Your mission

This is Lock Quest number one hundred. Every friend you have met along the way is here: Felix the fox, Quill the owl, Penny the pig, a little mouse, and Zip the frog. They have locked the Golden Vault five ways, with the five kinds of puzzle they like best. No new rules. Just everything your team has learned about thinking carefully, checking each other, and never, ever guessing.

How to crack a lock

  • Pick any lock from the menu at the top. You can solve them in any order.
  • Read every clue before you start. One clue alone is never enough.
  • Use scratch paper. Draw pictures, make lists, and cross things out.
  • Tap the buttons to build your answer. Then press "Try the lock".
  • A lock will not tell you which part is wrong, so be sure before you try.
