Dinosaur from Google Chrome

Dino or Lonely T-Rex is an uncomplicated but addictive arcade game that occurs in Chrome when there is no internet connection. This game gives you the opportunity to kill time, as well as evaluate your reaction speed and concentration.
The appearance of the Dinosaur in Google Chrome has a curious backstory.
It was originally created as an Easter egg and entertainment for users who are faced with a lack of Internet connection in the Chrome browser. When the web browser cannot load a web page, it displays an error message and an image of a dinosaur. Google developers decided that instead of simply displaying an error page, you can add a small game to brighten up the wait for connection recovery. For the first time such entertainment appeared in Chrome in 2014. Dino quickly became very popular, and many users play it even with an internet connection, just to pass the time.
