How do I block gaming websites on Chrome for free?

Install a free blocking extension, add the gaming domains you want gone, and start a block. With the Focuh Chrome extension you add sites like crazygames.com, poki.com, and store.steampowered.com to your blocklist, then start a focus challenge so they stay blocked. No account or payment is needed. The whole setup takes about a minute, and the extension blocks those tabs in Chrome until your session ends.

What counts as a gaming website to block?

Three groups, usually. Browser-game portals like CrazyGames, Poki, Coolmath Games, and Miniclip, where you play instantly in a tab. Game stores and launchers' web pages, like store.steampowered.com or the Epic Games Store. And gaming-adjacent rabbit holes — wikis, Twitch, gaming subreddits, and YouTube gaming channels. Block whichever group actually pulls you in; for most people it's the instant-play browser portals, since those need no install.

Can a Chrome extension block game apps like Steam or Roblox?

No. A Chrome extension only controls tabs inside Chrome. It can block the Steam or Roblox website, but it can't stop the installed Steam, Roblox, or Epic Games desktop app from opening, because those run outside the browser. To block actual game applications you need an operating-system tool. On macOS, the free Focuh app blocks both websites and native apps during a focus session.

How do I block browser games on Chrome?

Browser games are the easiest to block because they live entirely in a tab. Add the portal domains to a free blocker — crazygames.com, poki.com, coolmathgames.com, miniclip.com, addictinggames.com — and the games stop loading. Because these sites need no install, blocking the domain fully cuts off access in Chrome, unlike native game apps that keep working even when their website is blocked.

Can I block gaming sites on Chrome only during work hours?

Yes. Use an extension with scheduling, such as LeechBlock NG, and set a blockset of gaming domains active from your start time to your end time on weekdays. The games load normally in the evening. If you'd rather tie blocking to focus sessions than to fixed hours, the Focuh extension blocks your gaming list for the length of a challenge you start, which suits people who study or work in defined blocks.

Will blocking gaming websites slow down Chrome?

No. A well-built blocker only checks the hostname of a tab against your local list when it navigates, which is trivial work for the browser. You won't notice any slowdown from adding gaming domains. Heavier extensions that scan page content or sync to a server can add overhead, but lightweight blockers like Focuh and LeechBlock NG don't do that, so your browsing stays fast.

Can someone bypass a blocked gaming site on Chrome?

Yes. Any Chrome extension can be turned off from chrome://extensions, and someone can also switch to another browser or open a game's desktop app. A browser block is meant to interrupt the reflex to open a game, not to be unbreakable. For a block that's genuinely hard to lift mid-session, use the Focuh Mac app, which blocks at the system level and is much harder to disable than an extension.

How do I block gaming sites on my kid's Chrome?

For a child's device, a Chrome extension is easy for them to disable, so it's the weakest option. Google's Family Link offers parental supervision, and on macOS, Screen Time can restrict sites in Safari with a passcode. For broad, harder-to-remove coverage across browsers and apps, a system-level tool on the device works better than any single Chrome extension, which a curious kid can switch off in seconds.

How to Block Gaming Websites on Chrome (Free, 2026)

June 16, 202610 min readFocuh

Gaming sites are built to keep you in the tab — instant browser games, store pages teasing the next sale, wikis that turn a quick question into an hour. Here's how to block gaming websites on Chrome for free: install a blocking extension, add the gaming domains that pull you in, and start a block. Below are the methods that work, which gaming sites are worth blocking, and the one thing a Chrome extension can't do — block the game apps themselves.

Which gaming websites should you block?

Before installing anything, decide what's actually costing you time. "Gaming websites" covers three different traps:

Browser-game portals — CrazyGames, Poki, Coolmath Games, Miniclip, Addicting Games. You play instantly in a tab, no install, which makes them the most common time sink.
Game stores and launchers (web) — store.steampowered.com, the Epic Games Store, Itch.io. You don't play here, but browsing sales and wishlists eats time and leads to installs.
Gaming rabbit holes — wikis, Twitch streams, gaming subreddits, and YouTube gaming channels. Technically "research," usually procrastination.

Block the group that actually grabs you. For most people it's the instant-play portals, because they need nothing installed and load in one click.

