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
Jul 28, 2011 To play slot machines, play the multiplier machine by betting a small amount to try and win a small amount or a large amount to try and win a large amount. Alternately, play the buy-a-pay to bet more money in return for more chances of winning rather than winning a larger amount of money. Slot machine tips - Guidelines on how to use slot machines, how to get the most for your money, machines to select and handpay guidelines. 13 Free Things to Do in Las Vegas Information on the top free things to do in Las Vegas, which I feel should not be missed due to a lack of awareness. Tips for Wining Big on Slot Machines. Use your Player's club card Play two-coin, three reel, one payline slot machines. Stay away from three-coin machines unless they are progressive machines. Don't play more than one machine at a time. Always play the maximum coins. Always play machines that show double up symbols. Don't play nickel slot machines.
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
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.
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.
Las Vegas is home to over 197,000 slot machines. That’s roughly one for every three residents. With so many slot machines to choose from, it should be no surprise that you can find some interesting ones hiding around town.
This is especially true in downtown Las Vegas, known to many as “Old Vegas.” Fremont Street specializes in keeping the old-time feel alive. This is where you will find all sorts of buildings, stores, merchandise, and yes, even slot machines from the early days of Las Vegas history.
Below you will find a list of some of the interesting, fun, vintage, or downright weird slot machines you can find in downtown Las Vegas.
Coin-Operated Slot Machines
Coin-operated slots are one of the most sought-after unique slot machines found in Las Vegas. They bring a bit of nostalgia back to the game. These are getting harder to find. Many casinos have a hard time finding parts for repair, which has caused most to get rid of coin-operated slots altogether.
The evolution of our U.S. currency has had a dramatic impact. The D Hotel and Casino has phased out all of its coin operated slot machines. For a place specializing in vintage slots (they have an entire floor devoted to these), why would they do this?
Turns out, the machine’s bill reader cannot recognize our newer versions of U.S. currency in $5 and $20 bills. These bill readers cannot be swapped, and old currency is hard to keep in supply. All of this works out to be too much of a headache for the casino.
With that said, there are still a few places in downtown Las Vegas that offer the chance to play coin-operated slot machines. They are:
- California Hotel and Casino
- El Cortez Hotel and Casino
- Fremont Hotel and Casino
- Main Street Station Hotel and Casino
- Plaza Hotel and Casino
Sigma Derby
Sigma Derby is a retro horse racing game. It made its debut in 1985 and was quite popular at the time. In today’s casinos, it’s nearly impossible to find. Just like coin-operated slot machines, parts for Sigma Derby games are hard to find when the game is in need of repairs.
In addition to having a difficult time keeping the Sigma Derby machines operational, the casinos make a very small profit on them. They are coin operated and run on just a few quarters. The machines also take over a minute to complete one round.
Because of this, almost every Las Vegas casino has done away with Sigma Derby machines. In fact, there is only one such machine in all of downtown Las Vegas. This machine is at The D Hotel and Casino. Or, if you’re willing to venture to the Las Vegas Strip, there is one other Sigma Derby machine located at the MGM Grand.
Silver Strike
Silver Strike slot machines have an incredible fan base. They appeal to both slot machine players and to collectors. This is because, rather than winning cash, you win silver coins. Well, partially silver coins.
The coins used to be .999 silver. Now they are usually a mix of silver and copper. The variance is due to the fact that each casino is responsible for producing their own silver strike coins. This brings in the collector’s aspect, as there are many different coins to try to win.
The machine has a $3.00 max spin, which you must bet to have a chance at the silver coin bonus. If you get a silver strike logo on the third reel, you win a silver strike coin. Most of these coins are worth roughly $10; however, you have a chance at randomly receiving one worth up to $300.
There are varying values within each casino, plus several different casinos offering their own coin variations. The cost associated with producing the silver strike coins has deterred many casinos from carrying the machines. In downtown Las Vegas, there are two casinos who still have the game on their floor:
- The Four Queens Hotel and Casino has four machines
- El Cortez Hotel and Casino has one machine
Jumbo Slot Machine
The Golden Nugget Hotel and Casino is home to one of the largest functioning slot machines in all of Las Vegas. This slot machine is over eight feet tall! It is a 4-reel machine that works in dollar denominations. You will find this slot machine in the lobby by their front entrance. Such a massive machine can draw a lot of attention. It’s not unusual to see a crowd surrounding the machine, watching the player.
It does have an arm mechanism on it; however, this is no longer how the slot machine reels are spun. This is done with a spin button. One old-time aspect that still remains is that the payout from the machine is given in quarters. It’s a fun experience everyone should try once.
Vintage Slot Machines
If you’re looking to see some gambling history, Las Vegas is the place to do it. Even more specifically, looking through downtown Las Vegas, where the city got its start. Fremont Street is where the big casinos of Las Vegas originated. It is where it all began in the evolution of what Las Vegas is today.
This rich history is displayed throughout downtown Las Vegas. One of the crowd favorites in nostalgic merchandise is slot machines. There are two displays featuring retired, vintage slots. These are no longer functional but are still amazing to see. They are located at:

- The Golden Gate Hotel and Casino
- Main Street Hotel and Casino
If you’re looking for a large selection of vintage slot machines you can still play, your go-to destination should be The D Hotel and Casino. Their entire second floor is devoted exclusively to vintage slot machines. While they have all been converted to TITO (Ticket In/Ticket Out) machines, they still maintain the vintage gameplay options.
SlotZilla Zip Line
If you’re looking for unique slot machines that you can wager money on, the SlotZilla slot machine on Fremont Street is not for you. That’s because it’s not actually a slot machine, but a giant model of a slot machine. In fact, it’s the most giant one in the world. The SlotZilla slot machine holds the world record for the largest slot machine, standing at 128 feet tall.
Youtube How To Use Slot Machines In Las Vegas
It is truly a sight to see. It doesn’t stop there, though. The SlotZilla machine is actually a zip line. The zip line originates at the top of the 12-story-tall slot machine replica. From there, riders will fly down Fremont Street, just below the lighted canopy. There are two versions you can try: the zip line and the zoom line.
Conclusion
If you’re looking for something slightly different to do in Las Vegas, or simply trying to change up your usual gambling routine, this list has you covered. Everything on this list should be seen once if you’re a fan of slot machines or Vegas history.
Not only will you be able to play some of the oldest functioning slot machines around, but you will also get to see amazing pieces of Las Vegas culture. You can cap it all off with a ride on Vegas’s own slot machine zip line.
