Once a specific casino has been determined to currently be the best of any available, choosing slot machines becomes the next step towards making a profit at slots.
Remember, statistics supplied to state gaming commissions show that the odds of winning are, on average, somewhere around 90%. By assessing all available casinos, then selecting the best possible, you’ve already improved your odds of winning – perhaps by several percentage points.

Whatever your gambling goals are, we’ll talk about those in the next step Identifying Gambling Goals. For now, we need to consider choosing slot machines that will most likely improve our overall odds even more.
So, we’ve walked into our best casino to choose slot machines with the highest odds of winning we can find. How do we select a good slot machine? Most people don’t – they dive right in without much of a plan. Well, we have a plan.

Why? Because everybody says it’s all about luck. If you pick wrong, “Well,” they say, “better luck next time.” Remember, casino employees are trained to say things like that. If you’d won a jackpot instead, you can believe they would have said, “You’re lucky! I’ll see you later when you win another jackpot!”
Slot attendants have a job to do, and it most certainly isn’t to get you to leave when you should. And, it’s difficult to not to influenced by such comments. But, try not to be.
In the following sections, I’ll briefly explain the following aspects of choosing slot machines:
- How odds are set within a slot machine
- Choosing denomination and maximum credits based on bankroll
- Basics of reading a slot machine’s paytable
- A simple way to use paytables to pick the best machines, and avoid the worst
Two Separate Odds of Winning
The odds of winning for a slot machine is a limited number of settings from the manufacturer. Besides understanding limited settings are available, it may help to understand that slot machines have two odds of winning to determine:
- If a player will or will not win anything
- How much that win will be, i.e., the jackpot amount
Why is understanding these two types of odds significant when choosing slot machines? Because winning slot machines come in all jackpot sizes. You’re still winning if you’re getting enough small jackpots that your bankroll isn’t shrinking. Even if it is slowly depleting, the bankroll can last quite a bit longer, so that’s also a winning slot machine.

Winning many jackpots this way is bankroll cycling. It may not seem very satisfactory, but whether it does or not depends entirely on what your gambling goals are. One type of gambling goal, earning maximum complimentary gifts, is most often achieved via bankroll cycling.
Another point about setting slot machine odds is, how often they change? Of course, it depends on the age of the casino, as discussed in the previous step Assessing Casinos for Success, or if it’s been renovated lately.
Free Slot Machine Play
In my experience, older-style casinos change their slot machine odds every 7-10 days. Newer-style casinos can change their slot machine odds whenever the machine has been idle for 15 minutes or more, without a players club card inserted or the machine temporarily locked by a slot attendant.
Matching Bankrolls to Denomination/Credits
Only you can decide how much bankroll you want to risk gambling. I highly recommend bringing only as much money you can safely afford to lose comfortably.
Bankrolls quite literally determine which slot machines you can play. But, there’s more to it than understanding a $100 bankroll lets you play a 1-credit, $100-denomination exactly once, with very, very little chance of winning.
Whatever bankroll you have limits which slot machines can be played and how much it can be played. Slot machines have denominations ($0.01, $0.25, $1, $5, $10, etc.) and the maximum credits that can be placed in a single bet.
Slot machines typically must run for a while before wins become more likely. Yes, wins can occur at the first press of a button. They can also happen within the first few bets, where casinos offer a taste. But, usually, they need to run for a while.
About 100-120 bets is the right amount to be prepared to play to determine if you’re sitting at a winning (or breakeven) slot machine. Yes, be careful initially, perhaps making as few as 20 bets, to determine if it happens to be a “bad” machine. Trust your instincts!
If it is a poorly performing machine, a “tight” slot machine, it won’t pay out anything at all. Quick decisions are necessary here, so limited betting gives a clue to its performance, yet still leaves enough to gamble with on another machine if it isn’t – assuming you stop playing it as soon as you notice it’s not performing well enough.
So, again, you determine how much bankroll you can afford to spend. Now, take that number and divide it by 120 bets. If your bankroll is $60, then that’s 50 cents per bet. In such a way, the right choice is a 2-credit, quarter-denomination slot machine. Or, a 50-credit, penny-denomination slot machine.
