Entirely symmetrical except for one little clue. That means the solution ought to be mostly symmetrical too… right?

Very fun. I was struggling a bit until I counted the givens. It was quite simple after that.

Warning: Miscounting brings disaster. I miscounted it a few times before… xD (But now I counted correctly, and the puzzle has (quite unexpectedly) a unique solution.)

Um… Is it possible to do this without the center two givens? My intuition says so, but I haven’t tried it…

No. A single 36 can run around the outside.

A full ring is 36. Take off 3 in the bottom left corner. Another forced square at each of the bottom left and top right. There are several options for the last square of the 36, and many options for the remaining squares.

Yes, making sure that there can’t be a single 36-omino was a key step in the logical solution, so I believe you need every pair of 36s.

very interesting, first count, then it is clear, what is missing, and then the solution begins in the lower left corner. this is one of my top ten fillominos
thanks and regards from Germany

Very nice. Brilliant and unique first step of realizing that a single 36 is impossible, then seeing that the givens add to 99 and placing many 36s from there.
