Glow Grid
PuzzleAbout Glow Grid
Glow Grid is a lights-out puzzle: every tap flips a cell together with its four neighbours, and the goal is to switch the whole board off before the moves run out. The grid grows from 3x3 up to 6x6, and a hint can mark cells of the solution.
How to play
Tap or click a cell to flip it and its neighbours. On a keyboard, move with the arrow keys, flip with Space or Enter and press H for a hint.
