It’s a test of your brain to solve these puzzles. Glad to see there’s a second level book so I can continue along with more and increasing challenge.

I have a certain expectations level. And gosh, this puzzle exceeded it a lot! My math-loving neurodivergent brain was tickling while solving the hidden message. It wasn't hard, but cool and logical and just-felt-right!

If you care enough to read the reviews on a puzzle book then this book is for you. Very eclectic collection of puzzles that will make you have to reach into every part of your mind to figure them all out.

My son loves this game and it has challenges him to want to learn fractions and decimals at 8 years old. This is truly an amazing game and we can make it more or less challenging by deciding how many numbers have to be used to obtain the answer.

I would definitely recommend this game to a teacher. [Proof! is] an awesome, fun game for students to engage in while learning math!

The final result is absolutely stunning with hundreds of hidden details and funny things. Definitely worth every second, minute, and hour I spent on it.

It’s awesome to look at and fun to complete. We have it framed in our house now. :)

Working the two Master Theorem books has been a joy - by far my favorite "puzzle books" of all time. Thank you (and the TMT team) for these incredible time-wasters!
