Geometry Flap is a free online arcade game where you control a fast-moving arrow through a relentless black-and-white maze of geometric obstacles. Tap the screen to flap your arrow up and down, timing each move to slip through narrow gates and dodge precision traps that appear without warning. One bad tap and it's over instantly – back to the start.

The game keeps things brutally simple: one control, zero margin for error. The sharp geometric art style makes every obstacle easy to read but nearly impossible to react to fast enough, which is exactly what makes it so addictive. Between runs you can unlock dozens of arrow skins, giving you a small but satisfying reason to keep pushing your high score. The difficulty ramps up steadily, so runs that last ten seconds early on start feeling like genuine achievements as your reflexes sharpen.

Geometry Flap is a perfect fit for fans of hypercasual reflex games, one-tap arcade challenges, and anyone who enjoyed games like Flappy Bird or geometry-style runners. If you search for free tap arcade games, hard one-button games online, or geometry reflex challenges no download, this game delivers exactly that kind of punishing but fair gameplay loop. Play it in your browser on mobile or desktop – no install, no sign-up, just pure reaction testing from the first tap.
