Your mission

Page the library mouse needs to get into the book drop, but it is locked five ways. In a library, everything has its place, and that place depends on ABC order. When two words start with the same letters, you have to keep going, letter by letter, until they are different. Page left clues, but no directions.

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.
