Penny and nickel paytables have fairly low long-term paybacks. Quarter, half and dollar paytables are usually the sweet spot and have the highest long-term paybacks. The paytables at $2 and up may be as good as those at dollars, but sometimes they fall back a bit. There are machines that pay better than others and they're really easy to find. As a general rule, the higher the denomination, the higher the long-term payback. So, nickels usually pay better than pennies, quarters pay better than nickels, dollars better than quarters, etc.

  3. Which Denomination Is Better When Playing Slot Machines Invented

Entire books have been written about how to beat slot machines. Almost all of them are worthless. Slot machines are “negative expectation” games. And most of them have no skill element. Even the ones that do offer odds that make it impossible to be a long-term winner, no matter how skilled you are.

With this in mind, you should play the highest denomination where you feel comfortable betting max. For example, you may be better off betting max coins on a quarter machine than betting one credit.

What’s a “negative expectation” game? It’s a game where the expected value of every be is negative rather than positive. Here’s an overly simplified example:

Suppose you’re playing a slot machine with one prize of $1000. The odds of winning that prize are 1000 to 1. That’s a break-even game. You’ll lose 999 times, but you’ll win once, recouping all your losses. Over the long run, neither you nor the casino stands to win.

But suppose the casino changed the top jackpot for that game from $1000 to $980. Can you see how the casino would then have an edge over the player, mathematically?

That’s how a negative expectation game works. So I’m writing a post about how to beat slot machines, which can’t be beaten in the long run at all. What could I possibly have to say on the subject? You might be surprised. Read on.

1- Understand the Concept of Payback Percentage

In the example I gave above, where the game had 1 in 1000 shot of paying you off at 1000 to 1, the payback percentage was 100%. All the money you put into the machine is eventually paid back. It’s a break even game.

But the payback percentage for the game with a top jackpot of 980 and a 1 in 1000 shot of winning has a payback percentage of less than 100%. The difference between that payback percentage and 100% is the house edge.

The payback percentage is a function of payouts versus the probability of winning those payouts. The game doesn’t have a memory or a cycle. It’s completely random, but the probabilities of the outcomes are known. As a result, in the long run, the payback percentage for a slot machine is going to be under 100%.

Generally, the lower the payback percentage is, the harder it is to walk away from that slot machine a winner. Things like hit frequency matter, too, but payback percentage is the most important metric to consider. And the thing about the slots’ payback percentages is that there’s no way of gauging that number by looking at the machines themselves.

They show the payouts for the various combinations, but the machines don’t include the probabilities of achieving those outcomes. It’s impossible to calculate a payback percentage when you don’t know the probability of winning.

Understanding the concept of payback percentage is the 1st step on the road to beating slot machines.

2- Learn Where You CAN Find Information about a Slot Machine’s Payback Percentage

Even though you can’t get specific with a single machine’s payback percentage, you can find general information about slot machine payouts in general. Magazines like Strictly Slots and books like American Casino Guide publish information about slot machine payback percentages.

This information is normally organized by denomination and location. Generally, the higher the denomination of the game, the better the payback percentage. Also, the busier the location of the casino, the better the payback percentage.

When you’re playing a slot machine with a $1 denomination, the casino can afford to have a higher payback percentage on that machine and still make the same (or higher) profit. And they can afford an even higher payback percentage on a $5 machine.

When you’re stranded at the airport waiting for a plane, or if you’re sitting at a bar waiting for your buddy to finish his karaoke song, you don’t have many options besides playing the slots there in the airport or the bar. They consider you a captive audience.

As a result, they offer lower payback percentages than casinos in competitive locations do. They do this because they’re not feeling the need to be competitive.

If you want to find the slot machines with the highest payback percentages, you should look at the major casinos on the Strip in Las Vegas. You should also look for the games with the higher denominations as best you can. Of course, you can only afford what you can afford, but the penny slots aren’t as cheap as you might think.

It’s useless to try to figure out the casinos’ schemes for where they’re putting the slot machines with the highest payback percentages. At one time, someone wrote a book claiming that the games with the highest payback percentage were always located nearest the walkways. The idea was that the casino wanted to entice players to their games.

That’s no longer true, if it was even true to begin with. As far as I know, that was a tip that came from a single source.