Method 1: Focuh extension (free, no account)

The free Focuh Chrome extension is built for exactly this — blocking a list of distracting sites for the length of a focus challenge.

Install Focuh from the Chrome Web Store.
Add your gaming domains to the blocklist: crazygames.com, poki.com, coolmathgames.com, store.steampowered.com, and any others that get you.
Start a challenge — 30, 91, or 180 days, or a custom length.

Those sites stay blocked in Chrome for the whole challenge. Focuh has no account, no telemetry, and no cap on how many domains you block, and everything stays in local Chrome storage. It's the simplest option if your goal is "keep me off these for a stretch" rather than a complex daily schedule.

Method 2: LeechBlock NG (scheduled gaming blocks)

If you only want gaming sites blocked during work or study hours, LeechBlock NG is the free, open-source tool for it. Create a blockset, add your gaming domains, then set active hours and days — say, blocked 9am to 6pm on weekdays, open in the evening. You can keep store pages blocked during the day while leaving Twitch open after hours, all in separate blocksets.

The cost is complexity: LeechBlock's options page is dense, and the first setup takes a while. If you want granular gaming schedules it's worth it; if you just want the games gone, Focuh is faster to set up.

Free ways to block gaming sites on Chrome

Method	What it blocks	Schedule?	Free?	Account
Focuh extension	Gaming sites in Chrome, for a challenge	Session-based	Yes	None
LeechBlock NG	Gaming sites in Chrome, by hours/days	Yes	Yes	None
Focuh Mac app	Gaming sites and game apps, system-wide	Session-based	Yes	None

The first two block Chrome tabs. The third — covered below — is the only one that reaches the actual games.

What a Chrome extension can't block

Here's the honest limit: a Chrome extension controls tabs in Chrome and nothing else. For gaming, that gap is bigger than for most distractions, because games so often live outside the browser:

The installed Steam, Epic, or Battle.net launcher opens whether or not you've blocked its website.
Roblox, Minecraft, and most native PC games run as desktop apps an extension never sees.
Switching to Safari or Firefox sidesteps a Chrome-only block entirely.

So if your distraction is browser games, a Chrome extension genuinely solves it — those games can't run with the domain blocked. But if you're losing hours to Steam or a native game, blocking the website does almost nothing, because the app doesn't need the site. See our system-level vs browser blocking guide for why this happens.

Blocking game apps: OS-level blocking on Mac

To block the game applications — not just their websites — you need a tool that works below the browser. The free Focuh Mac app blocks both distracting sites and native apps during a focus session, using macOS Accessibility APIs. Start a session and Steam, Roblox, and your browser games are all out of reach across every browser, until the session ends.

Because it doesn't live in chrome://extensions, the Mac app is much harder to switch off mid-session than any extension. If you want both layers — fast browser blocking plus app blocking — run the free Focuh extension in Chrome and the free Focuh Mac app together. Neither costs anything.

How to block gaming sites during work hours

A common goal is keeping games blocked while you work and open afterward. Two clean ways to do it:

By the clock — Use LeechBlock NG with a gaming blockset set to your work hours on weekdays. Predictable and automatic.
By the session — Use the Focuh extension or Mac app and start a focus session when you sit down. Blocking turns on when you begin and off when you stop, so it tracks your actual work rather than a fixed schedule. This suits study sprints and deep-work blocks that don't follow exact hours.

If you tend to "just check" a game store on a break and lose an hour, session-based blocking tends to hold up better, since there's no daily window where everything reopens at once.

Which method should you choose?

"I lose time to browser games like CrazyGames or Poki" — A Chrome extension fully solves it. Use the Focuh extension for simplicity or LeechBlock NG for schedules.

"I lose time to Steam, Roblox, or native games" — A Chrome extension won't help. Use the Focuh Mac app to block the apps themselves.

"I want gaming blocked at work, open at home" — Use LeechBlock NG by hours, or a Focuh focus session tied to your work blocks.

"I'll just switch browsers or open the launcher" — Go OS-level with the Focuh Mac app, which a browser block can't match.

Match the tool to where the games actually live. Browser games die with a Chrome block; native games need the operating system. Most people who game in a tab can fix it in under a minute — and the ones who game in an app now know why the extension alone never worked.

Install the free Focuh extension to block gaming sites in Chrome, or get the free Focuh Mac app to block game apps too.
