About Glow-Grid
Glow-Grid is a free daily puzzle game inspired by Lights Out. Light up all 25 cells of the grid. Every day brings a new puzzle, and every puzzle has a solution.
How to play
Tap a cell to flip it and some of its neighbors. What happens depends on the cell you tap:
- Light up all 25 cells to win.
- Cells on the edge have fewer neighbors. Those are ignored.
- Try to find the shortest path. Fewer moves is better.

This is a small demo with the same rules. Tap the cells and listen. Each cell has its own note.
Daily puzzle
The puzzle is created from the date, so everyone gets the same grid on the same day. Each puzzle starts from a solved grid and is scrambled with random moves. This is why it can always be solved.
You can go back to play older puzzles, and keep a daily streak.
Features
Tap a card to hear its note.
