Tough Sudoku Puzzles, Volume 3

Each of my books contains a collection of eight sudoku puzzles, 1-per-page, with a page of hints and a page of answers in the back.

These booklets are in PDF format and need the Adobe Acrobat Reader to view or print.

You can also download all 800 of these puzzles in a 4-per-page format ( with hints and answers, with answers but no hints, or with neither hints nor answers). If you like these puzzles, check out my other puzzles too!
