Quoted from EEE:
Not sure that is correct, It is the second ball that will collect the Big Bang up the left ramp, and after the first ball is successfully locked up the left ramp by enough saucer or back to bop shots.
Ive played pz a trillion times, archieved the big bang countless times, i can safely say that partyzone stick with only two ball multiball. The big bang bar can only be archieved by getting 1 maximum rocket fuel jackpot then the white big bang insert lights up.. Head for the rocket!!! And u lock 1 ball up and the 2nd ball will award u the big bang jackpot ,which can be up to 99.999.990 million maximum i believe haha