Always remember to play maximum credits for the highest odds of winning. Meaning, your casino may not have a 2-maximum-credit quarter or 50-maximum-credit penny machines. But, perhaps they have a 1-maximum-credit quarter or less-than-50-maximum-credits penny machines. Such slot machines would provide more than 120 bets of play, which is going in the right direction!
Reading a Slot Machine’s Paytable
When choosing a slot machine to play, a crucial aspect of winning is to review its paytable before playing. Frankly, the casino industry gains an advantage over players that don’t read slot machine paytables.
Located somewhere on a slot machine is one or more tables showing the number of credits won if specific combinations of reel symbols appear in the pay line after the player makes a bet. Below is a relatively generic example of a paytable.
The figure shows reel combinations along with their jackpot depending on the number of credits bet. Paytables don’t typically explain how much credits
Not every reel combination and its associated jackpot are usually shown in a paytable. Other reel combinations not shown in the top rows are also presented in the paytable area. Slot machines with WILD symbols can represent it with a myriad of other possible reel symbols.
A final element of paytable example provided is specific information on winning reel combinations, which can include an indication of how the slot machine operates during play. The bottom row of symbol explains that that slot machine has reel symbols which will move after the reels stop momentarily.
Such additional features may not activate until the maximum credits are bet. It can sometimes be difficult, or impossible, to determine this. Most slot machines with bonus rounds will provide at least some information about it within its paytable.
Developing a habit of reviewing and studying a slot machine’s paytable can help improve your ability to judge the financial risks involved with playing that slot machine.
How to Avoid the Worst Slot Machines
The best way to improve the odds of winning via slot machine gambling is to stop making “sucker bets”. In less colorful language, avoid playing slot machines with terrible odds of winning.
First and foremost, understand when choosing slot machines that there are indeed terrible slot machines at a casino. By merely avoiding them whenever possible, on average, your long-term gambling return will improve. Each time we raise our odds like this, we’re pushing closer to achieving our gambling goals. So, let’s make sure we do that, shall we?
Calculate this “Goodness Ratio” as follows:
- When choosing slot machines, as discussed above, find the paytable with the denomination and maximum credits that best matches your available bankroll.
- Take a close look at the paytable. What is the maximum possible jackpot when maximum credits are bet?
- If the top jackpot is displayed in currency, divide it by both the denomination of the machine and the maximum credits
- If the top jackpot is displayed in credits, divide it by only the maximum credits
This “Goodness Ratio” tells us how worthwhile a specific slot machine is to play relative to others. By using this approach, any slot machine can be compared to any other slot machine.
Example: In the paytable above, the maximum jackpot is 2,400 credits with three maximum credits. Therefore, its Goodness Ratio is 2,400 / 3 = 800.
Repeat this calculation for slot machines of interest. While this Goodness Ratio will be similar for many slot machines, it can be startling to find “sucker bet” slot machines that might not otherwise be avoided.
Summary for Choosing Slot Machines
After a casino has been chosen, it’s time to select candidate slot machines most likely to result in a relatively high-value win. The size of your available bankroll, whatever it is, is an essential factor in this selection process. The bankroll size needs to be matched to the slot machine’s denomination and the number of maximum credits.
Here, we’ve also discussed how slot machines calculated odds twice: once to determine if you’ve won, and again to determine how much you’ve won. Another critical aspect discussed to improve a player’s performance was the basics of reading a slot machine’s paytable.
Finally, we talked about the “goodness” ratio to help select candidate slot machines and, perhaps critically important when improving our odds of winning, knowing precisely which slot machines must be avoided.

One of the most common questions you’ll see about anything in the casino gambling industry relates to “honesty”. You’ll see this question asked about every casino game under the sun. You’ll also see it asked about every casino, especially the online gambling sites.
In this post, I want to address this specific question:
Are slot machines honest?
How Do You Define Honest?
When I use Google to look for a definition of honesty, I see some of the following definitions listed:
- “Free of deceit and untruthfulness”
- “Sincere”
- “Morally correct or virtuous”
- “Fairly earned, through hard work”
I think most people are thinking of the first definition when they ask whether slots games are honest. They want to make sure they’re not being cheated. In this context, the answer is yes, slot machines are honest. I’ll explain why in detail in the rest of this post.
