Slot Machines Systems – Four Players Try To Fake Out the RNG

First of all, let me apologize for the lack of posts recently – family business always takes precedence. While in Florida, I was able to get a few hours away and visit the Seminole Hotel & Casino in Immokolee.

Seminole Casino, Immokalee

Seminole Casino Hotel Immokalee is a Native American Casino in Immokalee, Florida and is open daily 24 hours. The casino’s 75,600 square foot gaming space features 1,300 gaming machines and forty-four table and poker games. The property has four restaurants and a hotel with ninety-nine rooms. It is one of six casinos operated in Florida by the Seminoles.

This post isn’t about that particular casino, but explains that the myths and superstions of slit players are universal.

Mr. Cashman Slot Machine by Aristocrat

On this afternoon, I was mindlessly playing slots.  The man next to me was playing a slot manufactured by the Australian company “Aristocrat.” If you play the top set of buttons on these slots, you can actually play play a tune.  So this man would do this – every time, ad nauseum.  I couldn’t stand it any more and asked him, “why do you do that?”  He said, “I usually get lucky and win when I do – of course it’s not scientific, or anything…”. (No kidding!)

A second young man sat down after he left.  His secret, so he told me, was to stop the reels because he could stop them on winning combinations.  Genius!  Why didn’t I ever think of that?  Oh yeah, I did…….and immediately thought it was rediculous.

After he left, another gentlemen sat at the same machine.  Every time he won’t sizeable amount, he would apply the following ritual: cash out, take his players card out, put cash in (or another Ticket) put his card back in and start playing.  So I asked him, “why do you do that?” He said, “after a big win, the casino compensates for the win by going cold.  So I fake out the machine, clearing its memory of my play.”

One last interesting slot player had a simple strategy – beat the slot machine.  No, not by winning, but by physically beating the machine.  This gentlemen not only tried to “clear the machines memory,” when that didn’t work, he decided go all cage fighter on it striking buttons, screen, etc. mercilessly, I guess to clear its memory by giving it a concussion. For obvious  reasons, I didn’t ask this guy any questions.

The moral of this post is that slot machines don’t have a memory, they don’t breath, they don’t think.  Slot machines are not capable of reacting to the player.  The random number generator  treats every push of the button, or every pull of the lever, as an individual event, not connected to any previous or future event.  Each play is a single event all by itself, and the star of each event us the Random Number Generator.

John Grochowski – the Casino Answer Man

The following day I was reading my gambling alerts and noticed the Casino Answer Man, John Grochowski posted a similar article called “Fooling the RNG.” John sums it up better than I. He says, “You can’t fool the RNG because the RNG doesn’t know how much you’ve bet. All it does is generate random numbers. Different programs then take those numbers and map them onto reels or reel images to show you the outcome. Other programming then takes the result, compares it to your bet size and pays you the appropriate amount……Any outcome can come at any time, and it’s futile trying to time bigger bets for payoff times as in the prime the pump or the step methods. It’s just as futile to try to fool the RNG by betting big early.”

Simply put, understanding the RNG is science, math, and acceptance in what it is – a machine. Betting systems just don’t work on machines.


Three Suggestions to Slot Machine Players

Have you wondered why it seems harder to win at your favorite casino?

We all know that table games are in a state of flux, with lower payouts and more side bets – all increasing the house edge.  We’ve seen blackjack payouts diminished quickly within the last two years with the advent of 6:5 payouts instead of the traditional 3:2.  We’ve seen lower times odds in craps. More “carnival” table games continue to be added to the casino floor like 3 & 4-card poker, Let it Ride, and BlackJack Switch – all table games with high infrequent payouts, volatile side bets, and a much higher increase to the casino’s edge as compared to traditional games like baccarat & blackjack.

Let’s face it, U.S. casinos are making it tougher for players to win at the slot machines as well.  The portion of slot wagers kept by casinos rose to 7.7 percent last year from 7.25 percent in 2007, the Association of Gaming Equipment Manufacturers reported. So, it’s no surprise that the total amount bet on the machines fell to $291 billion from a peak of $355 billion over that span. “Slots have been tightening slowly over time,” Marcus Prater, executive director of the association, said in an interview. “There is a theory out there that when people have a bad experience, they’re not as likely to come back.”


Listen, casino management still doesn’t get it.  The fact is that people will show up if they feel they have a chance, some hope, of playing a while – or even winning.

I understand that the most entertaining slots may be the ones that also don’t pay well.  If you are willing to play them with that understanding, then, go for it. But if you want a better chance to win and a better chance to play longer on video slots, here’s three tips to helping you.

