Lighthouses Nurikabe #2

(Eingestellt am 12. Januar 2023, 01:08 Uhr von KNT)

...And now for the main course!


Divide the grid into island cells and water cells. The water is all connected, and contains no 2x2 area. Every island contains exactly one number that is its size.

Some ships are to be placed in the water. If a number is in a water cell, it is a lighthouse, which indicates the total number of ships that share a row or column with that lighthouse. Ships may not touch each other, or lighthouses, even diagonally. Lighthouses may only touch other lighthouses diagonally.

Note: Every hint is "knapp daneben", i.e. too large or too small by one.

The puzzle can be solved online here.

Answer check is enabled with grey shading for water cells, and stars in composite mode must be placed at the location of each ship. The star battle tools that Penpa+ provides will be useful for this puzzle. I also recommend marking the possibilities for ship counts in the margins of rows and columns.

Lösungscode: Row 1 followed by Row 5, S for ship, L for island cell, and W for water cell.

It is such a pleasure to see older (and mostly forgotten?) tags being used again, and of course wonderfully executed as I would expect from you.

The KD is a lovely addition to the ruleset and was a really fun & enjoyable solve. I'd certainly vote for solving another.. Perhaps with a loop next time? ;) Thanks.

Star battle scanning is the bane of my existence. The logical path is very satisfying though :)

This puzzle is quite tricky, but I think if you give it the time and notate it carefully, you will find it one of my more rewarding creations. I don't intend to set any more of these, but if people do solve this and enjoy the puzzle/genre, I am happy to make further substantial variants. Enjoy :)