Which Denomination Is Better When Playing Slot Machines

You can try clocking a game to see what kind of payback percentage you’re actually experiencing, but that doesn’t tell you what the payback percentage is over the long run. It’s just what you’ve experience in the short term. The more spins you make, the more accurate it should be, but you’re talking about thousands of spins, not hundreds.

Here’s how to do that if you want to, though:

Start by recording how much money you bought into the machine for. Then track how much each spin of the reels is as a wager. Count how many spins you make. At the end of the session, record how much you lost. Multiply the number of spins by the amount you wagered per spin.

Divide the amount you lost by the total amount you wagered. That’s the percentage of your action that the machine kept.

Subtract that from 100%, and you have the payback percentage for the machine during that session. You can expect that amount to fluctuate wildly if you record multiple sessions.

3- Slow Down

I’ve seen various estimates of how many spins per hour most players make, but the consensus average seems to be 600 spins per hour. The lowest number of spins I was able to get down to was 400 spins per hour, and that was when I was consciously trying to slow down. I’ve watched some gamblers make what I’m sure were at least 800 spins per hour.

Anything you can do to slow down your rate of play increases the probability that you’ll wind up a winner. That’s because the payback percentage is a long term expectation. The more spins you make, the closer you get to the long term. This means that you’ll be that much closer to the expectation—which is negative by the way.

Also, when you’re losing, you can expect to lose less money by making fewer spins per hour. Sometimes this won’t be true in the short term either—after all, this is gambling, and we are talking about random events.

But here’s the predicted loss per hour formula for slot machines: Spins per hour X amount wagered per hour X the house edge = predicted hourly loss

Here’s an example of how that works:

I’m playing a game for $1.25 per spin, and I’m making 400 spins per hour. That’s $500 per hour in action. The game has a payback percentage of 85%, which is the same thing as having a house edge of 15%. My expected loss per hour is $75.

My friend Leyla, though, plays a lot faster on the same machine. She makes 800 spins per hour instead of 400. Her expected loss per hour is $150.

Not only do I have a better probability of going home a winner, but I also have a better probability of losing less money than she does.

4- Consider Playing a Different Game

I’m not bullish on slot machines. The house edge on the slot machines is unknown, but they’re impossible to beat in the long run. And you’re less likely to beat them in the long run, too. That’s because the house edge is so big.

How big’s the difference? Let’s compare some games with some estimated slot machine house edge figures. We’ll assume that you’re playing a “loose” slot machine with a payback percentage of 93%. The house edge on that game is 7%. Blackjack offers a house edge of 1% if you play with perfect basic strategy. Most video poker games offer a house edge of 3% or 4%–less if you find a good pay table. Even craps only has a house edge of 1.41%.


What do your hourly predicted losses look like on those games? At the fastest blackjack tables, you’re probably looking at 200 bets per hour. At $5 per bet, that’s $1000 in action per hour. 1% of that is only an expected loss of $10/hour. At the craps table, you might make 60 bets per hour. At $5 per bet, that’s $300. Your expected loss there is only $4.23.
When

On a video poker machine, you’ll probably see 600 hands per hour. At $1.25 per hand, you’re looking at $750/hour in action. With a 3% house edge, that’s an expected loss of $22.50 per hour.

On that slot machine we talked about, you’re looking at 600 spins per hour at $1.25 per spin minimum. That’s $750 per hour, but your expected loss is 7% of that, or $52.50 per hour.

No game in the casino will take up more of your bankroll in a short period of time when contrasted with slot machines.

5- You Could Also Try Free Slot Machine Games

For the most part, you can’t beat slot machines by only playing the free games online. But some casinos and websites do offer free games with real cash prizes. Winning any money on such a game is a longshot, but it’s still possible.

Usually the ones which offer money are offering free slot machine tournaments, where they have a prize for someone who wins the most money in a week or someone who makes the most spins in a week.

And if you just like the sights and sounds of a slot machine, but you don’t enjoy losing money, you can just play the free games until the cows come home. You can consider that slot machine “beaten” because you didn’t lose any money to it.

6- Learn How to Win a Massive Jackpot on a Table Game Instead

It might seem like the only way to win a massive jackpot at the casino is by playing a slot machine offering such a possibility.

But my favorite gambling writer Michael Bluejay suggests a system where you can win $100,000. The odds are against you, because even when you’re playing the best table games, you’re facing a mathematical edge. But the odds are still better than winning at slot machines.

