Rules:
- Normal Sudoku rules apply
- Copy Cat cells:
- Exactly one cell in each row, column, and box is a Copy Cat cell.
- The digits 1-9 each occur exactly once in a Copy Cat cell.
- The value of a Copy Cat cell is the digit (not value) from the rotationally opposite cell in the grid.
For example, if R3C4 is a Copy Cat cell, then its value is the digit from R7C6.
- Dutch Flat Mates:
- Every cell with a value of 5 must either have a cell directly above it with a value of 1, or a cell directly below it with a value of 9.
- HOWEVER, in THIS puzzle, the digit 1 can never occur directly above a cell with a value of 5, and the digit 9 can never occur directly below a cell with a value of 5,
- ...so the Dutch Flat Mates constraint must always be satisfied with Copy Cat cells.
- Circles:
- The value in a circle is the distance to a Copy Cat cell in the same row or column as the circled cell.
- All possible circles have been given.
- Dutch Whisper Lines:
- Values of cells occurring sequentially on a Dutch Whisper Line must differ by at least 4.
- Kropki Pairs:
- Black Dots separate values in a 2:1 ratio.
- White Dots separate consecutive values.
- Not all possibles dots have necessarily been given.

Quite tricky, but interesting logic. Very satisfying to solve.
