Lock Quest: The Giant's Toolbox

The toolbox is open!

The lid creaks open. Inside is a hammer the size of a door, and a tiny tape measure, just your size. The mouse squeaks, "That one is for you."

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

Your mission

A giant left his toolbox in the workshop, and it is locked five ways. Giants measure everything, and they mix up their units all the time. Sometimes inches, sometimes feet, sometimes yards. You cannot compare two measurements until they are in the SAME unit. 12 inches make 1 foot, and 3 feet make 1 yard. A little mouse who lives in the workshop noticed every clue. Look closely and work together.

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.
