White Kropki dots are simple, and there are only a couple of them. XV clues are more interesting, and there are a lot of those. Still not enough to make it clear how to solve the puzzle, but that’s because of the global constraint. This puzzle demonstrates an overt bias against knights: no knight’s moves allowed!
Rules:
Normal Sudoku rules apply.
Anti-Knight: Digits may not repeat in cells a chess knight’s move apart.
Kropki: Digits in cells separated by a white dot are consecutive.
XV: Digits in cells separated by an X sum to ten. Digits in cells separated by a V sum to five.
Not all Kropki dots, nor Xs, nor Vs, are given.
Estimated difficulty: 2 out of 5
