Your mission

Bamboo the panda has a clubhouse full of cupcakes. Club + house. Cup + cake. Those are compound words, which means two small words joined into one new word. The door is locked five ways. Bamboo left picture clues but no directions, so your team will have to work out what each one means.

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.
