You don't hear Show Boat mentioned a lot when talking Gottlieb wedge heads. I personally love the game and its playability, even though it's underrated and not a lot of collectors favorite wedge head.
The game gets overlooked because of the four flipper arrangement, which seems to make the average player feel uncomfortable on when to use the flippers. The flipper arrangement take some getting use to at first, but can be master after many hours of practice playing the game.
I thought to send this link to describe game play and to kind of give Show Boat a chance to show off what the game offers the player and of course to give Show Boat the recognition it deserves.
