This (variant) killer sudoku is the successor of my last puzzle "Unique Duo" and again requires the solver to find two unknown cage totals. I think this puzzle is more difficult and if you like to have a small hint, feel free to send me a hidden comment. As always your feedback is highly appreciated. I wish you a joyful solve!

- Normal Sudoku rules apply.

- Killer cages: Digits in a killer cage do not repeat and sum to the clue in the top left. Each cage in the grid has either the total X or Y which have to be determined by the solver.

- XV: Digits joined by an X sum to 10. (Not all X are given.)

- Dots: Digits joined by black dot have a 1:2 ratio. (Not all dots are given.)
