Sign Up

Signing up for a Thunder Rewards Card is one of the smartest moves if you visit Thunder Valley Casino in California, United States. Membership converts play into immediate perks—everything from free slot play to tiered comps that stack up fast. If you like getting rewarded for the games you already play, the card turns routine visits into real upside.

How the Thunder Rewards Sign-Up Bonus works

New members can claim the Thunder Rewards Sign-Up Bonus, which awards $5 to $500 in free slot play. To qualify, sign up for a Thunder Rewards Card at the Rewards Center and be at least 21 years of age. The offer runs on an ongoing basis, but specific eligibility rules and redemption windows apply, so review the terms and conditions at sign-up.

Loyalty benefits that actually pay off

Thunder Valley’s loyalty program isn’t just a punch card. Members earn comps usable across the resort, plus tiered perks across Preferred, Gold, Platinum, President, and Elite levels. Highlights include:

• 5% back in comps on non-gaming purchases, and tiered benefits that increase with play.
• Ongoing earning on both slots and table games, so your play dollars work harder.

Take note: benefits require a Thunder Rewards Card and are subject to program rules and state restrictions for California, United States residents.
