How To Better Your Odds On Slot Machines

Slot machines with low betting values will help you conserve money and play longer. For example, rather than betting $20 on each spin, you can bet as low as $.01. With only $10, you could last over an hour without hitting any winning combinations. Low-bet slots provide another advantage.

  1. Now, with the advent of computerized slot machines, gaming establishments often program the machines to make hitting large payouts even less likely, so calculating the odds is next to impossible. Set a limit for yourself. Use money that you don't expect to get back, and stay within that limit.
  2. The probability of winning a significant amount of money on slot machines is slim to none. Casinos do not ordinarily disclose the odds of winning at their slot machines, so the slot players cannot be informed of their chances of winning. Believe me the chances of winning big money on the slots are very low.

Slot machines are the most popular games in the casino, although they’re not as popular as they used to be. In some casinos, 80% of the profits are generated by the one-armed bandits. The question on everyone’s mind seems to be the same: how do you win on slot machines?

I wish I had a magical formula I could see you that would ensure you’d walk away from the slots a winner. Unfortunately, I don’t have one. Luckily, neither does anyone else.

Slot machines are entirely random, and they’re programmed to pay out less than the odds of winning, so in the long run, slots are good for nothing more than eating up your gambling bankroll. If you still want to play slots after understanding that, well, good for you. That’s not a problem.

There are some things you can do to improve the odds, though. That’s what I’ll focus on in the rest of this post—actual, practical things you can do to improve your odds of winning on slot machines.

1. Understand the Theoretical Cost of Playing Slot Machines

The savviest gamblers understand the math behind gambling games better than most people. If you grok the way slots work better than other people, you’ll be able to make better informed decisions about what to play and how.

The first concept to understand about slot machines is that each outcome has a probability attached to it. When you multiply those outcomes by the probability of achieving them and add them all up, you get the mathematically expected return for the game.

Here’s an absurd example that illustrates the point well:

You’re playing a slot machine that costs $1 per spin. 50% of the time, you’ll get a combination of symbols that will result in $1 in winnings. The other 50% of the time, you’ll get a combination that results in no winnings at all.

It’s easy to see, given these numbers, how the casino makes a guaranteed profit in the long run from a machine like this.

But to keep things interesting, slot machine designers have multiple combinations with multiple prize amounts. When you do all the math, such a game has a theoretical payback percentage—the percentage of each bet that the game returns in winnings.

These payback percentages vary wildly from game to game, from casino to casino, and from location to location. In competitive areas like the Strip in Las Vegas, slot machines might have a payback percentage of 96% on average. In non-competitive places like the airport, these games might have a payback percentage closer to 75%.

For the purposes of this post, I’m just going to assume that the average slot machine has a payback percentage of 88%. That’s the equivalent of a 12% house edge.

To calculate how much money you can expect to lose playing such a slot machine, you simply multiply the amount of money you’re betting per spin by the number of spins you’re making per hour. Then you multiply that by the house edge, and that’s your hourly expected loss.

So if you’re playing a dollar slot machine and betting $3 per spin, and you’re making 600 spins per hour, you’re putting $1800 per hour into action.

The casino expects to win, on average—in the long run–$216 per hour.

That doesn’t compare favorably with other casino games, by the way. Contrast that with blackjack. Let’s say you’re playing blackjack with perfect basic strategy, and you’re getting in 100 hands per hour. And let’s also say you’re betting $5 per hand. That’s $500 per hour you’re putting into action.

If you’re using perfect basic strategy, the house edge in blackjack is probably 1%. Your expected hourly loss is $5 per hour.

That’s a big difference.

One might almost assume from this that the best way to win at slot machines is to refuse to play them at all.

2. Understand What’s So Attractive about Slot Machines

Most gamblers understand on some level, even if it’s almost unconsciously, that slot machines are a lousy bet.

But they’re still the most popular game in the casino.

How does that happen?

I can guess at some of the reasons slots are so popular. Some of these reasons are easy to understand, too. Remember how I pointed out that you’d only lose $5/hour playing blackjack if you use perfect basic strategy?

