So Ad Age describes the credo of Nikoli, the Japanese puzzle company that invented the Sudoku craze and supplies 100% of the puzzles published in Japanese newspapers and magazines.
And when they say made, they mean literally handmade--unlike the computer-generated puzzles found in other American Sudoku products.
And that's one of the features that makes THE ORIGINAL SUDOKU BOOK 2-and THE ORIGINAL SUDOKU, published between seasons and already with 115,000 copies in print--unique.
The books celebrate the compulsive joy of Sudoku with symmetry, smartness, and elegance.
They invite you to match wits with the experts, to step into the 81-cell arena with a puzzle maker who has fiendishly anticipated your next step.
Fun without frustration.

More all-new puzzles--over 300, arranged from Easy to Very Hard.
The same chunky, easy-to-tote format, because once addicted you will be toting it around everywhere.