All you must do is find a table game where you have a maximum bet of $50,000. Then every time you win, put your winnings back into action. Basically, you’ll be doubling the size of your bet repeatedly. If you can win 14 times in a row, you should have $100,000.

Here’s what the progression looks like:

  • $10
  • $20
  • $40
  • $80
  • $160
  • $320
  • $640
  • $1280
  • $2560
  • $5120
  • $10240
  • $20480
  • $40960

After winning 13 bets in a row, you’ll have over $80,000. You don’t have to double the size of your bet this time. Just bet $10,000 and win, and you’ve won $100,000.

Winning at baccarat, craps, blackjack, or roulette 14 times in a row is much likelier than winning a big jackpot on a progressive slot machine.

Most of the time it won’t happen, and if you try this often enough, the house edge will eat up your bankroll. But it’s still a better option than trying to win $100,000 on a slot machine.

7- Play the Most Basic, Boring Slot Machine You Can Find

All the bells and whistles that make modern slot machines so much fun? You pay for all of them in the form of a reduced payback percentage.


If you can find a slot machine with 3 reels and a single pay line that looks like an antique, that’s your best bet at getting a high payback machine game. The bigger and fancier the game is, the worse the payback percentage will be. This means you should avoid games with progressive jackpots. Avoid games with scatter symbols. Avoid games with wild symbols. Avoid games with dozens of paylines.

The top jackpot for most of these basics, boring slot machines will be around 1000 coins, but you’ll be more likely to hit that jackpot than you will to beat a fancier slot machine.

Conclusion

The best way to beat slot machines is by eschewing them in favor of a casino game offering better odds. If you must play slot machines, though, try to keep in mind the tips in this post. Don’t play with money you can’t afford to lose. Be willing to walk away quick if you get lucky. Play as slowly as possible. Stick with games in competitive locations, like casinos. And play the highest denomination games you can afford, even if it means betting fewer coins on fewer paylines.

I went to a party Saturday night, and whenever I go to parties, someone inevitably learns what I do for a living. (I write about gambling.)

This always leads to one of two or three outcomes:

  • I hear a gambling anecdote about my new friend or one of their friends
  • My new friend asks me how to win money gambling. Sometimes they specifically ask how to choose the winning slot machine
  • Both #1 and #2 (this is actually the most common outcome)

I enjoy all these outcomes, by the way, but here’s what happened at this specific party.

A friend of mine started telling me the story of his friend who got fired from Walmart. Later the same day, his newly unemployed friend went to the Choctaw Casino in Durant and won $40,000 playing a slot machine.

My friend’s question to me was, “How do I do that?”

How can *I* choose the winning slot machine?

This post has the answer, but it’s almost certainly not what you’d think.

You Can’t Win by Choosing the Slot Machine With the Highest Payback Percentage.

When I search for this phrase in the most popular search engines, I see pages touting this advice repeatedly:

You have to play the slot machines with the highest payback percentage.

What’s a payback percentage?

It’s also called “return to player” or “RTP.”

A slot machine’s return is the amount of money paid out to a slot machine player compared to the amount of money the player wagered. The RTP gets expressed as a percentage.

If you made $100 in wagers on a slot machine and won $125, you’d have a return of 125%. If you won $90, you’d have a return of 90%.

The difference between the return and the amount you wagered, obviously, is the casino’s profit.

The payback percentage, or return to player (RTP), is a statistical prediction of a slot machine’s return over a massive number of spins. The closer you get to infinity, the closer the game’s results should get to the payback percentage that the game is programmed to have.

Players who win at slot machines win in the short run.

In the long run, all slot machines have a payback percentage of less than 100%. This means that, in the long run, you’ll always lose at slot machines.

How to Calculate the Payback Percentage of a Slot Machine

This theoretical payback percentage can get easily calculated if you have the probabilities behind the machine. It’s just the probability of each win multiplied by the amount of that win, divided by the amount you’d have to play every probability.

If, for example, a slot machine game had 10,000 possible combinations, and if you hit every combination, you’d win 9,000 coins, and the payback percentage would be 90%.

A slot machine doesn’t have to pay out less after a win to “catch up” to its payback percentage. Every spin of the reels on a slot machine is 100% random. The casino makes its profit because of the discrepancy between the odds of winning and the odds that each payout offers.

The payback percentage is not available to the consumer at most casinos. You have no way of calculating it because you have no way of knowing what the probability of getting a specific symbol on a stop is. You can’t calculate the probability of a combination of symbols without that information.

