Providing that slots you’re playing are licensed by a recognized body, there’s no way an online slot can be rigged. They may have a house edge, but try and find me a slot, online or elsewhere, that doesn’t. Probably one of the most common questions asked by gamblers “Are most electronic slot machines rigged” the answer is Yes and No. Depends on your definition of the term “rigged.” If your definition of “rigged” is that the casino is guaranteed to make money off electronic slot machines over a long period, then yes.
If you've ever contemplated spinning the reels of a slot or have, in fact, spun one (or a few!), you've probably asked yourself a few questions every serious player in the iGaming industry has - can slot machines be rigged to trick the player, what are the odds of winning slots, are slot machines honest, and do casinos manipulate slot machines at the player’s expense.
Today, I’m going to answer another reader question which I received recently by email. It comes from Sarah in Scotland who wants to know “Are slot machines rigged?” I’ve copied the email directly below with her permission.
Dear GamblingSites.org team,
I’m Sarah McKeown, and I’ve been a long-time reader of your blog. I’ve found lots of interesting content over the years. I even won a healthy jackpot after playing one of your recommended jackpot slots.
However, I’ve been keeping a record of my bets versus my wins, and I’ve noticed that no matter how many big wins I have, I always end up losing it all again over the long term. Can you tell me if slot machines are rigged? Can casinos fix slot machines to make sure players lose?
Any insights you can share with me would be greatly appreciated.
Thanks,
Sarah McKeown
Sarah, I’m going to answer your questions directly. Yes, slot machines are rigged. However, they’re not rigged in the way you think they are
In this post, I’ll explain how slot machines work, why you lose in the long-term, and I’ll give you some useful tips for beating slot machines more often. Let’s begin!
Are Casino Slot Machines Rigged?
I guarantee you that if you walk through any Vegas casino, or any casino in the world for that matter, and ask every slots player if they won, the vast majority of them will tell you no.
It’s difficult to understand how this could be the case unless slot machines are rigged. And if they are, how in the heck is that legal? Are casinos actively keeping slot machines rigged so that you can’t win? If so, what about all those stories of players who won huge jackpots?
This can all seem rather confusing, but it’s not. The simple answer is that the vast majority of players lose, and a few lucky players win. Each machine is programmed to pay out less than what’s put into it, ensuring that the casino makes a continuous profit over the long run. This could be anything from a 2% advantage on the best slot machines, to a 10% or greater advantage on some of the big-money jackpot slots.
So, in a nutshell, casino slots are rigged to make sure the casino makes a profit, but that does not mean you can’t win on any given gaming session.
Gaming commissions would never allow casinos to run games you can’t win, nor would it be good for business. Players would soon figure out that the games were unwinnable and would stop playing.
Let’s take a closer look at how slot machines work. This will help you understand that while the house always wins, you can win, too.
How Slot Machines Are Rigged
Understanding how slot machines are rigged requires you to understand how they work. Each slot has its game odds, but they all use a similar method of paying out jackpots. Here are some important things to know about slot machines.
Understand Slot Machine RTP
RTP is an acronym for “return to player.” If you read slot machine reviews, you’ll usually find each game has a specific RTP published by the developer. For example, on NetEnt.com, you can find the RTP of Starburst and other games.
RTP is a percentage.
For Example:Based on Starburst from above, the RTP is 96.09%. What does this mean in terms of money, jackpots, and wins and losses? It means that, for every £100 bet on these games, players win back £96.09.
It’s important to remember that this does not mean you’ll make back £96.09 for every £100 you bet on Starburst. It means that the casino returns £96.09 to all players spinning the reels at every casino which offers Starburst. This includes all of the small wins and losses each player wins on every spin. In the long run, the casino will make £3.91 on every £100 bet on that game, regardless of what happens in the short term.
Hopefully, this concept of RTP helps you understand how slot machines are rigged in favor of the game developers and casinos but are not rigged in absolute terms. You can win when playing slots, but you can’t win in the long run.
Understand Random Number Generators
Even though the house has a built-in advantage on slot machines, it’s clear that some players do win massive jackpots. Just take a look at this story about a British soldier winning a record-breaking jackpot from a £0.25 spin.
