No, my Eye-Q Visual Puzzles for Reason-able People does not make this list of three greatest pen-and-paper puzzle books of all time. I doubt that any of you will be able to guess any of the three even though these three books do what many puzzle publishers claim that their puzzle books do and what Lumosity claims that their video games do: they improve your brain.
These three books actually deliver on that promise without really promising it. That is puzzle humility.
So, here they are. The three greatest pen and paper puzzle books are . . . drrrrrrum rrrrrroll . . .
#3 the College Geometry Textbook
#2 the College Trigonometry Textbook
and the Greatest Pen and Paper Puzzle Book is
#1 the College Calculus Textbook
Surprised? You shouldn't be. Each of these books contains puzzles that are truly multi(ne)farious. The puzzles start easy and end breathtaking complex. In doing the puzzles in these books you are continuously learning and continuously challenging your mind. This is the real workout for your brain. And yes, just like in any serious workout, there is pain involved.
And the puzzles that you will find in these books are not merely math problems. They challenge your creativity, too. I know because I took a trigonometry class and two different calculus classes at University of Washington (I earned a 4.0 out of each of the three and felt exhilarated afterwards).
Many of the puzzles have multiple ways of solving them. Thus the challenge these puzzles present is not just of finding the correct solution (that is difficult enough), but also of finding the correct solution in a graceful way. That's right. There are aesthetically pleasing ways of solving these puzzles and there are aesthetically un-pleasing ways of finding the correct solutions. Few, if any, mainstream puzzle makers have created puzzles of such richness and depth as the ones that you will find in the Calculus Puzzle Book.
So, if you really want to give your brain a workout and you really want to be smarter and you like doing puzzles then get these three greatest pen and paper puzzle books and enjoy. (These books are expensive but you can save some money by getting them on Ebay or from Half-price Books. And whatver the price, they offer great value becaue there are literally thousands of puzzles in each book. You will be challenged for months and months trying to solve them all.)
