Found a gambling site that gets through? Report it and we add it in the next update. You can also block it yourself from the extension right away.
How it works
Setup takes under a minute. After that, GambleGuard works in the background without anything to manage.
Add GambleGuard to Chrome
Install it from the Chrome Web Store and pin it to your toolbar. There is no account to create and nothing to configure.
Gambling sites are blocked automatically
When you open a known gambling site, or a page full of betting language, GambleGuard shows a calm GambleGuard page instead, then takes you to Google after five seconds. Press Stay to use the breathing exercise, see your progress, or call a free helpline.
Add your own sites
Block any extra site in two clicks. Your list stays on your computer.
See your progress
Open the extension to see how many gambling sites it has blocked, your days protected, and an estimate of the money you kept.
Your browsing history never leaves your computer.
Using a blocker should not mean handing someone a record of your worst moments. GambleGuard is built so there is nothing to hand over.
- Checks happen in ChromeEvery site check and page scan runs locally. Nothing is sent to a server.
- No account, no profileWe never ask who you are, so there is no profile to leak, sell, or subpoena.
- Your log is yoursYour block log and stats live in Chrome storage. Export them or erase them any time. Read the privacy policy.

What GambleGuard adds when you’re using Chrome
- Catches new sites, not just listed ones. Pages are scanned for gambling language, so sites missing from the list are often blocked too.
- Help in the moment. Every block shows a calm page with a one-minute breathing exercise and free helplines.
- Progress you can see. Sites blocked, days protected, and an estimate of the money you kept.
- Nothing leaves your computer. Every check runs inside Chrome, with no servers involved.
The strongest setup is layered: a device-wide blocker such as BetBlocker or Gamban, GambleGuard in Chrome, and a gambling block from your bank. Our guide to blocking gambling sites walks through each step.

Frequently asked questions
Is GambleGuard really free?
Yes. GambleGuard is completely free, with no subscription, no ads, and no account. It is a small project built to make blocking gambling sites easy for anyone.
What does GambleGuard block?
It blocks online casinos, sportsbooks, poker sites, crypto casinos, lottery sites, and CS2 and Rust skin-gambling sites. It uses a built-in list of known gambling domains, scans pages for gambling language to catch sites that are not on the list, and blocks any extra sites you add yourself.
Does GambleGuard collect my browsing data?
No. Every check happens inside your browser. GambleGuard never sends your history, the pages you visit, or your block log to us or anyone else. Your stats and custom block list are stored only in Chrome on your computer.
Can I pause or unblock a site?
No, and that is deliberate. GambleGuard has no pause button or allow list, so there is no quick way around it during an urge. To stop it you would need to disable or remove the extension in Chrome settings, which adds time to think.
Does it work on my phone?
No. Chrome on Android and iPhone does not support extensions. For phones, use Screen Time on iPhone or a device-wide blocker. Our guide on how to block gambling sites covers each option.
Will it slow down my browsing?
No noticeable slowdown. The domain check takes a fraction of a millisecond, and the page scan runs once, a second after a page loads, only on sites that are not on the built-in list.
A site is blocked by mistake. What should I do?
Use the contact form on our support page and tell us the address. Because GambleGuard has no allow list, we fix false positives in the extension itself so everyone benefits.
Is GambleGuard a treatment for gambling addiction?
No. GambleGuard is a barrier that supports your decision to stop. Recovery usually works best with support from people too. The National Problem Gambling Helpline at 1-800-MY-RESET is free, confidential, and open 24/7.
