Quoted from goatdan:I saw that someone else already replied to this, but...
What in the world else are pinball machines meant for? I managed arcades in the past, and if our games had people playing them solid for 12-14 hours, it was a success. If they broke, but made a ton of money for the week, that was something good. The majority of our games didn't break.
I think the point that was trying to be made was that some/many games suffer from weakened flippers as the coils heat up due to non-stop play. Normally, this is not something the games have experienced out on location but yes, in some cases, they do if they get a lot of back to back play during peek hours.
I know we have seen when games were brand new this kind of issue since people were waiting with coins across the playfield glass. Let the coils cool down and everything is great again. I know there was a discussion somewhere about installing fans to cool the flipper coils on games like LOTR.
