The gaming industry is big business in the U.S., contributing an estimated US$240 billion to the economy each year, while generating $38 billion in tax revenues and supporting 17 million jobs.
How slot machines work – and why you should think twice before playing them The price of a slot. An important economic theory holds that when the price of something goes up, demand for it tends to. This difference in price perspective is rooted in the gap between the. Slot machines include one or more currency detectors that validate the form of payment, whether coin, cash, voucher, or token. The machine pays out according to the pattern of symbols displayed when the reels stop 'spinning'. Slot machines are the most popular gambling method in casinos and constitute about 70% of the average U.S. Casino's income.
- As explained in our How Slots Work article, every spin of a slot machine is a random, independent event. Slots have no memory of past wins when determining the result of the next spin. Win or lose cycles aren’t programmed into slot machines. How Can a Slot Feel “Hot” or “Cold” if Every Spin is Actually Random? Because random data can still have trends. If you flip a coin 1,000 times and record the results, you’ll likely find groupings of several heads or tails in a row.
- Casino slot machines typically have the highest payouts at 95%. This means that for every dollar you put in, the machine is programmed to give back 95% of it at some point. Other gambling locations such as airports, bars, grocery stores, and service stations typically stock machines that have a 50% to 75% payout.
- When the High Limit Slot Lounge opened, Cosmopolitan touted a new system for “processing jackpots right at the machine.” As most slot players know, winning a jackpot of more than $1,200 in a Las Vegas casino means filling out tax forms so The Man can get his cut of your hard-won windfall. It’s annoying, but it could be worse.
What people may not realize is that slot machines, video poker machines and other electronic gaming devices make up the bulk of all that economic activity. At casinos in Iowa and South Dakota, for example, such devices have contributed up to 89 percent of annual gaming revenue.
Spinning-reel slots in particular are profit juggernauts for most casinos, outperforming table games like blackjack, video poker machines and other forms of gambling.
What about slot machines makes them such reliable money makers? In part, it has something to do with casinos’ ability to hide their true price from even the savviest of gamblers.
The price of a slot
An important economic theory holds that when the price of something goes up, demand for it tends to fall.
But that depends on price transparency, which exists for most of the day-to-day purchases we make. That is, other than visits to the doctor’s office and possibly the auto mechanic, we know the price of most products and services before we decide to pay for them.
Slots may be even worse than the doctor’s office, in that most of us will never know the true price of our wagers. Which means the law of supply and demand breaks down.
Casino operators usually think of price in terms of what is known as the average or expected house advantage on each bet placed by players. Basically, it’s the long-term edge that is built into the game. For an individual player, his or her limited interaction with the game will result in a “price” that looks a lot different.
For example, consider a game with a 10 percent house advantage – which is fairly typical. This means that over the long run, the game will return 10 percent of all wagers it accepts to the casino that owns it. So if it accepts $1 million in wagers over 2 million spins, it would be expected to pay out $900,000, resulting in a casino gain of $100,000. Thus from the management’s perspective, the “price” it charges is the 10 percent it expects to collect from gamblers over time.
Individual players, however, will likely define price as the cost of the spin. For example, if a player bets $1, spins the reels and receives no payout, that’ll be the price – not 10 cents.
So who is correct? Both, in a way. While the game has certainly collected $1 from the player, management knows that eventually 90 cents of that will be dispensed to other players.
A player could never know this, however, given he will only be playing for an hour or two, during which he may hope a large payout will make up for his many losses and then some. And at this rate of play it could take years of playing a single slot machine for the casino’s long-term advantage to become evident.
Short-term vs. long-term
This difference in price perspective is rooted in the gap between the short-term view of the players and the long-term view of management. This is one of the lessons I’ve learned in my more than three decades in the gambling industry analyzing the performance of casino games and as a researcher studying them.
Let’s consider George, who just got his paycheck and heads to the casino with $80 to spend over an hour on a Tuesday night. There are basically three outcomes: He loses everything, hits a considerable jackpot and wins big, or makes or loses a little but manages to walk away before the odds turn decidedly against him.
Of course, the first outcome is far more common than the other two – it has to be for the casino to maintain its house advantage. The funds to pay big jackpots come from frequent losers (who get wiped out). Without all these losers, there can be no big winners – which is why so many people play in the first place.
