Let’s dive deeper into the top five sites for online gambling in California. Here’s the rundown of how we came to these decisions.
1. Ignition – Our Favorite California Online Casino for May 2025
- License: Anjouan Gaming License
- Payout methods: Visa, Mastercard, Bitcoin, Bitcoin Cash, Litecoin, Ethereum, Tether, Matchpay
- Withdrawal time: 24-48 hours, cards may take longer
- Number of games: 250+

The best place to play casino games in California is, most certainly, Ignition. And there are a lot of significant reasons for that.
First of all, this site hosts some of the best games. It offers slots from hit providers like Betsoft, so you’re going to get some of the most immersive action on the reels, as well.
But the live games here are second to none. We found live blackjack, roulette, and classic table games more from the likes of Visionary iGaming, so you’re going to be in very safe hands.
And that’s not even mentioning poker. The live poker rooms at Ignition are some of the best in California and nationwide, thanks to constant tournaments, high-traffic tables, free rolls, and a feature-rich app.
Plus, newbies still get one of the best welcome bonuses in California right now. Ignition is offering all new crypto players the chance to get up to a $3,000 bonus, which is evenly split between poker and casino action.
Don’t worry if you’d rather pay using a credit card, though. As a new player, you can still get 100% up to $1000 twice over.

If you want to play online slots in California, Slots of Vegas is going to be the best option for you.

Games like Great Golden Lion show off RealTime Gaming’s brilliance — Slots of Vegas is packed with top-tier slots that truly raise the bar for online play!

Outside of slots, there’s still a lot going on here to keep you entertained. Slots of Vegas is home to a robust curation of online poker, blackjack, and roulette games, even if it doesn’t have as many options as some of the sites we’ve listed. But the key here is quality over quantity.

Next on our list of the best online gambling California sites is Super Slots, a platform that’s gained popularity for its live dealer offerings.
The choice of over 70 live casino games is one that beats just about all other California casinos online. The fact that Super Slots is offering live blackjack games with RTPs of 99.5% just shows the high payout potential on offer at this casino.
Since they’ve curated an excellent selection of options from top providers like Fresh Deck Studios and Visionary iGaming, you’ll find all the best blackjack, roulette, and more classic table games here. There are even lottery games, poker, and game shows.
We found the RTPs to be consistently high throughout these games. The live blackjack tables are particularly impressive for high average payouts, but there’s still good value in most of the other games.
The banking setup here is also impressive. Players can choose from over 20 deposit method options, and when payout time comes around, you’ll only need to wait a few hours for processing. Add a $6,000 welcome bonus into the mix, and it’s easy to see why this is one of the best online gambling sites California has to offer.

Raging Bull Slots is offering what our experts have found to be the best casino welcome bonus in California right now. It’s a 250% up to $2,500 deposit bonus that also comes with 50 free spins.
Sure, there are larger welcome bonuses in California, but what really stands out about this one is the wagering requirements. They’re only 10x, making it very easy for you to cash out your winnings compared to most other online casino sites in California.
There’s plenty more to get your hands on after you’re finished with the welcome offer here as well. Raging Bull Slots has all kinds of promo codes to get you extra free spins and deposit matches, and there’s the chance to get cashback every single week.
It’s hard to say how Raging Bull Slots manages to get away with offering so many bonuses with low wagering requirements. But we’re happy to take advantage of it!
You can enjoy some great games with your welcome bonus and reload bonus cash as well. Like Slots of Vegas, Raging Bull Slots has a slot game selection supplied exclusively by RealTime Gaming. Plus, there’s a good selection of poker, blackjack, live games, and more to find here.

- Withdrawal time: Within 24 hours
- Number of games: 1000+
- Bonus: 100 no strings bonus spins
We tested many mobile casinos and found that the best of these was BetOnline. This is based on general usability, thanks to some top-tier site design and high compatibility, in that most of the games can be played on the mobile site.
The games available on this app are generally of a very high quality. We did find a few pretty average slots, but there are some top hits in there if you take the time to find them.
You can also use the app to access an abundance of sports betting markets from one of California’s best sports betting sites. Most of these come with competitive odds to match.
BetOnline doesn’t just do mobile casinos — it nails them. Smooth, detailed, and easy to use, their mobile site is a pocket-sized MVP for players on the go.
Something else that unexpectedly impressed us about BetOnline was the choice of live casino games. There are more than 70 here, including blackjack, roulette, and baccarat. You won’t find niche game shows, but that’s still an impressive haul of rooms.
And if you’re a fan of crypto casino gaming, you can choose from around 15 digital currencies to bank with, all of which come with superb transaction limits for high rollers.
