Islands
(Published on 7. December 2021, 04:52 by SamuPiano)
This is a 9x9 map of the ocean - there are ocean cells and island cells.
Normal sudoku rules apply.
Killer sudoku rules apply - digits cannot repeat within a cage and must sum to the number in the top left corner of the cage.
Kropki rules apply - digits with a white dot between them are consecutive. There is no negative constraint.
HOWEVER, 18 cells - two in each box, row and column -are "island" cells - these do not count toward the cage totals. Only "ocean" cells count towards cage totals. There can be as many island cells as needed in any cage.
Happy solving!
Solution code: Row 8 of the solution.

Thank you for this fantastic puzzle, SamuPiano! It seemed so intimidating at first, but the more ocean and islands I got the more I could accelerate my solving speed. While being very challenging, everything kept on giving. Superb setting!

This series came highly recommended and with good reason, I can see. Incredible idea and incredible execution.

That was great fun. Having to place 2 islands in each set (instead of just one) leads to many interesting situations. I'm looking forward to hopping along to your other Island puzzles. :)

Neat puzzle! Took a fair bit to solve, but didn't feel totally impenetrable like some of these more unique constraint puzzle do sometimes. Awesome job!
