Welcome to the UBG 76 Retro Portal. As one of the most trusted names in the unblocked community, we know that school filters are always trying to shut down the fun. To ensure you can always access the classic "76" library, we maintain this dedicated list of Legacy Mirrors and high-speed proxies.
These sites are our "Gold Standard" servers. They are optimized for classic HTML5 titles and multiplayer arena games.
Primary 76 Hub: Classroom Unblocked Games
Educational Node: EZ Classwork
Classroom Node 15x: Classroom 15x
Pizza Edition Hub: The Pizza Edition
If the main .net domain is restricted, please rotate through these alternative "UBG" and "Classroom" stations. We update these daily to stay ahead of firewall updates.
| Node Name | Connection Link | Type |
| Node 98 | ubg98.io | ⚡ Fast |
| Node 911 | ubg911.net | ? Emergency |
| Node 10x | classroom10x.io | ? Lite |
| Node 20x | classroom20x.net | ? Stable |
| Node 6x | classroom6x.website | ? Stealth |
1. Use Different Extensions
If the .net version is blocked, it's usually because the "76" keyword was flagged. Try our .io, .top, or .website mirrors listed above—they often sneak past simple filters.
2. Hard Refresh Shortcut
Is a game stuck on a black screen? Press Ctrl + Shift + R. This clears the cached "Blocked" version of the site and forces your browser to pull a fresh, unblocked version of the game from our 76 mirror.
3. Stealth Tab Cloaking
Every UBG 76 Mirror includes a Panic Button. Look for the "Shield" or "Settings" icon to instantly mask your browser tab as Google Drive or Wikipedia.
The "76" network is built for stability. We focus on "Retro-Performance," ensuring that classic games like Slope, Run 3, and Happy Wheels run smoothly on any school Chromebook. By using our official mirrors, you get encrypted connections, fast load times, and a massive library of unblocked favorites.
