Friendly XV

(Published on 29. December 2020, 01:39 by Woodsy)

Normal Sudoku rules apply.

Green shaded cells are Friendly cells. The digit in a friendly cell must match it's row, column, or box. Rows are numbered from top to bottom. Columns are numbered from left to right. Boxes are numbered starting in the top left, going left to right, then top to bottom. Cells that are not green, cannot contain a friendly digit.

Cells separated by an X must sum to ten. Cells separated by V must sum to five. Not all X and V clues are given.

The number outside the grid is a little killer clue and indicates the sum of the digits on the diagonal.

This is my first published puzzle so I welcome all suggestions for improvement.

Solution code:

Column 2 followed by row 8.

@woodsy just FYI: In Penpa, you need to turn BORDER: ON and then you can simply type in X and V on edges using Number Mode.
@swaroop2012 - thanks!

RockyRoer - Thanks for the great advice. I loved Masquerade. I was trying to make a link for mine on Penpa, but couldn't figure out the XVs. I forgot about f-puzzles. I think I will join the discord for Cracking the Cryptic.
