How to play

Read the dots and tap two fireflies that blinked the same way. A group locks on the next beat. Tap again before that and it opens. Locking the right group late leaves too few beats.

Detailed rules

  1. 1.Today's arrangement comes from the Korea Standard Time date. The same day is the same arrangement.
  2. 2.The fireflies blink on different periods. The period numbers are not written on the buttons.
  3. 3.Two taps make one group. Before it locks, another tap opens it.
  4. 4.Only matching blinks make a sound. A mixed group barely sounds.
  5. 5.Locking the right group late cannot win on the beats left. Inputs are not sent to a server.

Origin & history

Firefly Choir is a daily puzzle about grouping fireflies that blink on different periods. Matching blinks make a sound. The target line is never shown.

FAQ

Why is there no written line?

The line you should reach is not shown ahead. You only have the blinks that already happened.

Why does waiting lose?

A group sounds from the next beat. Spending the beat that just revealed a blink, in order to be sure, leaves too few sounds.