DISCLAIMER: The following information is not going to tell you how to win at slots.  Nobody can tell you that. If someone tells you they are a professional slots player, or that they have a sure way to win at slot machines, RUN – RUN FAR. The Random Number Generator (RNG) is made to pay a certain percentage for the casino’s win over the long term.  No one knows what machine pays what percentage, except the company that sold it and the casino who bought or leased it. So, the following are just suggestions to consider, THAT’S ALL. 

To understand the Random Number Generator, try reading these previous posts:

Understanding The Random Number Generator (RNG)

Big Bang Theory Slot Machine

Suggestion #1 – Be wary of the “Celebrity” or “Themed” slot machines.  These games are referred to as “participation games.”  When a casino installs a participation game, they do not buy the machine.  The machine remains the property of the manufacturer, and the casino and manufacturer share in the revenue that the game produces. However, a fee to license that brand – for example, Ellen DeGeneres, Michael Jackson, Big Bang theory, Batman – which is all figured into the revenue share.  So, because of licensing fees, leasing fees, and revenue share, expect the payout percentage to be lower than a traditional slot.  Just enjoy it for the entertainment it is, and if you win, so much the better.

Suggestion #2 – Know your progressive.  Many slot machines include progressive wins – but not all progressives are alike.  Be knowledgeable of the differences.

  1. “Pay for Play” Progressive – these progressives usually are only eligible for the taking when playing Max Bet.

    A good example is Quick Hit machines.  If you don’t play max on these machines you are not eligible for the progressives, which can get hefty, thus diminishing your total payout percentage – whatever that may be.  The progressive is figured into the total payout percentage.  Play without Max Bet, and you’re throwing away more money to the house.  Always check what denomination and how much Max Bet is before playing.  “Quick Hit machines can range on a penny machine from $1.50 to to $4.00.

  2. “Pay Within” Progressive – these payout on any bet, anytime withing a certain amount accrued.

    For example, Konami slots often have 2-4 different progressives, that will pay between $25 – $50 (a mini progressive) at any given time. Keep in mind that the increase of the progressive is incredibly small. One Las Vegas trip I played a fun slot called Rumble, Rumble “SweetZone” by Ainsworth at Cosmopolitan.  At $1 a play, my wife and I figured out $5 in made the progressive meter increase one cent – $5 increased ONE CENT!  So, be careful – seeing a progressive like this close to its payout could still mean a lot of playing (and money) ahead.

  3. “Mega-Progressive” – these are those that are connected to a few others, or even regionally like MEGABUCKS.

    Keep in mind that to payoff such a large progressive, the payout percentage that you hear sucking the money out of your bankroll will be low.  It has to be to be able to payoff the winner of such a high payoff.  These usually require a high Max Bet.

Suggestion #3 – The less Bells and whistles, the higher the payout.  Again, not necessarily, you don’t really know, you can’t tell, yaddy yadda yadda.  But if the casino doesn’t have to pay other interests such as progressives, themes, lease agreements, additional set up, special lighting, etc, it might encourage your bankroll to last longer.

Sometimes, an old Cashman slot by Aristocrat is just as fun.  My favorite – “Betting Zoo.”

Now, go out there and hit a jackpot.


Slot Machine Problems – A Story to Learn From

Last night I was taking advantage of Mohegan Sun’s 3X Status points offer.  I was playing slots since it gave my bankroll the biggest bang in tier status with a low-roller bankroll.

As I was playing an old Aristocrat Cashman machine seen below (PandaPays),img_1420 I received a Cashman Bonus.  For those of you who still play the original Cashman machines, you will know it as the “slot machine multiplier.”  The multiplier was the rarely seen “999” on max bet.  After over ten playes (remember that, it’s significant!) I wondered if I had been paid correctly.  I stopped, to call for a technician.

After waiting over 15 minutes, I called the Mohegan Sun main number (lesson one if you wait too long) to tell my problem. (Shame Mohegan Sun!) The operator contacted operations and someone was helping me out in 2 minutes.

The technician and the slots manager explained to me that they could check it out.  As they opened up the software, they showed me my last ten plays – time, denomination, win/loss.  But here’s the key lesson.

The slot machine could only show the LAST TEN PLAYS.  I had played more than ten before stopping, thus they couldn’t verify what I was talking about.  As it happened, I was wrong and paid appropriately.slot_machine_tilt_error


On more modern machines, I don’t know if more of the history would be able to be recalled.  And this is not the type of specific information captured on your card.  You wait, you’re screwed.

Hope this helps.
