About Us
You must be 21 or older to gamble in California, and in some cases older or younger limits differ by operator and jurisdiction. Gambling involves risk of loss and is not a way to make money. If gambling is causing harm, call the National Problem Gambling Helpline at 1-800-GAMBLER (1-800-426-2537). California residents can also reach the state's problem-gambling resources, including CalGETS.
Online Casinos California is an independent comparison site for people in California who want to understand online casinos before they choose one. We research operators, compare them side by side, and explain the trade-offs in plain language. This page covers who we write for, how we rank sites, how we earn money, and what we can and can't tell you.
What we do and who we write for
Our readers are adults who already know how slots, blackjack, roulette, baccarat, video poker and live-dealer games work. So we don't teach rules. We compare operators on the things that separate them:
- Game library: slots, jackpots, table games, video poker and live dealers
- Bonuses and promotions, including wagering requirements and caps
- Banking options and how quickly withdrawals are usually processed
- Mobile experience
- Customer support
- Licensing, fair-play claims and overall trustworthiness
The site currently reviews and ranks ten operators: Raging Bull, Magician Bet, Slots of Vegas, Uptown Aces, Card Crush, Zumba Cards, BetUS, Amazon Jackpots, Slots and Casino, and Bets.FM. We name no others.
How we assess and rank casinos
Our ratings are editorial scores. They are not customer-review scores and they don't predict your results. We base them on published information and our own review of each operator's terms. We have not claimed to have deposited, played or withdrawn money on any site, and we don't present advertised payout speeds as tested results.
- Licensing and trust: we look at what regulatory or certification claims an operator makes and encourage you to verify them yourself, since we don't assert licences we haven't confirmed.
- Bonus terms: the headline offer matters less than wagering requirements, game restrictions, time limits and maximum cashout.
- Banking and payout speed: deposit and withdrawal methods, stated limits, fees and identity-verification requirements.
- Game range and mobile play: breadth across categories and how well the site works on a phone.
- Support and responsible gambling tools: contact channels and access to deposit limits and self-exclusion.
Scores run from 8.7 to 10.0 across our current list. A high score still comes with drawbacks, and we try to name at least one for every operator we recommend.
How we make money, and why it doesn't buy rankings
Online Casinos California may earn a commission when you follow a link to an operator and sign up. That is how the site is funded. Commission does not decide position: rankings come from the criteria above, and an operator can't pay to move up. Offers change often, so always read the terms on the operator's own site before you deposit.
California law: what you should know
California's rules on gambling are complicated, and we are not lawyers. In general, the state has not set up a licensing system for online casinos run by California regulators, and many sites that accept California players operate offshore or under other arrangements. Sweepstakes-style sites also use different models from real-money casinos. Laws and enforcement can change, so check current rules and consult a qualified professional if you are unsure about your situation, including any tax questions. You are responsible for making sure that playing is permitted where you are and that you meet the age requirement.
Verification and fund security
Expect identity checks (KYC) before a first withdrawal. Operators commonly ask for government ID and proof of address, and this can delay payouts. Payment availability for US customers varies, so confirm which deposit and withdrawal methods work for a USD account before you fund it.
Play responsibly
- Only use money you can afford to lose. Never gamble to escape stress or to recover losses.
- Set deposit limits and take breaks. Many operators offer limits, time-outs and self-exclusion.
- If it stops being fun, stop and get help: 1-800-GAMBLER, or CalGETS for California residents.
