Gambling Blocking Software: How It Works and Its Limits

Most gambling now happens on phones and laptops. That makes it constantly available — but it also means a technical barrier on the device itself can be one of the most effective ways to stop. Blocking software prevents your devices from reaching gambling websites and apps, regardless of whether those operators are licensed in your country.

Why blocking software matters

National self-exclusion schemes are powerful, but they only bind licensed operators. Unlicensed offshore sites, which do not check national registers, remain reachable — and some deliberately target people who have self-excluded. A device-level blocker closes much of that gap.

Blockers also help with the speed of urges. When an urge to gamble arrives, it can peak within minutes. A barrier that stops you reaching a site at that moment can carry you through to the point where the urge fades.

How it works

Gambling blockers use one or more of these methods:

• Domain blocklists — a regularly updated list of known gambling websites that the device refuses to load.
• App blocking — preventing gambling apps from being installed or opened.
• DNS or network filtering — routing web requests through a filter that blocks gambling categories.
• Keyword or category detection — catching new or unknown sites based on content.

Good blockers update their lists frequently, because new gambling domains appear constantly.

Well-known tools

Several tools are widely used by support services and people in recovery. Among the best known are Gamban, BetBlocker and GamBlock. They differ in price, supported devices, how they handle uninstalling and how their blocklists are maintained. Some are free, some are paid, and in some countries support organisations can arrange free access. We do not recommend one over another; a helpline in your country can tell you what is available locally, and our help directory lists services by country.

Other options include:

• Built-in parental controls and screen-time settings on phones and computers, which can restrict gambling content and app installs.
• Router or network-level filters that apply to every device on your home Wi-Fi.
• Family-safety DNS services that block gambling categories.

Choosing a blocker: what to look for

Feature	Why it matters
Works on all your devices	Gambling moves to whichever device is unprotected
Blocks apps as well as websites	Many people gamble mainly through apps
Covers offshore and new sites	The main gap left by self-exclusion
Hard to remove on impulse	Urges are short; delays defeat them
Fixed or minimum blocking period	Mirrors the commitment of self-exclusion
Regular updates	New domains appear constantly

Making it harder to undo

The value of a blocker comes from friction. Ways to increase it:

• Choose the longest blocking period you are comfortable with.
• Ask someone you trust to hold the password for parental controls or the router.
• Turn on app-store restrictions so new gambling apps cannot be installed.
• Protect every device, including old phones, tablets and games consoles with browsers.
• Avoid installing VPNs or alternative browsers that could bypass filters.

Limitations to be honest about

No blocker is perfect:

• Determined users can sometimes find workarounds, such as other devices, VPNs or new domains not yet listed.
• Blockers do not stop in-person gambling, lottery tickets or betting shops.
• They do not block marketing sent by email or text, so unsubscribe separately.
• They do not address the reasons someone gambles.

This is why blocking software works best as one layer among several:

1. Self-exclusion through your national register — see /self-exclusion/.
2. Device-level blocking software.
3. A bank gambling block to stop payments.
4. Support from a helpline, counsellor or peer group.

Setting up: a practical checklist

1. List every device you could gamble on: phones, tablets, laptops, work-from-home computers, smart TVs and games consoles with browsers.
2. Install your chosen blocker on each one, following the provider’s instructions for that operating system.
3. Remove existing gambling apps and log out of gambling accounts in every browser.
4. Turn on app-store restrictions so new gambling apps cannot be downloaded.
5. Check the blocking period and set it to the longest you are comfortable with.
6. Add a network filter on your home router for an extra layer, if you can.
7. Write down the date your blocking period ends and decide in advance whether you will renew.

Blocking marketing as well

Gambling marketing can be a powerful trigger, and software alone will not stop it. Alongside a blocker:

• unsubscribe from every gambling email list and reply “STOP” to marketing texts;
• unfollow or mute betting brands, tipsters and gambling streamers on social media;
• use social platforms’ advertising preferences to reduce gambling adverts where that option exists; and
• ask any operator you have self-excluded from to confirm that marketing has stopped.

Supporting someone else

If you are a family member, you may want to suggest blocking software. It is most effective when the person gambling agrees to it and chooses it themselves; secretly installing software on another adult’s device can damage trust and may not be lawful. Our article on supporting a partner or family member offers more guidance.

If you get around it

If you find yourself bypassing a blocker, treat it as information rather than failure. Ask: what was happening just before? Was I tired, stressed, bored, drinking, or had I just been paid? Our guide to relapse prevention and urges covers practical strategies, and talking to a support service can help you strengthen your plan.
