XY-Cages II, "Chainlink"
(Published on 10. October 2025, 07:00 by glum_hippo)
A sequel to my first XY-Cages puzzle. Please also check out Richard's tribute to this rule set as part of the SVS series.
Standard Sudoku rules are in effect. That is, no repeats in row, column, nor 3x3 box. Killer cages may not contain repeat digits.
A white diamond between two cages means that the difference between their cage totals is equal to the topmost/leftmost digit in the column/row in which that diamond appears.
A black diamond between two cages means that the ratio between their cage totals is equal to the topmost/leftmost digit in the column/row in which that diamond appears.

Cool puzzle! Certainly not an easy start and it took me a while to tie everything together for that breakthrough, after that the solve went rather smoothly for me x)

Fantastic puzzle! The chainlink is very powerful to get started, but after that it isn't all too trivial, so challenging until the very end.
Thanks!

I’m glad you enjoyed it! The original version had a given digit and I’m glad I removed it haha..
