Eye-catchingly elegant, satisfyingly tricky logic puzzles! Sudoku is one of the most popular, ubiquitous puzzles around--but most of the sudoku out there are computer-generated, with no thought given to the solving experience, leading to repetitive, forgettable puzzles.

The puzzles start out gently, introducing new twists and increasing in difficulty as the book goes on, with illustrated hints making the book accessible to all skill levels.
