Mobile casinos California players can open on a phone are offshore sites, and almost all of them run in the browser rather than through an app. California licenses no online casino, so no real-money casino app is approved for the state. This page explains apps versus browser play, what works on a phone, mobile banking, security and the limits worth setting.
California licenses no online casino, so there's no state-approved real-money casino app.
Offshore partner casinos run in a phone browser; their own sites or reviewers list no dedicated mobile app.
Silver Oak's own mobile page lists browser play for iPhone, Android and tablets, with RTG slots such as Storm Lords and T-Rex II.
Sweepstakes casino apps are covered by California's AB 831 ban from January 1, 2026.
Phone blocking tools such as Gamban cost $6.99 a month or $41.99 a year, with a seven-day free trial.

Are mobile casinos legal in California?
California has no law that licenses online casinos, so no mobile casino holds a California license, whether it's an app or a website. Playing on a phone doesn't change the legal position compared with a laptop. The Gambling Control Commission (opens in a new tab) and the Bureau of Gambling Control oversee tribal casinos and cardrooms, not phone apps.
Sites that accept Californians on mobile are offshore operators that no US state licenses or regulates. In practice that means no state regulator to complain to, no state protection of your balance and terms the casino sets itself. Our hub on online casinos in California and the California gambling laws page set out the statutes.
Casino apps vs browser play: how offshore mobile casinos work
Offshore casinos usually skip the app stores and run as mobile websites. You open the casino's website in your phone's browser and log in, with nothing to install. Our instant play vs download guide explains the trade-offs.

Because there's no app to install, there's also no app-store listing to vet the casino. The responsibility for checking who runs the site falls on you, which is why the checklist further down matters.
Why there's no real-money casino app for California
State-licensed online casino apps exist only where a state licenses online casinos: New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island. Maine legalized tribal-run online casinos in January 2026, but nothing had launched by October 2026. California isn't on the list, so no licensed operator can offer a real-money casino app to players in Los Angeles, San Diego, San Jose or anywhere else in the state.
Sweepstakes casino apps in California after AB 831
Sweepstakes casinos did have apps; third-party trackers list Chumba Lite on the App Store and Google Play, for example. But AB 831 banned dual-currency sweepstakes casinos in California from January 1, 2026, and most major brands now list California as excluded. Having an app on your phone doesn't make the product available in the state.
Offshore partner sites mostly run RealTime Gaming slots, which are built to scale to phone screens. Silver Oak's own mobile casino page (opens in a new tab) says it has over 200 games on mobile and names Magic Mushroom, 777, T-Rex II, Storm Lords, Cash Bandits 3, Vegas Lux, 5 Wishes and Fortunate Zeus. Third-party reviews report Cash Bandits 2, Paydirt!, Sweet 16 and Pirate Isle 3D in Planet 7's lobby, along with blackjack and video poker variants.
Live dealer tables aren't listed at either casino. Lobbies change, so check the casino's mobile lobby for a specific title. Our California slots page covers RTPs and what a slot session costs in dollars, and the mobile casino guide covers screen and data basics.
Adding a mobile casino to your home screen
Without an app, the closest thing is a browser shortcut. SlotoCash's support page suggests adding one to your home screen, and the same approach works for any browser-based casino.
Type the casino's address yourself or use a bookmark you saved from its official site, never a link from an ad or a message.
Check the address bar carefully. Unofficial mirror sites copy casino names, so make sure the domain matches the one the casino publishes.
Use your browser's share or menu option to add a shortcut to the home screen.
Open the shortcut and log in. Turn on any extra security the casino offers.
Set a screen-time or app limit on the browser if you want a reminder of how long you've played.
Mobile casino banking from California: crypto and cards
The cashier works the same on a phone as on a computer. Card deposits to offshore casinos often fail because gambling charges carry merchant code 7995, which many US issuers block; see card declines. That's why crypto dominates offshore mobile banking.
Deposit options and fees at the two casinos on this page
Paying from a phone wallet is convenient, but crypto payments generally can't be reversed. Our crypto casinos in California page covers withdrawal times, fees and price swings.
