# Fireflies

Multiples · 30 levels

Light up exactly the ringed beats of the night.

## How to play

- Each firefly blinks on a beat: every 3 lights beats 3, 6, 9, 12…
- Tap a firefly to put it in the jar; tap it again to let it go. Jar fireflies light up their beats.
- Make exactly the ringed beats glow: every ringed beat lit, every other beat dark.

Look at the smallest ringed beat: some firefly must light it. Later fireflies start late (“from 2” lights 2, 5, 8…), and two jars appear: a ringed beat in white needs both colours, a common multiple!
