 SUDOKU FANATIC Jun 05, 2010

"R Joyner"
Big Book of 620 Sudoku Puzzles for the Frustrated Fanatic
Addictive! To check answers must go to a special address on the web. So, very, very challenging and fun.

Don't waste your money!
Puzzles have multiple possible solutions.
Worst of all, the book does not contain the answers and the website where you're supposed to be able to check your answers ([...]) doesn't exist as of the time of this review.
The other 2 websites listed as contacts for this book ([...] and [...]) don't exist either. Amazon should not be selling this book!

 Sudoku 620 Dec 09, 2010

This book was intended for my wife. She found it extremely hard, without the progressive easing of the user, as done by other SUDOKU books.

Good Book Dec 30, 2007
By Mathew Rietz
The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9, only one time each (that is, exclusively). The puzzle setter provides a partially completed grid.
Completed Sudoku puzzles are a type of Latin square, with an additional constraint on the contents of individual regions. Leonhard Euler is sometimes incorrectly cited as the source of the puzzle, based on his work with Latin squares.
The modern puzzle was invented by an American architect, Howard Garns, in 1979 and published by Dell Magazines under the name "Number Place It became popular in Japan in 1986, after it was published by Nikoli and given the name Sudoku, meaning single number. It became an international hit in 2005.
