1. Each box gets a number. The box will disappear when it's hit that number of times.
2. Look at the first image. See the white dot on top? If you can collect it, that will increase the number of ballz that you will fire in the next round.
3. I haven't figured out what the green dots are for.
I've played this about 25 times. My high score is 99. That ranks me somewhere around 4 million out of 6 million on the Leaderboard.
Good game. It's free. The graphics are outstanding. But I will not get addicted to this. Ketchapp has a string of good games!
