How do I tell the payout percentage of my machine?

[NewMember0021]

I purchased a used Red White & Blue machine for home use.  I have had 2 out of 3 people hit three 7s and leave winners.  I think perhaps there is a chip in the machine with a payout percentage over 100%.  How do I check this?  I think it has something to do with the eprom chip after a bit of research.  I am looking at the motherboard and the chip that says "GAME PROM" is labeled SP 731, and the chip labeled REEL PROM is labeled S-PLUS REEL \ MECH SS3285 \ 06/19/89 \ @IGT.  I did some research on those labels and could not find anything that related them to payout.  Is there anyway to find out?  Any help would be appreciated.

Well have we got a deal for you.....

If you look on the middle right of the home screen you will see a blue button called called RICKS FAQs

From within that you will see a link in very small type listed as the IGT Game Bible.

You can then choose the number of coins, from which you will see the list of themes, clicking on your theme you will get a description of your Reel Chip and what other ones are available.

The official document that outlines this chip is called a PAR sheet. Paytable and Reel.  if you post back and ask really nicely for a PAR sheet for the chip number  some kind member might email you one from their private collection.

Make sure your profile is up to date with your email address as we don't pass these types of documents through the site.

 I would also discourage you from posting your email address (vs putting it in your profile) as automated web crawlers tend to troll for this kind of informtion in open forum and you may find yourself with a fair bit more spam that you bargened for.

This is a great forum, I found this link http://newlifegames.net/nlg/index.php?topic=156.0 and it gives this series of numbers:

--SS3285 3R 2CM TYPE 0 104B211 94.675

Is this confirmation that the payout of my machine is 94.675%?

3 Reel 2 Coin - Type 0 (meaning no special features) 94.675 is indeed the percentage.

Thank you, can I ask for clarification on a couple of the other stats?  The hit freq is 16.335 and the win freq is 6.12.  I assume the first is % of the time any winning spin occurs and the second is the number of spins expected for a winning spin because 1/6.12 ~ 16.34, correct?  Is the hits/cycle the number of times that the listed prize is given out over the number of possible spins?  The stops listed is 64, does this imply that there are 64^3 given options for the reels?  Thanks.

For this machine, stops is (64)ABC and for the jackpot, hits/cycle is (8).  My guess is that this means the P(jackpot) = 8/(64^3)

OH  Boy.....STATFREAK is going to love having you participate on the site....... your math for the most part looks correct to me.
I am however not so sure about the P(Jackpot) formula... but I am not saying its wrong.

The probabibility of any particular combination occuring = 1/(64^3)
Subsequently P(win) = 0.0612 which is what is given to us

I would then believe Jackpot = 1 / (P(win) x number of winning combinations on the paytable)
                         or                1 / (0.0612 x number of winning combinations on the paytable)


  DAVID ... save me.

You are correct. P= 0.000030517578125. Since most gamblers relate to probabilities expressed as odds of a given occurrence, I usually give the reciprocal of the probability, or 1 in 32,768. This is a typical probability for S+ themes with top prizes paying 800 for one or less.

Technically, it's ~ 0.16334 or ~ 16.34%.    but yes, you are correct. The two numbers are the reciprocal of one another and are redundant. I always wondered why both were used.

Just to clarify, there are 64^3 permutations, however, the outcome selection in a class III game is random and governed by the law of independent trials. Also, the (ABC) refers to the physical symbol order on the strips and has nothing to do with the probabilities. In this case, there are three different strips required for this game.

By the way, welcome to NLG!

David these are the odds for hitting any particular combination and in a truly random scenerio this is bang on.
However the fact that there is a Hit ratio provided by the manufactur does the calculation for PROBABILITY not get altered by the introduction of a constant ?

Well, these are the odds for hitting the jackpot, which is one particular combination. Each winning combination has a specific number of occurrences, and therefore its own probability of occurring. The win frequency/hit frequency in these charts is simply the sum of all winning combinations/total virtual stops^number of reels, or in other words, the probability of hitting anything. According to the PAR, there are 42,820 winning combinations in this game, so P= 42820/64^3 = 0.163345 or 1 in 6.12 pulls.



NewMember0021,
RWB was designed to pay out heavily on mixed sevens; that's why it was so popular and successful a game theme. In this case, there are 880 combinations of mixed sevens. This single payout accounts for a return of 26.86% of the money played. It's not surprising that your friends hit them in the short-term and ended up ahead.

I purchased a used Red White & Blue machine for home use.  I have had 2 out of 3 people hit three 7s and leave winners. ...

That is a distressing comment. I hope that you are not allowing your friends to gamble for real money in your home. That is the fastest way to lose your friends, your machines, and to end up paying fines and doing possible jail time. It's never worth it.   Of course, I'm sure that I just misread your post.
