The dino game is a hidden offline game that activates when your device loses connection to the internet while using the Google Chrome browser. A message appears on the screen that says "No internet," along with a small pixelated Tyrannosaurus rex. By simply pressing the spacebar (or tapping the screen on mobile), the T-Rex starts running across a desert landscape, dodging cacti and pterodactyls.

The game was first introduced by Google in September 2014 as a playful way to entertain users while they waited for their internet connection to return. However, due to its popularity, it was later given a dedicated URL (chrome://dino/) so users could access it anytime, even when they were online.
