Washington Online Casinos – Legal in 2024?

There are roughly 30 different tribal casinos across Washington state. They have a variety of table games, or you can sit at a slot machine and play away; tribal casinos in the state also offer legal sports wagering.

But what about online casino gambling? The online gambling laws in Washington state still leave a lot to be desired. Because of that, Washington residents looking to play table games for real money online are best served by online casino sites that operate offshore.

At a great online casino in Washington, you should be able to wager on sports and other markets like horse racing and esports. You should also get to play a wide selection of casino games, and even poker with real players in tournaments and cash games. You should also be treated to great welcome bonuses and beneficial perks for being a loyal customer. Finally, you should always feel that your data is protected, your gaming experience is fun and safe, and you will receive payouts in a timely manner with 24/7 customer service available if needed.

That is the dream scenario for your online casino choice, but not every online betting site out there can deliver on all fronts. Some will not even accept you as a user because of the laws in the Evergreen State. That is why we have prepared this guide to direct you to the best online casinos that you can join as a Washington resident and all of them are reliable and trustworthy offshore sportsbooks.

Best Online Casinos in Washington Reviewed

Before choosing the online casino that best suits your personal preferences, you should know that every site in our top 10 list is based in Costa Rica, Panama or Antigua. This defines them as offshore sportsbooks for all Washington and U.S. residents. This is a positive because it means these sites do not seek to be regulated by the laws of Washington State or any American territory.

They only have to follow the laws in their local jurisdictions, which they do as online gambling has been legal for many years. This is why you can join them even though Washington has not legalized online gambling as of 2022.

Bovada Casino

Bovada is an A+ rated online casino from Costa Rica that is very popular among American users. The versatility at Bovada is what makes it such a great choice. The site is already well known for its sportsbook and props builder as well as running on the highest-trafficked poker network for U.S. players.

But in addition to those great things, you can bet on virtual camel races, live betting on a table tennis game in Poland, play baccarat with a live dealer, or wager on political elections. Bovada is a one-stop shop for gambling, and it comes with fast payouts, quality customer service and one of the juiciest welcome promos in the industry. One of the best things about the Bovada promo code for new users is the rollover is only 25x.


  • Build parlays using excellent prop builder
  • Most popular crypto casino in market
  • Seven types of blackjack available
  • Best virtual racing market (horses, camels, greyhounds, etc.)
  • Poker tournaments on the busiest US poker network

2. BetOnline: Best for Big Bonuses and High Limits

BetOnline Casino

You may not be able to download a native app for BetOnline, but the site looks great and runs even better on mobile devices. The welcome bonus is one of the largest on the list, and you get the fastest payouts with BetOnline. As if that wasn’t enough, the promo codes at BetOnline can be used to gain access to exclusive perks and other benefits.

This A+ rated sportsbook has opinionated lines on popular sports markets like the NFL, MLB, and NBA, as well as a more than solid prop builder. You also get a racebook with higher rebates (4% on standard bets and 9% on exotic wagers) than the competition, and your first horse racing bet is risk-free ($25 value).

The casino selection is huge with plenty of games you won’t see elsewhere. The poker room and tournaments are rivaled only by Bovada. The limits on live dealer games are some of the highest around, so if you want to bet big or small, BetOnline is a great site to join.

Heritage Sports Casino

Outside of lacking the poker tournaments you can find at Bovada and BetOnline, Heritage Sports really does everything at a high level. The esports section is one of the most devoted on the list. There are generous promos, perks like free deposits and a free bet on your birthday along with consistent rebates.

The live betting markets are deep and very active each day, and they accentuate what is already one of the best sportsbooks. The site design is one of the best. The casino games run smoothly, and you can play 3D slots and specialty games (scratchcards) that not every site has.

4. BookMaker: Best for Early Lines 

Bookmaker.eu Casino

Bookmaker.eu is one of Costa Rica’s oldest (established 1996) and most respected sportsbooks. They are “where the line originates” as sharps and other sports bettors looking for value picks feast on some of the earliest lines in the business. 

But BookMaker also does live betting well, in addition to a racebook that offers competitive rebates with other rivals (3% on win/place/show bets and up to 8% on exotic wagers). The casino section is loaded with a fair assortment of table games, baccarat, video poker and the live dealer games have respectable limits. 

Better yet, winners will not have their accounts limited or suspended like the fear you have at some sites. The three-tier loyalty program also makes it easier to keep coming back to BookMaker for all your gambling needs. Diamond Reward Level users can get up to $2,500 on reload bonuses (20% cash deposit bonus with only 5x rollover). New players are automatically enrolled and get a welcome deposit bonus to kick them off.

5. BetUS: Best for Expert Analysis

BetUS homepage

In the business since 1994, BetUS is an ideal site for sports bettors and casino enthusiasts alike. If you want to play blackjack, then BetUS has one of the highest counts of variants on the market. If you just want to bet on sports, then the sportsbook is one of the deepest. You can even bet on novelty markets, such as Mark Zuckerberg’s first MMA opponent. 

