Best Online Casinos in California in 2025

While there’s been some push to bring online casinos to California, nothing has materialized since May 2025. With that, sweepstakes casinos are filling that void, offering players casino-style games without needing a traditional gaming license. 

How so? Good question—sweepstakes casinos can operate because they offer casino-style games, and you can redeem real cash prizes without ever needing to make a purchase. 

Below, we’ll examine the top sweepstakes casinos in California, how we rank them, what we look for, what casinos to avoid, and more. 

Let’s dive in. 

Picking the top sweepstakes online casinos in California will all come down to what is and isn’t important to you. That said, we can examine some general attributes when considering a sweepstakes casino as a top platform in California and elsewhere. 

For example, regarding the welcome bonus, does the casino provide real value to the player? This is a chance for a good first impression. 

As you continue to read below, I’ll examine California's top 12 online sweepstakes casinos, providing a quick summary and a table with information about each. 

In no particular order, let’s examine those 12 sweepstakes online casinos in California. 

Game Variety

The more games there are at an online sweepstakes casino, the better. I value an extensive game library, but there must be quality titles, slots, blackjack, baccarat, or other table games. Additionally, I look for top game providers like Relax Gaming or Pragmatic Play.

Payment methods

Like with games, more options are better. A wider array of payment options allows for more players to get involved. While a limited selection isn’t a dealbreaker, it can influence a player’s decision when choosing a site.

Mobile experience

Let’s face it, most people play at California online casinos on their phones. I test each site’s mobile platform, whether the mobile app or web browser, to ensure smooth gameplay, easy navigation, and overall functionality.

Security and Safety

California allows sweepstakes casinos to operate under sweepstakes laws. I can confirm there’s nothing to worry about regarding safety. As for security, I’ll examine each site to see what encryption is offered on payments.

Features

This is subjective, but I will examine each sweepstakes casino to find unique features and see where each platform shines. This could be simple as the user interface design or a loyalty program.

Customer support

Like the games and payment methods, I look for sites offering many customer support avenues. Players should have access to the sweepstakes casino to ask questions when needed. Additionally, I'll test to see how responsive customer support is and how they address questions.

California Online Casinos to Avoid

While I won’t name any names here, I can tell you what attributes/qualities to avoid in an online sweepstakes casino. 

Bad Customer Support

While I’m not a fan of live chat being locked behind making purchases, what’s even worse is that the available customer support isn’t good. For example, if a customer service representative doesn’t understand their product, including things regarding redemptions or purchases.

Poor Payment Options

You always—and only—want to use casinos that offer legitimate payment methods.

Negative Reviews or Complaints

There will be some negative reviews that could be from a jaded player, but if you notice a consistent pattern of negative reviews, especially on the same subject, tread lightly.

If you’re interested in and ready to play at California online sweepstakes casinos, here’s how to get started. 

• Creating an Account: Go to the site you’re interested in, whether a mobile app or a desktop page. Click Register or the equivalent link (perhaps Sign Up or  Join Now). Next, you’ll be asked to provide some personal details. At sweepstakes casinos, it’s normal for the initial registration to be a few quick steps, but later, you’ll need to provide your name, date of birth, and address for redemptions. You may also need to provide a copy of your driver’s license.
• Making a Purchase: Back on the homepage, click Get Coins. This will show all the available coin bundles. Choose one of the available payment methods and complete the process. Note: Purchases at sweepstakes casinos are optional, and players are not required to play or redeem sweepstakes coins.
• Choosing a Game: Once you’ve logged in, received your welcome bonus, and, if you so choose, made a purchase, head back to the homepage and investigate the game library to see what stands out to you.
• Placing Bets and Playing: Open the game with Gold Coins or Sweepstakes Coins. Sweepstakes coins can be redeemed for real cash prizes, whereas Gold Coins are strictly “for fun” only.

There are some online sweepstakes casinos in California where you can explore the site and play without officially creating an account. However, you'll eventually need to make one to redeem sweepstakes coins or receive daily login bonuses. This option lets you get a feel for the site and games to see if you enjoy them.

California has many great online casinos, but some stand out in specific areas. Offshore or international sites might also seem appealing. 

Below, I’ll break down the key differences to consider.

Local vs International Online Casinos

Additionally, I’d strongly suggest playing at a sweepstakes casino instead of an offshore one. 

There’s no recourse with an offshore casino, whereas with sweepstakes casinos in California, you can contact various organizations, like the Better Business Bureau, their business registry (some sweepstakes casinos are registered in Delaware), and more. 

Sweepstakes casinos are simply a safer option all the way around. 

Throughout the various sweepstakes casinos in California, you’ll encounter a lot of games. Most platforms will have slots, but others will have more, such as live dealer games, table games, and perhaps even other “variety” games like scratchcards. 

These platforms will have hundreds of games. 

Below are three popular slot games and where you can find them.
