Confronted with a slot machine, the system responds in the way that has contributed to the success of the organism’s ancestors. Of course the response is not optimal given current conditions, since it fails to learn that there is no regular relationship between any one play of the machine and another. In other words, a single episode of slot-machine play engages well-characterised reinforcement-learning mechanisms mediated by mesolimbic dopamine pathway,13, 14in order to shift reinforcement signalling from game outcomes to their preceding anticipatory states.

Main Digest
Please note that the article below is my opinion only, from what I have experienced from playing slots, both at land based casinos, and several different popular online casinos - all of which shall remain nameless.
Playing slots, pokies, fruit machines, one arm-bandits, poker machines, whatever you like to call them, depending on where you come from, is a popular pastime for many seniors and retired singles and couples.
Are Slots Really Random?
What Casinos and Slot Machine Technicians Will Tell You:
Online casino slot games are said to use the same kinds of random number generator programs as land-based casinos. They just serve up your results via animation that is sent to your computer via the Internet.
Casinos will often tell you that slot machines use a computer to generate random numbers, and these determine the outcomes of the game. When players press the 'Play' button, the machines computer generates what is known as a RNG, a gaming term that is an abbreviation for 'random number generator'. Random number generators (or pseudorandom number generators) are special algorithms that are used in computing when an outcome needs to be as random as possible.
- When the play button is pressed the RNG randomly selects a winning or losing combination from among millions of available combinations.
- Slots don't get hot or cold - Slot machines are said to have something in common with goldfish: they have no memory. Every spin is independent of the prior and/or following spins.
- Every spin is considered to be a brand new spin, with any possible symbol combination outcome.
- Slot players are said to either win or lose; they never 'maybe win' or 'maybe lose', or never 'almost win'.
Slot machines often display a series of spins where players appear to be only one symbol away from a win, therefore leading them to falsely believe that they almost won. Slot games do not work on any kind of cyclical basis - and slot machine jackpots don't become due.
I call BS!
Why I Believe Slot Machine Games are Not Random
Slots are not random and I will never be convinced otherwise, I have been playing slots for many years and seen so many different examples of them being NOT random, making it incredibly difficult to believe that slot machines are totally random, here's why:
- If slot machine games are designed to fit into a maths model, which they are said to be, then they cannot be TRULY unpredictable.
- I have played certain online slot machines where the 'Payout' or money won amount is displayed BEFORE the bonus game spins end.
- How is it possible for a slot machine to be a random device and for a machine to also have to pay back a certain percentage of the money played through it?
- Anyone who's played certain slot machines for example, could not fail to notice how you don't see ANY certain symbols on the reels for ages, then suddenly they are everywhere!
- It often feels almost as if there is some algorithm at play preventing a certain feature to happen too soon after starting a slot game, and only happening once you've lost enough money to cover the feature's payout.
- Have you ever been steadily winning playing a certain amount, e.g $1, so you decide to bet more to win more and increase your bet per spin to $2. What happens? The machine 'instantly' stops paying and becomes deader than a Dodo bird! Strange isn't it, considering slots are supposed to be so called 'random' (sarcasm).
Screenshot of the Mad Mad Monkey online slot game.
On some progressive jackpots linked to a bank of slot machines, the jackpot has to be won before a certain amount of money is reached. Now, if this is the case, how are they REALLY random if they have to hit before the jackpot reaches a certain amount? Totally random means they can hit at ANY time. If they have to hit by a certain amount they have to be programed to do that.
I was once asked in an 'anonymous' online casino survey, 'If I felt like I received enough playing time for the amount of money fed to the slot machine!' Now, why ask something like that if it is beyond their control to 'adjust the settings'? Was it because if a player was losing their money too quickly - resulting in a shorter machine play time - then the machine would 'compensate' by paying out more before the end of the playing time? This time of play adjustment would then allow casino patrons, both on and offline, to 'feel' they had value for money due to the adjusted extension of playing time on the machine.
Losing on One Machine - You'll be Losing on All Machines!
What I don't get, if you have a win on one particular slot game and then move onto several others, they will all be dead. For every win I have had I then lose constantly until the money I won and some has been played back, no matter what slot I play before I even begin to get above my deposit back again - it is the same pattern each time and that does not appear random to me. It's as if all the online slot machines are linked to a central computer - For example: If you are continually losing, when playing online slots, switching to another slot game doesn't matter as all the games you try do not payout as well. The only so called random thing is if your players account has been deemed worthy of a win for a change. It would be extremely easy, and fast being a computer, for a 'central computer' to check the deposits, as well as wins and losses, your account has had over a certain amount of time and money deposited. Your account is then compensated for the losses with smaller, or medium amount, wins that will always see you losing over the long term.
