Quoted from BRW84:
Last night, my Barracora started ending games after the first ball. It doesn't matter if you're playing one player or four, the game ends after the first ball drains. I thought it might have something to do with the trough switches, but everything seems fine. Could this be a board issue? I've got a Rottendog board installed.
I don’t know your game options, but a few months ago my Getaway was doing the same thing. Turns out my son thought it would be funny to set the balls per game to one ball.
