Brain Teasers For Kids and Adults

Brain teasers exist to challenge, intrigue, and amuse. They stump many people because, most of the time, the puzzles don’t follow typical protocol. Brain teasers encourage critical thinking.

Frequently, these mind teasers encourage a false assumption. When the answer is revealed, it’s not uncommon to hear a groan or two.
