California gambling laws explained

California gambling laws at a glance

California has one of the largest gambling markets in the country, yet the legal map is narrow. Gambling is lawful when it happens in a tribal casino under a compact, in a licensed cardroom, or through the California Lottery. Almost everything online sits outside that map, and the Legislature and Attorney General tightened the rules further in 2025.

The sections below take each row in turn. For the wider picture of what Californians can play online, go back to the California online casinos hub.

Who enforces California gambling laws?

Oversight is split between two agencies: the California Gambling Control Commission (opens in a new tab) and the Department of Justice's Bureau of Gambling Control, which carries out compliance and enforcement work. The Bureau's enforcement page (opens in a new tab) divides the state into two regions, and its figures give the clearest count of where legal gambling happens.

Neither agency licenses an online casino, so neither offers a complaint route for a dispute with an offshore site. Our overview of state gambling regulators shows how California's split compares with states that do license online play.

Are online casinos legal under California gambling laws?

No. California has no statute that authorizes or licenses real-money online casino games. Only seven states license online casinos today: New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island, as our list of states with legal online casinos explains.

That leaves offshore casinos, which accept players from Los Angeles, San Diego, San Jose and elsewhere without any California license. Federal law adds another layer. The Unlawful Internet Gambling Enforcement Act restricts payments to gambling businesses where the bet is unlawful under the law of the state where it is made, which is why US cards often decline at these sites. UIGEA does not make placing a bet a federal crime for the player, so state law decides.

We don't tell readers that playing offshore is legal for them, and we don't say they'll be prosecuted. What we can say is that no California agency licenses or supervises these casinos, so there's no state protection of your balance and no state complaint route. Our explainer on offshore casino legality and the California real money casinos page go further.

Tribal casinos and the federal Indian Gaming Regulatory Act

California's 60 tribal casinos operate under the federal Indian Gaming Regulatory Act, passed by Congress on October 17, 1988. IGRA sorts gaming into three classes. Class I covers social and traditional games; Class II covers bingo and certain non-banked card games; Class III covers everything else, including slot machines and banked games such as blackjack.

Class III gaming is lawful only with an approved tribal ordinance, in a state that permits such gaming, and under a tribal-state compact in effect. That compact system is why slots and house-banked table games in California are found on tribal land rather than in commercial resorts. Our pages on tribal gaming and the Indian Gaming Regulatory Act cover the classes in more depth.

California cardrooms

The 91 cardrooms are California's other in-person option, covered by the Bureau's two regional compliance and enforcement sections: 65 in the north and 26 in the south. They sit under state oversight, separate from the federal compact system that governs tribal casinos, and the Commission is the state body listed alongside the Bureau as their regulator. Our cardrooms guide explains how they work for players.

Penal Code 337a and the 2025 daily fantasy opinion

Penal Code 337a deals with wagering on sporting events and contests, and in 2025 it became the basis for a major ruling on paid fantasy contests. In Opinion No. 23-1001 (opens in a new tab), dated July 3, 2025, the Attorney General concluded that daily fantasy sports constitute wagering on sports in violation of section 337a.

The opinion matters beyond fantasy sports for one reason: it says the prohibition applies to contests offered to people in California regardless of where the operators or their technology are located. An attorney general's opinion is not a court ruling, but it shows how the state's top law officer reads the statute against out-of-state platforms. See our daily fantasy sports laws page for the national picture.

California sweepstakes casino law: AB 831

AB 831 is the newest major change to California gambling laws. Trade press reports that the Assembly passed it 79-0 on September 12, 2025, and that Gov. Gavin Newsom signed it on October 11, 2025, with effect from January 1, 2026. The bill page (opens in a new tab) is titled "Gambling: operation of a contest or sweepstakes."

