Lock Quest: The Dinosaur Dig

The fossil crate is open!

Inside the crate is a dinosaur tooth as long as your hand, and a note. "Found by the best dig team in the state."

You are now a Lock Master. Go tell your teacher!

Your mission

A crate of fossils is waiting at the dig site, locked five ways. Nobody was around to watch the dinosaurs, so paleontologists work like detectives. Rock layers pile up over time, so deeper layers are older. Footprints show which way an animal walked, which animal came through first, and even how big it was. Even raindrops can leave clues in mud. The rocks are the only witnesses. What are they telling you?

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.
