Hello.
this puzzle turned out to be a bit tricky for some but it has some nice geometry. (not Phistomefel's ring)
If you get stuck, consider the cages from box 5 and how they interact with the other cages.
Testers agree on 2 stars for difficulty but I feel like it's closer to 3. Let's find out...
Normal Sudoku rules apply.
Digits do not repeat within a cage and each cage sums to the same total.
The digit in the grey square is even.
Consider the grid as concentric layers centered on R5C5:
Layer 1: R5C5
Layer 2: the remaining cells of box 5
Layer 3: the ring of cells surrounding box 5
Layer 4: the next outer ring
Layer 5: the outermost ring of the grid
In each layer, all caged cells have the same parity (all odd or all even).
Have fun.
Solution code: Row 9, first 6 digits.

Definitely a 2*. Very fun, too! It was nice, being able to smoothly reduce my colors down to just odd and even.

looks very hard, but careful, judicious goodliffing reveals a surprise

Fantastic, lots of surprises. I think I agree with the testers 2* difficulty.
