Time memory
A few seconds can feel surprisingly different when you have to recreate them. Time asks you to listen to a measured interval, remember its length and reproduce it with a deliberate press and release.
Play nowHow it works
- Listen to the signals that mark the target interval.
- Hold the control for the duration you remember, then release it.
- Submit your answer and compare the reproduced interval with the target.
Sound is part of the timing cue. Easy introduces a single interval; Hard asks you to combine two intervals. On a keyboard, the game also supports holding and releasing the Space key when the timing control is focused.