You have the payouts for the prizes, but you don’t know what your probability of winning those prizes is.

Where Does the Casino Put the Slot Machines With the Highest Payback Percentages?

You could play two identical slot machine games sitting right next to each other. One of them might have a payback percentage of 91%, while the other might have a payback percentage of 96%.

You have NO way of telling which machine is better than the other, even if one of those games is paying out more than the other. After all, the payback percentage is a long-term phenomenon.

In the short run, anything can happen.

But even if you DID know the payback percentage for the game, you couldn’t choose the winning slot machine just by choosing the one with the higher payback percentage.

The probability of winning the big jackpot on most machines is at least 1000 to 1.

If you play for two hours, you might make 1,200 spins. You might even win the big jackpot.

But you’ll (usually) have wagered more money on the machine than you won.

You’ll find advice about how to find the slot machines with the highest payback percentages, but most of it is useless. At one time, sure, the slot machines closest to the aisles might have had higher payback percentages.

However, I’ve seen multiple interviews with multiple casino managers who insist that isn’t true.

What About Playing Higher-Denomination Slot Machine Games?

You’ll also see people explain that the payback percentage on the higher-denomination machines is better. This is true as a general rule, but it might or might not be true at the casino where you’re playing. The penny and nickel machines might average 91% at your casino, while the dollar machines might average 95%, but that’s an AVERAGE.

This doesn’t mean that you’ll automatically have a higher payback percentage just because you played a higher-denomination machine.

Even if you did, you’re still fighting a negative expectation game.

Should I Play Slot Machine Games With Higher Volatility?

  • What about volatility?
  • Is a slot machine with a higher volatility more likely to be a winner?
  • Or should I look for the games with lower volatility?

A slot machine’s volatility is its variance from the predicted results. The higher the volatility is on a game, the wider the swings between the wins and losses tend to be.

A game with high volatility pays out less often but can sometimes offer bigger payouts to compensate.

A game with low volatility pays out more often, but those payouts are still low enough to guarantee the casino a profit.

The slot machines at your local casino aren’t labeled according to their volatility, by the way. There’s not a special section for low volatility slots.

You can, though, get an idea for the volatility of a slot machine game via your observations of how often they pay out.

To make your own estimate, you need to count how many spins you make. You also need to count how many of those spins are winners (as opposed to losers).

Divide the number of winning spins by the number of spins you’ve made, and you’ll have the hit ratio for that sample set.

The more spins you’ve made, the more likely the hit ratio you’re seeing is close to the expected ratio.

If you make 500 spins on a game in an hour, and 150 of those spins are winners, the hit ratio for that game is 30%.

If 200 of them were winners, the hit ratio would be 40%.

The game with the 40% hit ratio is the less volatile game.

But keep in mind that an hour’s worth of spins is not representative of the long run. Those are still short-term results. The longer you play, the more accurate your results will get.

You COULD also estimate the slot machine’s actual return over those 500 spins.

Multiply the amount you wagered per spin by the number of spins you made. Then divide how much the game paid out by that amount to get a percentage.

If you put $500 into a $1/spin game, and then you make 500 spins, you’ve wagered $500.

Let’s say you have $400 left after all that wagering. This accounts for all your wins and losses, so the payback percentage — the observed return — is 80%.

That doesn’t mean that this is the theoretical return, but it might be close — especially if it’s a low volatility machine.

Does any of this information help you choose the winning slot machine, though?

Nah. It’s still just dumb luck.

You Can’t Use the Zig-Zag System to Pick a Winning Slot Machine

You might have already heard of this system, but if not, here’s how it’s supposed to work.

The zig-zag system tries to identify slot machines that are about to pay out by looking at the pattern of the symbols on an inactive machine. You’re supposed to look through the slot machines on the casino floor and find one where the winning symbols are in a zig-zag pattern on the front of the machine.

It doesn’t really matter much what the pattern looks like. As long as three winning symbols are present somewhere on the front of the machine, that machine is supposedly “ready” to pay off.

Proponents of the system even suggest that games with two winning symbols showing are getting close to paying off, too.

The idea is that the symbols are coming up more often because the game is getting ready to pay off. Therefore, you’re supposed to sit down and play until those symbols actually do line up on one of the pay lines, and you win.

