Treasure Trails/Guide/Light boxes
Light boxes are a puzzle players will occasionally need to solve for a master Treasure Trail. Light boxes contain a 5x5 grid of lights and 8 switches to turn them on and off. The goal of the puzzle is to light all the lights.
If destroyed, or otherwise lost, the puzzle will have to be solved again from the beginning.
Solving the puzzle[edit | edit source]
One strategy is to concentrate on one light at a time and flip every switch, taking note on a piece of paper of which switches control that light. Repeat this for all lights until finding one which is only controlled by one switch. The position of that switch which turns that light on is the permanent position of that switch. So you no longer need to check that switch and have halved the remaining switch permutations. In other words, finding one is twice as hard as finding the next with the first one being the hardest to find.
There is also a brute-force method, which requires turning the switches on in this order from left to right:
