Nice puzzle. Thanks for setting. I completely forgot about palindromes only containing odd digits, but solved it anyway. Perhaps this constraint is unnecessary?

Nice puzzle! But please add the clarification, that 5s must be adjacent to ONLY odds, to the rules. I had a double solution case at the very end and just experimented to see which one is correct.

I struggled with this quite a lot until I realised I had missed one small detail in the rules, about palindromes being odd, doh! A clarification on the 5's rule would be helpful too, I checked the comments to get that one right.
Otherwise a nice puzzle, thank you :)

Idk why but I absolutely loved this puzzle. Probably one of my favorites you've published!

I've always thought 5s miss out. Not allowed on Vs and Xs, not invited to German whisper lines. I'm glad you have given them the recognition they deserve!
Similar rule restriction to a puzzle I published yesterday. Great minds think alike (and fools seldom differ!)
Thanks for the fun puzzle. :)
- I attempted to solve your puzzle, Even S7evens, ( https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000CXG ) and unfortunately was not smart enough to get the break-in, but I absolutely loved the concept of it. You're puzzle was the inspiration for me to build this one. I'm honored that you enjoyed my offering. Thanks for the kind words and thanks for playing! - Tingo

Small rule clarification request: Must all 5s in the grid be orthogonally adjacent to ONLY odd digits or just to multiple odd digits?
- Only odd digits. If a cell is orthogonally adjacent to even digits, it cannot contain a 5. - Tingo

Nice. But, as others have experienced, CtC reports the solution is correct, but the solution code here does not match
- My apologies, this should be resolved now. - Tingo

Should I write it here in the comments?

code?
on 12. February 2023, 09:29 by Briks
I'm sure I've got the solution but it is marked as wrong.
- My apologies. I had a typo in the solution code on the page. It should work now. Thanks for playing! - Tingo
