About Marble Runner
Marble Runner is a 3D physics marble platformer in the browser. You roll a heavy ball across floating sky islands, collect gold coins, and reach a glowing goal gate before you fall into the clouds. The whole game is about the feel of the marble: momentum, friction, short jumps, and braking into turns. Clip a platform edge and you drop; line up a gap with speed and you clear it. Falling costs a fall on the scoreboard and sends you back to the last checkpoint.
Control it with WASD or the arrow keys to roll relative to the camera, Space to jump, Q and E to orbit the camera, Esc to pause, and R to respawn. On a phone, use the on-screen stick and Jump button. Fifteen courses escalate from a simple bridge run to moving platforms, spinning bars, bumper pillars, hazard strips, boost pads, jump pads, and multi-tier climbs. Buy new ball skins with coins you bank on clean runs. Start on Sky Path and learn how far the marble coasts after you let go of the keys.
