Statera (159, Quad Sums)
(Published on 30. September 2025, 07:00 by Crusader175)
Normal sudoku rules apply.
159: Digits in columns 1, 5, and 9 indicate the column in which the digit 1, 5, or 9 (respectively) appears in that row.
Quad Sums: A circle at a corner implies that one digit is the sum of the remaining three digits at that corner.
Even: Digits in grey squares must be even.

I found a 6/7 pair partway through and got really curious as to how it would eventually get eliminated, since all the clues that directly saw it eventually got filled out. Pretty neat to see it finally resolve.
