Giant Book of Critical Thinking

Do you have what it takes to master the Mensa critical thinking challenge? Be sure you don't just accept the facts. You must uncover connections and identify the often hidden cause-and-effect relationships. It's just you, a pencil or pen, and some of the most stimulating mind-benders you've probably ever seen.

Can you imagine the mirror image of a given object or the best way to connect a series of geometrical shapes? Are you able to figure out the shortest distance between any two points or the number of salami slices that fit on a pizza? Then you're a pro at visual thinking puzzles.
