Rules: Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column and 3x3 outlined box.
Digits in circles must appear in the surrounding four cells, in some order.
Also, the white circle implies that one digit is the sum of the remaining three digits at that 2x2 square. Not all circles are given, i.e. there may or may not be additional 2x2 squares where one digit is the sum of the remaining three digits.
