From Evgeny EGOROV:
FireBalls is a very nice puzzle game. With beautiful scenes, nice music, and excellent sound effect, you may have fun in it. GamePlay: What you need to do is to clear the balls on the screen. Tab the screen to emit a color ball from the bottom to the top, when more than three same color balls are consecutive in a line, all these balls will be clear. The more you clear the higher score you will get.
