Examine each key carefully and use your stylus to move the keys and find the one that fits on the lock.

UK Version

Which of these keys opens the door?

Use the stylus to move the keys and find the one that fits the lock.

US Version

At a glance, the ends of the keys look too intricate when compared with the simple shape of the keyhole.

Concentrate on finding a key with a shape that matches the structure of the lock.

UK Version

At first glance, the ends of the keys look much more intricate than the shape of the keyhole.

Look closely and try to find a shape that matches the keyhole.

US Version

Who's to say one end of a key is any better than the other?

UK Version

Have you tried all six possibilities?

What's that? There are only three keys? That's certainly true, but try a little lateral thinking.

US Version

Turn each key around and try inserting the part you'd normally call the grip.

UK Version

Rotate the keys and grab them by the part you'd normally insert in the lock.

Solution

Correct

That's right!

US Version

Did it take you a while to figure it out that the portion of the key resembling the grip was actually the part that fit the keyhole? Answers can be often in the most unlikely of the places.

UK Version

How long did it take you to realise that the grips of the keys could also be inserted into the lock?

This little lesson about the danger of making assumptions should serve you well in your puzzle-solving adventures.
