Revised December 2015 - with all new puzzles Collection of 120 computer generated Sudoku puzzles of the world's most popular number game. All puzzles in this book are generated using our own invented algorithm that can generate puzzles of any dimension, even 81x81. The number of possible boards is only theoretically estimated so far. Our algorithm can generate all these boards practically. As all puzzles are randomly computer-generated, volume V contains puzzles different than volumes. The revised edition contains an altogether different set of puzzles.
