I'm on Gaurden Moon. I managed to get the darn lights off but can not get them all on at same time. I have started this game more times than I can count. My game does not start out like one on Utube I have different lights on and off. Darn it I guess I will never get the lights on to get the chest.
Once you get the hang of it, it's quite easy.
start with any gold "button" light, whatever you call them.
Just 1) click on that first unlit gold one-then click on each in that row and in the column but don't click your original.
Then, 2) pick another one that is gold (not lit yet) do the same thing, by clicking on each in the row and column except for that second original choice.
I was confused about which ones to click on.
Basically it is click on each in the row and column whether lit or not. Every one in the row AND column (but remember, again, NOT on the original unlit one you chose to start that sequence).
It is like so easy, once you figure it out.
HAVE FUN!!!
