Balloons N More

i cannot get past it. I think it has something to do with freezing the balloons on the right, then it bounces to hit the ball with the bomb in it, but I still need to get 3 balls No more features are exhausted, even Dart unlimited mode i cannot get even more balloons. This may seem sad but im Curius on how to fill

Umm
I think that on youtube if you type Bloons level 30 is a video showing you how to fill it.
