Rules:
Normal sudoku rules apply. Pairs of adjacent numbers on a line must sum to a prime number. Not all possible lines are given.

**************************************************************
We have RELEASED our second Sudoku Puzzle Hunt last weekend. Patrons of the channel can download it at our patreon page (link below). Today's puzzle may help with the puzzle called Marvolo's Ring!

If you are NOT a patron of the channel on Patreon and would like to get a taster of the hunt then you can download the preamble (which consists of two letters: one from Angus MacGuffin and one from ______; together with the notes about the puzzles which seem to have been written by a very unpleasant character indeed) and try the first puzzle at the link below.
