Put a barrier on the device

The phone or laptop in your hand is usually the shortest route to an online casino, so it is a natural place for the first barrier. Each of the main operating systems can stop chosen sites from loading, and dedicated blocking tools go further. None of them is perfect, so the limits sit right alongside the steps.

Why the device comes first

Most online gambling now happens on phones. A barrier set on the handset or laptop you actually use meets the urge exactly where it appears — in the browser tab or app store you open without thinking. Built-in controls cost nothing and need no extra software, so they are a reasonable first step even while you consider anything more. Their weakness is equally simple: each one protects only the device it lives on, and whoever knows the passcode can switch it off.

Screen Time on iPhone, iPad and Mac

Apple's Screen Time includes content restrictions that stop Safari, and apps that use Apple's built-in web view, from opening addresses you list. Menu names have shifted between versions of iOS and macOS, so treat these steps as a guide to where to look rather than exact wording.

1. Open Settings and tap Screen Time. On a Mac, open System Settings and choose Screen Time.
2. Choose Content & Privacy Restrictions and switch it on.
3. Find the web content option (usually under Content Restrictions or App Store, Media, Web & Games) and select Limit Adult Websites.
4. Under Never Allow, add the addresses of gambling sites you have used.
5. Set a Screen Time passcode that differs from your unlock code — ideally chosen and kept by someone you trust.
6. In the same restrictions, consider blocking app installation so new gambling apps cannot be added quietly.

Screen Time blocks some adult content by category, but it does not recognise gambling sites by itself. The Never Allow list needs topping up whenever a new name appears.

Windows: Family Safety and the hosts file

Microsoft Family Safety lets an organiser account set web filters for a member account, including a list of blocked sites in Microsoft Edge. It works best when a trusted person holds the organiser account. Because its filtering is built around Edge, other browsers usually need to be blocked or removed for the filter to mean much.

The hosts file is an older, plainer tool found on Windows, macOS and Linux. It is a short text file the computer checks before asking the wider internet where an address lives. Pointing a gambling address at 0.0.0.0 sends the request nowhere.

1. On Windows, search for Notepad, right-click it and choose Run as administrator. On a Mac, open Terminal and type sudo nano /etc/hosts.
2. On Windows, open C:\Windows\System32\drivers\etc\hosts, choosing All files in the file-type menu so it appears.
3. Add one line per address, for example 0.0.0.0 casino-site.example and a second line for the www version.
4. Save the file, then clear cached addresses with ipconfig /flushdns on Windows, or restart the Mac.
5. Type the address into each browser and confirm it fails to load.

Android and dedicated blocking tools

Android has no built-in blocked-sites list for an adult's own account. Google Family Link adds supervision, but it is designed for children's and teenagers' accounts. For adults, the usual routes are Private DNS with a filtering service, covered under network layers, or a dedicated blocker.

Two dedicated tools are widely mentioned by UK support services. Gamban is a paid subscription app that blocks a large, maintained list of gambling sites and apps across phones, tablets and computers, and is built to be awkward to uninstall. BetBlocker is a free tool run by a charity, which lets you choose a period during which the block cannot be lifted. Both update their lists centrally, which solves the hosts file's biggest weakness: new sites. Check each tool's own website for supported devices and how removal works.

Checks before you rely on it

• The block covers every browser installed, not only the default one.
• Private or incognito windows are blocked as well.
• Gambling apps already on the device have been deleted, not just moved off the home screen.
• Someone you trust holds the passcode, or it is stored somewhere deliberately inconvenient.
• A test address still fails to load after a restart.

What a device barrier will not do

• It does nothing on a second phone, a work laptop or a borrowed tablet.
• Anyone with the passcode or administrator rights can remove it.
• Hand-made lists miss new or renamed sites.
• It does not touch gambling by phone, in shops or in venues.

Those gaps are why other layers exist: a network filter for the whole household, account controls such as GAMSTOP, and people who understand.
