How it works

Short runs, honest scoring — built for searchers who want to play before reading.

1
Headphones on
Pure tones are easier to judge with headphones. Allow audio when the browser asks.
2
Hear each tone
We play three targets in a row. Replay if you need to — then you match from memory.
3
Drag the slider
Preview plays your guess. Submit when you’re ready; each round is scored 0–100.
4
Reveal
After each round you can hear target vs guess side-by-side. Total max is 300.
