Glad I watch CtC! Coloring made this quite easy, although it still took me about an hour

Nice puzzle. Don't forget about the negative constraint on XV pairs (like I did initially), or progress will grind to a halt prematurely.

Loved it. I could have used digits early but prefered to color all the way and then enter all the digits at once, so satisfying. Thanks!

This was a wonderful puzzle but not to hard as someone with experience in XV sudoku and coloring, so I'd give it 2 stars
