This is the seventh book in the World Of Sudoku series of handcrafted Sudoku books. The book contains 200 handcrafted Classic Sudokus in four difficulty levels - easy, medium, hard and evil. The first three levels of sudokus do not require the use of any advanced techniques, whereas the sudokus under the evil category requires the solver to make use of advanced sudoku techniques. All the sudokus in the book can be solved without guessing.
This book is different from most of the sudoku books as the sudokus in the book are not generated from any software. Most of these books use computer generated sudokus with randomly given digits. As a result, the sudokus look very similar. Most of the time, the same software is used to generate sudokus for different books and we have the case of having same sudokus in different books. Moreover, many sudokus from these books do not have any logical solve paths and they also have multiple solutions for many sudokus.
All the sudokus in this book are test solved multiple times for uniqueness of solution. The sudokus in the book are high on aesthetics and have pleasant solve paths.
The solving time of the author is mentioned for each of the sudokus so that the solver can compare his/her solving times with those of the author's. Each page contains two sudokus and there is ample space around each sudoku for pencil marking digits around the grid.
The book is sure to give the solvers many "aha" moments. Have fun.
