Glow Grid
Glow Grid is a lights-out style puzzle. Sleepy bulbs with faces fill the grid. Tapping one wakes it and its neighbours, and your job is to put them all back to sleep in as few taps as you can.
How to play
- Tap a bulb to toggle it and the bulbs next to it.
- Turn every bulb off.
- Match the par number of taps for three stars.
Tips
- Work from the top row downwards.
- Undo is free. Hints cap you at two stars.
- From level 15 bulbs have three states, so plan carefully.
