Normal sudoku rules apply.
Odd/Even: A digit in a gray square must be even. A digit in a gray circle must be odd.
Close Friends: A digit in a white square must be friendly. (A digit is said to be "friendly" if it matches its row, column, and/or box number.)
A digit in a white circle must be the number of surrounding friendly digits, not including itself. (In other words, the number of friendly digits that are orthogonally and/or diagonally adjacent to the white circle.)
Not all white squares/circles are necessarily given.
Lösungscode: Enter row 7 then column 9 (18 digits, no spaces)

That was quite a challenge! Very nice, but 4* difficulty imo.
@Steven R, thanks! I changed the difficulty based on your feedback.