Specifically, the sum of all the individual losses is used to fund the big jackpots. Therefore, to provide enticing jackpots, many players must lose all of their Tuesday night bankroll.
What is less obvious to many is that the long-term experience rarely occurs at the player level. That is, players rarely lose their $80 in a uniform manner (that is, a rate of 10 percent per spin). If this were the typical slot experience, it would be predictably disappointing. But it would make it very easy for a player to identify the price he’s paying.
Raising the price
Ultimately, the casino is selling excitement, which is comprised of hope and variance. Even though a slot may have a modest house advantage from management’s perspective, such as 4 percent, it can and often does win all of George’s Tuesday night bankroll in short order.
This is primarily due to the variance in the slot machine’s pay table – which lists all the winning symbol combinations and the number of credits awarded for each one. While the pay table is visible to the player, the probability of producing each winning symbol combination remains hidden. Of course, these probabilities are a critical determinant of the house advantage – that is, the long-term price of the wager.
This rare ability to hide the price of a good or service offers an opportunity for casino management to raise the price without notifying the players – if they can get away with it.
Casino managers are under tremendous pressure to maximize their all-important slot revenue, but they do not want to kill the golden goose by raising the “price” too much. If players are able to detect these concealed price increases simply by playing the games, then they may choose to play at another casino.
How Do Slot Machines Really Work On Tv
This terrifies casino operators, as it is difficult and expensive to recover from perceptions of a high-priced slot product.
Getting away with it
Consequently, many operators resist increasing the house advantages of their slot machines, believing that players can detect these price shocks.
Our new research, however, has found that increases in the casino advantage have produced significant gains in revenue with no signs of detection even by savvy players. In multiple comparisons of two otherwise identical reel games, the high-priced games produced significantly greater revenue for the casino. These findings were confirmed in a second study.
Further analysis revealed no evidence of play migration from the high-priced games, despite the fact their low-priced counterparts were located a mere 3 feet away.
Importantly, these results occurred in spite of the egregious economic disincentive to play the high-priced games. That is, the visible pay tables were identical on both the high- and low-priced games, within each of the two-game pairings. The only difference was the concealed probabilities of each payout.
Armed with this knowledge, management may be more willing to increase prices. And for price-sensitive gamblers, reel slot machines may become something to avoid.
Casinos have more slot machines than all of the other games combined. But unlike many casino games, the slots still have some secrets.

Here’s a list of 15 slot machine secrets the casinos don’t want you to know about.
1. Slot placement isn’t random
Although casinos would like you to think that everything on the floor is placed in a completely random way for ease of access and aesthetics, this certainly isn’t the case.
Every square foot of the casino is analyzed, measured, and reported on by the casino gaming department. Traffic patterns are monitored and value is placed on certain areas of the casino to determine which slots or games to place in that area.
Usually, the highest yield slots are placed in the most popular locations in the casino. On top of this, the most popular slots are also placed in these areas to attract players into the casino to play.
So now you know that those slots that are most prominent and visible are the ones that make the most money for the casino, which means they’re also the most disadvantageous for the player. Head towards the back of the casino next time you want to play slot machines to find a better value.
2. Some slots pay out more than others
Not all slot machines are created equal, and this means they all don’t pay out at the same rate.
Generally speaking, video slots pay out less than classic reel slots. This is because reel slots are cheaper to run and maintain, and aren’t as appealing to the player as the video slot.
Video slots are now extravagant and have pop-culture themes, which attracts more players. Because of this, the casinos can dial down the payout rate.
Alternatively, the classic slots aren’t as popular or appealing anymore so the casinos will dial up the payout rate to attract more players, and subsequently keep you at the slot longer. I suggest you do a bit of searching on the internet about slot payout rates as this information is widely available, particularly for popular gaming locations.
3. The slots club doesn’t exist to reward you
This is one of the biggest cons in the gambling industry. You know how the casinos promote themselves as giving back to the player and rewarding you for your play? This is all a lie.
Now, I’m not saying you won’t get some free play credits, access to promotions, and other comps for being a part of the slot or player’s club, but this isn’t why it exists. It exists to provide the casino marketing department with player data so that they can attract and retain you as a customer.
Yes, that’s right, all the free money and comps you get out of the casino are from the marketing department. They will analyze your play, movement, likes, dislikes, and betting patterns to determine how best to market themselves to you so that you return.
