Light Switch
About Light Switch
Light Switch is a clever logic puzzle. The board is a grid of lights, some on and some off. Tapping any light switches it, and it also switches the lights directly above, below, left and right of it. Your goal is to turn every light off within a limited number of moves. It sounds simple, but every tap affects five lights at once, so you need to think about how your moves combine. A good trick is to work row by row, using the row below to switch off the lights above it. The first levels use a four by four board, then the puzzle grows to five by five with more lights to clear. Every level is built from real moves, so there is always a solution. Moves you have left at the end give bonus points. Run out of moves and the game ends, but you can resume with five extra moves. Light Switch is free, works with taps and clicks, and saves your best score on your device.
How to play
- Tap a light to switch it and its four neighbours
Tips
- Clear the board row by row from the top
- Tapping the same light twice undoes it
- Corner lights only affect three lights
