Juosan Killer sudoku
(Published on 25. October 2021, 05:54 by udukos)
Normal sudoku rules apply.
An area surrounded by a dashed line will be called a cage. Digits may not repeat within a cage. A number in the top left corner of a cage indicates the sum of all the digits in that cage. Odd digits(1, 3, 5, 7, 9) can appear consecutively for more than two cells vertically, but not more than two cells horizontally. Even digits(2, 4, 6, 8) can appear consecutively for more than two cells horizontally, but not more than two cells vertically.
Here is a 6*6 example (with colouring for better visualization) for illustration with a link for solving.
Here is a link to the main puzzle.
Have fun!
Solution code: Column 1 Row 8

I believe this wonderful puzzle was the first Sudoku posted on LMD at least that uses this ruleset, and it makes excellent usage of it! It deserves to be preserved and remembered!
I have remade the puzzle in SudokuPad for any future solvers: https://sudokupad.app/9a8sa810r6
