One to Fifteen
(Published on 21. December 2020, 01:00 by Lisztes)
Normal Sudoku rules apply. Each row, column, and 3x3 box contains each number from 1 to 9 exactly once.
Killer Sudoku rules apply. The sum of all numbers in a cage (marked with dashed lines) must match the small number printed in its corner. No number appears more than once in a cage.
Disjoint Sudoku rules apply. Cells that appear in the same position relative to their default regions must not contain the same number.
The puzzle is also available online.
Solution code: Column 5 and Column 9

Really enjoyable! I used the disjoint sets constraint quite a lot. I like the idea of having 1 to 15 killer cages, which I filled in nearly in order. Thanks a lot!
