Play in Sudokupad
Normal sudoku rules apply.
Killer cages: Within a cage, digits may not repeat and sum to the number given in the top left corner (10).
XV Pairs: Cells separated by an X also sum to 10.
Negative constraint: All X pairs are given.
Disjoint Groups: Cells in the same relative position in their 3x3 box may not contain the same digit.Solution code: Column 8 top to bottom.

Thanks krytolandrus, I'm glad you enjoyed the solve.
I am leaving the disjoint set rule, although some solvers haven't used it. When I was testing the puzzle with the disjoint rule I found a delightful deduction midway through and hope that aha moment is available for other solvers.
If someone doesn't use the rule, I'm certain there are multiple logical ways to find the solution.

Nice! Not too difficult at all, even without the disjoint set rule, which I didn't use at all. I would remove that from the rules.

I don't love that your username has 88 in it (especially on a German website).

Very nice and fun puzzle! I finished it in 17 minutes, so 2 stars seems reasonable. Thank you

Ooops, solved it without the disjoint group constraint. I probably made it harder for myself, but it also works.

Very clean construction, thank you!

Great puzzle! I always find something about negative constraint XV puzzles very meditative and soothing, and this one had a particularly nice flow.
