Sailing with the pirates

(Published on 27. February 2023, 20:29 by sujoyku)

In the qualification for the German Sudoku Championship, I first encountered a Pirate Sudoku. I immediately liked the rule set and started playing around to build some on my own. The rules somewhat resemble entropy or whisper constraints in the sense that the digits are separated into different groups which satisfy the adjacency constraint explained below. Feel free to let me know in the comments what you think of this variant. I wish you happy solving!

- Normal Sudoku rules apply.

- Pirate Sudoku: The digits 5 represent treasures which are protected by pirates (digits 1 to 4) from commoners (digits 6 to 9). Each treasure is orthogonally adjacent only to pirates and never orthogonally adjacent to a commoner. In other words: Any digit orthogonally adjacent to a 5 has a value of at most 4.

Here you can solve the puzzle online:

Solve on f-puzzles

Solve on CtC

Solution code: Row 4 followed by Column 5, from left to right resp. from top to bottom (18 digits in total)

Tolle Idee und eine nette Geschichte mit den Piraten und den Schätzen. Hatte viel Spaß beim Lösen.

Viele Grüße Franca

Vielen Dank für deinen Kommentar, Franca! Es freut mich, dass das Rätsel dir Spaß gemacht hat. Nur um klar zu sein: Die Piraten-Variante (und die dazu formulierte Geschichte) habe nicht ich entwickelt. Ich habe diesen Rätseltyp in der letztjährigen Qualifikation zur deutschen Sudoku-Meisterschaft kennengelernt und es hat mir so gut gefallen, dass ich ein eigenes Rätsel mit diesen Regeln erstellen wollte.
Viele Grüße, sujoyku

Wow, it took me 5 attempts (at least) before I managed to solve this puzzle without goofing along the way. There must be something specially slippery with this variant rule :-)

Thanks for the great puzzle.

Thank you for your comment, phs! It is nice that you gave my puzzle a try and did not let the difficulties throw you off. Congratulations on the solve! I think that the puzzle is not very hard, but it is always a challenge to adapt to a new rule set. I learned about this variant in the qualifier for the German Sudoku Championship and liked it so much that I wanted to set such a puzzle myself. I am glad that you enjoyed the variant as well.
Kind regards, sujoyku

Quite easy, but real fun! Thank you.

Hey Arlo Lipof, thanks for your comment! I thought I first upload an easy one so that everyone can get used to the variant. I might construct a harder one (or some mix of a Pirate Sudoku with other variants) in the future.
Kind regards, sujoyku