Perhaps the way BetUS separates itself the most from competitors is the addition of BetUS TV. You get picks and predictions along with expert analysis on a wide range of original TV series you can watch on the site. There are shows for NFL, NBA, MLB, NCAAF, boxing, Premier League, La Liga, Serie A, NHL, NCAAB and more.

Current promotions at BetUS include 200% crypto bonus (150% sportsbook + 50% casino), 125% sign-up bonus and a 250% casino bonus (match bonus up to $5,000). They also offer contests and a VIP loyalty program.

Types of Washington Casino Bonuses

A reason we listed a top 10 and a top five list of online casinos is that we know it is common for players to join multiple online gambling sites. But unless you are rich, chances are most of your deposits will be going into one or two sites that you like the best.

One of the key factors influencing your decision of which site to use is the types of bonuses and promotions available. The welcome bonus is a good way to draw you in to join, but the long-term value comes from other perks available to existing users. The following sections look at some of the bonuses you can expect to see.

Welcome Bonuses

For sheer value, it is hard to top a large welcome bonus. The most common form you will see is a cash bonus that matches your first deposit amount to a certain percentage, most commonly 100%. Some may only do 50%, and some may go big up to 200%, especially if crypto is the method you use for your first deposit. You also have some sites that offer bonuses on your second and third deposits as well, meaning you could total thousands of dollars in bonus cash very quickly. Just be aware of rollover requirements that will have to be met before those bonus funds can be withdrawn as real money. 

Existing Customer Promotions

Why stop at a first deposit bonus? Customers who keep coming back for more are going to want to see other promotions come their way to reward their loyalty. These can be achieved in a variety of ways. 

One of the most popular is a reload bonus, which is basically a deposit match-up to a certain percentage (usually 20-35%) of what you put in.

You also will find some sites like Heritage Sports that give you every eighth deposit on the house based on the average of your previous seven deposits.

Online betting sites usually have some of the best promotions with cash-back rebates, reduced juice or enhanced odds on select Washington sports betting markets, and even refunds on your bets (up to a limit) when things go terribly wrong like your team gets shut out or blows a big lead.

Some sites will also offer parlay boosts that give you a higher payout for hitting parlays with a lot of legs.

No-Deposit Bonuses

Though less common, no-deposit bonuses can be a nice way to get the most out of your money online. Some offshore gambling sites will give users free money when they register.

For example, there may be promotions where if you wager $100 on a casino in one night, you will get $10 in site credit.

On sportsbooks, there will usually be a chance to get a risk-free bet if you wager a certain amount of money on a game.

Free Spins

Free spins can either be part of your welcome bonus at an online casino, or it can be a special promotion for existing users. You can expect anywhere from 10 to 250 free spins on online slot games. If it’s a sportsbook, then a free bet will be the reward.

Payment Methods Available at Washington Online Casinos

We live in an era with more payment options than ever before, so any good online casino should have a slew of choices for both deposits and withdrawals. They all will have more choices than a land-based casino, but you will have to visit the website to read which site offers which method.

Most casino sites will provide players the payment method options of credit and debit cards, bank or wire transfers, old-fashioned checks, money orders, vouchers/gift cards, and more modern methods such as P2P, eWallets, and various cryptocurrencies. You can even negotiate a cash payout.

Many sites push crypto with better bonuses, higher limits, and no fees because it is the fastest processing method for payment. Sites such as Bovada and BookMaker provide helpful guides for beginners on how to use crypto. Some report that nearly 80% of their users are using crypto now.

Washington Online Casinos Comparison – Payment Methods

When it comes to transactions, the main thing to research on each site is the fee and wait time for the payment method you ultimately choose.

Some fees can get pretty expensive, and the processing times can range anywhere from the same day to up to 15 business days with crypto being the fastest and checks the slowest.

We have included another side-by-side comparison of how our top five online casinos stack up in payment methods and processing time:

Game Availability at Online Casinos in Washington

Capturing the casino experience on a mobile device is surprisingly easier than it sounds. All you need is a site with good-looking graphics, turn up the sound on your phone, and have some fun with what is hopefully a deep library of games.

Most of the popular online casino sites offer a wide variety of table games and online slots.

The selection of table games usually includes baccarat, roulette, blackjack, video poker, and specialty games such as keno, bingo, and scratchcards. There are also live dealer games available at our top online betting sites. With select table games, you can play dealer casino games with other players, so you can emulate the social experience of being at one of Washington’s tribal casinos from the comfort of home.

Rollover Requirements at Washington State Online Casinos

This is important to understand. A rollover requirement must be satisfied by placing bets before you can turn your bonus cash into money that can be withdrawn. For example, let’s say you have received $1,000 in bonus money with a rollover requirement of 20x. Before you can withdraw that $1,000, you must first wager $20,000 on the casino or through the sportsbook depending on what type of bonus you received. The casino bonuses are always higher in rollover requirement than the sportsbook ones. Ideally, a lower rollover requirement is what you want to see to make it more likely that you will be able to withdraw some of that bonus money.