The slots club is a powerful marketing tool, and while it’s always a good idea to join and use your card whenever you play, don’t fool yourself into thinking that this is all done to reward you.
4. You can’t win at slots in the long run
People do win at slots all the time. They have big wins and small wins; the problem is that on a long enough timeline it’s impossible to win.
Slots are manufactured and programmed in a way to ensure that they only pay back a certain percentage of the money that’s placed into them by players. Usually, this is in the range of 70-90% but it can be far worse or better depending on where you’re playing.
No one would ever play if you didn’t win from time to time, so this is also built into the machines. Some casinos don’t want you to know this and in some US states, they don’t even have to tell you what the payout rate is. Fortunately, there are many states that do provide it to players, and I highly recommend taking advantage of that information.
Although it’s pretty common these days for players to know that you can’t win in the long run, some still don’t know, and those that are oblivious to this fact are loved by casinos.
5. Max betting is the best option
This one may seem counter-intuitive but it’s true. On most slots, max betting activates all the bonuses and jackpots and increases your odds of getting lucky and winning, which makes it the best option for players.
Although it doesn’t make too much of a difference, it still creates more favorable conditions for the player. The casinos don’t want you to know this because they want you to bet small and more often at a worse payout rate, which makes them more money in the long run.
One thing you certainly don’t want to do though is max-bet above your bankroll and burn through more money than you intended to. Playing more than you can afford to lose is playing right into the casino’s hands. If you can’t afford the max bet on a slot then drop down in denominations or move to a machine where the max bet is smaller and works within your bankroll.
6. Class 2 slots aren’t really slots at all
Sometimes you’ll come across slot machines that are classified as class 2 slots. These are usually found on native Indian reservations or racinos in the United States.
These aren’t traditional slots like what you would find in Las Vegas. Vegas slots are Class 3 slots and are proper slot machine games.
Class 2 slots are actually pre-programmed bingo games which present a slot face for entertainment purposes. Class 3 slots are usually illegal in the jurisdictions that have these slots bingo games, so game manufacturers and casinos combined their forces to come up with this alternative.
Sometimes you’ll see a small bingo card on the bottom corner of the screen which will straight away tell you that this is a class 2 slot machine. So, be warned, these machines are not slots at all and you’ll be effectively playing computer bingo when you start spinning on these.
7. Video slots pay out less than classic slots
Big fancy video slots will almost always pay out less than classic reel slots. This is because of the fact they’re more entertaining, draw more players and action, and cost the casinos a lot more to run and maintain.
These big machines often take up two to three times the amount of space compared to classic slots and tend to cost the casinos a lot more to keep them running. In order to maximize profits, the casinos will then dial down the payout rate on these machines so they still make enough money on them.
Immersive video slots are a huge moneymaker for the casino, so don’t go in thinking you have the same chance of winning on these compared to traditional old school slots. If you’re looking for better chances to win on slot machines, then stick to the classic slots.
8. Slots are completely random
How Do Slot Machines Work Reddit
Casinos don’t want you to know this, but slot machines are completely random in nature. Although they are weighted to pay out at a certain rate, this is still in line with the randomness of results that a slot will produce.
Each spin is completely independent of the previous spin. As an example, if you were to win the jackpot on one spin, then the likelihood of winning the jackpot on the next spin is exactly the same. No previous events impact future events. This isn’t how they work.
Casinos don’t want you to know this because they want you to think slots are “hot” or “cold”, because that will cloud your judgment in respect to how much you play and gamble. This works out better for them in the long run so they are happy for these myths to grow and spread.
9. All of your play is tracked
From the moment you sit down at a slot and enter your player card and cash, every movement you make is tracked automatically by the casino. Slot machines are now networked and have sophisticated hardware and software to track everything you do.
This information is collected, analyzed, and insight reports are developed and delivered to the casino marketing department so they can work out the best possible way to market their casino and slots to you so that you keep coming back and play more. If you don’t want your play tracked then simply don’t use your player’s card, but then you won’t get any casino comps.
In the near future, if it’s not being used already, casino marketing departments will start using security infrastructure to monitor and track your play irrespective of whether you use your card or not. Facial recognition programs will detect you, associate you with a player’s card or create a new player account and track everything you do on a video feed.
This is a bit scary and it shows the lengths casinos will go to. If you play online, everything is tracked under your player account, so it’s easier for online casinos to monitor what you do in this respect.
