The online gambling blocker that works on your terms.
Online Gambling Blocker is a free browser extension that stops online casinos, sportsbooks and the flood of unregulated, offshore and scam gambling sites — before the page ever loads. No account. No tracking. And hard to switch off when you need it that way.
Built for the people other tools forget.
Most blockers are either expensive, leaky with your data, or trivially switched off in a weak moment. We fixed the four things that actually matter.
Completely free
No paywall, no premium tier, no card. Protecting yourself should never cost money.
Privacy-first
No sign-up, no analytics, nothing leaves your device. The blocklist runs in your browser.
Hard to disable
Turning protection off takes a deliberate pause — not one impulsive click — so 2 a.m. relapses are harder.
Works everywhere
Chrome, Edge, Brave and Firefox. One list covers every gambling site you try to open.
Three steps. Then the casino simply never opens.
Add it to your browser
Download it and load it into your browser in about a minute — no account to create, nothing to configure to be protected.
Every site gets checked
Each address is matched against a built-in blocklist plus on-device smart detection of casino and betting patterns.
Gambling stops at the door
Instead of the casino you get a calm block screen and a link to support — not a flashing invitation to play.
Block everything — or just the lawless side.
By default we block all online gambling. But you decide where the line sits. Trust one licensed operator in your country and want to shut out every unregulated, offshore and scam site instead? Add it to your personal allowlist.
You know your own jurisdiction better than any global list ever could — so the choice stays with you, not with us.
How we stack up against the tools people already know.
BetBlocker and Gamban are good, genuine tools. Here's simply where we differ — see the full comparison.
Online Gambling Blocker, answered.
The things people ask most before they install. Still unsure? Every claim here is explained in plain language across our guides.
Is Online Gambling Blocker really free?
Yes — completely. There's no paywall, no premium tier and no card to enter, now or later. It's a non-commercial project with no ads and no casino affiliate links, so nothing about it depends on you gambling. You just download the extension and load it into your browser.
How does the blocker stop gambling sites?
Every address you open is checked against a built-in list of known casinos, sportsbooks and betting sites, plus on-device smart detection that recognises gambling sites by their tell-tale patterns — so new and offshore sites can be caught even before they reach any list. When a site matches, you get a calm block screen instead of the casino.
Can I block only unregulated or offshore casinos?
By default the blocker stops all online gambling, but you decide where the line sits. If you trust one licensed operator in your country, add it to your personal allowlist and the gambling blocker will shut out every unregulated, offshore and scam site instead. You know your own jurisdiction better than any global list could.
Does it work in Chrome, Edge and Brave?
Yes. Online Gambling Blocker is a Chrome-based extension, so it installs the same way in Google Chrome, Microsoft Edge and Brave. Our install guide walks through it step by step — it takes about a minute and needs no account.
Can I just switch it off in a weak moment?
Not in one impulsive click. Turning protection off takes a deliberate pause rather than a single tap, which is exactly the point — that bit of friction is what makes a 2 a.m. relapse harder. A blocker is one tool, not the whole answer, so we also link to free confidential support throughout the site.
Does it track my browsing?
No. There's no account, no analytics and no tracking of any kind. The blocklist and detection run entirely on your device, and your browsing is never sent anywhere. You can read exactly how this works in our privacy policy.
Take the next site off the table.
Free, private, and on in under a minute. The hardest part is the first click — we made it the only one.
Free · Works in Chrome, Edge & Brave · No account, no cost.
