Dinosaur Run is a dinosaur-themed endless runner in which players control a pixelated Tyrannosaurus rex to avoid obstacles and earn higher scores. Google developed this game, which is integrated inside the Google Chrome web browser. When there is no Internet connection, players can launch the game by clicking the spacebar or up on a computer keyboard or tapping the dinosaur image on a mobile device. During gameplay, the dinosaur moves continually from left to right across a black and white desert terrain, and the player must avoid obstacles like cacti and pterosaurs by jumping or crouching. The game accelerates steadily until the player collides with an obstruction or a pterosaur, at which point the game ends immediately.