10. Payout tickets are more likely to be put back into a machine
Over the past 20 years, casinos have slowly phased out cash payouts at slots. These days you’ll likely receive a ticket when you cash out, which you then must take to a cash-out machine or the cage to exchange for cash.
While the casinos will claim this is for your convenience, one of the main reasons they’ve made this change is to disassociate you from the fact you’re holding money. This is similar to what they do with chips on table games.
Psychological studies have proven that people are far more likely to gamble more with a ticket or chips, as opposed to cash. So don’t be fooled into placing your ticket into another slot on the way to cashing out, they’ve done this on purpose. I’d recommend that you always cash the tickets out for cash every time, instead of keeping it for play later.
11. Slot arms don’t exist as much anymore because they slow down play
Back in the day, pretty much every slot machine had an arm, or lever, that you pull to activate the spin. These days it’s much harder to find machines that have these.
How Do Slot Machines Work
While there are a few reasons for this, the main reason and the one the casinos don’t want you to know is because using a lever is much slower when compared to pressing a button. Casinos want you to be playing as quickly as possible when it comes to slots because the more you spin the more the odds move in their favor.
So by having buttons instead of levers the game moves a lot faster. Some may even say they’ve removed the lever so people don’t refer to slot machines as one-armed bandits anymore, but that may just be here-say.
12. Games are designed to be played as fast as possible
As we touched on in the previous secret, casinos want you to play whatever game you’re on as quickly as possible. While one of the main measurements on a slot is the time spent playing, they also want you to play as quickly as possible.
This increases the yield on the machine for the casino, meaning they make more money. Consider this, if you have a bank of widely popular slots which many people want to play, and it takes 20 seconds per spin, that’s quite a lot of time.
If a spin takes five seconds then you’re getting four times the amount of play on that machine which results in much more money passing through. So, all the time the casinos are trying to think of ways to make games happen much faster. They don’t want you playing slowly, so make sure you take your time next time you sit down at a slot. After all, the more time you play the more entertainment value you get.
13. Slot sounds and graphics are designed to make you feel happy
One thing that casinos certainly don’t want you to know about is the fact that slot machine manufacturers have teams of psychologists and researchers that provide advice on what sounds, colors, movements and graphics to use in games in order to make the player feel as happy as possible.
This is both good and bad. Firstly, it’s good if you’re playing for entertainment’s sake and know your limits when it comes to how much money you’re willing to play with. If this is the case then why not play a game that’s designed to make you feel happy.
Secondly, it’s bad when it comes to problem gamblers who don’t know when to stop and are chasing that happy feeling that the games give them. So this is a two-way street; that’s for sure. Casinos probably don’t want you to know this because it isn’t a great look.
14. Sometimes a win isn’t a win
One recent trend on slots is to play a jingle and show an animation showing that a player has had a win; this used to be a good thing and it meant you were making a profit, but not so much these days.
Much to the ire of lawmakers and the regulators, slot machines now play this jingle and imply a win, even when the spin results in less money won than you actually wagered on that spin in the first place. So this is essentially a loss and it’s trying to trick the player into thinking that they won.
Regulators are trying to have this outlawed but it will take some time. So, next time you’re playing don’t be fooled by the animation and sounds and the on-screen advice that says you’ve had a win. Make sure you check how much you ‘won’ when compared to how much you bet, before you celebrate.
15. Major progressive jackpots are played across multiple venues
Have you ever walked past a progressive jackpot slot machine and stared in awe at the huge jackpot which is currently available and is running into the millions of dollars?
If so, then you may not be aware that these slots are actually linked nationwide and the jackpot is played across thousands and thousands of machines and the casinos actually have no part in this prize.
Casinos don’t want you to know this of course; they want you to think that it’s just that machine so that you sit down and play and spin away thinking that you’re the only person who could possibly win that prize at that time.
These major progressive jackpot machines actually take a small cut from each bet you make and divert it to the major jackpot. So you should never play on one of these unless your ultimate goal is to win the life-changing money, and there’s certainly nothing wrong with that.
Conclusion
Casinos are designed to make money just like any business. The slot machines are a big piece of the profit puzzle so the casinos do everything they can to make them more profitable.
Now that you know these 15 slot machine secrets the casinos don’t want you to know you can gamble as an informed player. If you love slots there’s no reason to stop playing, but you should know these secrets before you play again.
