The difficulty is probably 3 stars. I wish you joyful solving!
Hint:

| If XVs do not clearly determine the digits, consider whether the digits may instead determine the placement of XVs. |

Got stuck and had to do a bunch of bifurcation... I'm not sure how I could've avoided getting into that predicament (and I'm also not sure I fully understand what the clue means.)