You can picture these zig-zag symbols in your mind as diagonal lines connecting the symbols on the front of the machine. They might make a V or upside-down V, for example. This is also called a diamond, and it’s supposed to be the best pattern you could ask for.

I can only think of one problem with the zig-zag system.

It doesn’t work.

Understanding why involves understanding something about how a slot machine works. Those spinning reels on the inside of the machine aren’t actually physical reels. They’re controlled by a random number generator. This is especially obvious with video slots, where all the action is entirely animated.

The random number generator (RNG) is a computer program that cycles through thousands of numbers per second. When you click the “spin” button or pull the lever, the computer program stops on a number. That number corresponds to a combination of reel symbols.

Before the reels stop spinning, the RNG has determined the outcome, win or lose.

Every spin of the reels is an independent trial. What’s happened on the previous spin has no effect on your subsequent spins.

What About John Patrick’s Slots Strategies?

My favorite strategies for playing slots come from a book by John Patrick. In it, he outlines several money management techniques which are supposed to help you win at slot machines. All of his strategies are more or less worthless.

Below are some of the concepts he suggests.

The first is the concept of a “naked pull.”

  • A naked pull is a spin of the slot machine reels that results in no winnings at all.
  • He suggests choosing an arbitrary number between 7 and 14 as your “naked pull limit.”

For example, you might choose 7 as your naked pull limit. If you play a slot machine game and get 7 losing spins in a row, you would quit playing that machine and move on to another machine.

This MIGHT help you avoid a low volatility slot machine game, but it doesn’t do much for your probability of winning in the long run. In fact, it does nothing in aid of that.

Having a naked pull limit, though, can be an interesting way to get in some action at multiple slot machines. In that case, you might have a more interesting and fun time playing, which is a type of winning in itself.

Another concept that he suggests is having a session bankroll.

  • In other words, you have a bankroll of how much money you’re willing to gamble with.
  • Let’s say you’re going to Las Vegas for three days and two nights, and you have $600 to gamble with.
  • You might decide to have two slot machine sessions per day — one in the morning and another in the evening.
  • You would then have six sessions planned, and you would divide your bankroll into six-session bankrolls of $100 each.

He combines the idea of a session bankroll with the idea of a loss limit and a win goal. These are just percentages of your bankroll that are going to serve as the end of your session.

For example, you might set a win goal of $50 and a loss limit of $20. If your bankroll slips to $80, you quit for the session. If your bankroll grows to $150, you quit for the session.

Which Denomination Is Better When Playing Slot Machines Made

This, by the way, does nothing to increase your probability of finding a winning machine. It just means you won’t gamble an entire session bankroll.

It also means that sometimes you’ll grind out a winning session.

In the long run, though, you’ll wind up with a loss similar to what you’d expected based on the theoretical payback percentage of the machine. The longer you play, the more likely you are to wind up with those kinds of results.

All his systems combine these concepts to create cleverly named systems, but none of them do anything to get you an advantage at slot machines.

In Fact, No One Can Tell You How to Choose the Winning Slot Machine

You can’t choose a winning slot machine because you can’t predict the future. Slot machines are random. They’re also an example of negative expectation games.

If you play slot machines long enough, you’ll surely lose.

But Here’s the Good News

The expected return on these games is a long-term expectation. This means that not only CAN you win in the short run, but you’re almost guaranteed to have an occasional win in the short run.

In fact, the casino is counting on it.

If you never won, you’d never play.

The trick is to have some idea of what kind of win will satisfy you. When you know what that is, you can play until you hit it and call it a day.

As long as you understand that if you keep playing negative expectation games, you’ll eventually lose all your money, you’ll be okay.

  • Treat slot machine gambling as entertainment.
  • Quit if you get ahead by a significant amount.

Which Denomination Is Better When Playing Slot Machines Dispense

And NEVER spend money on any kind of lame slot machine system that guarantees you the secret to choosing a slot machine that’s ready to pay out.

Conclusion

Slot machines are fun, and choosing a winning slot machine seems like a worthy goal.

Luckily for us, it’s a skill that everyone has in equal amounts. Everyone has a 0% probability of accurately predicting which slot machine is going to be the winning machine.

It’s not like the World Series of Poker, where the players’ skill levels have a huge effect on the outcome.

Sure, you can win at slots.

People do it every day.

It just takes luck and a willingness to lose some money trying to win.
