Evens-In Odds-Out Sandwich
(Published on 14. June 2020, 16:05 by Aporion)
Hello. This is my first try at creating a puzzle so I hope it goes well.
Normal Sudoku rules apply. Additionally, the numbers outside each row/column represent the sum of the even digits inside and any odd digits outside 1 and 9 in that row/column.
Even digits outside or odd digits inside 1 and 9 are not counted toward that row/column's sum.For example, a row with the digits 251346897 would produce a sum of 30: 4+6+8+5+7.
Thanks very much for trying my puzzle.

Lately I have been seeking and solving less popular puzzles from newer constructors and most of the time find good puzzles. I didn't think I would like this one but I did. Part of the challenge is coming up with new theorems that fit the rules. Completely logical path; I didn't even have to erase (unusual for me!)
