Irregular Primes: Anti-Knight
(Published on 22. December 2024, 16:36 by perchik)
Normal sudoku rules apply. Cells separated by a knight’s move cannot contain the same digit.
Circled cells contain prime numbers. If the circle covers multiple cells, these are read as a single number, e.g. 1 and 3 would be thirteen.
(This is a sequel to a previous “Irregular Primes” puzzle, where the additional restraint was non-consecutive - see here if interested.
Solution code: Row 8

That was awesome...
thank you;
it took me a while -starting at it- to remember that 1 is NOT a prime! the rest was easy ;-)
