Firefly Fields
A logic puzzle of light
Release fireflies into a sleeping garden until every tile glows. Each one lights its whole row and column, two fireflies may never see each other, and the numbers on the stones keep count.
Three simple rules
How to play
Light every tile
Tap a grass tile to release a firefly. Its glow runs along the row and the column until a stone or the edge stops it.
Out of sight
Two fireflies must never see each other. If they share a row or column, a stone has to stand between them.
Read the stones
A number on a stone is exactly how many fireflies sit next to it: above, below, left or right. Diagonals don't count.
