Hi, I have recently picked up Star Wars battle of Darth Vader, and I’m a little worried that the payout isn’t working. My old 2006 starwars pays out every time a ball goes I the start hole, normally around 4-6 balls. This new machine doesn’t pay anything when a balls drops in start and spins. Is this normal? I’ve played for hours and never had a fever yet. Any help will be appreciated.
