We found some brain activities online for you to challenge your brain.
PEOPLE HAVE BEEN challenging their wits since at least the third millennium BCE, when ancient Sumerians carved riddles into stone tablets. (Try this one, for example: “There is a house. One enters it blind and comes out seeing. What is it?”) Over time, we’ve developed puzzles that test a variety of skills—and revamped the most popular forms to make them ever trickier. Yet as the difficulty of brainteasers has grown, so too has our urge to tap them for sweet respite from the everyday. Enjoy a little escape and see how many of these you can crack. (Pssst. It’s a school.)
