Best California Online Casinos in 2025 – What’s the Top Online Casino Site for Cali Players?

California. The Golden State. There’s all sorts of action happening here 24 hours a day, 7 days a week. And in recent years, it’s turned out to be a premier destination for online casinos.

The uprising of the California online casinos has not gone unnoticed by our two experts, in-house iGaming pros John and Peter. They’ve been monitoring things carefully, and with that, they are now ready to pick out a selection of the top sites for you, our readers.

These two have been in the casino industry for many years, so they’re pretty rigorous with their review processes.

On that note, let’s hand things over to John and Peter so they can show you the best places to play online casino games in California.

Best California Online Casinos

Meet the Authors

John

John has been professionally facing off against dealers for over five years. His expertise spans various popular online casino games, and he always finds excitement in the fast-paced digital environment. Although he enjoys the atmosphere of local venues, his heart lies with the thrill of online gaming.

When he’s not at the tables, John enjoys poker, betting on sports, writing about gambling, and helping newcomers navigate the online gambling scene.

Peter

Peter famously won over $100,000 in one spectacular gaming session, and he loves recounting that story whenever he gets a chance.

He prefers playing multiple hands simultaneously, thriving on the adrenaline rush it brings. Outside of gaming, Peter is interested in cryptocurrency and follows the Giants, hoping for a comeback season.

How Our Review Process Works

Our experts, John and Peter, pride themselves on their formula for selecting the top online casinos worldwide. They’ve been kind enough to give us an exclusive insight into the process.

Step 1: Crunching the Data

First things first, John and Peter do some background research on California’s online casino sites. Our experts then review a list of casinos across the state and all the important stats about each one.

These include the number of different types of games each of them has to offer, the choice of bonuses, the list of game providers, the speed of the payouts, the mobile compatibility, and a whole lot more. With this, they’ll get a shortlist of great online casino sites.

Step 2: Trying Out Some Online Casinos

The next step of the process is to narrow down that shortlist a little further. So, they sign up for accounts with each of the casinos on their shortlist. This allows them to get a feel for what the site is like to use for a start.

They’ll check out all of these sites on mobile and desktop devices to ensure that each is satisfactory for both.

Step 3: Conducting Further Tests and Reviews

After narrowing down the list, I realized there’s still more work to be done to find the very best online casinos in California.

So, now it’s time to test out further factors of each site. They’ll perform checks on customer support, for example. They’ll also request a payout or two here to find out how fast this process takes place in practice.

Step 4: Making Final Selections from the Picks

With all of their data collated, John and Peter are able to make their final top picks. Of course, they split up at this point to decide which online casino is best for what factor and which is their favorite overall. In the case of CA casinos, they disagreed on each factor here.

After this, we passed on John and Peter’s findings to Marijana, our official, in-house fact checker, to ensure that all of the data they had collected was as accurate as possible.

Now, it’s time to show you everything John and Peter discovered when they set about finding the top online gambling California sites.

All-Round Best California Online Casino

John: Ignition

I’m pretty confident that Ignition is the best online casino in California overall. I’ve been hearing about this site for many years, and when I finally got the chance to try it out in person, I was not disappointed.

There’s a pretty good selection of games here, that’s for sure. I counted a little over 300, which obviously isn’t the largest amount, but it’s the quality that counts. The poker room here is exceptional – there’s always a table to join.

Perhaps the factor of Ignition that stands out the most for me is the progressive jackpot slots. There are dozens of these, with various max wins all the way up into the $100,000s. You can play all of them with a neat $3,000 welcome bonus package if you choose to bank with crypto.

Peter: BetWhale

I’m actually inclined to disagree with John here and say that the best California online casino is BetWhale. Why? Well, it’s more of an all-rounder. I found it hard to fault anything about this online casino other than a couple of minor details, so it’s going to be a good option for most people.

Look past the mediocre site design, and it becomes clear that this is one of the best, if not the best, casinos in California right now. That all starts with a pretty grand welcome bonus: a 150% deposit match.

There’s a healthy number of games here, too, at over 700. I was pretty impressed by this, especially considering that this is a site that considers itself to be a sports betting site more so than an actual casino.

Best California Online Gambling Site for Slots

John: Slots of Vegas

The entire slot game collection of Slots of Vegas comes from RealTime Gaming, which I’ve always found to be one of the most reliable and consistent slot game providers in the world. The choice of their games at this site definitely backs that up.

A couple of RTG slots available at Slots of Vegas that I particularly like are Mask of the Golden Shrink and Dragon Winds. Both of these have really neat graphics and cute themes, as well as some fun in-game bonus rounds to keep things interesting.

