Run 3 is a platformer in a tunnel floating through space. You run forward automatically; the tunnel's floor has holes, and when a jump won't do, you run onto a wall — and the wall becomes the floor. Gravity follows you. That one idea, combined with hundreds of short levels, is why Run 3 has stayed one of the most-played browser games for over a decade.
Joseph Cloutier (Player 03) released it in 2014 as the third game in the Run series, and it grew far beyond the first two: a branching map of levels, an Explore mode with a story, and a cast of characters — the Runner, the Skater, the Lizard, the Child, the Bunny — each with different speed, jump and abilities. This page runs the full browser version.
Over 300 across the main tunnel and its branches, plus Infinite mode. Explore mode saves your position on the map so you can come back to it.

Yes. It is a light 3D game with arrow-key and space controls and nothing to install. It has been one of the most-played school games for years for exactly that reason.
