The offline dino game is a classic, browser-based game that activates automatically when users are offline and try to access a webpage in Chrome without an internet connection. Players control a pixelated dinosaur that runs across a desert landscape, avoiding obstacles like cacti and birds by jumping over them. The objective is to survive for as long as possible, with the game progressively increasing in speed to challenge players' reflexes. It's a simple yet addictive way to pass the time during internet downtime.
