I don't know if it was intended but I ended up adding up the shaded cells in so many different occasions that now when I see more than one number at once anywhere anytime I end up calculating their sum without even meaning to. My coworkers send their gratitude for turning me into an organic calculator.
On a serious note, this was a very fun and unique puzzle. Difficulty is most likely 3-4 stars.

I'm sorry to have caused this, it was never really my intention! In fact, it is possible to solve the puzzle logically without summing up any of the digits in the shaded ring.
Thanks for the feedback!

Very nice puzzle, thanks a lot! I think about 3 stars. I don't know why people don't solve it more :)
