This puzzle was the origin of 'counting circles' :)

- A circled digit indicates exactly how many circles contain that digit.

Counting circles has been one of my favorite variants lately, so it was really nice for me to solve the first one. Thank you for creating this amazing constraint, and for the quick advanced sudoku techniques lecture!

Got stuck a little, when I tried to solve the 6th number-to-go-to before the 5th. Great learning tho; usually I hate scanning - this one served me a lot on that issue.
Brilliant and fun! Thank you!

Late to the party, but glad I finally showed up! I found some of the logic quite unexpected, which to me is always greatly enjoyable :)

So cool that this is the puzzle that introduced Counting Circles! It definitely made my brain hurt, but in a good way. There's a clean solve path and so many clever surprises that I lost count (no pun intended). Very creative indeed.

I think it would be fabulous if you could come up with a name for this constraint :) It definitely has considerable potential!
Reply: Thanks for the comment :) These are called 'Counting Circles', and I'm glad to see quite a few people have started using that name in their puzzles already

It took me forever to figure out the break-in. After that ah-ha moment, it was sheer joy.

For some reason I wasn't thinking that the circle with arrows counted as circles.... Pretty fun once I realized they counted.

Enjoyed this a lot. It's rare enough to find a puzzle with a ruleset that's both innovative and simple, and on top of that it's beautifully executed.

Enjoyed this, the "a-ha" moment at the beginning when the break-in reveals itself is great
