If you need a fresh Sudoku challenge, this is the book for you!
There are many difficulty levels of Sudoku logic puzzles but this highly challenging book only contains difficult ones - and we mean difficult. None of the puzzles in this book are easy, so if you think you're a Sudoku expert, try one of these 'perfect' puzzles (there is only one solution and you'll never have to guess an answer) and see how good you really are.
This book contains 125 difficult Sudoku number puzzles and all solutions.
