Sports Betting in Washington State – Legal Updates, Sportsbooks & More

Washington state is one of the latest in the U.S. to allow legal sports betting. However, the laws can be a little confusing and options are a little limited.

That’s why, if you’re looking to get in on the online action, you will have a much better betting experience going through sports gambling sites that operate offshore, which is where this guide to sports betting in Washington State comes in.

Best Washington Sports Betting Sites in 2024

Our experts have put in the time to thoroughly research the growing market of online betting sites to find the best ones for you, based on a set of criteria. We have included our top 10 list of the best sportsbooks available to anyone in Washington today. Below is the complete list of the best active sportsbooks available in Washington:

  1. BookMaker – Earliest lines in the market
  2. Heritage Sports – Elite for live betting
  3. Bovada – Great prop builder
  4. BetOnline – Specializes in opinionated lines
  5. BetAnySports – Best for reduced juice (-105)

For more on the legal issues surrounding Washington sports betting and specific betting site features, scroll below in our guide.

Is it legal to bet on sports in Washington?

Sports betting is legal in Washington, but only if done at a tribal casino in the state. However, if you plan on betting on the Washington Huskies, Gonzaga Bulldogs or another in-state collegiate team this year, you’re also out of luck. The Washington State Gambling Commission still prohibits college sports betting.

Strangely, Washington is also one of the few states left in the country where you cannot legally play daily fantasy sports (DFS) with the use of DraftKings or FanDuel.

Until online sports betting is fully functional across the state, your best option is to join one of the best offshore sportsbooks available.

The Best Washington Sportsbooks Reviews 

We understand you need more convincing than a bulleted top 10 list. That is why we have included 10 in-depth reviews for our top offshore sportsbooks that Washington users can join today. 

1. BookMaker: Earliest Lines in the Market

BookMaker is considered one of the top offshore sportsbooks to use in Washington for several reasons.

Additionally, BookMaker features a comprehensive online casino, allowing users to enjoy a diverse range of casino games alongside their sports betting activities. This creates a one-stop platform for all gambling enthusiasts.

Furthermore, BookMaker stands out for its early NFL lines. This means that users can access and place bets on NFL games well in advance before they take place. This gives sharp bettors a significant advantage, allowing them to capitalize on favorable odds and plan their betting strategies accordingly.

Bovada Sportsbook Homepage

Bovada is widely regarded as one of the top offshore sportsbooks to use in Washington. With its reputation for reliability and trustworthiness, Bovada is an excellent option. There is a wide range of enticing promo codes at Bovada for new and existing customers as well. These bonuses include a generous welcome bonus, refer-a-friend bonus and special promotions for specific sports events. Additionally, Bovada’s online casino provides a diverse selection of games and the busiest poker room in the U.S., ensuring there’s something for every gambler’s taste.

  • You’ll wait a long time for checks as a withdrawal method

4. BetOnline: Best Opinionated Lines

BetOnline Homepage

Costa Rica is clearly the offshore sportsbook mecca of the world as BetOnline is another one of its A+ rated sites. The distinguishing factor for BetOnline is opinionated lines on NFL, NBA and MLB. You won’t find these lines elsewhere and you can build props using them.

For example, U.S. sites like FanDuel offer alternate lines for all starting NFL receivers to have 25-plus receiving yards, 40-plus receiving yards and other multiples of 10. But at BetOnline, you can get one receiver with lines like 34-plus yards, 44-plus yards, 54-plus yards and another player in the same game can have options like 28-plus yards, 38-plus yards and so on. It’s just more flexibility for your bets.

You can also get a daily booster for enhanced odds on select markets and there are many options for live betting. The 50% welcome bonus of up to $1,000 is one of the most generous for new users looking to bet on sports. There is also some great promo codes at BetOnline that bettors can use. BetOnline also does a high-quality job with its racebook, esports and a great online casino.


  • Very generous bonuses
  • The fastest payouts
  • Nearly three decades in the business
  • Opinionated lines you won’t get elsewhere


  • Some deposit methods are ineligible for bonuses
  • High fees on credit card deposits

5. BetAnySports: Reduced Juice & More  

BetAnySports Homepage

Also based in Costa Rica since 2002, BetAnySports is an A-rated sportsbook with the best Less Juice Package in our top five. While every site has -110 betting lines and a few more offer reduced juice lines at -108, BetAnySports takes it even further with -105 lines on sides and totals.

