Normal Sudoku rules apply.
Killer Sudoku rules apply. Rotationally symmetrical cages sum to the same total (E.g. The two cages in column 5 have the same total, and the cages in column 2 and 8 have the same total.
Sandwich Sudoku rules apply. Digits outside the grid show the sum of the digits sandwiched between 1 and 9 for that row or column.
Digits in a circle are surrounded by 8 different digits.

Very original puzzle with many hard but fair and very neat deductions. Loved it!
Apologies for making a puzzle with (almost) the same name!

The circles tell a story which is not really apparent at first, but then they really open up! Wonderful puzzle!

I got hooked by this new constraint.
This was really fun and unusual to solve, and this very simple circle ruleset is very inspiring. Thanks for the puzzle, PrimeWeasel !

Raised the difficulty to 4 stars, it's somewhere between 3 and 4 I'd say.
