Phenomenal puzzle! The logic is beautiful, though it helped me to keep a list of two-digit primes handy. What a feeling of accomplishment once I figured out the tricks to set up the solve, and I couldn't believe how well it flowed once I found the way in.

What a great puzzle! Thanks for sharing WhatsWrong.

@Ragna, use the following bookmarklet to convert F-puzzle to CTC-

javascript:void(p=exportPuzzle(),p?window.open('https://app.crackingthecryptic.com/sudoku/?puzzleid=fpuzzles'+encodeURIComponent(p)):alert('Unable%20to%20extract%20a%20puzzle%20definition'))

What a wonderful puzzle! Thank you for sharing. :-))
Solving would be better and smoother not on this horrible f-puzzle. My old eyes cannot recognize those tiny digits. I don't know to convert a puzzle into CTC or sudokupad.
