Proximity of Oblivion
(Published on 2. March 2023, 06:00 by XeonRisq)
- Normal sudoku rules apply.
- Proximity Cells: The digit in a square cell designates how many surrounding cells are of the same parity (odd/even).
- The digit in a circle cell designates how many surrounding cells are of the opposite parity (odd/even).
- (The proximity cell is not counted in the total for the surrounding cells.)
- Oblivion Cells: Exactly one oblivion cell will exist in each row/column/region, and will be a unique set of the digits 1-9.
- These cells do not count toward the odd/even count for any circle/square cells they are touching.
- If an oblivion cell is in a circle/square cell, then the proximity rules of the cell no longer apply.

First Xeon puzzle. Very entertaining and made me think differently about "counting" cells. Thanks Isaiah. Great puzzle :)

Just wow. Small logical steps rule out certain candidates at the right places and after that very smooth. Thanks for this.

You are quite welcome and thanks for the feedback. Glad you enjoyed this one. It's an interesting twist on sweepers with an added twist of oblivion.

@XeonRisq - a query pl, in case of an oblivion cell being on a circle/square (the last rule bullet), the count rule not applying means such a cell canNOT have the correct count of its neighbours, or merely that it does not HAVE to be the correct count ? Thanks.

It means that it does not have to be correct. In essence, it means that it is no longer a square or circle AND it does not contribute to the count of any proximity cell it touches.
-Thanks for your response. :)
