How to Block Bloxd.io - Header

If you've noticed your child spending hours on a game called Bloxd.io, you're not alone. It's one of the most popular Minecraft-style web games today, but it’s also one of the hardest for parents and school IT admins to block.

Why? Because the developers of Bloxd.io use a strategy called "Mirroring." They create dozens of different web addresses (URLs) that all lead to the same game. If a parent blocks the main site, the child just switches to a different link like doodlecube.io or bloxdhop.io.

The Challenge: Why Traditional Blockers Fail

Most parental control tools require you to manually enter every single website you want to block. With Bloxd.io, this is a "whack-a-mole" game that parents can't win. New mirrors pop up every week, often disguised as educational sites or "math" tools.

Did you know? There are currently over 40 known mirror domains used by Bloxd.io to bypass school and home filters.

We built KidsGuard to solve exactly this problem. In our latest version (v1.3), we've introduced a dedicated "Bloxd.io Shield" that does the heavy lifting for you.
