Your mission

A peacock keeps its best feathers in a locked box. The fanciest part of a peacock is its tail, and the tail end of a word can be fancy, too. A suffix is a small word part added to the END of a word. It can turn "care" into "careful" or into "careless", which mean opposite things. Look closely at the ends of words, and watch for words that only LOOK like they have a suffix.

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.
