill Sportsbook mobile app at Palms Casino Resort turned a $275 wager into a life-changing payday of $513,257.52 after hitting a massive 10-leg parlay.

The winning ticket spanned NBA and NHL matchups with point spreads, totals and puck line selections. With all 10 legs needed to hit for the wager to cash, the final game sealed the win on Feb. 25, turning a $275 bet into more than $500,000.

The six-figure payout highlights the excitement and high-reward potential of multi-leg parlays, where every selection must hit to cash in. In this case, the bettor’s calculated risk delivered spectacular results.

This major mobile win adds to a growing streak of recent big slot and table game payouts at Palms, where Club Serrano members enjoy exclusive benefits, promotions and exciting opportunities to win big.

William Hill is renowned for its expansive betting menu, including prop bets and Same Game Parlays, Super Parlays, live Cash Out and livestreaming of marquee sporting events right in the app.

Sports fans can wager in person at the William Hill Sportsbook inside Palms Casino Resort or through the William Hill Sportsbook mobile app. Visit Palms.com for more information.