In the second context, where “honest” means “sincere”—I’m less sure. Are the casinos sincere when they want you to think you’re able to win money? I think so, but they know in the long run, anyone who plays slots long enough will lose all their money.
In the third and fourth contexts, I’d have to say that slot machines are NOT honest. Slot machines are closer to morally neutral than they are to sinful, but you might have a different belief system about such things. It’s hard to say that slots don’t appeal to one of the seven deadly sins, though (greed).
I’m not sure anyone could (or would) consider money won on a slot machine “earned” or to have anything to do with “hard work”. It’s a game of luck. If you win, then you got lucky—it has nothing to do with working hard or being smart.

How a Slot Machine Works Mathematically
Answering the question “are slot machines honest?” begins with learning how the games work mathematically. The math behind the games is easier to understand than most people probably think.
The first concept to understand is basic probability. When someone says “probability”, they’re talking about the mathematical likelihood that something is going to happen. That “something” is called an event.
The probability of an event is always represented as a number between 0 and 1. An event that will always occur no matter what has a probability of 1. An event that will never occur has a probability of 0. An event that will occur half the time has a probability of 0.5.
For simplicity’s sake, and to make understanding the concept easier, I just used whole numbers and decimals in the previous paragraph. But probabilities are almost always expressed as percentages or fractions.
How to Express Probability as a Percentage
You’re watching the evening news, and the meteorologist says there’s a 50% chance of rain tomorrow.
That means it’s just about as likely to rain as it is to not rain.
Here’s another example:
You flip a coin. You have a 50% chance of it landing on heads. You also have a 50% chance of it landing on tails.
If you add the probabilities of all possible events together, you always get a total of 1 (or 100%).
Probability is the mathematical engine that makes gambling games possible.
How to Calculate a Probability
Here’s how you calculate a probability:
You take the number of ways an event can happen. You divide that by all the total events possible (including what can happen and what happens if it doesn’t.)
You’re rolling a single six-sided die. You want to know the probability of getting a 6.
There are 6 possible outcomes. Only one of them is a 6.
The probability of getting a 6 is 1/6.
Another way to express that is using odds, which can be useful when calculating whether a bet is expected to be mathematically profitable or not.
Odds expresses the number of ways something can’t happen versus the number of ways it can happen.
In the six-sided die example, the odds of getting a 6 are 5 to 1. You have 5 ways of NOT rolling a 1, and only 1 way of rolling a 1.
If you want to calculate a probability that includes the word “or”, you add the probabilities of the events together.
If you want to calculate a probability that includes the word “and”, you multiply the probabilities by each other.
You want to know the probability of getting a 1 or a 2 on a roll of a six-sided die. The probability of each is 1/6.
1/6 + 1/6 = 2/6
You can reduce that to 1/3.
Here’s another example:
You roll 2 dice. You want to know the probability of getting a 6 on both dice. The probability of each is 1/6.
1/6 X 1/6 = 1/36
Applying Probability to a Simple Hypothetical Slot Machine Game
But how does all this apply to the honesty of slot machines?
I’ll use a super simple hypothetical slot machine game to explain how this probability affects the integrity of the game.
This super simple game has 3 symbols on each reel—an orange, a lemon, and a cherry.
The probability of getting a lemon on the first reel is 1/3.
The probability of getting a lemon on the second reel is also 1/3.
In fact, it’s the same on each reel.
But the game only pays off if you get 3 of the same symbol on each reel.
The probability of that is 1/3 X 1/3 X 1/3, or 1/9.
Let’s suppose the payoff for getting 3 lemons is 4 for 1.
And let’s suppose the payoff for getting 3 cherries is 3 for 1.
Finally, we’ll suppose the payoff for getting 3 oranges is even money.
- The probability of winning 4 coins is 1/9.
- The probability of winning 3 coins is also 1/9.
- The probability of winning 1 coin is also 1/9.
- The probability of winning nothing is 6/9, or 2/3.
