The game can be launched in the Chrome browser on both desktop and mobile. The control is the simplest: when you see that black dinosaur in your browser signifying that there is no Internet connection, just hit the spacebar to launch the game. The spacebar is also used to leap over obstacles. The down arrow is used to duck. If you are on mobile, just tap the little Chrome Dino to get into action and avoid obstacles, too.
The objective is to survive as long as possible. The background color will shift from light to dark (the alteration of day and night) after reaching certain milestones. The T-Rex game will stop once you fail to avoid the next obstacle or once the Internet signal recovers.
