Islands 4: Chaos Theory
(Eingestellt am 13. März 2024, 20:00 Uhr von SamuPiano)
I’m back to setting with my favorite ruleset!
Rules:
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 (REGARDLESS OF TYPE) and must sum to the number in the top left corner of the cage.
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.
Cells separated by a white dot are 'harbours' - the pair of cells connected by the dot contains exactly one island and one ocean and the digits in these cells have a difference of 1.

Happy solving! Please do leave a comment if you enjoy!

Terrific puzzle. I just solved the entire Island series, they're all great but this one was my favorite.
When solving them all in a row, there are interesting comparisons that emerge. I can't say more without spoilers. :)
Thank you so much for persevering through all the puzzles! I really appreciate it :) I would love to know more of your thoughts. If you have Discord, my username is SamuPiano :) -SP

Emphasized regardless of type in the rules.

And finally this puzzle sailed into the harbour safely. It's a great puzzle, loved to solve it several times. With every time it got just more interesting. :)

I absolutely love this series, and this is no exception. Somehow I missed #3. I'll have to go back. Thanks for the puzzles!
