About this game

Brainsplit is a two-thumb reflex game drawn in ballpoint on a page of lined paper. Each thumb steers its own half of the screen: hop between lanes, dodge what comes, and keep both sides alive at once. It is a multitask game at heart: a quick brain and focus test that trains your reaction speed and hand coordination, one more run at a time.

Every day there is one deterministic daily challenge: the exact same track for every player, worldwide. No luck, no seed you can reroll, just who splits their focus best. The global leaderboard resets with it.

WHAT YOU GET

- A one-more-run arcade loop, drawn by hand on ruled paper
- A daily challenge on a shared track, with a worldwide ranking
- Pens, marks and trails to unlock, and a shop to spend your coins in
- Difficulty tiers that open up as your reactions get faster

PLAYS OFFLINE

The whole game runs offline and without an account. Signing in is only there to put your name on the leaderboard, and you can delete your account and its scores from inside the app at any time.

Free to play, supported by ads. No pay-to-win: everything you can buy is cosmetic.
Two-thumb reflex game: dodge lanes, split your focus, beat the daily track.