Now let’s suppose you’re putting $1 in on every spin, and you play 9 spins, getting every possible result once.
You win 4 coins once. You win 3 coins once. You win 1 coin once. That’s a total of 8 coins you’ve won.
But you’ve inserted 9 coins into the game.
Where did the extra coin go?
In the pockets of the casino, that’s where.
By setting up the payoffs so that they’re lower than the odds of winning, the casino sets up a situation where it’s guaranteed a mathematical profit over the long run.
Of course, most modern slot machines aren’t quite this simple. They have more symbols on each reel, for one thing. For another, the probability of getting a particular symbol might be different from the probability of getting another symbol.
For example, you might have a 2/3 probability of getting a pear, and only a 1/24 probability of getting a cherry.
What Happens in the Long Run vs. the Short Term?
By manipulating the payoffs and the probabilities of the symbols, the casino can guarantee that over a long period and many spins, they’ll profit.
But in the short run, a player might win a big jackpot or lose several times in a row.
That’s the nature of random events. In the short run, anything can happen. In the long run, the numbers get closer to the theoretical probability.
This is obvious when you look at it with an extreme example.
On an infinite number of spins, your average loss per spin will mirror the mathematical expectation.
The closer you get to an infinite number of spins, the closer you’ll get to the mathematical expectation.

Do Slot Machines Cheat?
The casinos don’t need to cheat to make a healthy profit.
The slot machine designers and manufacturers don’t need to cheat to make a healthy profit.
In fact, in well-regulated jurisdictions (like Nevada), games are thoroughly audited for fairness. When they’re auditing a game for fairness, one of the things they check is whether a game has a jackpot that’s impossible to win.
That’s the main concern many players have when they ask if slot machines cheat.
Does the game have jackpots that are impossible to win?
The short answer in almost every case is no, they don’t.
But you have no way of knowing what the probability of winning that jackpot is. Slot machine games have opaque odds and probabilities. The results are generated by a computer program called a random number generator (RNG).
The only people who know the exact settings for that RNG are the designers and the casino managers.
In fact, you could be playing two identical slot machines located right next to each on the casino floor and have different odds of winning. Not only is this legal, it’s common.
Does that sound like cheating?
By the strict letter of the law, it’s not.
Is it honest?
I’d say yes. Having two games next to each other offering different odds is intentionally misleading. It’s legal, but it’s not sincere in any way.
Online slot machines are no different, except that in some cases, these games HAVE been known to cheat. But not reputable casinos and not reputable software providers.
How do they cheat?
They set up games which are impossible to win.
The reasons baffle me. You stand to make far more money in the long run if you offer an honest game.
Even an idiot can tell after a while that he’s never going to win a rigged casino game on the Internet.
But otherwise smart people will continue to deposit money and wager it at a breakneck pace if they’re winning something every now and then, even if they’re showing a net loss over time.
That’s how gambling works.
What About Video Poker Games?
You need to understand immediately that video poker games are NOT the same thing as slot machine games. They look similar on the surface, but the math and the gameplay couldn’t be more different. And the philosophy behind these games is different, too.
Here’s why:
A video poker machine uses a random number generator that duplicates the odds found in a 52-card deck of cards. You know the probability of getting a specific symbol. Any specific card has a 1/52 probability of appearing.
A card of a specific suit has a ¼ probability of appearing. A card of a specific rank has a 1/13 probability of appearing.
Payback Percentages and the House Edge
Knowing this enables mathematicians and computer programs to calculate the actual payback percentage for these games.
What’s a payback percentage?
It’s the percentage of each bet that’s paid back to the player on average in the long run. It’s the opposite of the house edge.
On a slot machine, you have no way of calculating a game’s payback percentage. It’s impossible, because you have no way of knowing the probability of getting a specific symbol.
But on a video poker game, you can calculate all the possibilities. And since you know how much the game pays out for various combinations, you can add the expected value of each to get an overall payback percentage for the game.
And you know what’s even better than this?
The payback percentages for video poker games are significantly higher than the payback percentages on slot machines in almost every case.