Mobile casino safety: security and verification on your phone
A phone holds your email, banking apps and camera, so protect it. Use a strong unique password for each casino and turn on two-factor authentication where it's available. Be wary of texts or emails with casino bonus links; see our phishing scams guide.
Most verification now happens through the phone camera. Silver Oak's terms (opens in a new tab) ask for government photo ID, the front and back of cards used in the last three months, a selfie with your ID and a utility bill from the last three months, and block withdrawals until checks are complete. Third-party reviews say Planet 7 asks for ID, proof of address and a selfie with ID, and reviews documents in zero to three days. Send them over a secure connection rather than public Wi-Fi, and read how to verify your casino account.
Phone-friendly limits and blocking tools
Phones make it easy to play anywhere and at any hour, so build in friction. Silver Oak's terms list deposit limits, cool-off periods and self-exclusion processed through live chat. One third-party reviewer lists no self-service tools at Planet 7, so ask support in writing if you need limits there.
Blocking apps work across the whole phone. Gamban (opens in a new tab) costs $6.99 a month or $41.99 a year after a seven-day free trial and is on the App Store and Google Play. Our blocking software page compares options. The National Problem Gambling Helpline is 1-800-MY-RESET (1-800-697-3738), by call, text or chat at ncpgambling.org (opens in a new tab), and California's Office of Problem Gambling runs the state program.
How to check a mobile casino before you deposit
Confirm the legal position. California licenses no online casino, so any real-money site is offshore.
Find the operator and license in the casino's terms, and note any conflicts with third-party reports.
Look up regulator actions, such as the Michigan Gaming Control Board's cease-and-desist letters.
Read the withdrawal caps, fees and processing times on the banking page.
Check verification rules and send documents before your first withdrawal.
Set a deposit limit and a time limit before you play.
Silver Oak and Planet 7 are shown here because both run their RTG lobbies in a phone browser on iPhone and Android, which fits this page's topic.

Offers are for new players aged 21+ (18+ where allowed), and terms apply.
Silver Oak: $2,500 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). The casino's own site advertises a different package: 100% on each of the first ten deposits up to $10,000, with no free spins. Its offer page says 30x playthrough and "no max withdrawal", but its terms say 40x on slots and 60x on table games and video poker; deposits start at $30.
Planet 7: $2,750 Welcome Bonus + 45 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Third-party reviews list a 200% match (code WELCOME200) at 30x deposit plus bonus on slots with a $1,000 max cashout and a $30 card minimum. Codes change, so check before depositing.
Check the terms shown at sign-up; those apply. Bonuses are for slots, and table games are usually excluded or weighted lower. Silver Oak's terms name Primrose Media Limited, licensed in Anjouan, while some reviewers list no license; third-party reviewers say Planet 7 has no license or a Costa Rica license. The Michigan Gaming Control Board named both in cease-and-desist letters on April 9, 2025 (opens in a new tab). Read the Silver Oak mobile casino page and the Planet 7 review first.

Frequently asked questions
Are mobile casinos legal in California?
No mobile casino is licensed in California, because the state licenses no online casino at all. Offshore sites still open in phone browsers, but no US state supervises them, and sweepstakes casino apps fall under the AB 831 ban from January 1, 2026. Read can I play online casinos in California for the short answer.
Is there a real money casino app for California?
Not a state-approved one. Licensed real-money casino apps exist only in New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island. Offshore casinos that accept Californians run in the phone's browser instead, and the partner sites list no dedicated mobile app. See is there a casino app for more.
Can I play casino games on my iPhone in California?
Offshore casinos run in Safari on an iPhone; Silver Oak's own mobile page lists iPhone, Android and tablet play. That doesn't change the legal position: California licenses no online casino, so these sites are offshore and unregulated by any US state. Our playing on iPhone guide covers setup and safety.
Do California mobile casinos have the same games as desktop?
Mostly, at the RTG-based offshore sites that accept Californians. Silver Oak says it has over 200 games on mobile, including Storm Lords, T-Rex II and Cash Bandits 3. Third-party reviewers list no live dealer tables at either casino on this page, and lobbies change over time. Check the casino's mobile lobby for a specific game, or see our California slots page.