You also get access to a pretty solid prop builder that will parlay certain markets you couldn’t even parlay at a retail sportsbook in a Washington casino. BetAnySports is also home to a variety of different lines from American Lines to Offshore Lines to Premier Lines, Super Lines and Ultimate Lines. The differences come in which markets are available, some slight variations in prices and the Super Lines and Premier Lines are mostly about live betting markets.

New accounts can receive a 25% cash bonus of up to $500 on their first deposit. The user is allowed to get one free payout every 30 days and your every seventh deposit is free if you have a “House Money” account. In addition to BetAnySports’ top-quality sports betting options, this online sportsbook also features an all-around casino experience with numerous online casino games available.


  • The most reduced juice (-105) of any site on our list
  • A prop builder that rivals Bovada for the best
  • Can play the state lottery drawings too with 80% better payouts
  • Great customer service options


  • Super Lines are not available for popular football markets
  • Bonus money not eligible on prop bets

6. BetUS: America’s Favorite Sportsbook 

BetUS homepage

BetUS is a very experienced sportsbook from Costa Rica with a launch date of 1994. Known as “America’s Favorite Sportsbook,” BetUS has betting markets on all the popular American leagues as well as plenty of obscure ones like snooker, table tennis and handball. You can also bet on entertainment, political and novelty markets.

The prop picks could be a little better organized like the sites in our top five, but a fair selection is available for popular leagues. The real strengths at BetUS are the high limits, large bonuses and the original content that will help you become a better bettor. Not only are there useful guides about all aspects of betting, but BetUS TV has an original series with experts providing analysis and sports picks. Look for more companies to follow suit as the legal betting industry continues to expand across the states.


  • Deep sportsbook and non-sports markets too
  • Original programming provides expert analysis
  • Multiple guides to help you get better at all facets of gambling
  • Some of the highest limits ($50,000 in crypto)
  • Some of the largest bonuses


  • Props could be better designed
  • Not as many transaction methods as Bovada and rivals

7. WagerWeb: Crypto-Friendly

WagerWeb Homepage

WagerWeb compares most favorably to Heritage Sports when it comes to our top 10 list. Both are from Costa Rica, but WagerWeb has actually been around longer, launching in 1994 compared to 2001 for Heritage Sports. They both also offer -108 reduced juice odds and you can find live betting, a racebook and online casino games. WagerWeb also allows users to join a weekly football contest at no charge.

A lot of the best welcome bonuses at WagerWeb are only eligible to users who make their first deposits using Bitcoin or MoneyGram, so they lose some points for transaction flexibility there. But players not using those methods can get 20% cash up to $1,000 with 10x rollover, so there are promotions for everyone at WagerWeb. You also can receive 1% cash back every Monday for your bets in the sportsbook (win or lose). This will be rewarded as a Free Play with no rollover.


  • Reduced juice (-108) on sports lines
  • Credit card deposits have no fee unlike most rivals
  • Good for crypto users
  • Free weekly football contest


  • Needs to raise limits for non-NFL leagues like NBA and MLB
  • Some strict limitations on sports parlays

8. Everygame: Great Mobile Site

Everygame Sportsbook Homepage

Long known as Intertops, the Antigua-based Everygame was rebranded recently to celebrate its 25th year in the business. With a sleek, new web design and deep sports markets, the rebranding is a very accurate name for this A-rated site. You also get a great selection of obscure sports and you can even bet on markets like the South African Powerball drawing.

There is a robust live betting section with markets on college football, American football, soccer and many more. You also get access to a couple of the best online casinos around with over 300 video slots and a downloadable app for online poker is also available.

New users can get up to $750 on their first three deposits as a sign-up bonus. You will get $250 per deposit with 4x rollover (minimum odds of -200) that must be completed before the next bonus is unlocked. Users can also take advantage of an Everygame promo code in order to unlock exclusive benefits.


  • Hottest bets show you which bets are trending
  • Live betting was a big addition
  • The best-looking site on our list
  • Arguably the best casino on our list


  • High rollover requirements to unlock bonuses
  • Needs more customer service methods

9. SportsBetting: 50% Sports Welcome Bonus 

Sportsbetting Homepage

SportsBetting may not have put a lot of thought into its name, but its website is impressive. It was bought years ago by BetOnline, so you can see some similarities in how the sites look and operate, which is good since BetOnline is one of our top choices.

But SportsBetting is a bit more than just a copycat of BetOnline. SportsBetting also offers some very generous promotions, including a 50% Sports Welcome Bonus of up to $1,000. There are also 25% sports reload bonuses up to $250 and 35% when you use crypto.

