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.

That was quite a challenge! Very nice, but 4* difficulty imo.


@Steven R, thanks! I changed the difficulty based on your feedback.
