How to Block Gambling Sites in Google Chrome (Protect Your Browsing) Easily 2026
By Impran M NLast checked against official docs
Chrome doesn't have a built-in "block gambling sites" switch, which is why most people reach for a dedicated blocking extension instead of digging through settings that don't cover this case. A proper site blocker treats gambling as a whole category rather than a list you maintain by hand, so you're not chasing down every new casino or betting domain that pops up. This guide follows the real setup: finding an extension built for category blocking, turning on Gambling specifically, and locking the settings down so the block can't just be switched off later.
01Understand what you're actually blocking
A quick search for "gambling websites" shows the scale of the problem: casino platforms, sports betting sites, and forums built around online gambling appear by the dozen, with new ones surfacing constantly. This is worth seeing directly, because it explains why a static list of blocked URLs falls behind fast.
You need something that blocks the category, not today's list of offenders. It's also a reminder that gambling sites don't only mean obvious casino brands; betting-focused forums and affiliate review sites promoting them count too, and a category blocker is the practical way to catch that whole ecosystem.

02Open the Chrome Web Store and search for a blocking extension
Go to the Chrome Web Store and search using a general term like "website blocker" instead of a brand name at first. Chrome's search suggestions surface several relevant extensions as you type, including tools built for blocking distracting or harmful categories of sites, alongside unrelated results like ad blockers and productivity tools. Scan the list rather than clicking the first result, and check install counts and star ratings before choosing one; a blocking extension with a small install base is more likely to be abandoned or unreliable than one with a long track record.

03Install an extension built for category blocking
Look for an extension such as BlockSite, built around blocking whole categories of distracting or harmful sites instead of one URL at a time. Click Add to Chrome and confirm the permissions it requests; a site blocker needs to read the URLs you visit in order to function, which is normal for this category of extension.
Scroll through the listing's preview images before installing. They typically show the actual block-list and category screens you'll be working with, which is a useful preview of the setup before committing.

04Turn on the Gambling category
Open the extension after installing it and go to its Block Sites section, then choose Add to Block List. Instead of typing individual URLs, switch to the Categories view, where Gambling appears alongside categories like Adult, Social, News, Sports, and Shopping, each with its own toggle.
Turning on Gambling blocks the entire category at once, covering casino sites, betting platforms, and gambling forums without you needing to know their names in advance. On BlockSite's current plans, category blocking is a Premium feature, so this step may prompt an upgrade if you're on the free tier. You don't have to lock every category shown here; Sports and Shopping, for instance, can stay off if gambling is your only concern.

05Add specific sites for anything the category misses, then lock the settings
Category blocking catches most gambling traffic, but if a specific site slips through, add it under Websites to Block on the same screen; a broad category lock plus a short manual list for edge cases covers more ground than either alone. Then, if the goal is a block that can't be casually switched off, for a shared device or a family member, turn on password protection under the extension's settings, also a Premium feature. Choose a password different from ones the other person on the device already knows, and store it somewhere separate from the device if the point is limiting your own access.
06Check that mobile Chrome is covered too
A block list set up on desktop Chrome doesn't automatically extend to a phone. Chrome extensions don't sync to the Android or iOS versions of the browser, so a comparable mobile app or blocker needs installing separately. If gambling access from a phone is part of what you're trying to prevent, treat it as its own setup step instead of assuming the desktop configuration has you covered.
When it doesn't work
Turning on the Gambling category prompts an upgrade screen
Why: Category blocking sits behind BlockSite's paid Premium tier; the free plan supports only a short manual list of individually entered sites.
Fix: Either upgrade, or fall back to adding known gambling domains one at a time under Websites to Block, accepting that new sites won't be caught automatically.
A gambling site loads despite the category being blocked
Why: The category filter catches known and listed domains; a brand-new site can exist before it's classified.
Fix: Add the specific domain manually under Websites to Block as a backstop while the category list catches up.
The block list gets switched off from someone else's device
Why: Password protection wasn't turned on, so the extension's settings, including the block list, can be edited by anyone using the browser.
Fix: Enable password protection in the extension's settings and use a password the other person doesn't already know.
Frequently asked questions
Is blocking gambling sites in Chrome free?
Installing a blocker like BlockSite is free, and a short manual list of specific sites is free to maintain. Blocking the whole Gambling category automatically, and password-protecting the settings, are Premium features on BlockSite's current plans.
Can this help with parental controls?
Yes, particularly combined with password protection, so the block list can't be disabled without the parent's password.
Do I need to keep updating the block list manually?
No for the category itself; new gambling sites that get classified into the Gambling category are covered automatically. You only add individual URLs by hand for edge cases the category doesn't catch yet.
Does Chrome have a built-in way to block gambling sites without an extension?
No. Chrome's native settings don't include a gambling-category filter, which is why a dedicated blocking extension is the practical way to cover this.
Does blocking gambling sites on desktop Chrome also block them on my phone?
No. Chrome extensions don't carry over to Android or iOS Chrome, so mobile needs a separate app or blocker if that's part of what you're trying to prevent.
Sources and last check
Click path and screens come from an installation walkthrough. The claim that category blocking and password protection are free features was re-checked in September 2026 and corrected: on BlockSite's current plans, both sit behind the paid Premium tier, with the free plan limited to a short manually-entered block list. Exact Chrome Web Store install counts and star ratings returned inconsistent figures across fetches, so this version doesn't state a specific number.