Even the worst video poker game usually has a payback percentage of 95% or so. But the better games offer payback percentages in the 98%+ range. Some (rare) games have pay tables which offer a slightly positive game for the player, like 100.2%. But those numbers assume perfect strategy on your part.
But even the best slot machine games usually have a payback percentage in the 95% range. The more common games slip down into the lower 92% or so range.
Expected Hourly Loss Rates in Slot Machine Games vs. Video Poker Games
What does this mean to your bankroll?

Let’s look at how much money you can mathematically expect to lose playing 2 different games:
We’ll start with an average slot machine game with a 94% payback percentage. You’re playing for $1 per spin, and you’re making 600 spins per hour. You expect to win 94% of each bet back, which means you expect to lose 6% of each bet.
6% of $600 is $36, which is the amount the casino expects you to lose on this game on average over time.
Then we’ll consider a 9/6 Jacks or Better game which you’re playing with perfect strategy. The payback percentage for this game is 99.54%, which means the house edge is 0.46%.
We’ll assume you’re playing a quarter machine and betting 5 coins per hand. You’re putting a little more money into action on each bet–$1.25. Most video poker players are as fast as slot machine players; they play 600 hands per hour. That’s $750/hour in action.
But with a house edge of 0.54%, your expected loss on that kind of action is only $3.77.
That’s right.
Playing slots costs you 10 times as much as playing video poker.
Video poker offers other advantages over slots, too. One of these is the skill element. You might not want to think about what you’re doing when you’re gambling.
But if you’re anything like me, you want to be able to at least exert a little bit of control over your destiny.
In video poker, you get to do that. The decisions you make playing each hand have a direct effect on your bottom line.
Play your hands well, and you’ll be playing one of the best gambling games in the house.
Should You Play Slot Machines at All?
This is a legitimate question. Should you play slot machines at all?
Here are some pros and cons of playing slots:
Pros:
- You can win bigger jackpots on slot machine games than any other gambling game except maybe keno. If you’re looking for a life-changing jackpot, like you’d see if you won a lotto drawing, slots are the way to go.
- They require little in the way of attention or effort on the part of the player. This suits some temperaments just fine. Relaxing in front of the spinning reels seems like a good deal for a lot of people.
- They’re available in an endless variety. You can find a slot machine game with any theme you can imagine. Love Elvis Presley? You’ll find a slot machine for it. Play Dungeons & Dragons when you were 12? There’s a slot for that, too. The themes and games are almost endless.
Cons:
- They offer some of the worst odds in the house. The house edge for slot machines vary widely. Some of them might offer good odds, but most of them have a house edge of between 5% and 10%. This isn’t awful. After all, roulette has a house edge of 5.26%. The problem is that slots play so fast that you can easily put more money into an action than you thought you could.
- You can’t figure out what the odds are. I have a philosophical problem with slot machine games. No other casino game is opaque about your odds. You can calculate the house edge for any table game in the casino. You can calculate it for video poker, too. But you’re never given the information you need to figure out the house edge on a slot machine. This is unacceptable to me.
- They’re designed to be addictive. Slot machine manufacturers spend millions doing research into what kinds of stimuli are going to put most people into the “flow” state. Flow is great if you’re interested in personal productivity at work, but if you’re playing a gambling game, it’s awful. No other casino game is as addictive as a slot machine.
Conclusion
Yes, slot machines are honest—in a manner of speaking, anyway. Casinos don’t make claims about slot machines that are blatantly untrue. If a game has a maximum jackpot of $1 million, you do have a chance of winning that much money.
What you don’t know is how likely or unlikely it is to win that amount.
Is this disingenuous on the part of the casinos?
I think it is, at least to some extent.
But all casino games have math behind them that puts the odds in the casino’s favor. That’s just the nature of the games. Slots are no different in that respect.
No matter which casino game you play, if you stick with it long enough, you’ll eventually lose all your money.
The only exceptions are certain games that can be played with advantage techniques, but that’s another subject entirely.
The only way for you to get an edge against a slot machine game is to cheat.
In most jurisdictions, cheating is blatantly illegal. You’re better off learning to play poker at an expert level, or learning how to count cards in blackjack.
