Light box detail

The Light box is a puzzle given to the player when doing Master level Treasure Trails. The goal of the puzzle is to turn all of the lights on.

Methods & StrategiesEdit

The box contains 8 switches. Only one switch permutation of the 256 will light all of the lights. The 25 lights sit in a 5x5 grid.

One strategy is to concentrate on one light at a time and flip every switch, taking note on scratch 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:
