Sudoku Variants Series (377) - Little Palindromes Sudoku
(Published on 27. July 2022, 02:00 by Richard)
Little Palindromes Sudoku
This puzzle can be solved in a complete logical way, but contains a few tricky steps. I have written those steps as a hidden comment, for learning purposes.
Inspiration for this type comes from tzael
Solve online in Penpa+ (thx Henrypijames!) or F-Puzzles or CtC-app (thx Nick Smirnov!)
Apply classic sudoku rules.
Clues outside the grid indicate the sum of the digits of a palindrome, that is located somewhere in the diagonal direction of the arrow, and consists of at least three digits.
Solution code: Row 9, followed by column 7.

Wunderschöner logischer Pfad. Ich konnte es genau so lösen, wie von Richard beschrieben.
Für mich mittelschwierig.

@Henry and Marc: I found some deductions pretty hard to spot, so set it to an initial rating of 4*. The current rating is close to 3* though...

nice puzzle. I made a mistake with logic first time but then went back and was able to solve it.

Only 3 difficulty for me (pretty much along the intended path). Weird that the puzzles you rate 3 or less I rate higher, but the ones you rate 4 I rate lower. :D

@bigger: I don't know, but it's written more as an encouragement to proceed solving and search for the next logical step. I have tried some blue-star-sudokus recently and got stuck, even while the authors have set the initial difficulty at two or three stars. I have put those puzzles aside, but it would have helped me to know if it could be done without bifurcation...

Sparsame Hinweise :-)), aber sie weisen auf den logischen Weg. Sehr schön!

just out of curiosity, how to solve this in an illogical way?i don't see any significantly speed boost in brute forcing any clues. using clues isuch faster.
