I will never play Blackjack in a casino environment, unless it's for negligible amounts of money.

"How dare you attempt to win one of our games!"

Then they shouldn't have the game on the casino floor. Don't get all pissy when people figure out how to put the odds in their favor.

In a much fairer way, this is what I think they should do with FPS games.. there should be a ladder, at the top are the absolute best players, they get there by starting at the bottom and scoring more than a standard deviation of points over all the other players. That way the rest of us average (or, in my case, terrible noob high ping bastard) players don't have to put up with being continually schooled. In the case of blackjack, they should just cap your bets. You wanna count cards? Sure, but you don't go off the $10 table ok?

The few casinos I have visited (around East Asia) use continuous shuffle machines with multiple decks. Seems like a far cheaper method of defeating card counters without having to confront them with big burly dudes and earning bad PR.

If you're new to slashdot, don't bother reading the article. Especially in this case, where the article is already contained in the summary here.

Las Vegas has made card-counting a non-factor. Between high deck-count shoes, variant games with unfavorable rules ("Super Fun 21"), and early shuffle thresholds, even a player keeping a perfect count cannot create a significant edge. And the million people who show up to try their hand at it and fail far make up for the cost of the few who can eek something out anyway.

The very premise of a casino is that it's a business that plays games for money. These games are conducted fairly and have public rules set out in advance. The profit comes from structuring these games such that the casino has a slight edge. Everyone knows that.

The problem comes when the casino breaks its own rules. It's a fundamentally deceptive business practice in any field to tell public that one set of rules applies, then to actually enforce another. If Blackjack is not profitable, the game should be modified or dropped. "You are not permitted to win" is not a fair rule, especially when it's a hidden rule. It's no different from rigging the odds of slot machines, and there are laws against that [wikipedia.org].

FTA: "By comparing the cards and gambling patterns, the computer can identify a card counter inside 20 hands - even if the gambler starts off with a run of high bets to confuse the system."

Yeah, right...

It doesn't take any real skill to "count cards". There are easy-to-learn systems that only require incrementing or decrementing a running total in your head. They're by no means perfect, but given a favourable shuffle they can give you an edge. The strategy is to sit there making minimum bets until a favourable shuffle occurs.

In practice, here's what happens: Casinos deal from a multi-deck "shoe", which has a "cut card" inserted toward the bottom of the stack after shuffling. The cut card is there to ensure they never deal to the bottom of the stack. (If they did, there could be times that a player could bet with absolute certainty). However, they are under no obligation to keep dealing until they reach the cut card. A competent dealer can recognize a shuffle that would play out in your favour, just as well as you can. So whenever the count starts to swing in your favour, there's no need to "send over a burly dude in a bad suit". They simply shuffle the cards!

This is what a couple of friends and me learned when we tried to play a card-counting system in Reno back in the 80's.

They brought back a lot of single deck last time I was there years ago, but in single deck a blackjack now pays 5:4 instead of 3:2. Sounds subtle to the amateur, but it's a huge hit to the player. A lot of the player's side of the math is that occasional 3:2 payoff. I can still do well with double deck with a modified single deck system, but Blackjack is pretty dead now. Cripes, they used to have prime time promotional hours where they'd pay 2:1 for blackjacks.

The whole place has lost its identity anyway. First they tried catering to families for a while, and then they went after the "high end" market- whatever. I make nearly $200K a year and the place feels ridiculous now. Vegas used to be a place where Joe Average could feel like a champ. In my dad's day they'd comp you stuff if you just stood still long enough. He once got a coupon for a free buffet at a casino he walked into just to use the rest room. True story.

Now I would not be surprised if you told me they started charging for the air in the rooms. I knew it was really over when I was walking through the Hard Rock Casino (*gag*) and saw a big crowd of people looking at something, and there was Paris Hilton in a shop (excuse me, a Shoppe- no, wait, a Boutique) trying on hats. Also true story.

Systems like this have been around for many years, and have been used commercially in various casinos. There really is nothing new or unique about it. I also see no evidence at all that it's reliable enough to use in a real casino environment, or to be of any help at all.

Remember, this is just some kid's college project. I'm sure he's enjoying the attention, but this is not an innovation.

The commercial units combine video tracking with RFID for measuring chips and betting. These systems are very expensive, and don't work all that well. They're also easily defeated by skilled card counters using various techniques. This system is too.

As for card counting itself, there is really a lot of misinformation on here, but here's the gist:

- It's totally legal, and it's totally legal for the casino to ask you to leave if they don't want your business.
- They don't do this often, because most people are losers, even if they're trying to count cards.
- They don't care if you win a ton, if you're just lucky.
- It only gives you about a 1-2% advantage overall. That's really not a lot.
- The MIT team didn't invent any of it, including team play. Nor were they all that successful or profitable overall. Disregard the movie, guys.
- It's not that hard to learn, but it does take practice, a strong stomach, and a huge bankroll to ride out the inevitable swings.
- Expected earning is around 1-2 units per hour. So if you're playing $25 units, you'll make $25-$50/hr in the long run.
    Not bad, but not great either. And you should have at least $25,000 (1000 units) as a disposable bankroll to do this, or you risk going broke fairly easily.
- Lots of people think they can do it, but few really can. The ones who think they know what they're doing are subject to lose a lot of money in short order, so the card counting hype is of benefit to the casinos. They've known this since Thorpe's day.
- Casino rules vary wildly from location to location, even with a casino. Same thing for card counting conditions.

Yes, I've studied this quite a lot. Anyone have any questions?
