The legal gambling age in California is either 18 or 21, depending on the activity. You can buy a lottery ticket or bet on a horse race at 18. You have to be 21 to enter a licensed card room. Tribal casinos set their own rules through compacts with the state, and in practice the line is drawn at 21 if alcohol is served on the gaming floor and 18 if it isn’t. Sports betting is not legal in California at any age, and there are no licensed online casinos.
Gambling Ages by Activity
- California State Lottery: 18
- Horse racing and pari-mutuel betting (in person or through licensed online platforms): 18
- Tribal casinos without alcohol on the gaming floor: 18
- Tribal casinos serving alcohol on the gaming floor: 21
- Licensed card rooms: 21
- Charitable bingo: 18, with minors prohibited from playing
- Sports betting, in person or online: not legal in California
- Online casinos: not legal in California
The split comes from different sources of law. The State Lottery Act sets 18 for lottery play. The California Horse Racing Board’s regulations set 18 for pari-mutuel wagering. The Gambling Control Act in the Business and Professions Code sets 21 for card rooms. Tribal casino ages come from each tribe’s compact with the state.
Tribal Casinos: 18 or 21
California has more tribal casinos than any other state, and the minimum age is not uniform across them. Tribes operate under the federal Indian Gaming Regulatory Act, which allows Class III gaming such as slot machines, blackjack, roulette, and baccarat through compacts negotiated with the state. Each compact can set its own minimum age, but the practical dividing line is alcohol. Casinos that serve alcohol on the gaming floor set the age at 21. Those that don’t can admit players as young as 18.
Call the specific casino before you drive out. A property forty-five minutes away may admit 18-year-olds while the one closer to home will not, and the policy can turn on whether a bar sits inside or outside the gaming area.
Card Rooms Are 21 and Over, No Exceptions
Licensed card rooms are strictly 21-and-over regardless of whether the room itself serves alcohol. A person under 21 is not permitted to enter the gambling area at all. Card rooms are limited to player-dealt card games such as Texas Hold’em, other poker variants, and Pai Gow Poker; the house takes a seat rental or per-hand fee rather than banking the game. Slot machines, roulette, and dice games are not permitted in a card room.
Working at a card room follows the same age rule. Employees need a valid work permit and must be at least 21. Workers aged 18 to 20 can hold non-gaming positions only. They cannot supervise gambling, perform gambling-related duties, or enter the gambling area, and they must wear a visible badge reading “Non-Gaming Employee: Under 21” at all times.
Lottery at 18
Anyone 18 or older can play the California State Lottery, which covers Powerball, Mega Millions, SuperLotto Plus, Fantasy 5, daily draw games, and Scratchers. California Government Code Section 8880.52 makes it a misdemeanor to sell a lottery ticket to someone under 18, and it is also a misdemeanor for a minor to buy one. No prize will be paid to a winner under 18, even if the ticket is a winner.
Claim windows are tight. Draw game winners have 180 days from the draw date to claim. Mega Millions and Powerball jackpot winners get a full year. Scratchers winners have 180 days from the game’s announced end date. Miss the deadline and the prize is forfeited.
One financial point matters even at 18: California does not tax California Lottery winnings at the state level, including SuperLotto, Powerball, and Mega Millions. Federal tax still applies. The exemption does not extend to casino, card room, or horse racing winnings, which do get taxed on your California return.
Horse Racing at 18, Including Online
You can bet on horse races in California at 18. The age was set by the California Horse Racing Board rather than by statute, and it applies to pari-mutuel wagering at tracks including Santa Anita Park, Del Mar, and Los Alamitos.
If you prefer to bet from your phone, California licenses several advance deposit wagering platforms, including TVG, TwinSpires, Xpressbet, and WatchandWager. Account registration requires you to be at least 18, and advertisements for these platforms must state that minors cannot open or access accounts. This is the only form of legal online gambling in the state.
Bingo, Raffles, and Private Poker Games
Charitable bingo is governed by Penal Code Section 326.5. Minors are prohibited from playing, the game must be open to the general public, and players must be physically present where the game is held.
Nonprofit raffles follow a separate framework. Only tax-exempt nonprofits that have been qualified to do business in California for at least a year may conduct raffles, and a person 18 or older must supervise each raffle. Most organizations have to register with the Attorney General’s Registry of Charities and Fundraisers and receive written confirmation before selling tickets; religious organizations, schools, and hospitals are exempt from registration but still have to follow the other rules.
A home poker game is legal in California as long as no one profits from running the game. The Penal Code excludes card games played in a private home or residence from the definition of a controlled game, provided no person makes money for operating the game except as a player. Charge a rake or a house fee and the game becomes illegal gambling. No minimum age is specified in the statute for private social play because it sits outside the regulatory scheme, but parents are responsible for what happens in their own households.
What No One Can Legally Do in California
Sports betting is not legal in California at any age, whether in person at a casino or racetrack or through an online book. Proposition 26 (in-person at tribal casinos and racetracks) and Proposition 27 (online and mobile) were both defeated by wide margins in November 2022. Efforts to put sports betting on the 2024 ballot failed to gain tribal support, and no initiative is expected to reach voters before 2026 at the earliest. As of January 1, 2026, California also banned online sweepstakes and social sportsbook-style platforms that used dual-currency models to award cash prizes.
California likewise has no licensed online casinos. Playing slots, blackjack, or roulette on a website or app from inside the state is not legal, regardless of your age.
Penalties for Underage Gambling
California treats underage gambling as a criminal matter. Under the Penal Code, a venue owner or operator who knowingly lets someone under the required age play commits a misdemeanor. A minor who buys a lottery ticket commits a separate misdemeanor under the Government Code.
Card rooms carry an added rule. A person under 21 who presents false, fraudulent, or borrowed identification to enter a gambling establishment faces separate legal consequences. The establishment itself has a defense only if it can show it demanded proper identification, was shown a bona fide government-issued document, and acted in reliance on it.
Beyond criminal penalties, the California Gambling Control Commission can suspend or revoke a card room’s license for regulatory violations, including failure to enforce age limits, and the Bureau of Gambling Control in the Department of Justice conducts investigations and audits. A pattern of admitting underage patrons can produce both a criminal case against the operator and administrative action against the license.
What ID to Bring
Expect to show identification at any card room or tribal casino with an age requirement. The accepted standard is a document issued by a federal, state, county, or municipal government that includes your name, date of birth, physical description, and photograph. A driver’s license or state ID card is the most common, with a military ID or valid passport also accepted. Lottery retailers and horse racing venues enforcing the 18-and-over rule use the same general principle, and advance deposit wagering platforms verify age during account registration.
