Summary

Key Claims

• OnBeam has stackable extra balls—you can earn multiple extra balls by repeatedly hitting the lit special target

  high confidence · Host explains: 'You can stack extra balls, and more stars turn on. So you can still try to earn another extra ball.'

• OnBeam uses mushroom bumpers (pop bumpers) to move the spaceship, which when lined up with the space station lights the special target for extra ball

  high confidence · Hosts explain the core mechanic: hitting mushroom bumpers moves spaceship; when lined up with space station, red target lights for special (extra ball)

• Pacific Pinball Museum is open six days a week with one-pay admission for unlimited play

  high confidence · Host confirms: 'Did you know that the Next Level Pinball Museum here in beautiful Alameda, California... is open six days a week... with a one-pay admission, play all you want?'

• The museum has a gambling exhibit with velvet-roped machines that can be demonstrated by the right people

  high confidence · Host describes: 'We have a gambling exhibit on display. So these are behind the velvet rope, but if the right people are here, they can kind of fire them up and show them to you.'

• OnBeam has two-inch flippers, making it mechanistically different and harder to control than modern pinball machines

  high confidence · Hosts note: 'It's two-inch flippers. It's kind of hard to keep the ball going. Different kind of pinball.'
