Glow Grid

How to play

• Tap a light to toggle it and the four lights next to it (up, down, left, right). The goal is to turn every light off.
• Every board is guaranteed solvable — New Game scrambles from an all-off board by applying random taps.
• Choose 3×3, 5×5, or 7×7 for an easier or tougher grid. Your best move count per grid size is saved on this device.
