This puzzle was made for Scojo's weekly prompt. The prompt redeemed by Calvinball, and was to create a puzzle using reflections or mirrors. I decided to do a tentropy mirror puzzle, and I hope you enjoy!
Rules
Normal sudoku rules apply.
Tentropy Mirror: Consider the digits from 1 to 9 as five tentropic groups: {1,9}, {2,8}, {3,7}, {4,6}, and {5}. The diagonal from r1c1 to r9c9 acts as a tentropy mirror. Each cell has the same tentropy as the cell reflected in the mirror, i.e. if r2c6 contains a 3, then r6c2 must contain a 3 or 7.
Region Sum Lines: Box borders divide the blue lines into segments with the same sum. Different lines may have different sums.

Solution code: Column 3 from top to bottom. (9 digits)

Very fun 3* challenge, I feel like coloring tentropic pairs makes things very smooth and approachable. Cool logic!

I thought of this combinbation a few months ago and thought "there's no way you can make a puzzle like that interesting and fun". So happy with how wrong you just proved me.