You can also enter great sports contests like NFL Survivor pools where the winners can take anywhere from $10,000 (free entry) to $150,000 ($30 entry fee). You can also get some fun insurance on your bets like a $50 credit on spread bets if the NFL team you bet on gets shut out or a $50 credit on NBA moneyline bets if your team blows a 15-point lead after halftime. Your first live bet is also a $25 risk-free bet, so give in-game betting a try when you join SportsBetting.


  • A vast selection of fun and unique promotions
  • Very similar experience to BetOnline
  • Plenty of sports contests to enter (free and paid) with big prizes
  • A huge range of deposit methods


  • Sportsbook menu showing markets could be better designed
  • Reduced juice is only for NHL markets

10. JustBet: A Sister Site to BookMaker

JustBet Sportsbook Homepage

JustBet is a sister site to BookMaker, our No. 1 sportsbook. The good news is you can expect a similar gambling experience that you would get at BookMaker, including the early lines on sports that they are famous for. You will also have access to a racebook section and a casino loaded with your usual assortment of Vegas-style games. The loyalty program is also very much the same thing with three tiers (Gold, Platinum, Diamond) where you accumulate points for rewards such as great reload bonuses.

If there is a criticism we can put on JustBet, it would be that it doesn’t distinguish itself enough from BookMaker. They could have added something new that BookMaker does not have like poker tournaments, but you are largely signing up for the same experience on a site that arguably has a worse design than BookMaker’s efficient layout.


  • BookMaker’s sister site adds to reputation
  • Can count on early betting lines
  • $500 cash welcome bonus
  • Some of the best customer service


  • Some aspects of the design are dated
  • Withdrawal checks carry a high $55 fee
  • Doesn’t expand on anything BookMaker already does

History of Gambling in Washington State 

The history of gambling in Washington is a contentious one. Let this following timeline of historical events serve as a guide for the struggle to get any form of gambling legalized in the Evergreen State:

  • September 2021: The state’s first sportsbook opens at Snoqualmie Casino for in-person bets before later adding online bets to those using an app on tribal ground.
  • 2020: Washington state Governor signs a bill that legalizes sports betting in the state, allowing for in-person betting at tribal casinos only.
  • 2018: United States Supreme Court overturns federal ban on sports betting, giving states the option to legalize and regulate sports betting.
  • 2006: Washington state legislature passes a bill that criminalizes online gambling and imposes harsh penalties for those caught participating in it.
  • 2005: Washington State Gambling Commission begins enforcing a ban on all forms of online gambling, including sports betting.
  • 1973: Washington State Gambling Commission is established to regulate all forms of gambling in the state.
  • 1933: Washington State Legislature legalizes pari-mutuel betting on horse racing, which remains the only form of legal sports betting until 2020.
  • 1910: Washington State Legislature outlaws all forms of gambling in the state.

Presently, there is still no law in place to legalize online sports betting across Washington State. The tribal casinos continue to make partnerships with retail sportsbooks such as BetMGM and FanDuel to provide betting options on professional sports in their casinos on tribal grounds.

Washington Sports Betting Teams 

Washington has had a solid sports history, both with professional teams and some top-notch college programs such as Gonzaga (Bulldogs) and the University of Washington (Huskies). With the recent addition of the Seattle Kraken in the NHL, Seattle has had a team in all four major American sports leagues, but never at the same time. The Supersonics left for Oklahoma City in 2008.

Here are some of the most noteworthy professional and college sports teams in Washington State:

  • NFL: Seattle Seahawks
  • NBA: Washington Wizards
  • WNBA: Seattle Storm
  • MLB: Seattle Mariners
  • NHL: Seattle Kraken
  • MLS: Seattle Sounders FC
  • College: Gonzaga University, Seattle University, University of Washington and Washington State University

Washington has a solid selection of teams for all of the fan-favorite sports betting markets, allowing for numerous different betting opportunities for sports fans throughout the state.

Important Traits of the Best Washington Sportsbooks 

The best sportsbooks for bettors in the Evergreen State tend to grade well in the key criteria we use to evaluate them:

A Wide Range of Betting Options

Many moons ago, a sports bettor would call their bookie and just place a spread, total or moneyline wager. Things have changed drastically over time with so many unique betting markets and parlay bets now available. When you join an online betting site, you want to look for a huge selection of game props, player props, futures, in-game betting markets and much more. Same Game Parlays (SGP) are also extremely popular now where you can add multiple props and lines from the same game onto the same parlay. Look for all the sportsbooks to get better at adding those to live up to the high standard FanDuel has set with SGP and SGP+.

