Your mission

Midnight the cat is having an uh-oh day. Nothing just happens for no reason, though. Something makes it happen. The thing that makes it happen is the CAUSE, and what happens is the EFFECT. In these pictures you can see one or the other. Your team has to work out the rest.

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.
