my two highest scores...
I haven't been anywhere over 182 aside from the 192.
I've gotten 182 two times, 181 maybe 5 times, 180 over 10 times.
My trick is:
1st swing get 2
2nd swing hit the pinata on its way away from you to get 10 total pts
3rd swing hit the pinata away from you again for a total of 26 pts
from then on, just hit the pinata as close to the edge as possible on it's way down (or towards you)
