How to Play Run 3
Run 3 is a space-themed running game where you navigate through tunnels floating in outer space. The twist: you can run on walls and ceilings.
Run Forward
Your character runs automatically. Use arrow keys to move left and right and jump over gaps.
Walk on Walls
Run into the side of the tunnel to switch to the wall. Gravity changes and the wall becomes your floor.
Avoid Gaps
The tunnels have missing tiles. Fall through a gap and you drift off into space. Game over.
Unlock Characters
Progress through levels to unlock new characters with different abilities like jumping higher or skating faster.
When a gap looks too wide to jump, try running onto the wall instead. The perspective change often reveals a path.

Run 3 Features
Gravity Mechanics
Run 3 lets you walk on any surface in the tunnel. Jump to a wall and gravity shifts. This core mechanic makes Run 3 unique among running games.
Multiple Characters

Huge Level Count
Run 3 has over 300 levels across its Explore mode plus an Infinite mode for endless gameplay. New tunnels offer fresh challenges.
Run 3: A Deep Dive
Run 3 is the third installment in the Run series created by Joseph Cloutier and hosted on Coolmath Games, where it has consistently ranked among the most popular titles for over a decade. Set in a network of tunnels floating in outer space, the game builds upon its predecessors by adding new characters, a branching map system, and the signature gravity-defying wall-running mechanic that lets players transition seamlessly between floors, walls, and ceilings.
The game stands out through its ingenious level design and the wall-running system that redefines spatial awareness in a platformer. When you run off one surface, gravity pulls you to the nearest adjacent wall, turning every tunnel into a multi-faceted obstacle course. Each unlockable character has distinct abilities such as higher jumps, skating momentum, or the power to knock away crumbling tiles, adding strategic variety to how players approach each level.
Run 3 appeals to platformer fans, puzzle solvers who enjoy finding optimal routes through the branching galaxy map, and completionists aiming to unlock every character and hidden tunnel. The explore mode offers a lengthy campaign, while infinite mode provides endless replayability. Its simple controls paired with genuinely challenging level design make it equally rewarding for young players discovering platformers and veterans chasing flawless runs.
