J-Ball

The goal of J-Ball (Jezzball) is to fill a certain percentage of the screen by drawing horizontal and vertical lines. Draw lines by touching a point on the screen and swiping up/down for a vertical line, or left/right for a horizontal line. When the line is finished being drawn, any region of the screen that does not contain any balls will be filled. If a ball hits a line while it is being drawn, you lose a life. When you cover enough of the screen, you advance to the next level. Every 4th level adds an additional ball and grants a free life.