One thing I want to mention is their welcome bonus – I nearly chose the 250% up to $2,500 deposit match and 50 free spins new players can get here as my top welcome bonus overall, especially considering that you only have to play through it five times.

Peter: Raging Bull Slots

Raging Bull Slots has a highly similar game selection to John’s pick, Slots of Vegas, so you could opt for either and have some fun if slots are your game of choice. Again, the whole collection here has been supplied by RealTime Gaming, which is one of the best out there. And let me tell you, the slot lineup here is raging-ly good!

Moreover, I was impressed that a lot of the slots at Raging Bull Slots have progressive jackpots. Not all of them have massive jackpot amounts, but any kind of jackpot win is worth shooting for, in my opinion.

I also feel like it should be pointed out that you can play all of the Raging Bull Slots games for free in demo mode. If you’re not sure which of the games to try, this is a great way to test them out without spending money. You can get a bit of practice by going down this route as well.

Best Bonuses of All Online Casinos in California

John: Super Slots

For me, it’s pretty clear that Super Slots has the best casino welcome bonus in California right now. If you want to pay with fiat currency, you can get up to $6,000 in cash as a new player. That’s going to be split across your first five payments, starting with a 250% up to $2,500 deposit match.

I like the crypto bonus here as well. This one is a 400% up to $4,000 deposit match. It’s not often I’ve seen a casino offering a bonus with a deposit match percentage as high as this.

Actually, there are loads of bonuses for existing players at Super Slots as well. I found a whole lot of reload bonuses here, which is not always the case with sites throwing the kitchen sink at their welcome offer. Free spins and matched deposits are available on multiple days of the week.

Peter: Slots of Vegas

While I agree that Super Slots has some fantastic offers for new players, the wagering requirements put me off a bit. Personally, I’d rather opt for a slightly smaller welcome offer to have to play through less wagering, as this just makes life a whole lot easier.

And that’s why I’ve picked Slots of Vegas as the best online casino welcome bonus in California. Their current offer is a 250% up to $2,500 deposit match that also comes with 50 free spins.

This is seriously low, a heck of a lot lower than just about every other online casino bonus I’ve ever come across. The result of this is that it’s going to be a whole lot easier to play through your winnings. Then, you can get back into playing whatever games you want to.

Best Online Poker Casino in California

John: Raging Bull Slots

I’m a big fan of video poker, and I found a lot of great examples over at Raging Bull Slots. RealTime Gaming is in charge of the video poker games here, and that’s good news, as they’re one of the best video poker games out there.

You can play Jacks or Better, Pick ‘Em Poker, Double Jackpot Poker, and a few other options, so there is a good range of choices overall.

If you want to move on from poker, the slots here are good, as Peter has already mentioned. I was able to play a handful of live games here as well, but you will need to sign up for an account to be able to do so.

Peter: Ignition

I love actual poker rooms rather than spending time on video poker. Naturally, I’ve opted for Ignition for this award. I think it has the best live poker setup in California, and that’s really saying something.

For a start, there are loads of great bonuses that you can use to play poker with, including free rolls and more. Also, there are loads of different types of poker tournaments to suit all types of players, and each of them is delivered with very high quality.

That’s not to say that Ignition is no good for video poker, though. In fact, I actually think the video poker here is just as good as it is at Raging Bull Slots. There are a handful of options covering a wide range of themes, and most of them come with some good payout potential as well.

Best Live Dealer Casino in California

John: BetWhale

If you want to play live dealer games in California, I recommend checking out BetWhale. This online casino offers over 70 different types of games, covering a wide range of bases.

I found examples of loads of game shows and particularly enjoyed trying Wheel of Fortune and Football Grid for something new. As is often the case with any live dealer site worth playing at, these games come alongside a whole bunch of blackjack and roulette games.

The quality of the games appears to be strong across the board, thanks to a wide range of bet levels, different variants of each game, and professional live dealers who help to bring the gaming experience to life.

Peter: BetOnline

There are literally over 70 live casino games to play at BetOnline, so for me, it’s kind of a no-brainer that this is the number one live dealer casino game site. I found loads of options from Visionary iGaming and Fresh Deck Studios as well, and these are two of my favorite developers.

They’re really good names if you want to find the highest RTPs, and they’ve delivered plenty of payout potential to BetOnline. I liked the fact that BetOnline has picked out some pretty unique games as well, including War of Bets and Dice Duel.

If you’d rather opt for something more conventional with your live casino games, then you’re also going to find a whole lot of roulette, blackjack, baccarat, etc. You can play some of these for as little as $0.50, which is good news for the casual gamers of California.

