Lock Quest: The Robot Factory

The factory door is open!

The door slides up with a hum. A hundred robots turn, wave all at once, and get back to work. One of them rolls over with a tray of oil-free cookies for your team.

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

Your mission

The robots have locked the factory door five ways, and they are not being mean about it. Robots just do EXACTLY what they are told, one step at a time, in order. To get in, your team has to think the way a robot does. Follow every instruction exactly. Never skip a step. And when a robot gives you clues, use all of them.

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.
