T-Rex Run has been a popular game for many generations since the early days of the Internet. Chorme created this game to allow users to "play temporarily" when they lose their network connection.

T-Rex Run is simulated with extremely simple graphics depicting a dinosaur running in the desert. The player must guide the dinosaur to jump and bend to avoid obstacles. The farther this dinosaur runs, the higher the game score. Despite its simple gameplay and graphics, this T-Rex is popular among many users.
