Consecutive Sudoku puzzles by KrazyDad

Here are hundreds of free Consecutive Sudoku puzzles suitable for printing.

In these three variants, white bars are used to separate pairs of cells which are numerically consecutive, such as (3,2). If you don't see a white pair separating two cells, the numbers are guaranteed to NOT be consecutive.

Each collection is ordered by difficulty, with the easiest puzzles in Book 1, and the hardest in Book 100. If you are new to these puzzles, I recommend you start with Book 1. If you find they are too easy, skip ahead by 10 books or so. If you find the puzzles are getting too hard, move up to Book #1 of the next volume, and they'll get easier again.

My puzzles are provided in 1-per-page format. You can use the formatting option on the download page to produce foldable booklets that conserve paper and ink.

SPECIAL THANKS to programmer Phil Bordelon, who helped program and debug these variations.
