Shuffling Proms, 'same vs. different' for multi ga

[asteroid]

This past week's Gambling With an Edge talked about a scenario in which a vp machine was unplugged. A patron wanted to play the unplugged machine and asked a slot person if it could be plugged in and played. The slot person plugged it in and the person started hitting big hands (quads with kickers IIRC) over and over again and amassing a large number of payout tickets. The casino manager said there was a problem with the machine and I think told the person they need to return the tickets since the machine was "defective". The machine was turned off again and placed out of order. Why would this need to be done if the RNG is totally random ? I think the casino manager specifically said the reason was because the wrong chip was in the machine. Someone who also listened to this podcast may have further details.hello All;

I'm interested in knowledgable replies and comments to the following statements/questions. I am a long-time VP player; played literally millions of hands in the past 25 years. I have logged my play by machine number and denomination for the past 5+years. Below, I am strictly discussing Las Vegas Area VP.



Below are some statements of fact, and some questions. They may best be commented on by a machine collector of SW engineer, but I'm hoping for informed comments, rather than guesses.

Fact: Every modern VP machine has a chip (or more than one???) with some sort of shuffling algorithm.

Fact: On some multi-game machines (only older ones??) When a hand is over, if you change games or denominations, the last hand you just played REMAINS THE SAME on the screen no matter which game you choose. On some machines (newer??) it changes to the last hand played at that specific denomination and game.

I'm interested in verification of the two places above where I have placed question marks.

I know that Nevada gaming must APPROVE the various shuffling algorithms that are in play in each game.

Questions: (And let's stick with a 52 card deck for this )
WHY would there need to be VARIOUS shuffling algorithms (PROMs) to be approved? In fact, WHY doesn't the STATE OF NEVADA issue the randomizing dealing chip to ENSURE fairness?


I encourage intelligent comments, answers, and ideas.

I am convinced some machines behave differently from others.   If anyone cares to say they are all the same, I will be happy to fly to Las Vegas, and have a significant wager with you. The wager would be that I point you to a machine, and you play 1000 hands of game X, and I play 1000 hands of the identical game at a machine of my choice.   I realize 1000 hands is not significant, so, in theory if repeated several times, we should end up each winning this challenge roughly equally, correct? I will bet that we do not.

Please accept I am not taking shots at anyone here; I am merely saying I can point out machines that seem to CONSISTENTLY have LONG quad and 'high-payout' cycles compared to other machines (note the word CONSISTENTLY) or that have long gaps or no flush/boat/straight payouts that will KILL you in the short run. I want to know WHY there are various shuffling algorithms, when exactly ONE should do.

Thanks!

When machines are being shown at gaming expos, they have different software to show off many winning hands. Maybe that machine had the demo software?

Perhaps. Unfortunately, no further details were given during the podcast in regards to the specific issue with the chip. I hit a wild royal (OEJ) the other day on an IGT slant top (cashing out immediately and leaving the casino) with a two card hold and when I came back the next day, the game was off with a laminated "out of service"  sign resting against the screen (now it's back in service again). It is probably nothing of course, but when considered in aggregate with the story on GWAE and story after story from 30 year veteran vp players, I don't necessarily think it should be totally dismissed. When machines are being shown at gaming expos, they have different software to show off many winning hands. Maybe that machine had the demo software?
