Legal bonus options in the state are limited but worth knowing about. From free virtual credits at social casinos to VIP rewards at bidding sites and trading bonuses at prediction market apps.

If you're curious how these stack up, our casino bonuses cover what you'd typically expect at other sites. Here's a breakdown of what's available to you in WA:

• 

  No deposit bonuses

  Many social casino sites offer free virtual credits just for signing up, with no purchase required. BetRivers.net is one of the best options for Washington players right now. You can claim $1,000 in virtual credits the moment your account is verified, with nothing to spend to get started.

• 

  Match bonuses

  Some platforms boost your balance by matching what you put in. BetRivers.net doubles your virtual credits when you enter code 200MATCH at sign-up. Meaning you start with triple what you'd normally get with a first purchase.

• 

  VIP bonuses

  A handful of sites reward new players with VIP perks straight off the bat. GalaxyBids is a standout for WA players - sign up with code CORGBONUS and unlock VIP benefits.

• 

  Trading bonuses

  Prediction market platforms treat their sign-up incentives as trading bonuses rather than gambling promotions. Kalshi offers a $20 bonus when you deposit $10, giving you extra funds to trade on real-world outcomes.

• 

  Social media giveaways

  No matter where you sign up, make sure to follow your chosen site on social media. Platforms like BetRivers.net and GalaxyBids regularly run giveaways across Facebook, X, and Instagram. You can find contests, polls, and participation rewards that can top up your balance without spending a thing.

While real money online casinos and sweepstakes sites are banned in Washington, you still have more options than you might think. Here's a look at what's currently legal in the state:

• 

  Social casinos

  These free-play sites let you play casino-style games using virtual coins, with no real money prizes or redemptions involved. You get free credits on sign-up and can purchase more to keep playing, but everything stays within the platform. This makes them fully legal in Washington.

  🧠 Expert tip: Because there are no redemptions, social casinos are purely for entertainment. They're a good option if you want real casino-style fun without any financial risk or legal problems.

• 

  Penny auctions

  Live bidding platforms fall outside Washington's gambling statutes entirely, as they're classified differently from traditional gambling. You can bid as little as 1-cent for a chance to win real prizes on sites like GalaxyBids. With everything from Amazon vouchers to Rolexes up for grabs.

  🧠 Expert tip: GalaxyBids is one of the few platforms you can legally compete for real prizes in WA. Use code CORGBONUS at sign-up to unlock VIP benefits.

• 

  Prediction markets

  Platforms like Kalshi allow you to trade on real-world outcomes using Yes/No contracts rather than traditional sportsbook odds. Because these are classified as financial contracts rather than gambling, they operate legally in Washington state.

  🧠 Expert tip: Availability can vary by market type, so always check what's live in Washington before signing up. Our experts track the leading prediction market platforms and update this page as access evolves.

• 

  Sports betting

  Sports betting is legal in Washington under HB 2638, but only on tribal lands. More than 15 tribal casinos across the state now offer in-person sportsbooks. Some offer mobile apps for use on casino grounds. However, you cannot legally place a bet from home.

  🧠 Expert tip: Some casinos partner with major operators like DraftKings, FanDuel, and Caesars. So you may be able to use a familiar app, but only while physically on tribal land.

• 

  Horse racing bets

  Horse racing has been legal in Washington for decades. You can bet in person at Emerald Downs and Sun Downs, or use licensed online platforms like TVG for simulcast races. Your stake goes into a shared pool rather than against the house. This model has always been permitted under Washington law.

  🧠 Expert tip: Parimutuel sites are another option worth watching. Platforms like Horseplay are expected to become more widely available to Washington players in the near future. Our experts are tracking new launches and will update this page as access expands.

• 

  State lottery

  The Washington State Lottery is one of the few legal betting-style options available statewide. All tickets must be purchased in person from authorized retailers, as online ticket sales aren't currently permitted.

  🧠 Expert tip: Washington lottery winnings are subject to federal taxes, so factor that in if you're playing for bigger prizes.
