Quoted from holminone:
Great info. Can you explain a bit more what you mean by collecting hidden bandmember items through the tour? Do you mean the patches or something I’m just completely oblivious to?
I might’ve triggered something last night because my jackpot and I forget which song ballooned from 2,000,000 to 15m pretty quickly and I don’t know what I did. The best part is I hit the center scoop when it was green towards the end of the song and while the ball was still in the scoop applause jackpot lit and I received it. Very satisfying!
Sure, the hidden band member items are pretty hidden actually. One of them from what I can remember is the mystical antlers. The way you collect them is by touring over and over again (hitting any of the lit loop shots) until you start the on the road mode. You can refer to the rules flow chart here under the rules section http://marketing.jerseyjackpinball.com/gnr/JJP-GNR-rulesflow_rev2.jpg
It's hard to gauge when you collect them, but if you watch someone else play or look up every time you hit a tour shot on the road you might see it.
As for your jackpot score moving quickly, you probably got into band frenzy mode. That's honestly the best way to build a jackpot. The fender, Vader, and Duff patches help build that the best if you collect those first.
Hope that helps!
