high confidence · Nicholas Baldridge describing later model bingo machines
The alligator clip method for free play conversion is completely reversible by unclipping one end
high confidence · Nicholas Baldridge describing the reversibility advantage

high confidence · Nicholas Baldridge explaining free play behavior with pick-and-play buttons
“There's actually only two different methods for EM bingos to put them on free play. And it's relatively straightforward.”
Nicholas Baldridge @ 00:00 — Establishes the scope and accessibility of bingo free play conversion
“The alligator clip method is completely reversible. All I do if I want to set it back to straight up coin is to unhook one end of the alligator clip and that's it.”
Nicholas Baldridge @ N/A — Highlights the non-destructive nature of the free play modification
“If the machine immediately goes into search and just continuously searches like you're just you got a stuck coin switch, then you've got it clamped onto the wrong lug of the coin switch.”
Nicholas Baldridge @ N/A — Provides troubleshooting guidance for incorrect jumper placement
“I tend to like having my games on coin. At the moment all of the bingos are still on freeplay in my house.”
