Expansion (Fog of War)
(Published on 12. December 2024, 01:19 by sujoyku)
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Fog of War: The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
- Anti-Knight: Cells a knight's move (in chess) apart may not contain identical digits.
- XV: Digits joined by a V sum to 5. Digits joined by an X sum to 10. (Not all XV are given.)
- Kropki: Digits joined by white dot are consecutive. Digits joined by a black dot have a 1:2 ratio. (Not all dots are given.)
- Arrows: Digits along an arrow sum to the digit in the circle from which the arrow emerges.
Here you can solve the puzzle online:
Solution code: Column 8 from top to bottom (9 digits in total)

I rated this 1/5 difficulty.
Fun little FoW sudoku puzzle!
I think the overall difficulty falls somewhere between 1-2/5. I tilted my rating towards 1/5 difficulty because there weren't any patterns that were too difficult, and it falls within my solve time of other 1* puzzles. I think a beginner solver who is familiar with the ruleset should find this puzzle approachable.
I really enjoyed the break-in. It used some really nice logic, and as @Karitsu mentioned, it is reminiscent of the style of @meggen033's FoW series. I'm not sure exactly what makes it feel similar in style (other than obviously showing a full unfoggy box at the beginning), but the logic itself and the techniques used are comparable. I very much enjoy those approachable FoW puzzles, and this puzzle was likewise fun!
The break-in is definitely my favorite aspect of the puzzle, but I also liked the exterior non-foggy cells that you provided at the beginning of the solve. The arrow placements were also very nice and the solve path worked out great logically!
Thanks for sharing!

You are much welcome, TheNineElements, thank you for your detailed comment! Difficulty always is subjective and depends on familiarity with things like anti-knight scanning. It might definitely be on the easier side of 2/5 here. I am glad you enjoyed the break-in and liked the arrangement of arrows and non-foggy cells.
Kind regards, sujoyku

I woke up in the middle of the night to my wife stuck in the middle of this puzzle and asking for a second set of eyes. After looking it over a minute, I gave her a hint, I was like, “What a clever trick, meggen033!” So when I opened this sujoyku puzzle this morning, I had no idea it was the same one until I got to the part where I helped my wife. All this to say, it’s an excellent setting and you did a great job mimicking meggen033’s style!

Thank you for your comment, Karitsu! I had not believed to have come as close to Meggen's setting. :D
But, all kidding aside, I am glad that you liked the puzzle.
Kind regards to you and your wife, sujoyku

Another wonderful Sujoyku puzzle! I share your admiration of Meggen’s puzzle, and I think your break-in was very much in their style. Really clever setting - thank you!

The break-in was beautiful. The second half of the puzzle took me a very long time. It didn't help that i eliminated a relevant option half way through the puzzle - but i caught it eventually.

Thank you for your comment, Gnubeutel! I am glad that you liked the break-in. I hope the mis-elimination did not give you too much headache.
