Knightly Exclusive Dominoes
(Published on 8. August 2024, 00:00 by Tingo)
I'm back from my long break. Hope you all enjoy my first set since the beginning of the year!
The rules are as follows:
Normal sudoku rules apply.
Cells that are a knight's move (in chess) apart cannot contain the same digit.
Digits in cages must sum to the total in the top left corner of the cage. Digits may not repeat in cages.
Cells joined by "V" sum to 5. Cells joined by "X" sum to 10. Not all Xs and Vs are given.
Black dots separate cells of 2:1 ratio values. Not all black dots are given.
Digits along gray lines are palindromes and must be read the same forwards and backwards.
Additionally - all cell pairs (dominoes) joined by a clue are unique within that clue type. For example, if a black dot joins a domino, and the values of those two cells are 3 and 6, the 3/6 domino cannot be used for other black dot joined dominoes. This does not exclude any other clue type from using that same cell value pair, providing that clue type also only uses the cell value pair once.

Questions, comments, concerns and jokes are all welcome! Thanks for playing!
Solution code: Row 9 followed by Column 4, 18 digits total

Very approachable. Exclusivity constraint not needed. Thx for setting!

After reading the comments fiets, I decided to try solving without the last constraint and even then it was definitely a 1-star difficulty. With the constraint it would have been even less. But enjoyable nevertheless!

I think you have asked for only 18 digit solution code. A 1* puzzle should ask for 81 digits.

Welcome back, Tingo! Looking forward to the return of some Irish dottage :)

3:20 speed run. The exclusive rule is not needed at all.

Thanks for this fun little puzzle, Tingo! Nice break-in and flow from start to finish. (I think you can use the exclusive set for the break-in, but you don't need it.)

Very fast but fun.
I did not use the exclusive rule either.
Nice flow.

I used the exclusive constraint but probably was other options as well. Maybe depends on the techniques used.
Fast and fun puzzle.

I didn’t use the additional constraint either

I might be wrong, but I don't think that I used the exclusivity constraint at any point in the solve.
