Thanks to blackjackfitz for inventing the Somedoku rule set!
***************************************
This puzzle is part of a series.
1. Friends You Can Count On
2. Somedokus Are Friendly Dokus
SOMEDOKU - Fill each cell with a digit from 1-9. In each row N and column N, there are exactly N unique digits (the rest are repeats).
IDENTITY CAGES - Digits in a cage must be the same.
KROPKI - Cells separated by a white dots have adjacent digits.
FRIEND CIRCLES - Digits are "friends" if and only if they are orthogonally adjacent to each other anywhere in the puzzle. For example, if a 1 appears next to a 7, then 1 and 7 are friends. A circled digit indicates how many friends that digit has. Note: a digit is friends with itself if it appears next to itself.
The squares outside the grid are for note-taking purposes only.
***************************************
In this example,
...2 is friends with 4
...3 is friends with 7 and 4
...7 is friends with 3 and 4
...4 is friends with 2, 3, 7, and itself
Solution code: Column 4 from top to bottom

Very satisfying break-in and ending. Love the way friendly and somedoku work together. Great puzzle :)

This was absolutely delightful and I loved every second of it. The beauty rating for this is criminally low and it isn't too terribly difficult. Thank you for the wonderful puzzle :)
On an unrelated note: I love note-taking squares. This puzzle wouldn't be more difficult without them in my opinion, but it's always a welcomed feature.

I found this puzzle quite tricky but very very good. A lot of great logic!

Yes, great to see others setting somedokus, so much more interesting logic to be had. This one was a beauty, really lovely break-in but plenty of meat on those bones even after you think you've cracked it.

Great! The break in was marvelous but the puzzle didn't fall apart until the very end. Lots of lovely questions to ask.

Thanks for this. Perfect balance of progress and roadblocks. And those roadblocks really make you think in interesting and novel ways, as is to be expected of your puzzles.
