In fact, all the fun of Super Balls begins when you learn the secrets of the bonuses, how to get and use them. 

Obviously, it is not so easy, but you will certainly succeed with a bit of skill and luck. In this example, "DELETE" key deletes all blue balls, and you're ready to create another bonus.
Like on the screen above, putting the selected purple ball in the field with a pointer, you'll get one of the most important bonuses  "Three black balls", which can replace any other ball in any color. For example, when you have a row with four green balls, adding a black ball makes them disappear (except the black one, which can be reused.)
An added violet ball makes all three rows of violet balls disappear, since it creates the required minimum of five balls in each row.
ABOUT THE BONUSES:
Random bonus  for 6 balls you'll get a "?" sign, which means that you have a small chance of getting a bonus, if you make six balls in a line once again, you'll get "??" sign and your chances are fiftyfifty. For the next 6 balls you'll get "???" sign and your chances of winning a bounus are very high.
