Through the Looking Glass
(Published on 1. September 2020, 10:51 by cam)
As far as I know, this is a novel variant with some very interesting logic.
-Ordinary sudoku rules apply.
-Little killer rules apply. The arrows indicate the sum of the digits in the direction of the arrow. Some sums may contain the same digit more than once.
-Looking glass rules (new!) apply. Each digit (1-9) has a "buddy" that appears in all of the cells where the row and column indices are swapped. For example, if 1's are buddies with 4's and there is a 1 in r5c2, then there must be a 4 in r2c5. Ones being buddies with fours implies that fours are buddies with ones. It's possible for a number to be it's own buddy. Figuring out the buddies is part of the puzzle.
This is really a very simple rule, but if you are confused by my explanation or have clarifying questions, please let me know.
Here is the puzzle. Enjoy! :)
Solution code: Row 5 followed by column 2

Love this "Looking Glass" concept, but I'm having such a hard time with this puzzle. Anyone have some advice on solving little killer puzzles
@Geelow98 Thanks for your comment :) I would recommend writing out the possibilities on a piece of paper. If there are a lot, you're probably looking at the wrong clue, missing something about the other constraints, or the puzzle is bad (but the last one is just my opinion >:]). Maybe there are a few possibilities that all imply something that allows you to move forward.

Thanks for making a little killer with some structure (I usually struggle with the more traditional ones). :-)
If you like this one, you might enjoy my Mystery Killer Triplets (little killer sudoku) (id=0003ZS).
@SudokuExplorer Thanks! This puzzle of yours looks interesting. I've added it to my list. Hopefully you can get enough people to play it and get a rating. It's getting harder and harder these days :)

@Voyager I got rid of some tags :) Sorry about that. It was late and I totally wasn't thinking
