- Each number is a run of filled squares in that row or column, in the order given.
- Runs are separated by at least one empty square.
- Fill the squares you can prove, and mark the ones you know are empty. The picture is named when you finish.
Drag along a row or column to fill or mark several squares; undo takes back the whole drag. Keys: ←↑→↓ move, F fill, X mark, T switch tool, ⌫ clear.
