| Pattern | |
| <p> | |
| Fill in the grid with a pattern of black and white squares, so that | |
| the numbers in each row and column match the lengths of consecutive | |
| runs of black squares. | |
| <p> | |
| Left-click in a square to mark it black; right-click (or hold Ctrl | |
| while left-clicking) to mark it white. Click and drag along a row or | |
| column to mark multiple squares black or white at once. Middle-click | |
| (or hold Shift while left-clicking) to return a square to grey | |
| (meaning undecided): dragging like that can erase a whole rectangle, | |
| not just a row or column. | |
