How to Block Games on Computer: Parental Controls That Actually Work

Blocking games on your computer is one of those tasks that feels impossible until you know the right tools. ⚡ I’ve spent years helping parents and productivity-focused users lock down systems—whether it’s to cut screen time or keep distractions at bay—and the solutions are simpler than you’d think.

The key isn’t just slapping on restrictions; it’s making them stick without turning the computer into a digital fortress.

Windows, macOS, and Linux each have built-in tools that work surprisingly well once you configure them right. On Windows, Parental Controls let you block specific games by app name or category, while macOS Screen Time uses app limits and downtime schedules.

For Linux users, tools like firejail or timeshift can lock down gaming apps at the system level. The trick is testing these tools on a secondary account first—trust me, you don’t want to lock yourself out of your own system.

Third-party software like Cold Turkey or OpenDNS adds another layer of control, especially if games keep finding loopholes. Cold Turkey blocks games at the application level, while OpenDNS filters game domains at the network level—meaning even if someone reinstalls a game, it won’t load.

Both methods are reversible with a password, so you’re not stuck forever. I’ve used these to block everything from Fortnite to Minecraft without breaking a sweat.

Here’s where it gets interesting: router-level blocking. If you’re dealing with a stubborn gamer or just want an extra layer of protection, setting up a DNS filter like Pi-hole at the router level blocks games before they even hit individual devices.

It’s the nuclear option, but it works—just don’t blame me if your kid starts complaining about "the internet being broken." We’ll cover all these methods step by step, plus how to handle the inevitable workarounds.

What you need

Step-by-Step instructions for setting up effective game blockers

Here's the foolproof method I use to lock down game access—no tech skills needed.

Windows has built-in tools that work surprisingly well. Open the Start menu and type "Family options"—this is your gateway to Microsoft's built-in parental controls. Click the first result to open the Family Safety panel. If you're using macOS, head to System Preferences > Screen Time instead.

For third-party options, I recommend Net Nanny or OpenDNS FamilyShield. These give you more granular control but require installation. The built-in options are easier to set up if you just need basic blocking.

In Windows, select your child's account from the Family Safety dashboard. Under Game restrictions, choose "Limit game time" or "Block specific games". For macOS, go to Content & Privacy Restrictions > Games and toggle "Limit Adult Games" to on.

Here's the thing—you'll want to test this immediately. Launch a game you want to block and verify it's actually restricted. If it still opens, you may need to add it to the blocked list manually by entering its exact name in the restrictions panel.

Use the time-based restrictions to create a schedule. In Windows, set "Game time limits" to 0 hours during homework time and 2 hours/day after school. For macOS, set Screen Time limits to match your family's routine.

I always recommend starting with 1-hour blocks during critical study periods. This gives your child time to adjust while still enforcing boundaries. The system will automatically lock games at the scheduled times—no manual intervention needed.

Prevent new games from being installed by setting App restrictions in Windows or Content & Privacy Restrictions on macOS. For Windows, go to Allow or block specific apps and block the game stores (Steam, Epic Games, etc.).

On macOS, enable "Prevent App Store and identified developer installs" under Content Restrictions. This stops new games from being downloaded entirely. Remember to test this by trying to install a game—if it fails, you're all set.

Have your child attempt to launch a blocked game. If it still opens, you'll need to add it to the restricted list. In Windows, go to Block specific games and enter the game's exact name. For Steam games, use the Steam ID found in the game's properties.

Check the restrictions panel weekly to ensure nothing was missed. Some games disguise themselves under different names—always verify by having your child try to launch recently installed titles. Adjust the schedule as needed based on your child's progress.

Tips & tricks for setting up effective game blockers

These simple strategies will help you create a foolproof system that actually works—and stays working. Trust me, I've tested every possible workaround kids try to bypass these controls.

Test Before You Trust: In Step 2, when you set up game restrictions, you absolutely must test immediately. I can't tell you how many parents set restrictions and never verify if they're actually working. Launch a game you want blocked right after setting up restrictions—if it still opens, you'll need to manually add it to the blocked list. Some games disguise themselves with different names, so always double-check by having your child try to launch recently installed titles.

Start with 1-Hour Blocks: In Step 3, I recommend beginning with 1-hour blocks during critical study periods rather than jumping straight to 0 hours. This gives your child time to adjust while still enforcing boundaries. The system will automatically lock games at the scheduled times, so no manual intervention is needed. This gradual approach prevents frustration while maintaining control.

Block Game Stores Too: In Step 4, don't forget to block game stores like Steam and Epic Games. I've seen too many parents block individual games only to discover new ones being downloaded. On Windows, use the "Allow or block specific apps" feature to block these stores completely. On macOS, enable "Prevent App Store and identified developer installs" to stop new games from being downloaded entirely.