Memorizing and implementing basic strategy in blackjack requires work and effort. Some gamblers don’t want to put in any effort toward that sort of thing. They’d prefer to play a game that’s easy to understand and easy to play. And nothing could be easier than mindlessly pressing the spin button on a slot machine.

Also, when you play slot machines, you usually have the opportunity to win a prize of 1000 units or so on a single spin. (A “unit” is the amount you’re betting. If you’re betting a dollar, then a lot of slot machines will have a jackpot of $1000.) Many gamblers like the idea of winning a big prize.

Compare that again to blackjack. You go to all that effort to learn basic strategy, and the biggest prize you can win is 150% of your initial bet. It might be a little higher than that if you get to split your hand or double down. But realistically, most of the time, you’re only going to win a single unit or 2 on a hand of blackjack.

Finally, slot machines are designed for the express purpose of keeping gamblers interested. The companies which design these machines spend countless dollars researching which images, color schemes, and sound effects are going to be most attractive to gamblers. Wheel of Fortune slot machines are no accident. They’re the most popular game for a reason.

If your goal is to play an easy game where you have a shot at a big jackpot, slots might be the right game for you. You just want to decide beforehand if the trade-off is worth it.

3. Improving Your Chances of Winning and Reducing Your Potential Losses Are Both Realistic, Worthy Goals

Let’s talk about how you can make playing slot machines less expensive in the long run.

The first and easiest way to reduce the amount of money you lose playing slots is to slow way down. The biggest factor determining your hourly expected loss is the number of spins you make per hour.

Really fast slots players can make 1200 spins per hour. Average slots players probably get in 600 spins per hour.

But if you go slow, you can probably get down to 300 spins per hour.

In the example I gave earlier, we predicted you’d lose $216 on average per hour. If you were to slow down and only place 300 spins per hour, that number would drop to $108 per hour.

Maybe that doesn’t increase your probability of being a big winner, but if you really want to maximize your probability of winning, you have to switch to a different game entirely—one where you can get an edge. That’s impossible with slots. To get an edge, you need to be able to count cards in blackjack or play expert level poker. There are other ways, too, but they’re an order of magnitude of difference from slot machine play.

You can also reduce your expected losses by playing for less money. There’s a big difference between making 300 spins per hour at $3 per spin and making 300 spins per hour at 75 cents per spin. Your total hourly action drops from $900 per hour to $225 per hour.

With a 12% house edge, that’s a difference of $108/hour versus $27/hour in expected losses.

4. Use Some Practical Tips for Improving Your Chances

That 12% house edge that I keep mentioning is just for illustrative purposes. The truth is, most slot machines have different payout percentages. Your goal should be to find a slot machine with a higher payback percentage rather than a lower payback percentage.

One easy way to compare slot machines is to look at the size of the jackpot. The bigger the top prize is, the lower the payback percentage is. This is especially true when you start looking at progressive slot machine jackpots.

The probability of winning one of those huge $10 million+ jackpots is comparable to winning the lottery, which is to say that the odds are astronomical. Since a portion of the overall payback percentage for that game is attributable to that jackpot, which you’ll probably never win, your practical payback percentage is much lower.

So if you’re choosing between 2 slot machines, choose the one with the smaller jackpot.

Here’s another trick:

Play the highest denomination machine you can afford. The higher the denomination, the better the payback percentage is. That’s a general rule of thumb, but it’s not bad strategy.

And since a lot of lower denomination slot machines push the multiple lines/multiple coins play so hard, you might be betting the same amount per spin anyway. If you’re playing a penny slot machine and betting on 5 lines with 5 coins per line, you’re betting 25 cents per spin.

You’d probably have better odds playing a quarter machine for one payline and one coin per spin.

And it should go without saying that the location where you’re playing has more to do with the payback percentage than almost any other factor.

But I’m not talking about whether the machine is near the restaurant or on the end of a bank of machines or something like that. I’m talking about the location of the casino itself.

The biggest payback percentages on slots in the United States are at the Las Vegas Strip casinos. That’s because that’s the most competitive marketplace there is.

