Offline Dino is an arcade game developed by PuzApps, available for free on Android devices. The game features the Lonely T-Rex, who is stuck in a desert and has to run endlessly while avoiding obstacles such as cacti and pterodactyls. As the game progresses, the speed increases, making it more challenging to survive. The game's goal is to survive for as long as possible through days and nights, with the colors inverting after reaching specific milestones.

The game's colorful graphics make it stand out from the original T-Rex game, and it is likely to have additional features added in the future. The game is a play on going back to the "prehistoric ages," which was before the existence of the ubiquitous internet. While the moment without internet connection may alienate some younger people, it reminds us of a time when people could only go online in certain places.

Offline Dino is a simple yet addictive game that can last almost an eternity, maxing out at approximately 17 million years, the same amount of time that the T-rex was alive on Earth.
