How to Destroy Opponents Defenses
I’m starting off with Balloons simply because they are usually the
simplest to comprehend. Simply because they aim for defenses and fly
(disregarding walls and other hurdles) their route is very easy to
estimate. All there is to understand is that right after being positioned;
they will attack the closest defensive structure. Once that defense is
dead, they will go to the next closest.
Some bases are incredibly simple to anticipate since there is always a
“next closest” tower that's very easily recognizable. The following is a
good example base that is somewhat simple to anticipate where the
balloons are likely to go. The circles are the spawn points, and the
balloons will follow the burgundy path in the indicated course as a
result of next closest being where it is. But this gets more difficult in
some bases. This is a method of practice/testing yourself.
