Intermediate Killer Sudoku, Volume 26
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. All these puzzles have a single unique solution.
These puzzles are in PDF format and need the Adobe Acrobat Reader to view or print.
You can also download all 800 of these puzzles, in the 4-per-page format ( with hints and answers, with answers but no hints, or with neither hints nor answers).
