Simple and fun Very simplistic design with black and white Tap to switch between two dual modes Collect balls in the correct mode Avoid same color balls which will be invisible 3 lives to try out your ability to juggle between This game needs maximum attention If you blink too much you will fail When you get bored just play with Dual Balls… Pun not intended http://play.google.com/store/apps/details?id=com.Yigotech.DualBalls
