Advent Calendar – Dec 9

I have a very yummy puzzle for you today–Christmas Cookies!

This is a sudoku variant called ‘Kropki pairs’. In a kropki puzzle, there are black and white dots between some of the cells. A white dot between 2 cells indicates that the digits have a difference of 1 (are consecutive). Black dots indicate digits have a ratio of 2 (one is double the other).

If you are subscribed to the standard or family advent calendars, you’ll find links to the pdfs of today’s puzzle below.

And for some tips on solving kropki puzzles, check out today’s video:

  1. Third times the charm! I kept making wrong assumptions on the dots (aka chocolate chips), but finally got it worked out after restarting twice! Great puzzle.

    • Glad you got it in the end. I find that making wrong assumptions and other such mistakes just help me understand the rules more clearly for future puzzles. Often times when I try a new puzzle type, I just play around with it and see what breaks the puzzle, and then I have better idea of how to approach them.

  2. Made a mistake early on the left which somehow didn’t block me until I only had about 20 numbers left to fill. Spent 5 minutes trying to unwind and figure the mistake before restarting, and almost immediately making the same mistake (spotted the second time). I obviously need more practice with Kropki! Still immensely enjoying this set of puzzles.
