A quiet midweek stop at the Palms turned into a six-figure story when a Las Vegas bettor walked away with $513,257.52 off a $275 wager. The win came courtesy of a 10-leg parlay stitched across NBA and NHL action, all placed through a William Hill mobile account while the bettor was on property at the off-Strip resort.
The ticket needed every single leg to cooperate, and they did, turning what started as a modest shot into one of the bigger reported local sportsbook payouts of the season. The casino did not release the bettor’s name, only the bet slip and the bottom-line number.
According to a report provided by the casino to the Las Vegas Review-Journal, the ticket mixed point spreads, totals and puck-line wagers and ultimately cashed for $513,257.52 once all 10 legs came through. The report notes that the wager was placed via the William Hill sportsbook mobile app while the bettor was at the Palms.
The picks that paid
The parlay combined six NBA results with four NHL puck-line legs, and there was no room for error. On the basketball side: Minnesota 124, Portland 121 (see ESPN); Boston 97, Phoenix 81 (see The Washington Post); Oklahoma City 116, Toronto 107 (see Global News); Charlotte 131, Chicago 99 (see CBS Sports); Milwaukee 128, Miami 117 (see CBS Sports); and Dallas 123, Brooklyn 114 (see ESPN).
The hockey side of the ticket was just as unforgiving: Washington 3-1 over Philadelphia (see NHL.com), Tampa Bay 4-2 over Toronto (see The Washington Post), Colorado 4-2 over the Utah Mammoth (see TheSportsLeader) and Dallas 4-1 over Seattle (see NHL.com).
Parlay math and why payouts jump
Parlays link multiple outcomes on a single ticket so a relatively small stake can balloon into a major payout when every selection hits. William Hill’s Nevada house rules spell out how payouts are calculated and how pushes are treated, details that matter a lot once you string together this many legs (see William Hill). Because the odds of each pick are multiplied together, these kinds of tickets almost always die somewhere in the middle, which is why the rare wins stand out and get promoted by casinos and sportsbooks.
Off-Strip backdrop
The winning ticket ran through the Palms, the off-Strip resort that operates a William Hill retail book and leans into mobile betting for Nevada customers. The property’s site describes the William Hill sportsbook and the on-site betting setup, including mobile app access for guests on property (see Palms). The casino’s report on the wager did not identify the customer behind the slip.
Whether the mystery winner was a local grinder or a lucky visitor, the ticket is a sharp reminder of both the upside and the steep odds that come with parlay betting. Local sportsbooks will handle any tax paperwork and reporting through standard procedures, and gamblers are still on the hook to follow Nevada and federal rules on declaring gambling income. Betting pros keep coming back to the same point: parlays are fun to talk about when they hit, but they are still a long shot by design.
