Kropki puzzles by KrazyDad

Here are hundreds of free Kropki puzzles suitable for printing.

On this page you'll find four puzzle variants that all use Kropki clues, which appear as white and black dots. These extra clues are used to determine relationships between the two adjacent squares that have a dot between them. A white dot means the two numbers are consecutive, such as 3,4 or 4,3. A black dot means the two numbers have a 2:1 ratio (the larger of those two numbers will always be even). Any adjacent pair of numbers not clued with a dot has neither of those properties, being neither consecutive, nor with a 2:1 ratio. Note that the number pair (1,2) may be clued with either a black or white dot.

Kropki puzzles have the interesting property that the number of givens for the puzzle can be significantly smaller than a regular sudoku (and sometimes there are no givens at all). I've created a few additional variants here, both named after famous people from Belarus (Olga Korbut and Marc Chagall).

Kropki was created by Vladimir Portugalov, of Belarus, in 2005, for the World Puzzle Championship. The name Kropki comes from Belarusian кропкі, meaning dots. The puzzle has also been published under the name "Dots Sudoku".

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 a 1-per-page format. You can use the formatting option on the download page to produce foldable booklets that conserve paper and ink.