Have You Noticed
Have you ever noticed that you miss out on a good winning combination because just one reel wasn't in the right position? Then lo-and-behold on the very next spin the symbol you needed is right where you needed it to be on the previous spin! Random? Nah! Teaser? Yes!
When in a bonus game and, for example, you have to select 3 symbols from a group of symbols in order to reveal the bonus money, number of free spins, or number of free spins and the winning combination multplier factor, 'beneath' the symbols. Once you have made your choices and the selections are revealed all the other symbols may be revealed as well - often with a better option than the ones you picked. Rest assured that had you picked the 'better options' you would still have made the EXACT SAME choices - So it's no use saying, 'If only I had picked that symbol...' As you don't know what's 'under' any symbol at the start of the bonus pick, the computer can, and does, calculate the amount of free spins etc. it is going to give you, and then reveals whatever it wants to 'under' those symbols you both did and didn't choose. Nothing is actually ever 'under' those symbols to pick from, the machine simply changes the icon picture to whatever its current calculation amount tells it to reward you.
Have you also noticed that after a modest win, or payout, assuming you keep playing the same slot machine, it almost seems as though the game NEEDS to win that payout back before giving you another, abeit smaller payout.
Have you ever been playing the slot machines, at for example $1 a spin, and you get a reasonable size payout win and wish you had bet $5 like you were a few minutes ago? Well rest assured had you been betting $5 a spin the win would not have been 5 times as much as your $1 spin - the machine would not have been 'ready' to payout that amount at that time.
In my experience it seems quite obvious that slot machines have to have some sort of computer coded system at play to ensure you can't win over and over again - Which is why when you do win big it is always followed by a long cold losing streak.
When bonus round occurs it ALWAYS seems the bonus round happens 2 or 3 more times in a short period after the first bonus round, then no bonuses for ages - and lots of cash gone.
Also in my experience, any big wins I've had in the past have come when I've spent a small fortune on that particular slot - almost as if the slot is forced to bring you back in line with the payout figure percentage rules.
Left to right paying slot machines are designed so high paying symbols are frequently on the 1st reel, slightly less frequent on the 2nd reel, less again on the 3rd reel, less yet on the 4th reel, and very rarely on the last reel. It is another trick by slot manufacturer's to gives you the feeling of possibly winning and missing out on the last couple of reels.
The online casino wants to keep you as a player - when playing you may seldom get any wins - then when you are near your last money in the machine you receive a moderate win - just enough to make you come back to that casino for more.
I've played them long enough to believe that they're not random, but as I said, it's my opinion from my personal observations, and you're entitled to yours. Next time you are playing slots stop and wonder why those top slot symbols and/or scatters mysteriously vanish after a while - short-term random, sure - long-term random, not so much...
Feedback on This Article
1 - A Mathematician Agrees
Recently Disabled World received an email from Dave M. stating his opinion. With his permission we have added the content of his email below:
Hi, I have just been reading an article by Jungle Jim on slot machines that was posted on your site, which was very illuminating, and everything he says seems to be quite accurate. Although the article is from a few years ago I found the contents gave quite a representative appraisal on online slot machines and land based slot machines.
My own area of interest however is the online slot machines.
Over the past few months I have been conducting my own research being a mathematician I was interested to find out if these forms of gambling were in actual fact random number generated as the major casino's , bingo halls and other gambling establishments claim them to be.
Firstly I played an online popular slot machine after joining a popular bingo hall and online company. And low and behold after depositing a modest sum had a virtually immediate win followed by subsequent wins giving me a substantial reward on my investment.
Then as if a button had been pressed to say OK this person has won enough and is now 'hooked' when trying other slot games those wins accrued from a previous slot game was starting to be eroded away quite rapidly with a succession of totally win free blank spells apart from very low denomination pay outs.
So before the 'winning pot' had been exhausted I returned back to the original slot game to try again after a day or two. And low and behold it subsequently eroded the rest of the winnings paying absolutely nothing in the way of substantial wins, only small denominations until it was all gone, this in my opinion is a very systematically heavily controlled form of gambling which also in my opinion is not random at all.
I went on for the next several weeks to play and document all the wins and losses from some free game plays to see if there was any difference between them and the paying games and over a period of time playing the free games found that these games always paid substantial wins consistently.
However in between when switching back to the paying money slot games it was always whittling whatever I deposited away, without any substantial wins whatsoever. This I documented and found over a period of time that the wins I initially procured was taken back three fold.
