## Riddle: Find the key

I have keys, but no locks and space, and no rooms. You can enter, but you can't go outside. What am I?

This one tricks you by having you think about space that can be entered. Then it gets you to merge that with a space without rooms where you can't leave. You might even be hung up on those keys. That's where you should linger. Think about that word. What are some other meanings of "keys"—especially that don't require locks?

## Riddle: Beachy keen

What gets wet while drying?

This one has a simple answer even though it stumps most people who try to figure it out. Wet and dry seem like they always have to be opposite, so you might get tripped up. Think of an object that can, ahem (hint!) absorb or be both.

Answer: A towel. Can you guess these animals based on their footprints?

## Riddle: Family affair

Riddles try to send your train of thought off in scattered directions. Try to stay clear and just follow the logic. Using letters as placeholders for names like "Uncle Bob" or "Aunt Linda" makes straightforward relationships seem difficult.

Answer: A is D's aunt. Here are more brain teasers that will leave you stumped.

## Riddle: Line up

What are the next three letters in this combination? OTTFFSS

This super hard question asks you to determine the relationship between the letters. They seem random: a vowel, two consonants from the tail of the alphabet, two from the front, then two more. What could they mean? What's the pattern? In this case, think of common strings of words to get you closer. But it still seems almost impossible to hit on the solution.

Answer: E N T (Each letter represents the first letter in the written numbers: One, Two, Three, Four, Five, etc.).

## Riddle: Color test

First, think of the color of the clouds. Next, think of the color of snow. Now, think of the color of a bright full moon. Now answer quickly what do cows drink?

Some riddles work by getting your brain to go through a series of associations so you get locked in and can't think of alternatives. Be careful with this riddle. Is the question really connected to that color you were asked to think about? Most folks say that cows drink milk because they're fixated on the color white.
