Do The Casinos Cheat At Video Games Part3
Dr. Schneider: Cheating then would have to concern the actual randomness of the shuffle. That would be the first place to look. Perhaps the machine has been programmed to never allow a royal flush. Or, only allow the royal flush half or three quarters of the time. If I take the three-quarter example, when the cards are dealt out, any time a king of hearts comes up, the ace of hearts is behind it. Thus there can never be a hearts royal flush. Let us assume that machine deals out 10 cards, the first five of which are visible…
Frank: Parallel dealing.
Dr. Schneider: Parallel dealing. The other cards are behind these first five. So behind the king of hearts would be the ace of hearts—at all times. You would never know this because when you had three or four cards to a royal flush in hearts, you wouldn't discard the king of hearts so you wouldn't ever see the ace of hearts. Or, if a player made a mistake and did discard it, it would be a curiosity that the ace was behind it. What I've just described wouldn't even be a subtle programming technique. You could program a color in its place. Four to a royal in hearts are red, the discard goes and you receive a black card—you might even get a high straight. The programming could even specify that a normal flush appear. So, you program the machine this way. You have a sequence of 10, jack, queen, and king of hearts. The fifth card is the six of diamonds. Behind it is sitting the ace of hearts. When you discard the six, that ace will show and you have yourself a royal flush. Now, the machine senses the ace and simply substitutes a four of hearts. The player gets a flush but doesn't get the royal. The player would never suspect a thing. The player would be happy he received the flush, a little disappointed that he didn't get the royal and the casino has successfully cheated the player.
[Here I explained to Dr. Schneider my concern that machines I had played in Las Vegas might be substituting like cards for discards in four-to-a-straight hands.]
Dr. Schneider: Such a situation could be happening. However, I doubt that a programmer for one of these companies, even if he were told to cheat the customer, would do so in such an obvious and unsubtle way. After all, you picked this up quickly and anyone who played for a decent length of time would pick this up also. The four-to-a-straight hand occurs frequently enough that a like-card replacing a discard would certainly be noticeable—especially if it were 20 percent of the time or more as you indicated. If it is happening, there could be a problem with the random number generator's programming. It would be a programming flaw, not an attempt to cheat.
