Kropki Cross

(Published on 29. September 2024, 16:40 by LunarOnSudoku)

This is my first attempt at constructing a sudoku puzzle! I had the idea of this kropki constraint a while back so I decided to see if I could make anything out of it and I think it came together pretty well! Would love to get some feedback so please comment! :D

Rules:

- Normal sudoku rules apply: Place the digits 1-9 in every row, column and 3x3 box.

- Diagonals: Digits must not repeat on the main diagonals.

- Killer Cages: Digits cannot repeat in cages and sum to the number in the top left most cell of the cage.

- XV Pairs: Cells separated by a V sum to 5. Cells separated by an X sum to 10. Not all V's or X's are necessarily given.

- Centre Kropki: 2 cells diagonally separated by a black dot are in a 1:2 ratio (e.g. r2c3 is in a 1:2 ratio with r3c2 and r2c2 is in a 1:2 ratio with r3c3).

Happy solving! Link to the puzzle here on SudokuPad!

Solution code: Row 1 (read from left to right, 9 digits in total)

19:45 for me. Very very nice flow - many will do it quicker but I never felt stumped at any point.
