Play the iconic Chrome dinosaur runner — free, online, no download needed
The dinosaur game — famously hidden in Chrome's offline page — is one of the most-played browser games in the world. Now you can play it unblocked, right here, without Chrome, without downloading anything.
The dinosaur game (also called the T-Rex runner or Chrome Dino) is a browser game built into Google Chrome. It appears when you try to load a webpage with no internet connection. Players control a pixelated T-Rex dinosaur that runs endlessly, jumping over cacti and dodging pterodactyls to survive as long as possible.
The original game was created in 2014 by the Chromium team as an Easter egg. It became so popular that Chrome added it permanently to the offline error page. Since then, countless versions have been made — and our version at GameZipper lets you play it anytime, anywhere, on any device — no internet required, and no Chrome needed.
The Chrome dinosaur game is programmed in just ~600 lines of JavaScript. It features simple collision detection, procedural obstacle generation, and a surprisingly addictive difficulty curve that keeps players coming back.
Schools, offices, and public networks often block gaming sites. But the dinosaur game is different — it loads instantly, runs offline, and is lightweight enough to work on any network. That's why it's the go-to time-killer for millions.
GameZipper's version takes it a step further: it's always unblocked. No matter what network you're on, you can always access this classic runner game.
