Your mission

The Great Snail Race is over, but the judge fell asleep and forgot who won. The prize box will only open for a team that can put everything back in the right order. No single clue is enough. Draw blanks on your paper, try a guess, and check it against every clue.

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.
