Best California Online Casinos
- Ignition: Best overall – $3,000 welcome bonus
- BetOnline: Fastest payouts
- Slots of Vegas: Top pick for slots
- Queen Bee Casino: $5,000 welcome bonus
- Super Slots: Biggest jackpots
With the best online casinos California laid out, let’s dig into why our list is a cut above the rest of the competition.
1. Ignition — Best Online Casino in California Overall
Pros:
- $3,000 welcome bonus
- 400+ casino games
- Juicy Hot Drop jackpots
- Huge selection of blackjack tables
- Fast payouts
Cons:
- The homepage is a bit cluttered
- Customer support is a bit slow
Ignition proudly sits atop our list of the best California online casinos for good reason; not only does it have one of the most generous bonuses on the market, but it strikes the perfect balance between slots and table games.
Game Selection: 4.9/5
While having 400+ games may not seem impressive in a sea of casinos that offer thousands of different titles, Ignition sets itself apart with how well-curated its gaming library is. You won’t find endless copies of the same game just to pad their stats. Rather, each game has been hand-selected to fill any gaps in the library.
On the slots side of things, that means that cartoonish games like Coins of Leprechaun Hold & Win sit next to more mature titles like the steamy A Night with Cleo. For table games, it means a wide selection of unique blackjack variants, rather than multiple iterations of the same basic 21.
After the biggest payouts? Then check out the Hot Drop jackpot games, which have prizes that are guaranteed to pay out either daily or hourly. You can also skip the guarantee entirely and chase their Epic Jackpot, which starts in the six figures and grows from there.
Bonuses and Promotions: 4.8/5
If you deposit with crypto, you can get a 150% bonus match up to $3,000. Everyone else gets a 100% match up to $2,000, which is still quite good.
The bonus has a quite reasonable 25x wagering requirement attached. Ignition also offers weekly boosts to players, as well as daily rewards and live dealer jackpots.
Banking Options: 5/5
There are two ways to fund your account: one is with methods like credit cards and cryptocurrency, and the other is via their innovative MatchPay system.
They accept all four major credit cards, plus seven cryptocurrencies. Using these is straightforward and simple, and cashouts can be handled nearly instantly if you use options like Bitcoin.
On the other hand, their MatchPay system lets you use virtually any banking system you like, including Zelle, Venmo, and CashApp.

2. BetOnline — Fastest Payouts of All California Online Casino Sites
Pros:
- Over 1,300 games to play
- Regular VIP perks like cash boosts
- Most cashouts in minutes
- 100 free spins for new players
- Dedicated online sports betting section
Cons:
- Could use a better welcome bonus
- Design is not ideal
Looking for the fastest payout online casinos in California? Then make sure to take a look at BetOnline, it processes most withdrawals within a few minutes!
Game Selection: 5/5
There are around 1,300 different titles to play here, and while most of those are slots, you’ll also find a good selection of table games, instant wins, and live dealer tables.
In the slots category, we have exclusive titles like Triple 7s and Dragon Fortune Frenzy, as well as huge hits like Big Boss Bonanza and Reels & Wheels XL. Regardless of whether you like bonus buy games, megaways, or classic options, you’ll find plenty to choose from here.
You can also try your luck at one of the 50+ blackjack and roulette tables — and that’s not even counting the live dealer options. The specialty games are also a ton of fun, especially shooting games like Sea Treasures or arcade-style romps such as Plinko Blitz.
Bonuses and Promotions: 4.85/5
The welcome bonus here is a bit unconventional, and we suspect some players will love it while others will find it a bit lacking.
Instead of a deposit match, they offer new players 100 free spins on one of their biggest hit slots. The good thing about this is that it makes the bonus very easy (and fun) to earn, but if you’re looking for an eye-popping cash prize, this ain’t it.
There aren’t many promos to redeem here at all, in fact, but they make up for that with a rewarding VIP program.
Banking Options: 4.9/5
There are more than 15 different cryptocurrencies you can use to get money on and off the site, ranging from big names like Ethereum to lesser-known options like Polygon. Deposit minimums for these coins are low (around $20), and cashouts should happen in less than an hour.
As for fiat currencies, you can deposit using credit cards, money orders, or person-to-person transfers. Cashouts will take longer, though, and there may be fees assessed along the way.

