I had one for many years and sold it to make some room, it's a cool game for sure. One very odd thing I notice, and I bet there's not another pinball that has this "feature"... when you get a free ball by traversing through the lit horseshoe, there is no EXTRA BALL light anywhere on the playfield OR backglass... I thought that was very bizarre.... and I believe no other pinball that offers an extra ball feature excludes an applicable indication on the playfield or BG.
