Lighthouses Nurikabe #1
(Eingestellt am 8. Januar 2023, 07:48 Uhr von KNT)
Rules:
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.
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.
Lösungscode: Row 6, S for ship, L for island cell, and W for water cell.

Great puzzle, thank you. The scanning is definitely tough, but the lighthouse logic was really satisfying to figure out.

Very nice! I didn't know about the lighthouse ruleset, thanks for this discovery.

That was awesome! It wasn't so easy for me, but a very enjoyable solve. Thank you for constructing this beauty, KNT!
Out of curiosity: Are you planning on publishing Halligen variants, as well? :)
—————————
Glad you enjoyed it :)
To answer your question: No, it wasn’t really my intention, as this puzzle was initially going to be a 10x10 example for the “real” one, which I hope is a fitting tribute to the original Halligen puzzles. The follow up is also fairly vanilla, none of that diagonal loop insanity, but it *does* have one complication that this doesn’t have, which should prove to make it more interesting. However, if people do manage to solve it and really enjoy it, I definitely would make more, and could probably come up with some interesting variations. It was particularly fun to set for me!
Also, theres a shame there are so few of these to solve. Maybe some others can provide a few more for me? ;-)

Very nice original ruleset, I imagine the next one could be quite challenging indeed!

I'm glad you enjoyed it, Magnus! And yes, the follow up is definitely challenging :). This was initially going to be the example puzzle (10x10), but I decided to extend the width and separate them. Also, this ruleset has been used by tuace 5 times in the past (can see under Lighthouses tag), and the second, or really main puzzle, is a tribute to his series, which is absolutely incredible and I recommend hugely.

This puzzle is beautiful! Really elegant use of an elegant ruleset. A good variety of deductions make use of different aspects of the puzzle so it feels refreshing and holds your interest even if you're like me and get stuck sometimes!
