- Deconstruction Sudoku: Locate 9 3x3 regions within the grid and fill those regions with the digits 1-9 so that digits do not repeat within a row, column, or region. Cells not within a region do not contain digits, and are ignored when considering the following rules.
- Any digits in a circle are odd, and each circle contains an odd number of digits.
- Any digits in a square are even, and each square contains an even number of digits (0 is an even number).
- Triangles may contain any amounts of even and odd digits.
- The sum of the digits in any shape is a multiple of the number of digits in that shape.
- Any cell that is partially or fully within a shape is considered to be in that shape.

That‘s a elegantly looking arrangement of shapes, which slowly but steadily guide through the puzzle. Thanks for sharing.

Enjoyed this a lot :) Really makes the most of a (relatively) simple ruleset

I struggled with the first half of this puzzle, I think I counted the number of evens or odds in a hypothetical row or column dozens of times to find contradictions. I probably missed some logic that constructs the 9 3x3 faster.
