Easy Peasy Sudoku Advent (19) - Little Palindromes
(Eingestellt am 19. Dezember 2025, 06:00 Uhr von Richard)
Dieser Sudoku-Adventskalender enthält 24 Varianten, die in meiner Sudoku Variants Series (SVS) enthalten waren, sich jedoch als zu schwierig erwiesen haben, um von einer breiten Masse an Rätselfreunden gelöst zu werden. Ich strebe einen Schwierigkeitsgrad von 1 bis 2 Sternen an und habe auch einige allgemeine und/oder spezifische Hinweise geschrieben.
Little Palindromes
Algemeiner Hinweis:
Ein Palindrom mit einer ungeraden Summe hat immer eine ungerade Länge und eine ungerade Ziffer in der Mitte.
Der Hinweis 3 bedeutet drei 1er hintereinander.
Ich hoffe, dass einige Rätsler nach dem Lösen der Adventsversion das ursprüngliche SVS-Rätsel #377 ausprobieren werden.
Verwende die üblichen Sudoku-Regeln.
Hinweise außerhalb des Gitters geben die Summe der Ziffern eines Palindroms an, das sich irgendwo in der diagonalen Richtung befindet, die der Pfeil anzeigt, und das aus mindestens drei Ziffern besteht.
Beachten Sie, dass das Palindrom nicht unbedingt in der ersten Zelle in Pfeilrichtung beginnen muss!
Der Hinweis 46 deutet auf zweimal 23 = 6,8,9 in den Feldern 6 und 8 hin.
Nun kann R4C9 nicht Teil des 7-Palindroms sein, und zwei der Ziffern, die Teil davon sind (R2C7 und R3C8), sind aufgrund der platzierten 1en in C7 und C8 minimal 2 und 3.
Lösungscode: Spalte 9

Einfach nur genial! Wenn ich alle Kalendertürchen offen hab' werde ich die nächsten Monate in den schweren Varianten verbringen!

Thanks for your kind words Tws!
That is exactly one of my goals; interesting players to solve a bit more 'obscure' sudoku variants that force you to think a bit different than with the usual variants. :)

The puzzle is very nice. Tq.
But I do agree the solution checking will help for players with less confidence like myself. In some cases when the rules are complicated, I also use it to try and confirm my understanding of the rules.
Tq for the great puzzles, Merry Xmas.

It stresses me out so much when a puzzle doesn't have solution- checking. I'll come back and start the puzzle when a solution-checking version is posted in the comments, anybody, please?
Edit: I'll attempt it anyway, but just so I can express my opinion with a low rating.

Thanks for your comment Decapod, although I am really in shock! What a childish behavior this is. If the solve link with solution checking is published, I will hide the comment; since the players before you, didn't have that possibility and that's not fair too.
But your comment means other things as well. The beauty rating of a puzzle than doesn't actually reflect the beauty of the puzzle itself, but does also include a meaning about the presentation of a puzzle.
I suspected earlier that this kind of rating bevahior was going on, and it really hurts me as author who spends hours and hours writing puzzles that can be solved by the puzzle society for free if players approach it like this instead of being thankful what they received.
But the power is obviously with the players. They decide in the end where a puzzle ends up. Ignored, solved often, low rating, high rating... It makes me sad that authors/me are more or less forced to enable solution checking, which has not so much to do with solving a puzzle in my opinion.
But since this issue is activated a few days ago, I have let my thoughts go over it and decided that the last five days of the calender will have both; a version with and one without answer check.
I wish you a merry Christmas.

Accidentally made the puzzle a bit trickier for myself by forgetting that palindromes need to be at least 3 cells long (otherwise the 18 and 14s could be pairs of 9 and 7 respectively).
Really interesting! I enjoyed it from start to finish.

Really liked this puzzle. I wanted to let you know that I appreciate you keeping solution checking off, as it has helped me slow down and be more thorough in my reasoning in other puzzles as well as yours.

I already had solved the original, a fantastic (and hard) one. So I really enjoyed the walk through this beautiful and approachable appetizer. Thank you very much for creating and sharing this lovely puzzle.

Very fun puzzle, thanks!
At the start I wasn't sure if the digits had to be consecutive in the palindromes or not, but was able to figure it out along the way. Nice constraint!
