Revised - December 2015 - with all new puzzles. Response to our earlier publications of Sudoku puzzles up to a grid size of 25x25 prompted us to come out with this unique publication of 36x36 Sudoku puzzles. The book presents a set of 100 puzzles. Solving each puzzle calls for a real genius in you. Second edition now contains more puzzles, each at a lower price. All puzzles in this book are computer generated with our own invented algorithm that is capable of generating all possible combination grids of sizes up to 81x81, and even beyond. As these puzzles are difficult to solve, the book provides the solution to each puzzle.
