Are Circles and Squares Pals? (Sudoku)

(Published on 19. July 2021, 14:16 by PDN777)

Normal sudoku rules apply. Digits along the palindrome line must read the same forward and backwards. The circle cells form a complete set of the digits 1 to 9, as do the square cells. Digits in cages sum to the little number at the upper left of the cage, and may not repeat within each cage. Comments welcome!

Fun puzzle! I liked how the circles and squares resolved.

Edit: yes I really like those types of extra regions too. I'm glad you enjoyed!

Edit: Wow! That's wonderful. Congrats on "leveling up." :-)
