Subway Surfers is the endless runner that has been on every phone since 2012: Jake sprays graffiti on a train, the inspector and his dog give chase, and you run down the tracks dodging trains and barriers, collecting coins, jetpacks, magnets and hoverboards. Kiloo and SYBO built it, and it has been downloaded more times than almost any game ever made.

Yes. It is a light 3D game that runs in the browser with nothing to install, and it plays well with arrow keys.
