Google Chrome has a hidden browser game called Dinosaur Game. When a user tries to view a website without an internet connection, it pops up. Chrome displays a tiny, pixelated T-Rex instead of the usual "No Internet" page, inviting the user to overcome obstacles and survive as long as possible.

Dinosaur Game is easy to play:
There are no complicated levels or controls—just a simple, never-ending sprint.
The game has a retro style reminiscent of early 8-bit video games thanks to its black and white pixel graphics.
Chrome Dino makes waiting for the internet to reconnect a little more fun because it's designed for offline entertainment.
The day-night cycle and special random graphics are examples of hidden features. The game's versatility is further enhanced by the ability to play it on mobile devices using Chrome.
Dino Game has become a cultural icon since its launch. The game is frequently referenced in programming tutorials, memes, and as a fun distraction during internet outages.
