How to block gambling sites in Chrome

The most reliable way to keep online casinos and sportsbooks out of Chrome is a dedicated blocker that checks every page before it loads. Here's the free one-click option, plus the built-in settings and DNS backstops you can stack on top of it.

A blocker stops a gambling site at the browser door — before the page ever renders.

Chrome doesn't ship with a gambling filter of its own, but it's one of the easiest browsers to protect because it runs extensions. The approach below works whether you're blocking gambling for yourself, setting things up for a family member, or just want the temptation gone for good. Start with the extension, then add the device-level and network layers so the block holds even on a hard day.

The simplest way: our free Chrome extension

OnlineGamblingBlocker is a free, privacy-first gambling blocker Chrome extension. It checks each address against a built-in blocklist of casinos, sportsbooks and unregulated offshore sites, and stops them before the page loads — so instead of a flashing casino lobby you get a calm block screen. There's no account, no sign-up and nothing leaves your device.

  1. Open the Chrome Web Store and search for OnlineGamblingBlocker (or use the Add to Chrome button on this site).
  2. Click Add to Chrome, then confirm Add extension. It installs in a few seconds.
  3. Pin it — click the puzzle-piece icon in Chrome's toolbar and pin the shield so it's always one click away.

That's it. You're protected immediately, with the default list blocking all online gambling. No further setup is needed to be safe.

The popup, the allowlist and the pause

Click the toolbar icon and a small popup shows what's active. From there you can manage your allowlist — the heart of the "your terms" idea. By default everything gambling is blocked, but if you trust one licensed operator in your own country, you can add it and keep every unregulated and scam site shut out. You know your jurisdiction better than any global list could, so the line stays where you put it.

Turning the blocker off is deliberately not instant. Pausing or disabling protection runs through a short friction step rather than a single toggle, so a 2 a.m. impulse meets a speed bump instead of an open door. That small delay is often enough to let the urge pass.

Also covers Edge and Brave

Edge and Brave are built on the same Chromium engine as Chrome, so the same extension installs and works the same way on both. One blocker, three browsers — see the comparison of blockers for the full picture.

Manual options in Chrome without an extension

If you'd rather not install anything, Chrome and your Google account offer a few built-in controls. They're more limited than a dedicated blocker, but they can help — especially when combined.

Block individual sites in Chrome settings

Chrome's Site settings (Settings → Privacy and security → Site settings) let you control permissions and clear data per site, and you can block notifications from a gambling site so it can't ping you. This won't stop you from opening a casino, but it does cut off the re-engagement nudges. For full address blocking you'll want one of the stronger layers below.

Supervised profiles and Family Link

Google's Family Link lets a parent or guardian manage a child's or supervised account, including filtering websites and approving what Chrome can open. For an adult setting up accountability, a supervised Google profile where someone else holds the settings can make gambling sites much harder to reach on a whim.

SafeSearch and content filters

Turning on Google SafeSearch and locking it within a managed account reduces how easily explicit and some adult-content results surface. It's not a gambling-specific filter, so treat it as a minor helper rather than a real block.

The honest limit

Built-in Chrome settings can be changed back by anyone who knows where to look. They're worth using, but they work best alongside an extension and a network-level block — not on their own.

DNS-level blocking as a backstop

An extension protects Chrome; a DNS filter protects the whole device and any browser on it. DNS is the system that turns a web address into a number — so if your DNS provider refuses to look up gambling domains, the sites can't load at all, even outside Chrome. Several free and paid DNS services offer a gambling or "high-risk" category you can switch on.

Set the filtering DNS at the router level and it covers every device on your home network at once. Because it sits below the browser, it's a strong second layer that catches anything an extension might miss — and it's hard to bypass without changing system settings.

Make it hard to undo

The point of a block isn't just to set it up — it's to keep it in place when motivation dips. A few habits make that far more likely:

  1. Stack the layers. Extension plus DNS plus any device controls means no single switch removes your protection.
  2. Hand over the keys. Let a trusted person hold a Family Link or router password, or the account credentials, so undoing the block isn't a private, solo decision.
  3. Use the friction. Keep the extension's pause delay on. The wait is the feature.
  4. Lock the network settings. Protect your router admin page with a password you don't keep handy, so DNS changes aren't a one-click affair.
A tool, not the whole answer

Blocking access removes the easy path, which genuinely helps. But if you're struggling to stop, free and confidential support is available 24/7 — reach a gambling helpline in your country, and read our guide to stopping gambling.

FAQ

Does Chrome have a gambling blocker?

Not built in. Chrome has site settings and permission controls, but no dedicated gambling filter. To block gambling sites in Chrome you add a blocker — most simply, a free extension like ours — or use a DNS filter that covers the whole device.

Is there a free gambling blocker for Chrome?

Yes. OnlineGamblingBlocker is free, with no account, no premium tier and no tracking. It blocks online casinos, sportsbooks and unregulated sites before they load. You can install it from the Chrome Web Store in under a minute.

Does it work on Edge and Brave?

Yes. Edge and Brave are built on the same Chromium engine as Chrome, so the extension installs and behaves the same on all three. One blocklist covers each of them.

Can I still allow one site I trust?

Yes — that's what the allowlist is for. By default all gambling is blocked, but if you trust one licensed operator in your country, you can add it to your personal allowlist while every other gambling and scam site stays blocked. The choice of where the line sits is yours.
