How to block "unblocked games" at school

Students trade new unblocked-games links every week. Blocking last month's list isn't enough. Here's what works.

Short answer

Unblocked games sites are copies of game sites hosted on new addresses, often on Google Sites, GitHub Pages or fresh domains, so a fixed block list misses them. Sheepdog Filter blocks 33,000+ known game sites, matches unblocked-games and proxy names, and checks new sites seen on school networks every hour, blocking the ones that turn out to be game or proxy mirrors.

What "unblocked games" are

They're copies of popular browser games, like Slope, Retro Bowl and 1v1.LOL, posted on addresses a school filter hasn't seen yet. Students share links in class chats, and a new mirror appears as soon as an old one is blocked. Many are hosted on free services like Google Sites or GitHub Pages, so they look harmless to a simple filter.

Why most filters fall behind

Most filters block a fixed list of famous game sites and update it every few weeks. A mirror made yesterday isn't on any list yet.

How Sheepdog Filter keeps up

  • 33,000+ game sites on our block lists, refreshed every hour, from Roblox to the newest .io games.
  • Name matching. Sites with telltale names, like "unblocked", "proxy" or the names of popular games, are caught even when they're brand new or misspelled.
  • Hourly learning. Every hour we check sites newly seen across our network and add the ones that turn out to be game or proxy mirrors, so one school's discovery protects everyone.
  • Brand-new domain blocking. Very young domains, where most fresh mirrors live, can be blocked as a group.
  • Proxies and VPNs too. The same tricks students use to reach games, web proxies and VPN apps, are blocked, and you get an alert when someone tries.

Questions school IT asks

A teacher uses an educational game site. Will it break?

If it's caught by the games category, allow it in one tap from your dashboard and it works for everyone.

Can we allow games at lunch only?

Yes. Set a schedule that allows games during lunch, and they're blocked again afterwards automatically.
