This is a sophisticated version of Zuma. As well as in Zuma balls of different colors move along the paths. You must not let the balls line reach the end of the path. To do it you need to throw balls into the line and try and form groups of three or more identical balls. In this game you not always throw the balls from the center, but sometimes move a pad with a ball in the bottom of the screen ala Breakout. You can also shop for upgrades in the end of each level and throw a wide array of special items from your cannon.
