5.0 out of 5 stars mind boggling, October 6, 2012
Verified Purchase(What's this?)
This review is from: Sudoku on the Half Shell: 150 Addictive Sujiken® Puzzles (Paperback)
I bought this for myself and was quite impressed with the puzzles. I liked it so much that I ordered one for a relative that also likes Sudoku. It figuratively and literally adds another dimension to the challenges. I highly recommend it for someone that is addicted to Sudoku.

This product is great fun for sudoku fans. It gives another perspective on solving these puzzles and is more challenging than one might think.

5.0 out of 5 stars A must have for sudoku players, April 24, 2011

This review is from: Sudoku on the Half Shell: 150 Addictive Sujiken® Puzzles (Paperback)
Who would have thought that the "Latin Squares" that the Swiss mathematician Leonhard Euler apparently developed would lead to one of the most popular games of the 21th century. A quick search of Amazon reveals numerous puzzle books but none with the originality of Dr. Heineman's Sudoku on the Half Shell. Using the basic concept of Sudoku (9x9 and 3x3) Dr. Heineman adds his unique challenge of using the diagonal as an added element. This brilliant twist makes for an enjoyable and inventive game. I highly recommend this book and am personally looking forward to the follow-up addition.
