Lock Quest: The Big Red Barn

The barn door is open!

The doors swing wide and out trot three goats, two pigs, and one very proud rooster. Pip hops onto the rooster's back. "Thank you," she peeps. "It was getting loud in there."

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

Your mission

Pip the chick lives on a farm, and the big red barn is locked five ways. Something inside is making a lot of noise. Farm work takes careful thinking: which field gets which paint, how to push a stubborn sheep, and what Grandpa meant on his old flip phone. Think like a farmer. Slow, steady, and never skipping a step.

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.
