There is a HUGE DIFFERENCE between these two puzzles - - -
The chest puzzle resets to its original state after every attempt.
This means you must either make notes, draw diagrams, or take screenshots each time you make it go.
Waay easier is the one in medium detective, which retains your changes; meaning you only need to keep tweaking it until it works.
So - thanks for bowing and scraping, but I don't deserve a lot of credit for solving the friendly one.
Whether I go back to the chest puzzle remains to be seen.
