Normal sudoku rules apply. Some cells are hidden by fog and will be revealed once certain digits are placed. Guessing is forbidden.
Coordinate Arrows: The digits on a Coordinate Arrow form a coordinate (Row, Column) of a given digit that is their sum reading from shaft to tip. There is a one to one correspondence between Coordinate Arrows and given digits.
Digits separated by a white dot are consecutive. Digits separated by a V sum to 5.
Solution code: Row 7

That break in was quite a rewarding piece of work. Also, the dynamic fog was used brilliantly. Thanks for sharing.
