For anyone having trouble scoring more than 20,000,000 or so, or anyone who has issues with the ball getting stuck by the pops, I’d check the pitch.
At 6.8 I don’t get nearly as many side drains since the ball is less floaty. I also don’t have issues with the ball getting stuck in the pops anymore.
I had it there when I was hitting highs of 80,000,000 but reverted back about a month ago and hadn’t cracked 30,000,000 since I did that. After going back to 6.8 and a fresh side to side level, I’m consistently hitting 40,000,000+ again.
I can’t stress enough how important boosters and patches are either. Study the patches and what they do and what patch combos do. For example, as other have said, Fender patch makes band frenzy much easier to achieve during a song and you need that active, and send balls to the pops while active, to really build your jackpot.
Try to avoid Rocket Queen until you have the condom patch, try and do Welcome to the Jungle after you have the gun and rose patch.
I also like to get the 4 sponsor patches early on - not only for what they do individually but once you get all 4 you are awarded an extra ball you can try to collect.
There’s little reward in giving it hell trying to play a song for points if your song level is 75 or lower - you’ll work your ass off and barely get a few million.
If I accidentally start a song before I am ready to because I know my song value is not high enough then I will just play the song as long as I can to try to cash out when there is an extra ball award to collect.
