Poseidon Pinball; in-depth review & gameplay

Here's a look at the rare and complex Gottlieb wedge-head pinball machine Poseidon, designed by John Osborne.
This is a superb playfield design from Osborne featuring a unique playing card and water theme. The object is collecting pairs of red and black cards to light the WOW targets for either an add-a-ball or big points depending on the setting. There's also a Mystery WOW, which can only be lit once all the cards are collected and can award up to three extra balls or 150,000 points! This is very much like a "super jackpot" on a modern machine, but rarely seen on an older mechanical game such as this.
It's also one of the most unique production examples from Gottlieb along with Hit The Deck, (the replay version), as both games are the only to feature red digital score reels and a beautiful turquoise painted cabinet. The fantastic artwork was provided by Gordon Morison.
