The challenge:
There are five sisters in a room:

• Ann is reading a book.
• Margaret is cooking.
• Kate is playing chess.
• Marie is doing laundry.

So, what is the fifth sister doing?

Take a moment to think… Got an answer? Many people assume she must be doing something completely different. But here’s the catch:

Chess isn’t a solo game.

The answer:

The fifth sister is playing chess with Kate.

Since Kate is playing chess, she obviously needs an opponent. And with only five sisters in the room, the remaining sister is the one sitting across from her.

Did you catch the trick, or did it sneak past you the first time? That’s the fun of these clever little riddles—they test your attention to detail as much as your logic!
