Your mission

Felix the fox is driving across the United States, and his trunk is locked five ways. His map shows every state as a square tile with its two letters. On some maps the colors show five regions: the West, the Southwest, the Midwest, the Southeast, and the Northeast. Felix left clues, but he did not leave directions. Figure out what he was thinking.

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.