On the other hand, if you’re at the airport in Las Vegas, well… those are the only games in town, right?

They don’t have any real competition, and they know you’re just killing time and playing on a lark, so they don’t need to provide a competitive payback percentage to get your business.

This is also true of bars and gas stations, etc. They’re not competing with other gambling businesses. They’re just looking to make a quick buck while you’re stranded there doing whatever kind of business you need done.

5. Don’t Pay ANY Attention to Silly Slot Machine Systems Being Sold by So-Called Experts

One of the most cringe-worthy gambling books I’ve ever read was John Patrick’s Slots. It’s a collection of 2 or 3 dozen slot machine systems that are supposed to increase your probability of being a winner at slots.

Most of his advice has to do with switching machines when you’re “running cold.” He has a limit for the number of “naked pulls” you’ll accept. (I think it was 7.)

A naked pull is a spin of the reels where you don’t win anything. If you get 7 naked spins in a row, that’s supposed to be a sign that the machine is cold and you should switch to another game.

He also has some general guidelines for session bankrolls. He suggests that you have a win goal and a loss limit for each session, something like 20% of your bankroll for that session. So if you sit down at a game with $100, and you get down to $80, it’s time to quit and switch machines. Same thing if you get up to $120. Quit and switch machines.

Of course, voodoo like this has no effect on your probability of winning or even of walking away a winner. It’s just silly.

You’ll also find people selling books about slots that are supposedly written by “slot machine technicians” who can help you predict when a machine is getting ready to pay out. One of these clues is supposedly the “zig zag” method. The idea is that you find a slot machine where 2 out of 3 winnings symbols are visible at the same time. Such a machine is supposedly close to paying out.

This is just nonsense, too. Every spin of the reels is an independent event, and what happened on previous spins has no bearing on what’s going to happen on subsequent spins.

6. Join the Players’ Club

I have mixed feelings about the players’ club. On one hand, I’m not crazy about sharing my personal information with the casino. They’re going to use that information to advertise to me. I understand why that makes sense for them, but it makes less sense for me.

But from a purely mathematical perspective, it makes sense to join the slots club and always play with the card inserted into the machine. The casino measures how much time you spend on the machines and rewards you with rebates and comps accordingly.

How to better your odds on slot machines jackpot

Don’t buy into the myth that playing slots with the card inserted interferes with your ability to win. That’s just silly. The casinos don’t need to cheat in this way. The games already have a mathematical edge, and the rebates and comps are programmed in such a way that the casino is still hugely profitable.

But even though the comps are much smaller than the amount of money you’re expected to lose, it’s still money that you shouldn’t walk away from. After all, there’s no difference between playing with the card inserted and not inserting the card.

You should milk those comps for everything they’re worth.

Conclusion

How do you win on slot machines?

The short answer is simple enough:

Get lucky.

Slot machine games are entirely random, so there’s no way to get an edge over these games. Anyone who tries to tell you different is hoping you’ll buy something from them. And what they’re selling is worthless.

The best you can do is hope to lower the casino’s edge over you. You can also adjust the way you play so that you minimize the amount of money you lose.

But forget about finding some foolproof way to beat the slot machines. People selling that information are the modern equivalent of snake oil salesmen.

Introduction to High Roller Slots Tricks

This blog continues our journey of winning strategies for slot machine casino gambling. Here, I’ll be explaining to you three easy high roller slots tricks. Now, please understand I’m not trying to turn you into a full-time high-limit slot machine gambler! Not at all!

As I’ll explain, there are some very inexpensive slots winning strategies which can be applied to more than just low limit slots. They can also be rather cheaply used, with only a few bets, on a $1 to $5 denomination high limit slot machine.

The three tricks you should know about involve applying a few of the winning strategies I’ve already discussed, as well as a new slots strategy, winning strategy #6, I’ll be explaining in full momentarily. Here goes!

1st Trick: Use Winning Strategy #1 in a High Limit Slots Area

One interesting pattern I’d noticed at a relatively medium-sized casino had to do with a simple observation. At this local casino, I saw that I would win once when I first sit down, but not win again for some time.

