The Testament of Sherlock Holmes Hints

How can I solve the number-lock puzzle?

  • 1 of 10: Start by getting the 7 over to the left edge of the puzzle, since it's the leftmost digit of the goal order.
  • 2 of 10: Fortunately, that step is pretty easy to achieve. Start by moving the 7 and 5 up and all the way to the left.
  • 3 of 10: You can then move the 2 and 6 down, to the right, and up into the slots vacated by the 7 and 5.
  • 4 of 10: After that, move the 7 and 5 down to get the 7 into its correct position.
  • 5 of 10: The digit that's supposed to be next to the 7 is the 8, and getting it into position is going to be a little bit harder.
  • 6 of 10: One way to do it is to start by moving the two 4's up.
  • 7 of 10: Then move the 6 and 8 down and left until they can move up into the slots vacated by the two 4's.
  • 8 of 10: Move the 5 and 3 down and all the way to the right, then move the 8 and 2 down and left until they can move up next to the 7. That'll get you the next two numbers in sequence order (since the goal order starts with 782).
  • 9 of 10: That'll give you a good idea of how the puzzle works, and you should be able to take it from there.
