Challenging Killer Sudoku Puzzles

Each booklet contains a collection of eight different puzzles, 1-per-page, with a page of answers in the back. The booklets are ordered by ascending difficulty -- the puzzles in book 100 are much harder than the puzzles in book 1.

These puzzles are in PDF format and need the Adobe Acrobat Reader to view or print. If you like these puzzles, also check out my other puzzles.
