Your mission

The band room locker is locked five ways, and the concert starts soon. Every sound begins with something shaking back and forth very fast. That shaking is called a vibration. A fast vibration makes a high sound and a slow one makes a low sound. A big vibration is loud and a small one is quiet. Short, tight and thin things shake fast. Long, loose and thick things shake slowly. Bamboo the panda left clues all over the band room. Listen with your brain.

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.
