The Dino Game: A Timeless Classic Hidden
 

Also known as the Chrome Dinosaur Game, this offline mini-game appears when you try to load a webpage without an internet connection in Google Chrome. A small dinosaur—officially a Tyrannosaurus Rex—appears above the error message. By pressing the spacebar or tapping the screen, the dino game comes to life and begins to run across a desert landscape filled with obstacles.

What unfolds is a fast-paced, endlessly scrolling platform game. You control the T-Rex by jumping over cacti and avoiding flying enemies. It’s straightforward, but don’t be fooled: the longer you run, the faster the game becomes, testing even the most skilled players.
