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.
