More about this game
Switchlight Lab is a logic puzzle where your goal is to turn every light on the grid blue. The board consists of a grid of lights that are either amber or blue. Tapping a switch on the edge of the board flips the colors of every light in that entire row or column. You must figure out the correct sequence of flips to bring all the lights into alignment. The game tracks your moves, challenging you to match the optimal par score for each of the six chambers.
Tips
- Check the optimal par score before you start to know how many moves you should aim for.
- Flipping the same row or column twice just undoes your move, so look for a different path.
- If you make a mistake, use the Undo button to step back without restarting the whole chamber.
