Although it's a totally different game, I've always loved this video for learning about ball control:

It's not pinball related - just some classic hardcore punk music. https://www.dischord.com/release/003/1st-7

Good point. I think it's about balance when you're first starting out. I used to spend about 50% of my time practicing, like trying to hit the same shot over and over. And I'd spend the other 50% just playing games, incorporating my new skills.

The multiplication effect is so accurate. I started collecting less than a year ago with just one pin. Since, I've purchased a total of six! Three of them I've sold. It's such a fun hobby.

It's been a while since you posted @lucysuros. Are you still as enthusiastic about pinball?

So glad you're loving Pinball! You now have 2 games, up from 1 just months ago. Will be interesting to see how many you have in the coming years.