So my research has concluded and justifiably concurred with Jungle Jim's opinions that online slot machines are not random number generators at all and are in my opinion being governed by the operators and companies that are running them.
2 - RNG is NOT RNG
It seems there are many many people out there who agree completely with the article above. Here is one such email, (permission was obtained to include it on this page), from Lewis T. who wrote in under the heading 'RNG is NOT RNG...'
Hi, I'm a fellow slot machine player at a few of my neighboring casinos and way before I came across your post, I noticed those patterns and it wasn't just with slot machines but also with Roulette when I saw the momentum of the ball slow down, rest in one spot, then started vibrating extremely, then rolled around the metal ring and land in another pocket. From that point on I stayed away from roulette and would always watch closely as to how the ball would do the things it would do - yet no one would notice it but me!
As for the slot machines, I would take videos of how the reels would go into hyper-speed all to avoid the bonus symbol it would, and or should, have landed on. All the casino games are suppose to be regulated but who can you really trust them when money runs the world and the gaming commission is getting their pockets loaded by the casinos that are suppose to be operating fair games.
These places have a operations room that allows them to control the winnings and the losings, from the games all the way to the rewards cards they persuade you to sign up for, all for them to regulate you even further.
It has been too many times that I've sat down, inserted my rewards card, inserted my hard earned money and played until I exhausted my $100 in the machine. Then I would sit and watch someone sit right down behind me and play the same game and hit so many bonuses RIGHT AFTER I FINISHED PLAYING! And it wouldn't be just one instance.
The way my mind works I can focus on the whole game verses just focusing on one reel and see the rhythm on wins and loses, and this is just from me!
How are these establishments, the gaming commission, and all the other 'gaming regulators' able to get away with preying on people and get away with it???
3 - Slot Games are Not Random at All
John V. wrote into Disabled World to give his opinion on the unfairness of slot payouts:
The opinions of Jungle Jim to me are what I have been saying all along as well. The games are not random at all, to me the one thing I notice most is 100% of the time you get free spins or a bonus on one game, win some money, then guaranteed after if you keep playing that game you will not get another free spin or bonuses for a long period of time.
What I do is if I get free spins or a bonus I will spin maybe couple times after knowing I will get nothing, then I will change games right away. You have to be very focused when playing and be very patient. When you have low balance bet small as you have to slowly build up your balance, then when you get to around 200 I would say you can start playing the jackpot games, bet more per spin on regular slots etc.
They are definitely not random they try to brainwash you and tell you they are, but when you're an experienced player like myself you play a game for a while give it a chance don't go in thinking I will play till I get free spins or a bonus you could lose a lot of money thinking that. Just play 20 spins or so if theres nothing then move on don't get lazy and stick with the one game, be focused take your time if you feel like your getting very frustrated and angry turn the casino off take break if you don't you will lose it all with in minutes.
It's a game between you and the casino. You can win once in a while, but don't go in expecting to win and wonder why a game paid out so well yesterday and today there is nothing at all. Emotions are key, be relaxed, be alert, and take your time be smart, and you have a good Chance in winning. I have done it 7 times. I have withdrawn money in the last few months that's pretty good so it can be done. Good luck to you all.
Let's Keep the Discussion Going!
So, are slots really random? What do you think? Can you add to the above lists on how you think slot machines may be cheating? If so contact us, as we'd be interested in more opinions.

Social media has changed our lives irreversibly. The innocence of sharing photos with family and friends; announcing some of life’s biggest moments; publicising local events; publicising absolutely anything … social media has become one of the primary ways we communicate as a modern society.
As of 2019, the number of internet users worldwide is 4.38 billion, and the number of those internet users engaging on social media is 3.484 billion, up 9% year-on-year. Another industry booming, the engagement seen in the world of gambling has risen to a mammoth $25.69 billion—partially down to growth in online gambling, and particularly the rise of virtual one-armed bandits; from online slot games UK all the way to the pokies of Australia.
One may struggle to see the connection between social media’s spiralling omnipresence and a practice that dates back to the Paleolithic period, before written history began, but social media has recently faced criticism for its addictive qualities and parallels with slots. Many users, including some of Silicon Valley’s biggest tech players, have decided to curb their time on social media, even going so far as to install apps to control their usage. Those not as switched on, however, are facing increasing addiction to their devices.
Justin Rosenstein—co-founder of software company Asana and former employee of both Google and Facebook—is part of a growing number of individuals speaking out on the addictive nature of social media and the way it has the potential to limit our productivity. Rosenstein is an expert in the field—he was after all the Facebook engineer who created the same ‘like’ button that he now avoids pressing.
