The Secret Door: Whispering Compass
Locals say a group of pirates hide their treasure behind secret doors and only left modified compasses as the clue to open it. A regular compass will always point to the north and the south but not these compasses. The pirates have modified it into some kind of puzzle. Martha, an innkeeper who wants to be a treasure hunter has figured out the way to unlock the door by forming correct angles on the compasses. But to unlock all doors, she needs your help!
