Rules: Place a digit from 1 to 9 into each empty cell in the grid so that each digit appears exactly once in each row, column and 3x3 outlined box. Additionally, clues next to the grid give the sum of the first two digits seen from that direction, labelled A and B. Clues in the grey band further outside the grid give the sum of the digits in position A and B for that row or column.