Are sweepstakes casino apps allowed in California?
No. AB 831 banned dual-currency sweepstakes casinos in California from January 1, 2026, and that applies whether you play in a browser or an app. Most major brands now list California as excluded in their own rules or in third-party trackers, and an app on your phone doesn't change that. Our sweepstakes casinos in California page lists each brand's status.
Is it safe to verify my casino account from my phone?
It can be, if you send documents only through the casino's official site or email and use a secure connection rather than public Wi-Fi. Silver Oak's terms ask for photo ID, card images, a selfie with ID and a recent utility bill. Delete copies from shared folders afterward. See why casinos ask for documents.
How do I block casino sites on my phone in California?
Install a blocking app such as Gamban, which costs $6.99 a month or $41.99 a year after a seven-day free trial and runs on iPhone and Android. Combine it with the casino's own self-exclusion and your phone's screen-time limits, and use California's Office of Problem Gambling for local support. Free national help is at 1-800-MY-RESET (1-800-697-3738). Our Gamban guide walks through setup.
Why does an offshore casino tell me to add a home-screen shortcut?
Because it has no app. SlotoCash's support page, for example, says no app or software is required and suggests a home-screen shortcut instead. Save the shortcut only from the casino's official domain, since unofficial mirror sites copy casino names. Our instant play vs download guide explains the difference between browser and installed casinos.
Can I play mobile casino games on Android in California?
Yes, offshore casinos run in Android phone browsers, but none of them is licensed by California. Silver Oak's own mobile page lists Android, iPhone and tablet play, and third-party reviewers say Planet 7 and Slot Madness also run in Android browsers without an app. Using Chrome on Android instead of a laptop doesn't change the legal position: the state licenses no online casino, so there's no state regulator behind the site. Our playing on Android guide covers setup and security.
What is the minimum deposit at a mobile casino from California?
It's as low as $5 at Planet 7 by Bitcoin Lightning, according to third-party reviews, and $30 at Silver Oak. Silver Oak's own banking page lists crypto deposits from $30 with no fee, and card deposits from $30 to $1,000 with fees of 3% to 10%, so a $100 card deposit could cost up to $10 extra. Planet 7's card minimum is reported at $30. Bonus offers often need more than the cashier minimum, so read the terms. See casino minimum deposits.
Why does my card get declined at mobile casinos in California?
Card payments to gambling merchants carry merchant code 7995, and many US issuers block that code, so the decline usually comes from your bank rather than the phone. It happens the same way in a mobile browser as on a desktop. Some banks also treat credit card gambling as a cash advance with fees. That's why offshore cashiers push Bitcoin and other coins instead. Don't use someone else's card to get around it. Read why was my credit card declined at a casino.
How do I withdraw from a mobile casino in California?
You use the same cashier as on desktop: verify your identity, pick a payout method and wait out the casino's review. Silver Oak's banking page lists Bitcoin withdrawals from $50, and its terms describe a 7–10 business-day review followed by 7–10 days for payment, with withdrawals blocked until ID checks are complete. Photograph your documents in good light and send them before you request money. Our guide on how to withdraw from an online casino covers each step.
What age do California mobile casinos require?
No California casino age applies to offshore mobile sites, because the state licenses none; each casino sets its own minimum in its terms. Silver Oak's terms say 21, while SlotoCash's say 18. The California Lottery's minimum is 18, and no state-set online casino age exists. Never sign up with false details to get past an age check, since that voids winnings and breaks the terms. Our gambling age by state page compares ages for other products and states.
Have regulators acted against the mobile casinos shown for California?
Yes, in Michigan rather than California. The Michigan Gaming Control Board named both Silver Oak and Planet 7 in cease-and-desist letters on April 9, 2025, calling the recipients illegal offshore operators. The sources available record no California action against either brand, but California licenses no online casino, so neither has state approval. Those letters order operators to stop serving Michigan; they aren't actions against players. Our cease-and-desist letters page tracks every release we cover.