3. Slots of Vegas — Best Online Casino California Site for Slots
Pros:
- $2,500 bonus + 50 free spins
- 50% cashback available
- 7-figure jackpots
- Regular freeroll tournaments
- Can buy crypto directly through the cashier page
Cons:
- Customer support is a bit slow
- Could use more table games
Next up, we have Slots of Vegas, and as its name suggests, it is the best site for slots in California.
Game Selection: 4.7/5
The game selection here is small but mighty, as there are around 300 real money casino games to enjoy. As you might expect from the site’s name, slots are the main event, and you’ll find some seriously impressive jackpots to chase (think $1 million+).
As for table games, the selection isn’t necessarily impressive, but it does cover all the necessary bases. With games ranging from blackjack and roulette to Andar Bahar and Teen Patti, there’s plenty besides slots here.
Fun fact: Slots of Vegas is also one of the best casinos in Virginia right now.
Bonuses and Promotions: 4.8/5
New players can get up to $2,500 and 50 free spins when they make their first deposit using code WILD250. This bonus has an extremely low 10x playthrough requirement, making it one of the easiest to earn among Golden State casinos.
You’ll also get new offers in your inbox every day, ranging from free spins to reload bonuses. Additionally, the VIP rewards are excellent, including the aforementioned 50% cashback.
Banking Options: 4.9/5
Slots of Vegas accepts three major credit cards (sorry, Discover), as well as seven cryptocurrencies. If you cash out with crypto, expect to get paid in a matter of hours.
Don’t have any crypto? No worries; you can buy it directly through the site via Changelly. It’s a nice touch that will make using altcoins more accessible to the average player.

4. Queen Bee Casino — Best Bonuses of All Online Casinos in California
Pros:
- $5,000 welcome bonus + 200 free spins
- 300+ casino games
- 15% weekly rebate available
- More than 15 cryptocurrencies
- Amazing mobile experience
Cons:
- Slow fiat cashouts
- The design is not the best
If you want to get started on the right foot, there is few better ways to do it than by cashing in a big welcome bonus. Queen Bee has one of the biggest we’ve found!
Game Selection: 4.8/5
With over 300 games to explore, slots fans will never be bored here. Some of the options available include Blazing Buffalo, Coins of Ra Power, and Elvis Legend, each of which has proven to be massively popular over the years.
The live dealer section is filled with fun games as well, with over two dozen blackjack tables, 19 roulette tables, and a handful of poker and baccarat options.
Other than the slots, though, it’s the instant win games that stand out the most here. There are various specialty titles that don’t fit in traditional categories, like Tiger Crash, Penguin Rush, and Gridiron Gold.
Bonuses and Promotions: 5/5
You can get up to $5,000 in bonus cash on your first deposit to go along with 200 free spins – and that’s just the beginning! Queen Bee Casino is also home to various reload bonuses, including regular tournaments and contests.
While it’s a lot of hoops to jump through, the end result is well worth it. Be aware that the 333% bonus has a 45x wagering requirement, while the other two have just a 40x playthrough.
Banking Options: 4.7/5
Another crypto-heavy site, this one accepts more than 15 different coins, including the likes of Avalanche, Binance, and even TrumpMeme. The minimum deposit levels are low ($10-20), and the maximums are high, often capping at the $1 million mark.
Things are a bit different on the fiat side of things. You can use any of the four major credit cards to deposit, as well as money orders, but your cashout options are limited to money orders, wire transfers, and bank checks.

5. Super Slots — Biggest Jackpots of all California Casino Sites
Pros:
- Dozens of jackpot games
- 300 free spins welcome bonus
- Over 1,200 casino games
- Excellent live dealer titles
- Offers both cash and freeroll slot tourneys
Cons:
- Design could be better
- Could use better bonuses
Last but not least, we have Super Slots, our favorite site for jackpot games.
Game Selection: 4.7/5
There are well over a thousand games here, including some massive jackpot slots. The video poker selection is great too, with about 40 titles in all, and there’s even a section dedicated to exclusive titles.
However, the live dealer casino steals the show, thanks to its sophisticated ambiance that perfectly mimics the brick-and-mortar experience.
Throw in some fun games like casino poker, baccarat, and game shows like War of Bets, and you have an experience that’s worth skipping the crowds for.
Bonuses and Promotions: 4.6/5
Like BetOnline, Super Slots awards free spins to first-time depositors rather than cash. You’ll get 300 such spins here, but you should know that your wins will be capped at $100, and you only have 24 hours to use them.
Other promos include daily cash races, slots tournaments, and a weekly reload bonus, but the true rewards come over time. As you rise through the ranks of their VIP program, you can get all sorts of special perks, giving you all sorts of reasons to bookmark this casino.
Banking Options: 4.7/5
As with many other California online casinos, your options are pretty much limited to credit cards and cryptocurrencies. Luckily, they accept a wide variety of both, so buying chips isn’t a hassle.
Your experience cashing out will depend largely on the method you use. Some coins, like Bitcoin and Tron, have low cashout minimums, while others (Tether and Ethereum, notably) require you to cash out $200 at a time.