As reported, the law makes it illegal to knowingly and willfully run, promote or facilitate dual-currency sweepstakes casinos, the sites that sell Gold Coins and hand out redeemable Sweeps Coins. It reaches payment processors, geolocation providers and affiliates and carries criminal penalties. Whether players themselves face penalties wasn't found in the reporting. Our California sweepstakes casinos page tracks which brands left, and the national list of sweepstakes casino bans shows the other states that acted.

Sports betting, the lottery and gambling ages in California

Sports betting is not legal in California, either online or at tribal casinos, and third-party trackers recorded the relevant bills as inactive in 2026, with 2028 seen as the next realistic window. Our California sports betting page follows those proposals.

The California Lottery is legal and sets its minimum age at 18, according to its responsible play page (opens in a new tab). A statewide minimum age for tribal casinos and cardrooms isn't published in the sources we rely on, so check with the venue before you go. For online offers on this site we always state 21+ (18+ where allowed). Our gambling age by state table lists the ages that are published.

Penalties under California and federal gambling law

Most published penalties target operators, not players. The exact state fines and jail terms for each California offense aren't set out in the official sources we rely on, so we haven't quoted figures for Penal Code 337a or AB 831. The federal penalties are clearer, and they too aim at people running gambling businesses.

For the federal statutes in full, see our pages on the Wire Act and the Illegal Gambling Business Act.

Recent California gambling bills and rulings: a timeline

No bill to license online casinos was recorded as moving in 2026. If that changes, the California hub will be updated first.

What California gambling laws mean if you play online

Put together, the rules leave a California resident with in-person options that are clearly legal and online options that are not state-licensed. If you still look at offshore casinos, use these checks before you deposit:

1. Confirm the casino is not claiming a California or US license; none exists for online casinos.
2. Find the license it does claim, if any, and note whether reviewers dispute it.
3. Read the withdrawal caps, fees and verification rules before the bonus terms.
4. Expect card deposits to be declined by some US issuers under gambling code MCC 7995.
5. Keep records of every deposit and withdrawal for federal tax purposes.
6. Set a budget and a deposit limit first; the house edge means losses are likely over time.

Winnings from any source are federal taxable income; our gambling taxes guide explains the W-2G thresholds and the reported 90% cap on loss deductions from 2026.

Problem gambling help in California

California funds treatment through the CDPH Office of Problem Gambling (opens in a new tab), and the state program lists a text option: SUPPORT to 53342. The National Problem Gambling Helpline, run by NCPG, answers calls and texts 24 hours a day at 1-800-MY-RESET (1-800-697-3738), with chat at ncpgambling.org. Gamblers Anonymous holds in-person and online meetings, and blocking tools such as Gamban and BetBlocker can stop access to gambling sites on your devices.

Offshore casino offers shown to California readers

Because California licenses no online casino, any real-money site a Californian finds is offshore. The two below are offshore casinos that are not licensed by California or any US state; check California law and the points above before deciding, and remember there's no state regulator to help with a dispute. Offers are for new players aged 21+ (18+ where allowed), and terms apply.

• SlotoCash: $6,000 Welcome Bonus + 60 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Its own welcome terms say 25x deposit plus bonus, a $20 minimum deposit per bonus and no max cashout; the casino's site advertises a different five-deposit package, so the terms shown at sign-up apply.
• Decode: $5,000 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Decode's terms couldn't be read on its own site; third-party reviews report 25x to 35x deposit plus bonus and a $25 minimum deposit on its coded offers.

SlotoCash's terms say its bonus play is limited to slots, keno and scratch cards, and table games are usually excluded or weighted lower elsewhere, so check the terms. Read the SlotoCash review and Decode review for the regulator actions, caps and complaints, including the Michigan Gaming Control Board's October 2026 cease-and-desist letter naming SlotoCash. For bonus math, see California online casino bonuses.

21+ (18+ where allowed). Every casino game has a built-in house edge, so over time you should expect to lose what you stake. Set a budget before you play and stop when it’s gone: responsible gambling tools and free help. Gambling problem? Call or text 1-800-MY-RESET (1-800-697-3738).
