Twin prime sudoku
(Eingestellt am 29. Januar 2020, 15:44 Uhr von Shinya)
Beispiel:
In der Abbildung unten werden zwei Primzahl-Zwillinge in zwei Boxen gebildet. Links die 29 und die 31, rechts die 41 und die 43.
Das vollständige Rätsel muss alle zweistelligen Primzahl-Zwillinge enthalten, die nach den normalen Sudoku-Regeln in einer Box stehen können (also Zwillinge größer als 11/13 und kleiner als 100).
Viel Spaß!
Lösungscode: Zeile 8, Spalte 7

Yes, it may contain prime numbers from other twin sets, as long as the second number of the second set is missing.

May a box contain a third twin prime, as long as it doesn't contain its partner? For example, could a box contain the pair of twin primes 41 and 43, and additionally contain the twin prime 17 (but without its partner 19)?

@Shinya: Thanks for the clarification.
For anyone who hasn't solved the puzzle yet, this modification eliminates one of my two solutions, so now the answer is unique.

Hidden comments may only be seen by the puzzle author, the person who made the comment and people who already entered the right solution code. So it's totally fine to discuss the puzzle there.

It's a nice puzzle, but unless I'm making some stupid mistake, there are 2 solutions, which are similar enough so that they give the same solution code.
Is it OK to give the solutions in a hidden comment? (I'm new here, so I'm not sure if that's allowed.)
