Super-Tough Jigsaw Sudoku, Volume 1

Note: I swapped out the Jigsaw puzzles in Volume 1 for a more accurately graded set on September 16th. - Jim

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. If you like these puzzles, also check out my other puzzles.
