Jump Jump World is a free browser-based arcade platformer that runs entirely in your web browser — no download and no install. You control a runner stuck to the rim of a small spinning planet, moving left and right around its curve while jumping to clear obstacles.
Each of the 20 levels introduces new hazards: spikes that kill on contact, walls that block your path unless you jump on top of them, asteroids that drift across the planet's surface, and geysers that erupt on a repeating cycle. The goal of every level is to survive the gauntlet and reach the finish-line rocket waiting on the other side, as fast as you can.
Jump Jump World works on both desktop and mobile. On desktop, use the A/D or arrow keys to move and Space to jump. On touch devices, on-screen buttons handle movement and jumping. Difficulty ramps up level by level, so later stages demand tighter timing and faster reflexes than the early ones.
Spikes end a run instantly and restart the level, so timing a jump over them matters. Walls simply block the way unless jumped on top of — clearing one from above lets the run continue across it. Geysers, which appear from level 11 onward, erupt on a repeating cycle and are deadly at any height while the spout is up, so they cannot be jumped: the vent sputters for a moment as a warning, and the way past is to cross while it is down. Reach the glowing gate and launch the rocket to finish the level and stop the clock.
Is Jump Jump World free to play?
Yes. It's completely free, with no download or install required — it runs directly in
the browser.
Does Jump Jump World work on mobile?
Yes. On touch devices, on-screen buttons handle movement and jumping, and the game is fully

How many levels does Jump Jump World have?
There are 10 levels, each played and timed on its own, ramping up from a gentle introduction
to a tight gauntlet of spikes, walls, and asteroids.
How do the leaderboards work?
Every level has its own top-ten board of the fastest times. Your best time on each level is
kept, and a free MKM Games account puts it on the board.
Do I need an account to play?
No. The whole game is playable without one, and your best times are saved in your browser.
An account is only needed to appear on the leaderboards and to carry your times between
devices.
