5ball is similar to klines, but bigger (and meant for at least 1024x768 screen res.). It includes many options such as different board size, number of different colors, undo, different themes, etc. The object is to make a line of 5 like- color balls which will eliminate them from the grid. Score as much as you can before the grid fills. 3 new balls are placed randomly on the grid each time you move without making a line.
