Modular Islands
(Eingestellt am 23. März 2026, 21:54 Uhr von Killer Joe)
Hello.
Normal Sudoku rules apply.
Digits are grouped into modular sets:
mod 1 → {1, 4, 7}
mod 2 → {2, 5, 8}
mod 0 → {3, 6, 9}
A digit placed in a circle indicates the size of the orthogonally connected group of cells that all contain digits from the same modular set as that digit.
No group contains more than one circled cell.
Not all groups contain a circle.
Digits separated by a white dot must be consecutive.
Have fun.
Lösungscode: Row 9, first 6 digits.

Fun coloring puzzle, and more straightforward than it seemed at first glance

Changed 'regions' to 'groups' for clarity.

The constraint is so strong it practically solves itself.

That was fun! Looked confusing at first then the constraints started to become clear. Good job, thanks.

I've been playing a lot of The Artisan of Glimmith recently, and this puzzle reminded me a lot of it. I found both the Pen and Coloring tools useful as I made my way across the grid.
