Driven by a simple point-and-click interface, ScribBall is easy to learn. When a group of four colored balls touch, they will pop and an avalanche of new balls will tumble in to take their place. Quickly and strategically tap out a few balls to set up the next match even before they settle into place. If gamers are swift enough, they'll add to an ever growing combo. Injection mode puts a new spin on the gameplay, where you add new balls to make matches.
