In the grid, some cells are to be blackened in such a way that exactly two cells are blackened in each row and each column. In the remaining cells, the digits from 1 to 6 are to be entered in such a way that each digit occurs exactly once in each row and column. The numbers outside the grid indicate the sum of the digits between the two black cells.
Blackout: Within the grid, cells with digits may also be blacked out; these are then considered black cells.
Solution code: Row 3 and column 6; X for a black cell.
