I picked up my project Casino in a bulk buy. Unfortunately, it's still on the todo list, but I just recently got a chance to play this title for the first time at the Pinball Hall of Fame (PHOF) in Vegas. My first reaction is that I really need to get mine working (although I doubt it will ever look as nice as the one at PHOF). I was afraid that the dual spinning discs would make this game a luck box, but fortunately that was not my experience at all. The discs do change the trajectory, but I felt it was largely predicable and controllable with skilled nudging.
Is this the only game combining a center up-post, a left outlane kickback, and a right-outlane save gate? It sounds unfair, but even with all three active, the "Down Post" rollovers are strategically positioned so that you can never get too comfortable. Also, I think the copy at PHOF was leaving the ball gate open after use, but my understanding is that it should reset after use and you would need to re-open it, which seems more balanced to me.
Now, let's get to the elephant in the room. The handwritten description card at PHOF calls Casino (June 1972) the "poor-man's" Fireball (February 1972). I feel it is unfair to compare the two, but let's discuss. Likely, the dual spinning discs were at least inspired by Fireball's single spinning disc, but so were many games since. Casino then goes over the top with the above mentioned trio of ball save mechanisms. Another similarity is three pop bumpers, but that doesn't exactly break any new ground. However, Casino falls short of Fireball in regards to multiball (nope), captive ball (nope), devilish skill shot (nope), zipper flippers (of course not), and iconic theme (although Casino's artwork and especially the backglass is charming in it's own way, it simply cannot compete here with Fireball). Note that with no multiball there is also no ball stealing in Casino which may give it a multiplayer edge in some views. Casino may also come out on top when considering value as Fireball is likely north of $2K for a decent example and I would guess the much rarer Casino (with 10% of Fireball's owner numbers on Pinside) to go for half or possibly less.
In short, Casino should be appreciated on it's own. It's a solid entry from a company with a long history in pinball, but by this point in time was certainly a second-tier pinball manufacturer that dabbled in pinball when compared to the quantity of titles being shipped by Bally, Williams, and Gottlieb and in less than five years would become Stern. If you get a chance to play one in good condition, it is certainly worth your time. I'll update when I have mine functional, but I feel this game should not be overlooked.
