Prime and Ratio Pairs
(Published on 5. May 2023, 05:00 by Will Power)
Normal Sudoku rules apply. EVERY consecutive pair of numbers on all lines, moving away from the origin (where the three lines meet), is a prime number. Prime numbers overlap (ie: digit #2 for one prime becomes digit #1 for the next prime). Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. Thanks to Flycatcher, for the prime pairs line idea.
Solution code: Row 8 and column 1.

I would rate this 1* for difficulty. The kropis are quite forcing and the rest is easy.