A Range of Sports Betting Markets

The top online sportsbooks will allow you to bet on a wide range of sports betting markets and not just the major leagues. You should expect to find NBA, MLB, NHL and NFL betting markets, but there should also be a nice variety of niche sports betting markets and international leagues, such as snooker, rugby and darts.

Competitive Betting Odds 

If you want to get serious about sports betting, you should have accounts at multiple sportsbooks so you can shop around for the best prices on your desired wagers. Some sites, such as Heritage Sports and BetAnySports, offer reduced juice where you can get -108 or even -105 lines instead of the traditional -110 offerings.

Bonuses and Promotions 

A generous sign-up bonus can reel in a new Washington user to a site but keeping them there for the long term is going to require more promotions and perks. In this competitive market, you can expect to see a variety of these offerings at a top-level offshore sportsbook:

  • Reload bonuses 
  • Risk-free bets
  • Rebates on losses
  • Loyalty/VIP membership
  • Refer-a-friend program
  • Enhanced odds 
  • Contests/sweepstakes

Always check for these on a continuous basis, including limited deals that may require the use of sportsbook promo codes like the ones we track at Bookmakers Review. 

Mobile-Friendly Interface to Make Bets 

The beauty of online sports betting is being able to use your phone to make bets on the fly. This is why we love to see a mobile betting site that looks good on a phone or tablet, runs smoothly and can handle live bets in an instant for as many markets as possible. Most of the offshore betting sites lack a native app that you can download on the Play Store or Apple Store, but they all have websites tested to run well on your favorite devices.

Trustworthy Reputation 

Experience does count for something, so companies such as BookMaker and BetOnline that can boast 25-plus years of experience are given a boost for reliability and trustworthiness. A lot of new sites will be popping up in this market as more parts of the U.S. and the world legalize online sports gambling, but BMR will always be on top of reviewing these sites to find the best brands for you to join.

Accepted Banking Methods

Experienced bettors know to look for online sportsbooks that offer multiple different banking options, including credit cards (Mastercard, Visa, American Express), debit cards, bank wire transfers, e-wallets and even cryptocurrency options (Bitcoin, Bitcoin Cash, Ethereum).

Crypto deposits and withdrawals will often come with bonuses and will not have any fees associated with using them at many online sportsbooks.

Quick and Secure Sportsbook Payouts 

One of the easiest ways to get a bad grade is to have a bad reputation when it comes to paying customers in a timely manner. We put a lot of importance on a site’s ability to pay winning bets on time and with a wide selection of withdrawal and deposit options.

Fortunately, most online sportsbooks are getting good at providing a variety of payment methods from traditional services (credit/debit cards, checks, wire transfers) to more modern methods (P2P, eWallets, cryptocurrencies like Bitcoin, etc.). 

Helpful Customer Service 

Bet on sports often enough and the day may come when you have a need to dispute the way a sports bet was settled. Maybe because a player was injured or a surprise scratch before game time. You should be able to inquire about this or any other issue with a variety of customer service methods, including online forms, emails, phone calls and video chat. Most do offer this support 24/7, but some sites are inevitably going to be more helpful than others with their customer service team.

What are the differences between Washington-regulated sportsbooks and offshore sportsbooks?

A regulated sportsbook in Washington would be one that has to follow all the rules and regulations set forth by the state to legally operate within state lines. If a sportsbook is offshore, then it is located in another country and only has to follow the rules in its jurisdiction. This is why offshore betting sites and offshore mobile sportsbooks are allowed to accept Washington users even if they can only access in-person sports betting locally.

This does not mean the online betting sites are breaking any laws, because they do not have to follow the laws of any U.S. territory. Offshore sites like the ones in our guide are all legitimate companies. Users still must be at least 18 years old to join them.

One of the other key differences between regulated sportsbooks and offshore sports betting sites is the fact that offshore sites offer a wide selection of different gambling markets. Their sports betting markets are broader and more varied and you can enjoy casino gambling and online wagering on niche betting markets with them. Regulated legal sportsbooks simply can’t compete with the number of gambling options that you can find with offshore sportsbooks.

FAQs – Online Sports Betting in Washington

Is sports betting legal in Washington?

Tribal casinos are the only physical sportsbook locations in the state.

What gambling is legal in Washington State?

Does Washington allow online sports betting?

Online sports betting is prohibited at this time in the state of Washington. The only state-sanctioned exception to the law is if you place an online sports bet while on tribal lands.

With the tribal casinos starting to make deals with retail sportsbooks (BetMGM, FanDuel, DraftKings, etc.), hopefully, it will be only a matter of time before online sports betting is legal across the state both online and at retail locations.
