Your mission

The snow is falling hard, and the cabin door is locked five ways. Biscuit the bear and his friends have been playing outside all day: picking teams, cutting paper snowflakes, skating on the pond, and building snow forts. Think it all through carefully, and there is cocoa waiting inside.

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.
