Unblocked Games for Chromebook - Play 430+ Free Games

Why most "unblocked games" sites are bad on Chromebooks

Three Chromebook-specific reasons the legacy unblocked-games sites struggle:

• Flash games don't run. Chromebooks never had Adobe Flash properly installed — the plugin was sandboxed and unreliable even before Flash was killed in December 2020. Today, 100% of Flash-era games on the legacy sites just don't load on ChromeOS. UBGHyper runs every Flash classic via Ruffle (an open-source Flash emulator written in WebAssembly) — no plugin, no install, works natively on ChromeOS.
• WebGL stutters on older Chromebooks. Many school Chromebooks are 4GB RAM, low-end Intel Celeron models that can't sustain 60fps WebGL games. UBGHyper has hundreds of lighter HTML5 and Ruffle titles that run smoothly even on entry-level Chromebooks — see "lighter games" picks below.
• Popup ads break the back button. Some legacy sites have popup networks that hijack the back button or open new tabs that can't be closed properly. On a school Chromebook with limited resources, that crashes the whole browser. UBGHyper has zero popup ads on the player.

Lighter games for older Chromebooks (4GB RAM, Intel Celeron)

If your Chromebook is the standard-issue 4GB Intel model, these games are the smoothest:

• Flash via Ruffle (very light) → Riddle School 1-5, Hobo 1-7, Sift Heads 1-5, Cookie Clicker
• Pure HTML5 (no WebGL) → 2048, Tetris, Block Blast, Bitlife
• Single-canvas physics → Drive Mad, Drift Boss, Stickman Hook
• Idle / clicker → Cookie Clicker, Idle Breakout, Idle Mining Empire

Heavier games (need a newer Chromebook with 8GB+ RAM)

These look amazing but need more horsepower. If your Chromebook is a Lenovo Duet, HP x360, or Acer Spin from the last 2-3 years, you'll be fine:

• Cuphead — gorgeous, demanding
• Hollow Knight — Metroidvania, large textures
• Polytrack — 3D racing with track editor
• Minecraft 1.12 — full Minecraft 1.12 in browser
• Plants vs Zombies 2 — heavy assets

Chromebook-specific keyboard shortcuts on UBGHyper

• / — jump cursor to search box on the homepage. Faster than clicking.
• ` (backtick, top-left of keyboard above Tab) — toggle tab disguise. Tab title, favicon, and URL bar all swap to Google Classroom (default), or pick from Docs, Khan Academy, Desmos, Slides in the dropdown.
• F — fullscreen in most games. Useful on small Chromebook screens where the browser chrome eats too much space.
• Esc — exit fullscreen.

What to do if UBGHyper is blocked at your school

If you can see this page but a specific game doesn't load — that's usually a CORS issue with a single game's host, not a UBGHyper-level block. Try a different game in the same genre.

If the whole UBGHyper domain is blocked, your school has specifically added ubghyper.github.io to their blocklist. Two paths forward:

1. Try a github.io mirror. The repo is open-source — you (or any other student) can fork it on GitHub and host the mirror at {your-username}.github.io in about 5 minutes. The mirror is a brand-new URL the school filter hasn't indexed.
2. Use UBGHyper at home, save progress, sync across devices. The /saves.html export tool lets you back up your saves to a JSON file, so even if school blocks one URL you can pick up where you left off elsewhere.

Save export for IT-reset Chromebooks

School IT departments occasionally reset all Chromebook profiles — usually at the end of a term or when migrating to a new domain. That wipes localStorage and every game progress you've accumulated. UBGHyper's save export tool exports all your game saves as a JSON file you can email to yourself or save to Google Drive, then re-import on a fresh profile. The tool is unique to UBGHyper — none of the legacy unblocked-games sites have it.
