(Published on 23. December 2025, 03:45 by Sudonym)

Cryptic sudoku using 2 different sandwich sums of 1-9 and 2-8. Very fun puzzle I think. Hope you enjoy this one. Link to puzzle sudoku pad There is a video solution plus more puzzles on youtube channel "sudoku spot" Normal sudoku rules apply. Numbers outside the grid on the bottom and right are the sum of the numbers between 1 and 9 in that row/column. (Sandwich sums) Numbers outside the grid on the left and top are the sum of the numbers between 2 and 8 in that row/column.

Solution code: Row 2

Reply...no worries. Appreciate the mention in your puzzle. Would love to know what you think of my "chess mates" one, haven't had many solves.

Whew! That's a workout! Thanks for including the answer check - it's really easy to get mixed up which sandwiches were which, and I appreciated only having to back up a few steps when I made mistakes!

Reply.... you're welcome. Yes the only thing i dont like about this website is there are no solutions to the puzzles. Love it otherwise, some great puzzles, but I hate it when I get stuck and can't check where I have gone wrong. I have been doing a solution on youtube before I post my puzzles for this reason.
