Whispering Knight
(Published on 22. October 2021, 01:13 by Phistomefel)
The usual sudoku rules apply. Additionally, cells that are a knight's move away from each other, may not contain the same digit. Adjacent digits along a green line must have a difference of at least 5.
The puzzle is also available online via F-Puzzles and CTC-App. Have fun solving!
Solution code: Columns 1 and 9

Several hours of desperation, but finally cracked it. Probably the hardest puzzle I’ve ever solved.

Mehrmals angefangen und wieder beiseite gelegt, bis ich endlich den Anfang gefunden habe.
Fantastisch konstruiert.
Started and put aside several times until I finally found the beginning.
Fantastically constructed.

My first 5 star Phistomefel Solve! It was challenging but I never felt frustrated. Super enjoyable!

Fantastic puzzle !
The first logic steps are quite challenging, after that it's so rewarding.
Very well done, thanks for sharing.

Brilliant puzzle! Everything is so brilliantly designed. Plus the satisfaction you get once you reach the final whispers line is amazing! Thanks for yet another amazing puzzle :)

What a beast! I broke this several times before finally getting through it.

i have been looking forward to this puzzle and it was certainly a joy to solve throughout. for a whispers puzzle with only a given digit to deduce high/low parity, i especially appreciated how it does not all collapse at once. thank you Phistomefel!

Very nice break-in!

It's always a pleasure to solve a Phistomefel's puzzle; the break-in was so cool and beautiful it made me almost cry, then the deductions in later solve with anti-knight were also lovely and a bit magical too ;)
