Place a digit from 1 to 9 into each of the empty cells so that each digit appears exactly once in each row, column and 3x3 outlined box.
Row Sum rules: For each row containing grey circles, one circled cell contains a digit which is the sum of digits in all other circled cells in the row.
Extra Region rules: Each extra region must contain digits from 1-9. The extra regions are of 9 cells each and are shaded rectangular in the grid.
