Here to make amends for my cake comment. My birthday is 20 February and I wanted to say the puzzle was a birthday treat. It came out wrong. Apologies.

Kind regards, sujoyku

Nice puzzle,for me fell like a 2 stars for sure.

**
Thank you for your kind comment, wentel21! I think if one is familiar with the XV-constraint, it is easier than 2 stars. But obviously as the setter I am biased since a solution always feels easier once you know it.
Kind regards, sujoyku
