How to Block Gambling Sites on Chrome (2026 Guide)

On a computer: open Chrome Web Store. Android: use the phone instructions.

1. In the Chrome Web Store, choose a site blocker. Check its publisher and permissions, then select Add to Chrome.
2. Open the extension from the toolbar. Add your gambling domains to its blocklist and turn it on.
3. Try each address in Chrome without signing in or placing a bet. Check that access is blocked.
4. Open Extensions > Manage extensions > Details for the blocker. Turn on Allow in Incognito and test there too.

Check the extension's plan limits before installing. Its blocklist menu will vary. Chrome's own site settings have no personal website blocklist, and an extension can be disabled or removed. Extensions cannot be installed in mobile Chrome. Google's extension instructions.

For coverage outside Chrome: add a DNS or router filter or a device-level layer.

Choose the Right Blocking Layer

• Chrome extension: Fast to set up on a computer and useful for named sites. It can be disabled or removed by someone who controls the browser.
• Chrome settings: Useful for removing notifications, pop-ups, saved passwords, and shortcuts. They do not block a normal website.
• DNS or router filter: Can cover devices that use the filtered network or resolver. Mobile data, another Wi-Fi network, custom Secure DNS, Private DNS, or a VPN may take a different path.
• Device-level blocker: Can cover more than one browser. Coverage and removal protection depend on the operating system and product.

For a stronger setup, combine at least one browser layer with one layer outside Chrome.

1. Remove the Easy Routes Back

Before adding a block:

1. Delete gambling bookmarks.
2. Remove saved gambling passwords from Google Password Manager.
3. Remove gambling sites from the list allowed to send notifications.
4. Clear gambling-related autofill entries and saved payment methods where safe.
5. Sign out of gambling accounts and use the operator's account-closure or self-exclusion controls.

Removing these shortcuts will not block a site, but it reduces automatic prompts and one-click access.

2. Use a Site-Blocking Extension on a Computer

Chrome Web Store extensions can block a list of domains on desktop Chrome. Google states that extensions cannot be installed on a mobile device, including when Chrome is set to desktop mode. Before installing one on a computer:

• Review its publisher, update history, privacy practices, and requested permissions.
• Prefer an extension that explains where its blocklist is stored and whether it sends browsing data to a server.
• Add the exact domains you use, including regional or product-specific subdomains.
• Test the block in a normal Chrome window.
• Open More > Extensions > Manage extensions, select Details, and turn on Allow in Incognito for the blocker. Test an Incognito window separately.

An extension is not a hard lock when you control the browser. Chrome lets users disable or remove extensions. If possible, let a trusted person control the relevant device or browser administration settings.

3. Reduce Notifications, Pop-Ups, and Redirects

Chrome settings can reduce common gambling prompts:

1. Open Settings > Privacy and security > Site settings.
2. Review Notifications and remove gambling sites from the allowed list.
3. Set notification requests to the more restrictive option.
4. Review Pop-ups and redirects and keep them blocked.
5. Remove gambling sites from any custom allow lists.

These settings reduce exposure. They do not block ordinary navigation to a gambling website.

4. Add DNS or Router Filtering

Network-level filtering works outside a single Chrome profile and can cover other browsers and devices on the same network.

Choose a provider that explicitly supports a gambling category or a custom denylist. Generic malware, adult-content, or family filters do not always include gambling. Follow the provider's router or device instructions, then test the domains you are trying to block.

Network filtering has limits:

• It may only apply on your home Wi-Fi.
• Mobile data and other Wi-Fi networks may bypass a router setting.
• A user with device or router access may be able to change the DNS configuration.
• Chrome can use a custom Secure DNS provider instead of the network's ordinary resolver.
• Domain filtering may not block content served from a shared platform or app.

After changing DNS, open Chrome > Settings > Privacy and security > Security and review Use secure DNS. Test the gambling domains you want to stop. A custom provider selected in Chrome can behave differently from the DNS configured on the router.

For router setup and checks across other networks and devices, follow the WiFi gambling-blocking guide.

5. Add a Device-Level Blocking Layer

A device-level blocker can cover browsers other than Chrome and may maintain a broader gambling-domain list. Coverage and removal protection vary by operating system.

See Detachr's quit gambling app for the app overview and device selector, or read about gambling blocking. Pair your chosen blocker with browser cleanup, self-exclusion, and financial barriers. Keep the browser and network controls above in place while you arrange device-level protection.

Recommended Layered Setup

1. Remove bookmarks, saved logins, payment shortcuts, and notifications.
2. Add and test a site-blocking extension.
3. Add a DNS or router filter that explicitly covers gambling.
4. Use a device-level blocker where supported.
5. Use self-exclusion and close your gambling accounts.
6. Use the help directory when gambling is affecting money, relationships, work, housing, or safety.
