Nurikiller 2
(Published on 4. April 2023, 13:53 by mathpesto)
Here is a sequel to my first nurikabe puzzle. This one is much trickier than that, so consider checking that one out first if you're new to the genre!
Rules:
Each cell is either water or land. A land cell contains one of the digits 1–9, and digits may not repeat in a row or column. A group of orthogonally connected land cells form an island; islands may not touch each other orthogonally. Each island contains exactly one circle and one killer clue, and digits may not repeat within an island. A digit in a circle equals the size of its island, while the killer clue gives the sum of the island’s digits.
Water cells form one orthogonally connected region, and no 2x2 area may be entirely water. Water cells do not contain the digits 1–9. Adjacent values along a green line differ by 5 or more, and water cells are considered to have a value of 0 for this purpose.
Solve:
Solution code: Row 14, with 0’s for water cells (15 digits, left to right, no spaces)

Yes, this is appreciably harder than the first one, but very enjoyable. A few hidden traps here waiting for you to fall in...

This is majestic! It is a little bit easier than other 5* puzzles, but still there are a lot of tricky yet stunning logic in it. Thank you!

Fantastic puzzle. Got stuck a number of times throughout. Loved it the whole time. And thank you for the rule clarification.

I need a point of clarification regarding green lines in water cells. When it is considered to have a value of 0, does that mean an adjacent land cell on that green line needs to be value 5 or more?

Yes, if a water cell is on a green line, the next cell on the line must be have a value of 5 or more.

Starts off easy peasy and makes you think it'll be a walk in the park... How naïve of me ! That one took me longer than expected and was more like finding my way in the delta of Mekong ! A very nice trip again ! Thanks !