Lots of players wonder when the best time to play slot machines is, which slots are “loose,” and all sorts of other questions. They hope that figuring out the answers will help them win slots more often, but the truth is that this is all a waste of time.
Slot machines decide when to pay out in accordance with a Random Number Generator (RNG). Believe it or not, it’s possible for a slot machine to pay out a jackpot on two spins in a row, although it is unlikely. A Random Number Generator is a piece of software which spits out billions of numbers per second, and if it happens to spit out a number associated with a jackpot, you’ll see the high-value symbols line up across a payline and you win.
There’s no way to manipulate RNGs. You can’t cheat online slot machines no matter how hard you try. Some smart players note that RNGs can’t be truly random since humans create them, but for all reasonable and practical purposes, you can’t manipulate them.
Perhaps, someone will someday spot a pattern in the apparent randomness by using a quantum computer to crunch numbers. But until then, just assume they’re random.
While the slots developer can control the RTP via programming, it can’t control the RNG. There are third-party games testing organizations such as eCogra which test RNGs and verify that they are fair. This doesn’t mean all slots developers play fair, but big names like Microgaming and NetEnt do.

How to Win at Slots — Tips and Tricks
Now that you understand how slot machines work, and how they are rigged without being unfair, it’s time to turn the tables on the casinos. I’ve learned a lot about slot machines throughout my career as a player, and I’m going to share my best tips on how to win slots more often.
Pick Slot Machines With a High RTP
One of the first and most obvious tips is to select high RTP slot machines. These games pay back the most to players in the long run, so you’re better off playing them even if the jackpots are smaller.
Very often, the jackpots are smaller. Since the casinos have less risk to deal with when a smaller jackpot is involved, they can afford a higher payback percentage to players. It makes sense, doesn’t it?
So, which slot machines have the highest RTP? Here are five to get you started.
- Blood Suckers by NetEnt – 98%
- Rags to Riches by Cryptologic – 98%
- Good Girl, Bad Girl by Betsoft – 97.8%
- Kings of Chicago by NetEnt – 97.8%
- Wolfpack Pays by NextGen – 97.8%
Those slots have a variety of excellent bonus features, decent jackpots, and higher than average RTPs. If you want to get the most bang for your buck as a long-term player, it’s wise to play them.
Pick the Right Volatility for Your Bankroll
There’s a top-notch article on slot machine variance and volatility here. If you want a more detailed breakdown of what they are, check that out.
Slot machine volatility is important to understand because it will tell you which slots are suitable for your bankroll. Volatility indicates both how often a slot should pay and the average size of the payouts.
- Low volatility slots pay smaller amounts more often.
- Medium volatility slots pay decent amounts fairly often.
- High volatility slots pay less frequently, but wins are more explosive.
If I had a smaller bankroll, say £20, I’d start by playing a low volatility slot such as Starburst. I find that it’s a good slot to build your bankroll with. Once I double up, I usually switch to a higher volatility slot with bigger payouts which occur less frequently.
Managing your bankroll effectively is about the only slot machine strategy which works. Therefore, knowing the volatility of a game is useful information.
Use Free Spins With Low Wagering Requirements
Most online casinos offer free spins bonuses for new players. Lots of them also offer free spins to loyal players who spin slots daily or weekly.
I’ve learned the hard way that not all free spins bonuses give me an advantage. Sometimes, the wagering requirements are so high that the bonus is a liability. This is especially true if it comes with predatory terms such as that I can’t withdraw my deposit until I meet the wagering requirements. Yes, such bonuses exist, I’ve seen it all over the years I’ve been playing!
There are other free spins bonuses you will want to take. They’ll give you a chance to beat the house with its own money and have these characteristics.
- They won’t require excessive minimum deposits.
- The wagering requirements will be low, around 20x or less.
- You’ll be able to keep all of what you win when you wager the bonus.
Free spins with low wagering requirements are available at lots of top UK casinos. There are even casinos with no wagering requirements, and they’re especially popular in the UK market.
Final Words
Thanks for writing to me with this question, Sarah. It’s given me a chance to cover lots of ground with regards to slot machines, and I hope that it answers your question. Are slot machines rigged? Yes, the house has a mathematical advantage which you can’t alter, but that doesn’t mean you can’t win.
