Last Friday, casino officials confirmed a Thunder Valley Casino Resort guest in California recently won a jackpot worth $549,330 while playing in the resort's newly opened High Limit Slots Room.

Key takeaways

  • A California player won $549,330 on a "Dragon Link" slot in Thunder Valley Casino.
  • The United Auburn Indian Community operates the casino.
  • This is Thunder Valley's latest jackpot, with one gambler winning $1.2 million last year.

The guest won while playing the popular "Dragon Link" slot machine and put down a $5 bet when the jackpot hit. The big payout came right after the casino opened its new high-limit area, meant to draw in high-rollers with bigger prizes and a better gaming space.

A Thunder Valley spokesperson said in a press release the new High Limit Slots Room is a luxurious and private area with more than 270 machines made especially for people who like high-stakes games. The addition is meant to make the overall gaming experience better for guests who want to place bigger bets and play in private.

The room features various Aristocrat Gaming games, known for high progressive payouts and many features. It also has a lot of other titles to choose from.

Thunder Valley continues jackpot streak

The resort had a lot of big wins in the last few months, and Friday's jackpot is just one of many from the past year. Another player won a $250,650 progressive jackpot on the "Buffalo Power Pay" slot machine on Jan. 1. The casino's press release at the time said the customer, not named, started 2025 by winning one of the property's first big payouts of the year.

Last year, on July 30, a player named Allen Kessler won a $1.2 million jackpot on the "Buffalo Power Pay" slot machine, which Aristocrat Gaming also made. That win was one of the biggest payouts ever from a slot machine at the casino.

Thunder Valley Casino Resort, just outside Sacramento, keeps adding new titles for players of all levels. The new High Limit Slots Room is part of the casino's ongoing efforts to improve guest services and give it an edge in the Northern California gaming market.

The United Auburn Indian Community runs the casino, which is still popular for playing games and having fun. It has over 3,400 slot machines, several table games, a poker room, plus a hotel and spa. 

California Stake lawsuit moves to arbitration 

In recent news, a California judge ruled the Boyle v. Sweepstakes Ltd case must move to arbitration before it's resolved.

The initial lawsuit, filed on behalf of plaintiff Dennis Boyle, argued Stake.us used a sweepstakes model to operate in California, even though the state prohibits internet gambling. The plaintiff compared Stake’s operations to sweepstakes cafes, later deemed illegal, and outlined that the operator used this loophole to offer its gambling products.

In response to the case, U.S. District Court Judge James Selna ruled the lawsuit must pass arbitration before discussing the illegality of Stake’s operations.
