Glow Grid

Every tap flips a cell and the cells above, below, left and right of it. Turn the whole grid gold. Twelve levels, from 3×3 up to 5×5.

How to play

Tap a cell to flip it and its four neighbours (gold ↔ dark).
Clear a level by making every cell gold.
Each level has a par move count. Finish at or under par for a bonus; speed adds a little more.
Tapping the same cell twice undoes it, so think before you tap.
Keyboard: arrow keys move, Enter or Space taps, P pauses, R restarts the level.
