A cell lights up somewhere on screen — no warning, no countdown.

Tap it as fast as you possibly can.

No colors to read, no deadline pressing on you — just how quickly you react.

25 targets, back to back — that's the whole run.

Every reaction is scored on raw speed, then converted to its own beats-per-minute equivalent — the faster you react, the higher the number.

Your average BPM across all 25 targets is what lands you on the board.

Every run gets tracked on The Standings — your best score, ranked against every other player.
