How it works
BLINK BATTLE is a free, browser-based blink-reaction game. You stare down an animated opponent and must blink back only when both of its eyes truly close together. Time your closure to sync with the opponent's and you deal damage with a combo multiplier; follow a wink or half-close feint, or blink outside the true window, and you lose HP. Blink detection runs entirely on your device using MediaPipe Face Landmarker inside a Web Worker — camera frames are processed in local memory only, with no uploads, no recording, and no identity recognition. The session uses just three signals per frame: eye-closure scores, confidence, and timestamps.