Beating slot machines is a case of picking the right games, managing your bankroll effectively, and getting lucky. Don’t forget the last part! Luck is essential. There’s no effective way to beat the slots every time. Happy spinning, and don’t forget to pick up a casino bonus before you begin!
Please enable JavaScript to view the comments powered by Disqus.The first thing a losing customer will say is that the slot machine is rigged, whether it is at a land-based casino or at an online gambling center. We tend to make ourselves victims of injustice more often than never, especially if we don’t understand how some things work and don’t have either the time or the will to investigate.
This happens to be the situation with online slots and some people thinking they are, in fact, rigged. Skepticism is not always bad, it is like a form of a precaution, and fully understandable when it comes to gambling with real money. But let’s see why the theory about rigged online slot machines doesn’t have any substantial arguments to support it.
Mechanics made way for electronics
Slot machines are still experienced as machines, even though computer software was taken over and altered slot technology. Sure, slot machines were simpler in the past, you pull the lever and hear the cogwheels tuning inside, but past is the past. Nowadays, software stands behind both land-based machines and online slots, so they pretty much work the same way.
If you think online slots can be computer programmed to make players loose, well then the same logic can be applied to brick and mortar slots, as you are playing all the same games but channeling them through a different device. However, slot game software can’t be manipulated in that way, due to various reasons – such as constant supervisions and testing.
RNG and regulation
In order to understand how hard it would be to rig online slots, one should know that slot software is operated by an algorithmic computer whose task is to create random combinations through series of random numbers. It is known as Random Number Generator, or simply RNG.
RNG carries out operations following an algorithm of mathematical operations starting from one random number and ending up at a completely different number containing a huge number of digits, them repeating it times on end, making it impossible to predict any future or past actions.
The computer has no input of past spins and every reel combination is random.
You can lose if you’ve lost ten times before, or you could win again if you’ve won big on your last spin – there’s no way to tell.
RNG is in charge of producing randomness, and third party testing companies are there to control fairness of casino games, including online slots.
These companies are independent third parties and their job is to make sure games show random results and meet payout percentage requirements, as in some jurisdiction these are determined by lawful regulations. An example would be Technical Systems Testing (TST).
Apart from this, government bodies like the UK Gambling Commission, Jurisdiction of Gibraltar, the Malta Lotteries and Gaming Authority and others, function like supervisors and impose rules and regulations both software developers and casinos have to meet in order to acquire a respected casino license to operate.
Regulatory agencies provide casinos with proper certification so the players can keep their piece of mind.
Software isn’t bug-free at times
What every customer indulging in services of any type of computer software has to know is the fact that sometimes these things have bugs, and malfunction or crash.
Computers aren’t made by computers, but by humans, and some of these products fail to satisfy users at one point or another.
Such cases are known to happen, for example last month a woman thought she had won almost $43million in a New York casino on a slot machine that had a max payout of $6,500 before the management informed her that the slot was broken and had to be pulled from the casino floor to be fixed.
Similarly, a woman in Oregon thought she had won $8 million, but the casino didn’t pay since it was evident the machine was broken, having a max payout of just $20,000.
These things make customers bitter, but they are by no means signs or rigging. All machines have a stamp on them that says: ‘malfunctions void all pays and plays.’
Something to think about
There is a very good advantage attached to online slots that grounded slot machines lack. We’re talking about the theoretical payout rate, the payout percentage, or simply RTP. This is an official piece of information about a specific slot, being published by the developer or the casino.
RTP is a legitimate indication of the odds of winning when playing a slot. It is expressed in percentages, telling you precisely how much a slot is estimated to pay back to players.

This means you don’t have to be clairvoyant to know what to expect from a slot, just stick to reputable, licensed casinos and slots with higher RTP.
As you saw in our casino software section, most of the companies publish their official RTP rates, as this is a standard for most European oriented casinos.
For USA players the situation is a bit more difficult since many software companies do not post official data, such as RTG for example. In those cases where official RTP rates are not published, we recommend to search for a third party testing company monitoring that particular online casino. Otherwise, you can check the review section mentioned above, where we recommend the best RTG casinos with instant payouts. And if you are not particularly into RTG slots, then you can go with Rival or BetSoft casinos which publish the payouts of most of their games.