Casino Games with the Highest Payouts in California
Looking for the games that actually give you a chance to come out ahead? We dug through each site’s catalogue to find the titles with the highest RTP, so you can get the most value for your money.
Online Slot with the Highest Payout: Dragon’s Siege
With a 98% RTP, this is one game you can often play for hours at a time without needing to top off your account. Filled with wilds and multipliers, the real star of the show is the progressive jackpot, which starts out huge and just grows from there.
>> Play Dragon’s Siege at Ignition
Highest-RTP Blackjack Option: European Blackjack
While all blackjack games have high RTPs when played correctly, European blackjack is the best of the bunch, as it has a tiny 0.39% house edge.
>> Play European blackjack at BetOnline
Most Rewarding Online Roulette Game: European Roulette
Having just a single zero on the wheel makes a world of difference, as it effectively cuts the house edge in half. If you play even-money bets like red/black or odd/even, your RTP should sit somewhere around 97.3%.
>> Play European roulette at Queen Bee Casino
Best Poker Game: Deuces Wild
While there are different variations of this game, most of them have an RTP solidly north of 99%. In fact, there are certain full-pay Deuces Wild games that have an RTP higher than 100%!

Banking Options at California Online Gambling Sites
For many Californians, playing online casino games isn’t the hard part — getting money on and off their account is. Many payment methods are restricted for residents here, but most sites accept at least some of the following:
Credit Cards
Most casinos accept Visa and Mastercard for deposits, and some also take Discover and American Express. However, you won’t be able to withdraw from your card, so you’ll have to find another option.
E-Wallets
While less common than credit cards, e-wallets like PayPal, Skrill, and Neteller are another way to get your winnings. Deposits are instant, and withdrawals typically arrive within 24 hours.
Cryptocurrencies
Bitcoin and other cryptocurrencies offer the quickest payouts, often within a few hours. Many players prefer crypto because there are usually no fees and higher privacy, plus crypto depositors are often eligible for special bonuses not available to their fiat counterparts.
Bank Transfers
Wire transfers and ACH transfers are available at most casinos, but take the longest time to hit your account. Expect 5-7 business days for withdrawals, though they’re reliable for larger amounts.
Available Bonuses at CA Online Casinos
One of the biggest reasons to play at an online casino is the fact that there are so many more bonuses available to new and existing players alike.
Here are a few bonuses you can claim today:

| Reload Bonus | Similar to a welcome bonus, except for established players | Many sites offer these on an ongoing basis | Often not as large as welcome bonuses | Ignition |
| Cashback | An offer where you’re refunded a portion of your losses | Offer ongoing value, rather than the one-time benefit of a regular bonus | Only get the money if you lose | Slots of Vegas |
Tips for Using Online Casinos in CA
If you’ve never played at an online casino before, there are a few things you should know before you get started. Here are some of the best tips we have for new players.
Set a Budget Before You Play
Decide how much you can afford to lose and stick to it. Never chase losses with bigger bets.
Remember that gambling is supposed to be fun, not a way to make money. The house always wins in the end, so treat the money like an entertainment fund, not a second income.
Read Bonus Terms Carefully
While a big bonus might look enticing on the surface, wagering requirements and game restrictions hidden in the fine print can make bonuses harder to use than they appear.
Look at the wagering requirements first; anything above 25x is on the high end. Also, check the expiry period, as some bonuses only give you a week or two to earn them.
Start with Free Games
Try demo versions to learn rules and find games you enjoy before risking real money.
This is an especially good strategy if you’re playing certain games for the first time. Playing in demo mode allows you to get a good feel for the action without any pressure involved, and that can save you a ton of money (and mistakes).
Take Advantage of Loyalty Programs
Most sites have loyalty programs where regular play earns points you can redeem for bonuses, cashback, or other perks. These are free to join, and the more you play, the more you can earn.
As you climb the ladder, you’ll get access to better perks, like special bonuses, faster cashouts, and much more.
Play When You’re Alert and Sober
Avoid gambling when tired, stressed, or under the influence of alcohol or drugs. Luckily, when playing at home, you won’t constantly be tempted by free drinks or carefree companions, making it easier to stay in control.
Ready to Try Your Luck at the Best Online Casinos in California?
Online casinos offer California players an exciting way to enjoy their favorite games without leaving home. With hundreds of slots, table games, and live dealer options available 24/7, there’s always something new to try.
