Quoted from yancy:Over a couple long games I wasn't able to figure out which shot(s) feed the upper PF to get ready for the bookcase flipper. Started holding my left flipper up every time I hit a hidden shot, just in case.
I've not played the game or looked into it/watched anything at all since the reveal, but isn't there just 1 big fat ramp right in the middle that feeds the upper PF, and that's it?
