About UBGHyper

A hand-curated, ad-free catalogue of 430+ browser games. Built for school, Chromebooks, and slow networks.

What it is

UBGHyper is a small games site — every title hand-picked, tested, and embedded directly into the page. The library covers modern HTML5 games, Flash classics running on Ruffle, idle games for long sessions, and a handful of multiplayer browser titles.

It exists because most unblocked games sites are cluttered with intrusive ads, broken links, and designs that haven't been touched since 2009. UBGHyper aims to be the opposite — fast, clean, and focused on the games.

Works at school

Every game runs in your browser — nothing to install, no plugins, no Flash Player. There's a one-key tab disguise that swaps the title and favicon to Google Classroom, Docs, Khan Academy, or Desmos. Press ` to toggle it.

How games run

Each game is embedded via an iframe pointing to its own hosted directory. This keeps the main site lightweight and lets individual games be updated independently. HTML5 games run natively. Flash titles use Ruffle — a Rust-based Flash emulator compiled to WebAssembly. Everything runs client-side. Closing the tab ends the session completely.

Features

  • Search & filter — by name, tag, or category. Filter state lives in the URL so you can share it.
  • Favourites — heart any game to save it. Stored locally, no account.
  • Playtime tracking — per-game daily charts plus a GitHub-style activity heatmap on the Stats page.
  • Save export — back up your Bitlife / Cookie Clicker / Retro Bowl progress as JSON, restore on another device.
  • Tab disguise — swap title and favicon with one keypress.
  • Fullscreen + focus mode — every game has a native fullscreen button and an immersive focus mode.
  • Smart random — picks from categories you actually play.

Your data

All user data — favourites, playtime, recent games, theme, in-game saves — lives in your browser's localStorage. It never touches a server. Export it from the Saves page if you want it to survive a browser-data clear.

The site uses Google Analytics for aggregate traffic only. No PII is collected, no cookies are sold, no emails are gathered.
