Lock Quest: The Capital Mail Truck

The mail truck is open!

Pip delivers the last package to the last capital and toots the horn. Every letter got where it was going, thanks to your team.

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

Your mission

Pip the mail chick drives the capital mail truck out West. Every state has one capital city, where its leaders meet to make laws. The capital is not always the biggest city! Las Vegas is the biggest city in Nevada, but the capital is Carson City. On Pip's map, a star means a capital and a dot means a big city. Today's mail is a mess, so your team will have to work it 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.
