Rules:

Normal sudoku rules apply.

Index Lines:

  • The value in the Nth cell along a line (starting from the diamond) indicates the position along the line where the value N appears.
  • For example, if a diamond cell has a value 3, the third cell along that line must have a value 1.
Self Reference Lots:
  • Digits in a circle count how many cells (including itself) on that line reference themselves (in other words, the digit in the Nth cell on the line is the digit N).
  • For example, 3214 with the 3 on the diamond could have the 2 be circled, because there are 2 digits referencing themselves (the digits 2 and 4 are in the 2nd and 4th place respectively).
Black Kropki Dot:
  • The black dot separates digits where one is double the other.

All feedback (positive or critical) appreciated!

Solution code: Row 9, from left to right 9 digits

This was a hard one, though I think I have found (some of) the fundamental conclusions soon. I gave 4*, and now I feel exhausted - and satisfied! Thank you very much for creating and sharing this fascinating puzzle.
