Does the game have a multiball? I can’t remember if it does. If it doesn’t, it should only have one ball, but watching a video of the game, when you lose a ball, it kicks it into a trough. It would have no need to kick the ball into a trough if it only had on ball, so it could have 3. Gottlieb did weird things like that like putting 4 balls in a game that only has a 3 ball multiball.
