What Is SZ Games?
SZ Games, also styled SZ Gaming, Super Zone SZ Gaming, or szgames.net, is a free, browser-based portal that hosts 250+ unblocked games you can play at school, work, or on shared networks — without downloads or installs.
The project is open-source on GitHub as sz-games/sz-games.github.io, maintained by a creator who goes by "Bobby", and is distributed via a Chrome/Firefox extension called Sz Games Portable.
"The Best Way To Play Game's In School"
— Official SZ Games Tagline
In 2026, SZ Games sits at the intersection of three trends:
- Unblocked gaming for students on restricted networks.
- Retro + modern web games delivered via HTML5/WebGL.
- Privacy-first extensions that inject games into any site.
This article explains how SZ Games works, what's on it, who runs it, whether it's safe, how it compares to Poki/CrazyGames, and what parents/teachers should know.
The Core Platform
szgames.net & sz-games.github.io
1.1 Origin and Hosting
The main site lives at szgames.net and is mirrored at sz-games.github.io. The GitHub repo description reads:
"The Best Way To Play Game's In School. This Site Was Made By Me (Bobby)"
It's a static site hosted on GitHub Pages, meaning it's free, fast, and hard to take down. Forks are allowed if you link back and give credit — but rebranding is prohibited.

Why Students Use SZ Games
The "Unblocked" Appeal
The School Network Problem
Most schools block gaming domains via firewalls. SZ Games counters this with a layered approach:
GitHub Pages Hosting
github.io is often whitelisted for education.
Tab Cloaking
Disguises the tab as Google Docs.
About:Blank Embedder
Opens games in a blank page that bypasses filters.
Proxies
Testing feature to route around blocks.
No Downloads
Nothing to install, so IT can't block executables.
"Whether you're in school, at work, or using a shared network, you can enjoy uninterrupted gaming with just a click."
Educational Claims
The site argues gaming during free time has benefits:
Boosts Cognitive Skills
Puzzles improve problem-solving and memory.
Enhances Coordination
Action games help hand-eye coordination.
Improves Social Interaction
Multiplayer encourages teamwork.
Relieves Stress
Fun break improves mood and focus.
SZ Games also lists educational games for learning and cognitive development: Riddle School, Learn To Fly.