“Everyone is distracted,” says Rosenstein. “All of the time. One reason I think it is particularly important for us to talk about this now is that we may be the last generation that can remember life before.”
The advent of the ‘pull to refresh’.
One of the Silicon Valley heavyweights joining Rosenstein in his critique of social media is Tristan Harris. Formerly a design ethicist at Google, Harris is the director and co-founder of the Center for Humane Technology as well as the cofounder of the Time Well Spent movement. He’s coined the phrase ‘human downgrading’; a term that suggests that computers are actually transforming people’s lives for the worse. In 2016, he was described by The Atlantic as “the closest thing Silicon Valley has to a conscience.”
Harris believes that the design of social media applications apply some of the same principles that can make other forms of entertainment, like gambling, exceedingly alluring. He has previously called smartphones the ‘slot machine in your pocket’ and is campaigning for stronger ethics in Silicon Valley, as well as the tech industry more generally.
“Each time you’re swiping down, it’s like a slot machine,” he says. “You don’t know what’s coming next. Sometimes it’s a beautiful photo. Sometimes it’s just an ad.” What slot machines and social media share are variable rewards.
This feeds into the ‘pull to refresh’ function. Every time we pull down to refresh our timeline—whether that’s on Facebook, Twitter or even by email—we don’t know what we’ll discover. That could be a new email from work, lots of surprising ‘likes’ or even disappointment should there be nothing fresh to excite us. The downward-pull action, created by designer Loren Brichter, has been emulated across many different apps, and its ubiquity has become intuitive for its users. Being drawn into what’s called ‘ludic loops’—where a user is unsure whether they’ll receive feedback (or in the case of a slot machine, cash rewards) following anticipation—is what keeps us hooked. Or, as Harris says: pulling the lever.
“You pull a lever and immediately receive either an enticing reward (a match, a prize) or nothing,” says the Silicon Valley activist.
Quick reward psychology is nothing new. American psychologist B. F. Skinner at Harvard University was a pioneer of the concept. His theory of Operant Conditioning, which he first made reference to in 1938, is a method of learning that occurs through punishments and rewards for behaviour. What it comes down to is our conditioned associations between a particular behaviour, like pulling a lever on a slot machine, and its consequence: winning rewards. It’s what makes entertainment like gambling, and new forms of technology, like social media, so alluring; activities we want to come back to, again and again.
All fun and games?
The most simple way of explaining the deep psychology behind users of slot machines, especially online slot games, is that they’re fun to play. The success of the industry speaks for itself. The UK Gambling Commission report shows a massive 12.8% increase in the online gambling sector, accounting for £5.3 billion in Gross Gambling Yield (GGY) during the year. During 2016, online slot machine style games alone generated £1.8 billion in the UK. It’s one of the largest revenue generators of the sector and continues to grow year-on-year.
That the industry has become so lucrative has had many benefits for the players who enjoy online slots. The more income generated by the slots, the more people want to get a part of the action. Including game developers, publishers and brands. The saturation of the market has resulted in many advancements in game technology. Newer, more exciting games are being published every week as game companies compete in the marketplace. And with developments like augmented reality (AR) and virtual reality (VR), online slots are continuously evolving as they become more and more entertaining for the people who access and enjoy them.
The success of the industry—and the fun it elicits for its many players around the world—makes it a fine example for other sectors to try and replicate. That many of the techniques used to entice people to play online slots are being used by social media companies makes sense: they know a good model when they see it.
Where casinos have used techniques like air filtration and a lack of natural light to keep their gamblers in a limbo-like state, online gambling has allowed users to dip in and out of gaming anywhere, at any time of the day, and social media shares this perma-connection. Smartphones guide us out of any situation we don’t want to be in, it negates awkward silences, deletes boredom at the source. We are bombarded with stimuli and all of the techniques learnt from the world of gambling keep us coming back for more.
Of course to be ‘an addict’ requires a predilection to addiction, it requires pain that cannot be coped with another way, not everyone will become addicted. But this doesn’t mean that Silicon Valley shouldn’t look at the techniques it employs. “The ultimate freedom is a free mind,” says Tristan Harris, “and we need technology that’s on our team to help us live, feel, think and act freely. We need our smartphones, notifications screens and web browsers to be exoskeletons for our minds and interpersonal relationships that put our values, not our impulses, first. People’s time is valuable. And we should protect it with the same rigour as privacy and other digital rights.”
Just think next time you ‘pull the lever’: do you really need those likes?
