Clicking with the left mouse button paints a cell black. You may click on both empty cells and cells with already drawn lines to paint a cell black.

Clicking on a black cell, the coloring disappears and the cell returns to empty.

You can make turns without releasing the mouse button.

When you drag across lines already there the lines are deleted.
