THE RANDON NUMBER GENERATOR

[stayouttadabunker]

lol I'm sorry Rocket...you know how we go off track.

What are the differences in RNGs between let's say an S+ and a Bally 5500?
Is this number generator contained in the chip software or microprocessor component on the MPU's?

Bunker,
What's the deal with the Seminole Indians?
I think they partnered with Hard-Rock to get started because they had no idea how to run a casino. Then bought out the Hard-Rock to take sole possession, but kept the name. ??

lol...I'm in new york...I have no idea what's going on down in Florida.
I thought they were still counting chads on voter ballots.

there will be new information I uncovered 

In the past month I was away --of the so called RNG 

once I get all the info together off 3 computers & one hand written note book .I will post
the method that these artices say abut the RNG -- 100% better reading than the novel  I posted before.

it actually makes  some common sense this time -which makes you wonder before --how correct I was on
a RAM CLEAR --THAT MACHINES HIT MORE FREQUENT .. which heated debates arrived afterwords .


heated debates on NLG's NEVER !!

Ok, back to the RNG. Where is this info you promised after resurrecting this thread on July 21st???

Hey Bunker,
      No problem and thanks for the information......It's nice to hear from someone who knows and not someone who was paid to say things.....LOL
Anyway sounds like typical Big goverment trying once again to screw the little guys. In which case the Indians have always gotten the short end of the stick from the white goverment. I do feel for them.

So to get back on track I going ask what I think is a simple question. Does RNG in Video Poker have only 52 numbers one for each card or 2,598,960 numbers one for each possible five card poker hand or something different?

Rocket, Sorry about your Knee. Hope everything turns out well in the end.

Its my understanding that for each deck of cards in a Video Poker, Blackjack game etc that the computer selects 52 random numbers and creates a virtual deck.

Cards are then dealt from the stack - ie you get your 5 basic cards, subsequently when you hold 2 cards, and 3 new ones are dealt they are pulled from the virtual stack.

Now with respect to the double up feature - I am unclear if the cards are shuffled (randomized) before each pass but assume 5 cards are dealt for each double up choice it would take less
than 10 successful passes for all the cards to be used up..... but.... I am pretty sure this situation is handled.

[uniman]

I seem to recall from old posts on the old site that the IGT pokers have their RNG whirling threw the 52 cards until the spin/max bet button is pushed. Then 5 cards are selected. When cards are discarded, the RNG is again whriling through the remaining 47 cards and produces the drawn card(s).

The Ballys as I recall have their RNG whirling through the 52 cards and draw 10 cards, five shown and five in a stack to replace any discards.

Doesn't make any difference, just like a real draw either way.

Now, I could be wrong here, but this is what I remembered.
Anybody else remember this??

[Neonkiss]

have their RNG whirling threw the 52 cards

I have always wanted to know the speed of the selection of the RNG.
You say whirling, but is it possible that the RNG actually runs really slow?(changing once every second)  It would just take it forever to complete one cycle and if the machine is idle it could pass the top award.

Does anyone REALLY know?   The odds would be the same.

Hi All

Here is an good article I found while researching I Gaming - http://www.igamingbusiness.com/sites/default/files/file/March_%20April%202009/28-29_Mar_Apr09.pdf.

Neonkiss - My guess is that it would run pretty fast. The only way you really would know is to decompile the SW. Probably every platform/model would handle this diferently. Maybe somebody like Stolistic that get these things running in mame could shed some light ?

Rocket - Hope the Knee Op goes well.

My bulb is burned out...

[uniman]

don't kill the messenger --this is a quick answer to  post above .
now what i say so no fights start is my words!!  I dont claim its the truth ---its readings of books manuals etc

IF MACHINE IS RAM CLEARED OFTEN
THEN THE PAYOUT PERCENTAGE WILL NOT HOLD TRUE TO THE REEL CHIP % -
important read below

reason being is the cycle of numbers that has cycled and stored has been erased --then has to start all over again after a ram clear --this will explain why a ram clear will produce more frequent wins after its been done -

because the cycle of numbers has not grown enough>>> to follow the long term payout pattern<<< that we all have been told the %percentage of a machine is based on the life of machine not two weeks of play   ---thats why new machines in a casino may appear to be hot payouts while first installed because the RNG has not been cycled enough to fill the main board and mother board with 1/2 million pulls !!


now I am not going into the mathematical method that is used to calculate the percentage of payout at this time
because it is not in front of me --plus there are conflicting mathematical methods used I have found .


this alone will make the light bulb light up in many minds after reading this alone .

I disagree with the above statement and/or assumption.
But the rest of the post with the 100 spin pause, CMOS storage, etc is good stuff, thanks Rocket.

The reason I disagree is that the S+ usually had about 66 virtual stops per reel. Maybe up to 256 stops per reel.
So at most the RNG is producing up to 256 different numbers or remainders of numbers. This 256 number cycle would be completed in a second or less and then over and over. The chance of hitting the jackpot symbol would be relatively the same from the second it is turned on for the first time until the day it is retired. Now I said cycle but it is a random event so several numbers could come up more than others during any one period. The number retrieved from the RNG is added to the beginning of the virtual stop table and whatever symbol is at that location in the table is where the reel stops. Different games have the jackpot symbols at different locations on the reel and in the virtual stop table. So no one number is "The golden number". Depends on the game.
Interesting reading, thanks again.

RNG ..

R - REALLY hard to figure out if you are going to win and chances are you are not going to.
N - NOT likey to win anything big and most likely you will give back what you did win.
G - GOOD thing your bank roll is small .. see N.

That is all you need to know about RNG.
