The object of this game is to fill in at least three quarters of the board. Any closed region with no balls inside will be automatically filled, so you accomplish your goal by cutting off empty areas of the board.
Move the mouse over the board, you will see either a horizontal or vertical line. Click the right mouse button to switch between horizontal and vertical. When you click the left mouse button, the selected line will be filled in.
You are not allowed to hit any of the balls, and also the lines don't fill in instantly. If a ball hits your line before it's finished, your line will be cancelled, and you'll lose a life. Once a line is completely drawn, it's safe.
When you fill three quarters of the board (there's a counter to tell you how you're doing), you'll get a nice bonus to your score, and you'll be moved on to the next level.
