Killer Sudoku is a very popular variant of classic Sudoku that adds some new challenges. These puzzles have more going on and can be extremely satisfying to solve. Once you try them, you'll find it very hard to go back to boring plain old Sudoku This book has 108 puzzles, in order of difficulty ranging from Tough to Insane, using the same grading system as my puzzle website, Krazydad.com. Each puzzle has a single, unique solution. This is a LARGE PRINT book, with one large puzzle per page. I also publish a 4-per-page Killer Sudoku series with 360 puzzles per book.
