What Makes It Uncommon

Do you love logic problems? Are you crazy for crosswords? Do you get caught up in escape rooms? Then these mind-bending books will leave you pleasantly perplexed. Created by a mysterious figure known only as "M," each captivating collection is a glimpse into minds of The Master Theorem, a secret society of geniuses who indulged themselves in cyphers, puzzles, and code-breaking. Are you up to the challenge?

  • Choose the Original version, with 40 unique brain teasers (a.k.a. theorems) or the Elite edition that packs 40+ puzzles for intermediate to expert-level adventurers.
  • Designed to look like mystical tomes, both compilations are covered in intricate symbols, and each theorem is illustrated with full-color drawings and photos that will help lead you to the solution.
  • The theorems also include hints (written in a simple code so that you don't accidentally peek), with solutions in the back.
  • "M" estimates that a clever teen or adult might need weeks to complete the first anthology and months to conquer the second.
  • 213 pages each.
  • Made in Michigan.

Difficult But Fun!

I purchased two of these books, for a 13 year old and 17 year old. Both have described the book as difficult but fun. Great for deep-thinkers and puzzlers.

Great Puzzle Game and Brain Exercises

Got this for my grandfather who is a math and tech lover. He was recently diagnosed with early onset Alzheimer's and an old bleed that is affecting part of his brain. Got these exercises for him and my grandma, while also having fun and being age appropriate and not infantalizing. He was very excited when he got it for Christmas 🎄

I enjoy these puzzles

I bought this on a whim, and I really enjoyed this puzzle book. I pull this out in the evenings when I want an activity that's not on my phone or computer and usually work on them with my spouse. i also bring the book with me to gatherings with friends and pull it out to work on together. It's also great for traveling and gives me something to do at the airport. I am certainly not the strongest puzzler, so I'm glad it comes with hints.

Wonderful way to spend an afternoon

I wasn't exactly sure what I was getting into with this puzzle book, but I was pleasantly surprised. The puzzles are all different enough and require some serious thinking depending on the difficulty level. The back story is intriguing, and I am looking forward to the next volume.

Please answer Question 1- What is the DIFFERENCE between 'original' versus 'elite' editions? What's given is similarities… both have 40, elite has an unknown # > 40. Do any 'theorems' overlap or repeat between editions?
