Japanese Nurikabe (2)

(Eingestellt am 6. September 2022, 02:52 Uhr von KNT)

Fill some cells with numbers from 1 to 9 such that no number repeats in any row and column. All empty cells must be orthogonally connected, and no 2x2 area may be entirely empty. We call an orthogonally connected group of numbers an island. Numbers cannot repeat on an island, and every island must contain the number that is its size.

Clues outside the grid indicate the sums of connected groups of numbers in the respective row or column, in order, where empty cells serve as delimeters between groups. A question mark can be any number from 0 to 9, but no clue may have a leading zero. An asterisk indicates obscured information; in place of an asterisk may be zero, one, or multiple groups of numbers.

Clues inside the grid are empty, and the number of values inside a clue cell indicates the total number islands that appear in the 3x3 area centered at the clue cell. Furthermore, each value corresponds to a unique island and indicates the sum of all numbers on that island.

Lovely puzzle, perfect length for my train trip that very soon comes to an end. :)

Awesome puzzle. I especially liked how the opening unfolded.

Really enjoyed this! Not super difficult, but definitely a long solve - my 2 and a half hours just flew by. Thank you!

Wow, what an amazing puzzle! There is not a single deduction that is particularly hard, but it has a long solving path with quite consistent difficulty. And it remains interesting throughout the whole solve. Thanks a lot for creating this wonderful puzzle!

Wow, really fantastic! Thank you!

What a fantastic puzzle ! From the subtle break in to the final resolution, a hell of a looong ride for me, but it was worth every minute of it. Thanks to KNT for helping me spot a very silly mistake I made (not counting correctly the number of ? in a row), which led to a ridiculously long stare at the puzzle... Anyway, a joy from start to finish.

Wunderschönes Rätsel.
Der Lösungsweg war sehr "eng", aber gut zu finden.
Beautiful puzzle.
The solution path was very "narrow", but good to find.

Beautiful puzzle! Quite the journey, but well worth the time. Well-balanced, wonderful logic and very rewarding. Thank you!

Großartig. Und ein hübscher Einstieg.

Wonderful! Very consistent and well balanced, several hours of highly enjoyable puzzle solving!

Wonderful puzzle! The variety of deductions was surprising, but never felt unfair at any point. It was a true marathon of breathtaking logic.

What an incredible puzzle! This was visually intimidating for me to open, but the path was surprisingly smooth and allowed for gradual progress without any particularly brutal steps. For the first time while solving, I felt like I was part of the plot of a film, and each "breakthrough" of the solve moved the story forward. Thank you for sharing your genius!

To anyone that has attempted in the past 24 hours... I deeply apologize! I went to fix the answer check yesterday (as it came to my attention it was slightly broken) and in doing so I accidentally removed the clue in R15C13 from the link. Thank you @Vebby for pointing that out! Link is fixed.

That was a crazy solve, but in a great way! The elements combined into the opening were surprising and seeing the puzzle slowly but surely unfolded itself in a smooth way was really satisfying as well x)

Hard and long puzzle, but no step is brutal in itself. A tiring, long and enjoyable marathon.

am 6. September 2022, 13:25 Uhr von Jesper
Awesome puzzle, thanks! Very clever break-in followed by a long stream of lovely deductions with a consistent and enjoyable difficulty level

Looks intimidating, but it really does have a very smooth solve path. Great puzzle, 3 hours well spent for me!

When transcribing the puzzle into Penpa+, I accidentally omitted a "5" clue at the top of the Japanese Sums in C10. Image and link fixed. Apologies to anyone if they started it before I made this change!

My favourite puzzle of yours to date; a joy to solve from start to finish! Brilliant balance between the different rules and a much smoother solve for me compared to #1. Really hope people aren't put off by the big grid on this one & give it a go. I look forward to seeing what you come up with next ;)
