For the questions on here about how the Shufflemaster (& the like) work and/or why they're so expensive.... here's the drill (yes, I'm getting old & it was over a decade ago it was all explained/demonstrated to me... but, anyway.... as memory may, or may not, serve...)
The simple Shuffletech performing your standard "riffle" simply cuts the deck in two (approximately, it's no where near perfect), & then fires those two halves toward each other into a central tray. (you can watch one work on YouTube... do a search). Not only is it not perfect, it's rather dumb as well. It has no idea WHAT it's shuffling. Could be a Pinochle deck. Could even be baseball cards for all it knows.
Shufflemaster has a lot more going on... it is, you might say, a "smart" shuffler.
First thing it does is verify that all 52 cards are present. & not just by counting the number of cards, it scans each card to verify that each one of all 52 unique cards are present.
That test passed, it then proceeds to "shuffle" the deck.
You may wonder why I put the word shuffle in quotes. Well, before I explain that part I want all of you conspiracy theorists who swear online poker is rigged and live poker can't be to exit this topic right now.... if not, you proceed at your own risk... don't say I didn't warn you.
The "shuffling" process is (yes, really) much like online poker. The shuffler gets a "random order" for the deck via a built-in random number generator. It then sorts the deck into that predetermined "random" order.
Think all that can be done with just 600 bucks worth of parts & technology? Obvious answer.... nyet.
Not to mention that we here in recreational poker land can put up with the occasional jam or two per hour. A Casino isn't likely to be as tolerant.
Also these things have to be built to work at a near a constant duty cycle, even up to 24 hours a day maybe. Not a schedule your average Shuffletech is going to ever need to come anywhere close to.
Now think about what might be some of the costs you don't see. Like proving your RNG is truly "random" so as to get it approved by various gaming commissions & whatnot. Patent red tape, R&D, replacement units & parts on hand & ready to go, etc. Remember, you're dealing in the world of professional gaming now. Not weekend games in man-caves. That's a whole different altitude to be flying in. Having a table out of commission with a big hole in it while the shuffler gets sent out for repair isn't going to fly. So, some sort of regional support network is going to need to be in order at minimum.
And all those costs are just from looking down the rabbit hole from the surface.
10 grand?.... yea, I can see it getting there.
