Washington gambling laws

Washington gambling laws in brief

Washington allows gambling in person in specific, licensed or compact-based forms, and bars it online. The Washington State Gambling Commission's online gambling FAQ (opens in a new tab) says state law prohibits any online gambling, and it confirms the felony classification of the internet offense.

Whether you live in Seattle, Spokane or Tacoma, the same statewide rules apply. This page walks through each form of gambling, the statutes behind it, how the commission enforces them and where the gaps in published information are. For the wider picture, start at the Washington online casinos hub.

RCW 9.46.240: Washington's online gambling law

The core rule is RCW 9.46.240 (opens in a new tab). It makes it a class C felony to knowingly transmit or receive gambling information by telephone, the internet or similar means, or to install or maintain equipment for that purpose.

Two parts of the wording matter for readers. First, the statute covers receiving as well as transmitting, so its text is not limited to operators. Second, it carves out activity authorized under chapter 9.46, which is how compact sports wagering at tribal casinos stays lawful.

What the class C felony label means

The statute assigns the penalty through RCW 9A.20.021, Washington's general sentencing provision for felony classes. We don't quote fine or prison figures here because we haven't confirmed them from an official page; read the statute text for the current numbers. We also don't report how often the law has been applied to individual players, because we found no published data on that.

This page explains what the law says. It is not legal advice, and we don't say any reader will be prosecuted. If you need advice on your own situation, speak to a Washington attorney.

Washington State Gambling Commission: the regulator and its powers

The Washington State Gambling Commission (WSGC) is the state regulator for gambling. Its public FAQ is direct: online gambling is prohibited, and the internet offense is a felony.

The commission acts against offshore operators as well as warning the public. On September 19, 2025, it issued a second cease-and-desist notice to Bovada (opens in a new tab), which it described as registered in Curaçao. The notice cited RCW 9.46.0237, RCW 9A.82.045 and RCW 9.46.240. Our Bovada review covers the brand, and the cease-and-desist letters explainer shows how regulators in other states use the same tool.

Tribal casinos and sports betting in Washington

Tribal casinos are the main form of casino gambling in Washington. The commission's records describe them as operating under tribal-state compacts, with some authorized for sports wagering. We haven't confirmed a current count of venues, so we don't give one.

Compacts come from federal law. The Indian Gaming Regulatory Act of 1988 says class III gaming, which includes casino games and slot machines, is lawful only under an approved tribal ordinance and a tribal-state compact in a state that permits such gaming. Our tribal gaming guide explains the three classes.

Sports wagering follows the same path. Since the Supreme Court's 2018 decision in Murphy v. NCAA, states can legalize sports betting; Washington chose to allow it only at authorized tribal casinos, not statewide online. See Washington sports betting for venue and app questions.

Are sweepstakes casinos legal in Washington?

Dual-currency sweepstakes sites use Gold Coins for play and Sweeps Coins that can be redeemed for prizes. A third-party sweepstakes site reports that Washington restricts them under existing law, RCW 9.46.240, and that no new sweepstakes-specific statute has been passed. Treat that as reported.

The brands' own rules point the same way. Several large sweepstakes operators list Washington as a restricted state in their official terms or rules.

Read our Washington sweepstakes casinos page and the national overview of sweepstakes casino bans for the states that have passed specific laws.

How federal law fits with Washington law

Federal statutes mostly target businesses, and they defer to state law on what is lawful. That makes Washington's statute the deciding rule for anyone in the state.

• The Wire Act (18 U.S.C. § 1084) applies to people in the business of betting; the First Circuit held in January 2021 that it covers only sports-related wagering.
• The UIGEA (31 U.S.C. §§ 5361–5367) bars gambling businesses from accepting payments for unlawful internet gambling, defined by the law of the state where the bet is made.
• The Illegal Gambling Business Act (18 U.S.C. § 1955) makes it a federal crime to run a gambling business that breaks state law, with five or more people involved.
• IGRA (25 U.S.C. § 2701 and following) sets the framework for Washington's tribal compacts.

Because the UIGEA defines unlawful gambling by reference to the state where a bet is made, Washington's prohibition carries through to the federal payment rules. Our UIGEA explainer covers the payment side.

Washington and federal gambling law timeline

Recorded dates that shape the law for Washington residents:

On recent Washington bills, we found no new sweepstakes-specific statute and no measure to license online casinos. If that changes, the commission's news page is the first place it will appear.

Gambling ages, the lottery and fantasy sports: what isn't confirmed

We publish only details we can trace to a source. For Washington, the minimum gambling ages, current lottery rules and daily fantasy sports status were not confirmed from the commission's pages at our October 2026 check, so we leave them out rather than guess.

If you need the age for a tribal casino or card room, check with the venue or the WSGC. The national gambling age by state page lists what is confirmed elsewhere, and the daily fantasy sports laws page covers the national picture.

Why we show no casino offers to Washington readers

Our partner casinos are offshore sites, licensed (if at all) outside the US and not licensed by any state. Washington's law makes unauthorized online gambling a felony, so we don't place offers, bonus codes or sign-up links on any Washington page.

There is a second reason for one brand: third-party reviews report that Decode Casino refuses players from Washington. You can still read our independent reviews, such as the SlotoCash review or the Decode review, to see how offshore casinos work and why their terms matter. The Washington real money casinos page covers deposits, withdrawals and taxes from a Washington point of view.
