Your mission

Sam and Pam are twins who share one toy chest. Sam loves SYNONYMS, which are words that mean the same thing. Pam loves ANTONYMS, which are words that mean the opposite. They used some big words on these locks. If nobody on your team knows a word, think about where you have heard it, and use the other words to rule things out.

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.
