A tip before you start
A move toggles the chosen tile and its horizontal and vertical neighbours, but never the diagonals. Tapping the same tile twice reverses that move.

About Glow Circuit
Glow Circuit is a compact logic puzzle played on a three-by-three light panel. Every starting pattern is made by applying legal moves to a cleared board, so a solution always exists. Experiment with the connected switches and clear all nine lights; choose New puzzle for a fresh pattern.
