Nancy Drew: Treasure in the Royal Tower Hints

How do these sliding locks work?

  • 1 of 4: There is no absolute answer because the lock combination changes each time you try.
  • 2 of 4: Basically it's a "concentration" puzzle.  Click on any of the bars until one stays over to the left side.  Try another and, if you guessed wrong, the first one will move back.  If you guessed right, the first and second will remain on the left.
  • 3 of 4: The door will unlock when all six stay on the left side.
  • 4 of 4: It helps to jot down the ones that work on a sheet of paper.
