Jumper

Jumper is a free online vertical bouncing game you can play instantly in the browser. Your character bounces automatically from platform to platform — steer left and right to keep climbing higher and chase a new best height. No download, no sign-up, and playable on phone or desktop.

How to play

• Your character bounces up on its own each time it lands on a platform.
• Steer left and right with ◀ ▶, the arrow keys, or by tapping either side.
• Aim for the next platform above so you keep bouncing and climbing.
• Some platforms slide side to side — time your landing to catch them.
• The screen scrolls down as you climb, and your height becomes your score.
• If you miss and fall off the bottom of the screen, the run is over.

Make small, early steering corrections instead of yanking hard at the last moment — the character drifts, so line up the next platform while you are still rising. The sides of the screen wrap around, so slipping off the left edge brings you back on the right, which is handy for reaching an awkward platform. Watch moving platforms and aim for where they will be when you come down, not where they are.
