Poly Jumper is a fast-paced free online arcade platformer built around one core skill: nailing your jumps at exactly the right moment. You run through colorful low-poly worlds where platforms shift, gaps widen, and obstacles appear with little warning. Miss your timing by a fraction of a second and you start over, making every successful run feel genuinely satisfying.

The game ramps up speed as you progress, so the muscle memory you build early gets tested hard in later levels. Moving platforms require you to read their rhythm before you leap, not after. The polygon art style keeps the visuals clean and distraction-free, which actually helps since you need to focus entirely on platform edges and landing spots. There are no drawn-out cutscenes or tutorials - you learn by doing, which is exactly how arcade games should work.

Poly Jumper is a great pick for fans of precision platformers, reaction-based arcade games, and anyone who enjoys short-session skill challenges they can replay obsessively. If you like free jumping games online, platform runner games in browser, or Unity3D arcade games with no download required, this one belongs in your rotation. It suits both casual players chasing a single clean run and competitive types grinding for a perfect level clear.
