Online gambling is not legal in Washington state, with two narrow exceptions: you can bet on horse racing through a licensed advance deposit wagering account from home, and you can use a sportsbook app while physically standing inside a tribal casino. Everything else — offshore poker sites, online slots, daily fantasy contests with an entry fee, social casinos that sell chips — falls under a Class C felony statute that punishes players as well as operators.1Washington State Legislature. RCW 9.46.240 – Gambling Information
Why Washington Is Different
Most states that prohibit online gambling aim their laws at operators. Washington aims at everyone in the transaction. RCW 9.46.240 makes it a crime to knowingly transmit or receive gambling information through the internet, phone, or any telecommunications system. That single word, “receives,” pulls the individual player into the statute. Log into an offshore poker room from your living room in Spokane and, on the plain text of the law, you have committed a Class C felony.1Washington State Legislature. RCW 9.46.240 – Gambling Information
The Washington Supreme Court upheld the statute in 2010 against a dormant commerce clause challenge brought by a poker player, holding that the legislature had authority to criminalize the transmission of gambling information over the internet.2Justia. Washington Supreme Court 83040-1 – Lee H. Rousso v State of Washington The statute carves out only narrow exceptions: the state lottery, activities specifically authorized elsewhere in the gambling chapter, and tribal sports wagering under amended compacts.1Washington State Legislature. RCW 9.46.240 – Gambling Information
Horse Racing Is the Only Thing You Can Bet On From Home
Advance deposit wagering on horse racing is the one form of online gambling a Washington resident can legally do from a couch. RCW 67.16.260 authorizes the Washington Horse Racing Commission to license providers that accept horse racing wagers through online accounts. You fund the account in advance and place bets through the provider’s platform.3Washington State Legislature. RCW 67.16.260 – Advance Deposit Wagering
The provider has to hold a Washington license. Regulations require each licensee to post a bond or irrevocable letter of credit protecting account holders, and the commission evaluates whether the provider’s home state has adequate compliance monitoring before approving a license.4Cornell Law Institute. Washington Code 260-49-020 – Requirements to Conduct Authorized Advance Deposit Wagering Betting on horses through an unlicensed platform falls back under the felony ban.
Sports Betting Apps Work Only Inside a Tribal Casino
Governor Inslee signed House Bill 2638 in March 2020, legalizing sports wagering on what the bill itself called “a very limited basis.” The limit is physical: sports bets can only be placed and accepted at a tribe’s gaming facility while the customer is physically present on the premises.5Washington State Legislature. House Bill 2638 – Authorizing Sports Wagering Subject to the Terms of Tribal-State Gaming Compacts
You can use a mobile app, but each tribal facility geofences its property. Step into the parking lot and the app stops taking your bets. As of 2025, twenty-one tribes have signed sports wagering appendices to their compacts, including the Muckleshoot, Snoqualmie, Tulalip, Puyallup, and Spokane tribes. Not all have launched sportsbooks, so availability varies by location.6Washington State Gambling Commission. Sports Wagering Requirements and Rules
Statewide mobile sports betting from home is not authorized, and no serious legislative push to open that up has gained traction.
What About DFS, Social Casinos, and the Lottery Online?
Daily Fantasy Sports
Paid daily fantasy contests are effectively unavailable in Washington. DraftKings, FanDuel, and other major operators do not offer paid contests to Washington residents. No statute names DFS by name, but Washington’s definition of gambling — staking a “thing of value” on a contest with an element of chance — is broad enough to cover a paid entry fee.7Washington State Legislature. Washington Code Chapter 9.46 RCW – Gambling A 2016 bill (HB 2370) would have explicitly classified paid fantasy sports as illegal gambling and made offering them a Class C felony; it did not pass, but the industry treats the state as off-limits.8Washington State Legislature. HB 2370 – Prohibiting Fantasy Sports Games Free-to-play leagues with no entry fee remain legal.
Social Casino Apps
Apps that sell virtual chips for real money are not a loophole. In Kater v. Churchill Downs, the Ninth Circuit held in 2018 that Big Fish Casino’s virtual chips qualify as a “thing of value” under RCW 9.46.0285 because buying chips extends the privilege of continued play, and that the app therefore constitutes illegal gambling under Washington law.9United States Court of Appeals for the Ninth Circuit. Kater v Churchill Downs Inc – 886 F.3d 784 The Washington State Gambling Commission has pointed to that ruling as guidance for how it views virtual casinos, and the same reasoning reaches sweepstakes-style casinos that require purchases to keep playing.10Washington State Gambling Commission. Regarding Virtual Casinos
Lottery Tickets Online
Washington’s Lottery does not sell tickets online or through a mobile app. Per the lottery’s own FAQ, the only legal lottery ticket is one bought at a licensed retail location in Washington.11Washington’s Lottery. About Us – FAQ Any site that claims to sell Washington lottery tickets online is unauthorized.
Federal Law Reinforces the Barrier
Two federal statutes make illegal online gambling harder to access in practice. The Unlawful Internet Gambling Enforcement Act defers to state law: if the bet is illegal where placed, UIGEA requires banks and payment processors to block the transaction.12Office of the Law Revision Counsel. 31 U.S. Code 5362 – Definitions Credit cards, debit cards, and bank transfers are routinely declined when directed at offshore gambling sites from Washington.
The Wire Act, 18 U.S.C. 1084, adds a sports-betting-specific federal offense: anyone in the business of betting who knowingly uses a wire communication to transmit bets or wagering information across state lines faces up to two years in federal prison.13Office of the Law Revision Counsel. 18 USC 1084 – Transmission of Wagering Information It targets operators more than individual bettors, but it keeps Washington’s market sealed off from legal sports betting markets elsewhere.
What You Risk If You Gamble Online Anyway
A violation of RCW 9.46.240 is a Class C felony carrying up to five years in a state correctional institution, a fine of up to $10,000, or both.14Washington State Legislature. RCW 9A.20.021 – Maximum Sentences for Crimes Committed July 1, 1984, and After The statute makes no distinction between a commercial operator and an individual player.1Washington State Legislature. RCW 9.46.240 – Gambling Information
Enforcement against individual players appears rare in practice. The Washington State Gambling Commission runs audits, on-site checks, and undercover investigations, and its criminal enforcement covers internet gambling alongside fraud, money laundering, and bookmaking.15Washington State Gambling Commission. Activities We Regulate The agency’s resources are more likely aimed at operators than at someone placing a few bets from home. The legal exposure is still real, and a felony conviction carries collateral consequences for employment, professional licensing, and housing well beyond the fine.
Taxes on Legal Winnings
Washington has no state income tax, so winnings from a tribal casino sportsbook or a licensed horse racing account are not taxed at the state level. Federal tax still applies. All gambling winnings are taxable income under federal law, and payers issue Form W-2G when winnings hit reporting thresholds — $2,000 or more from bingo, keno, and slot machines for 2026, $600 from horse racing at 300-to-1 odds or better, and $5,000 from sweepstakes or wagering pools, with 24% federal withholding on sports wagering, lottery, and similar winnings above $5,000.16Internal Revenue Service. Internal Revenue Bulletin 2026-1917Internal Revenue Service. Instructions for Forms W-2G and 5754 (01/2026) Smaller winnings still have to be reported. Losses are deductible only up to the amount of winnings, and only if you itemize.
