How to Block Gambling and Betting Sites on Chrome (2026)

To block gambling or betting sites on Chrome on a computer, remove saved shortcuts, add a carefully chosen site-blocking extension, and then add a device or DNS layer outside the browser. Chrome does not include a personal website blocklist. Its built-in settings can reduce notifications and pop-ups, but they do not prevent ordinary navigation to a gambling site.

Chrome on Android needs a different setup because mobile Chrome cannot install extensions, even in desktop mode. Use Android site timers, Private DNS, or a device-level blocker there.

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.
• Check Incognito separately. Extensions are not automatically allowed in Incognito.

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.

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.

Detachr's gambling blocker overview describes its current mobile blocking support. Use it alongside browser cleanup, self-exclusion, and financial barriers.

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 gambling accounts.
6. Use the help directory when gambling is affecting money, relationships, work, housing, or safety.

Also protect the devices around Chrome. See how to block gambling apps on iPhone and how to block gambling apps on Android.
