Inner Clock

Test your internal sense of time after a stopwatch disappears. The classic challenge asks for a stop at ten seconds, while daily puzzles and a level path introduce rhythm, prediction and changing clock speeds. Results show how early or late each input was. The challenge road goes beyond counting seconds, introducing missing beats, remembered rhythms, obscured motion, and changing clock speeds. The daily set is shared between players and produces a shareable result.

Start a timing challenge and use the main button to reproduce the required interval or rhythm. In the classic mode, stop at ten seconds after the visible timer disappears.

Click, tap, hold, or Space: main button. F and J: left and right inputs in two-hand rhythm levels.

Practice a puzzle type before the daily challenge, which allows only one attempt. Use the early/late result and ghost replay to adjust your next timing estimate.