Best California Mobile Casino

John: BetOnline

My top CA mobile casino is BetOnline. Sure, there aren’t actually quite as many games to play here as there are at some of our other selections, but the fact that you can play all of them on the mobile site is important news. It’s also key that the mobile site is very well-designed and, therefore, visually pleasing.

And even if there aren’t quite as many games, at least the ones they do offer are good. As Peter noted, the live dealer games are really strong, and I found a few very good slot games as well. I’ve definitely seen California casino sites with fewer quality options.

It’s actually a pretty impeccable place to be for online sports betting as well. BetOnline is very much a classic California sports betting site, with 1000s of daily betting markets and a lot of competitive odds to back them up. You can enjoy great mobile sports betting with them as well.

Peter: Super Slots

John might have picked Super Slots for its bonuses, and I’m inclined to agree with him to some extent. But actually, I think their real area of expertise is their mobile gaming. My research showed that almost all of their 1100+ casino games can be played through the mobile site.

Some of the slot games come from providers I’m not too sure about, but you can easily skip over them to find easy mobile slots from the likes of Betsoft. There are over 70 live games to play here as well, and even those are pretty easy to play on the mobile site.

This is one of the most simply designed websites as well, and that makes it really easy to use for someone who isn’t quite as tech-savvy as the younger generation. I also have a pretty useless old phone, but I didn’t have any issues loading up Super Slots on it.

Top California Online Casino Games to Play

If you pick the right online casino site in California, you’re going to have access to an abundance of casino games. Check out a few of your options below.

Slots

There’s unlikely to be a more popular type of online casino game to ever be released than the slot. We’ve seen literally tens of thousands of online slot machines, and yet they keep on coming due to the immense demand for them.

Why are they so popular? Well, the ability to customize the experience to suit your taste in terms of themes is definitely one thing. The ease of gameplay helps as well, and the speed of play adds to that. There are loads of reasons, really!

Peter says: “You’re going to have a lot of options to work with when you play slots online. Make sure to take the time to work out which theme you like, but most importantly, which reel mechanics and in-game bonuses you want to play with.”

Blackjack

The classic card game of 21 is highly abundant at California casinos online. You’d be unlucky to find a site that doesn’t have a whole lot of both live and non-live online blackjack games that have a lot of payout potential.

Blackjack has two main variants: European and American. However, it also has several offshoots with different bonuses, rules, etc. These include Blackjack Switch, Multihand Blackjack, and more.

John says: “I’m probably pretty biased when it comes to blackjack, but I’d say it’s just about the best game out there. When you play it online, it comes with some of the highest payouts around. For example, some blackjack games have 99% RTP+. That’s pretty crazy.”

Roulette

There’s nothing more iconic in the casino world than the classic roulette machine. This iconic device has made its way into the online casino domain for players in California in fine style and in a wide range of live and non-live forms.

Again, you’ll typically be able to play both European and American Roulette. However, there are also a number of other forms of it that appear online. A couple of examples are Double Action Roulette and Multi Wheel Roulette.

Peter says: “First things first, I recommend playing live roulette as it tends to pay out better on average. On top of that, it’s generally better to play European Roulette instead of American Roulette if you’re betting on red or black, as the one less zero will narrow your odds.”

Specialty Games

These days, there are a lot of different types of casino games to play in California outside of the conventional online casino games. Scratchcards, Plinko, crash games, and more all offer unique and intriguing casino gaming experiences that set new trends in the modern casino world.

Of course, each of these games has different rules and objectives, so make sure to take the time to figure out exactly what you need to do before you play them. If you do this, the experience can be very rewarding.

John says: “If you like the idea of playing a casino game that isn’t conventional and is a little more modern, then I recommend playing some crash options. These are a lot of fun and very unique. Check out Triple Cash or Crash at Ignition, as this is one of the best examples.”

California Casino Apps: Playing at CA Casinos On Mobile

Nowadays, most gambling sites in California can be accessed on mobile devices, and the same can be said for most individual online casino games. Modern development technology has allowed game producers to scale their websites and games down to smaller screens more easily.

As a result, casino game fans in California have the freedom to play their titles no matter where they go. All they’ll need is a mobile phone that’s powerful enough to load the games and a stable internet connection.

A small download to offshore casinos is that you won’t be able to download an actual mobile app to play them on. Instead, you will have to host the sites through your smartphone browser.

This means that you won’t get to play them in full screen, and they might not load quite as quickly. Nonetheless, there are still some very well-designed mobile sites out there. For example, our expert, John, picked BetOnline as the best California mobile casino site. Peter, on the other hand, opted for Super Slots.

Our experts have traveled the world! They even explored Australian online casino sites and rated them in this guide.
