Quoted from Chicoman:Ocktoberfest is poorly designed and it's impossible to keep the ball in the upper half of the playfield.
Serious question, aren't all pinballs by design "impossible to keep the ball in the upper half of the playfield"? What exactly do you mean by this. Unless there's an upper playfield with its own set of flippers, just how is one supposed to keep the ball in the upper playfield??
As far as the OPs question, Oktoberfest is a blast when set up properly and given some time to learn the objectives of the game.
