Normal 6x6 Sudoku rules apply. Each row, column and box must contain the digits 1-6 exactly once each.
Standard Nurikabe rules apply. The grid must be filled with 'shaded' and 'unshaded' cells. Each unshaded segment contains exactly one circle. The number in the circle represents the number of cells in that segment. Unshaded segments cannot touch orthogonally, but can touch diagonally. All shaded cells form one orthogonally connected region. No 2x2 area may be entirely shaded. An an example of standard nurikabe is shown below. (Doesn't include circles because it isn't also a sudoku puzzle, unlike this puzzle.)
Additionally, each unshaded segment must contain the digits 1-X exactly once each, with X being the digit in that segment's circle. Example: In a 4-cell unshaded segment, the digits in that segment must be 1, 2, 3, and 4.
Standard Kropki rules apply. A black dot separates digits in a 1:2 ratio. Not all dots are given.
Solution code: Row 2 followed by Column 6

I give this 2 stars. Arguably one of the more difficult 6×6 Sudokus I've seen.

Very nice!
A little mistake in the CtC description: it says that the numbers 1-9 has to be placed in the grid.
