I was at this arcade, they have 10-12 pins mostly newer. Well GB had a ball stuck on right ramp and another stuck off that ramp. The switch was keeping the ball permanently stuck. If you remove the ball on the ramp but don’t fix the switch it’ll stuck the very next ball. I showed the cashier she even took a picture of ball. Well next month I went back and it was still broken. I guess the right ramp is a bitch anyway and apparently people must still play the game or they don’t check the audits (it’s a free play arcade pay once for the day) Anyway I love pins but they can be hella problems so you’d need to fix or pay a tech to keep them running.