This pattern recognition is a slots strategy I’ve mentioned before, explicitly Winning Strategy 1: Only Win Immediately and my Professor Slots podcast episode #23.

By using this approach, we can take advantage of a common practice found at many casinos, where they provide an initial winning taste.

The first dozen times I visited the high limit slots area at this small, local casino, I found it odd that I would win a jackpot during the first few pushes of the button. But, then, I would spend thousands of dollars without so much as another hit.

I don’t mean I wouldn’t have another taxable jackpot, but that I wouldn’t win anything whatsoever. It just seemed odd. Or, put another way, it was statistically unlikely to be randomly happening so consistently and often, visit after visit after visit.

As an aside, don’t worry too much about all the money I was spending. Unbeknownst to me at the time, each $100 spent these three months earned one more entry for the drawing of a car – which I would end up winning. I tell that story in:

As a second aside, the money I was spending was significant slots winnings from another local casino where I was consistently making quite a profit using Winning Strategy 7, the topic of my next blog article.

2nd Trick: Combining Winning Strategies #1 and #7

Let’s back to the story of what I learned and how I learned it. At the time, I even struck up a conversation with one of the slot operators. In that helpful interview, I asked them when were people winning jackpots and on which machines were they doing it?

This slot attendant helpfully told me about a slots player who had recently gone from one machine to another winning about eight total jackpots in a row in the high limit slots area.

I found this other slots player’s approach very intriguing, to say the least, and have since tried to employ my Winning Strategy 7 alongside playing each machine up to 5 times. By doing so, I’ve found that my annual return for this strategy alone resulted in a 150% profit over my original bankroll.

However, I’d only been using this strategy for four months since this casino opened, and felt I’d need to continue doing it for about a year to be convinced that it wasn’t either temporary or due to having limited data.

Today, I see this as an error on my part, and probably a severe loss of winnings. Winning slots strategies exist, and you can find them yourself – if you can believe your own eyes.

The area most people get stuck on is this: They don’t believe these strategies are possible, and it’s hard to try it yourself they do when you’ve already convinced yourself it’s impossible.

It doesn’t help that most winning strategies are relatively new, and based on the latest casino technologies that started being installed in new casinos since 2012.

Getting down off my usual soapbox, and back on topic, I have found this combination of winning strategies to be the cheapest approach yet to slot machine gambling, while resulting in the highest profit margin.

Using it at my local casino required only $500 per visit and $250 in return on most visits without a taxable jackpot. But then there are the taxable jackpots won, which are more than a few of the typical jackpot winnings on high limit slot machines.

As I’m sure you understand, a single $4,000 taxable jackpot pays for many subsequent visits.

Again, so far, this is all further storytelling about the experiences which resulted in my discovery of Winning Strategy 1 and how to best use it in conjunction with another winning strategy I knew. But, next, I learned a strategy I didn’t already know.

3rd Trick: If a Slot Machine Shows a Win, BET ONCE

By using these known strategies, yet another approach grew out of them. It’s easy, simple, and quite inexpensive. And, it’s completely counter-intuitive to what most slots players will tell you to do. But, because they feel this way is the reason why it works.

Slots players will tell you it is essential to check the machine’s last play. If it shows a winner then, in general, skip that machine. Don’t play it, is the general advice. I say phooey, but with a small caveat I’ll pull from Winning Strategy 1.

My third trick is this: If a slot machine is showing a win, BET ONCE. However, avoid that machine if it’s been played recently.

For this to work, if it is going to work, a slot machine showing a win needs to be idle for a while, and probably hasn’t been idle if its chair is still pulled out. That the chair is even pulled out is a beautiful clue it was used relatively recently.

Why does this work? At some casinos that set up their slot machines to offer an initial taste, the first push of the button of a high limit slot machine will win either a “small” nontaxable jackpot worth several hundred dollars or a more massive taxable jackpot over $1,200.

For example, I happened to be in the casino one Saturday evening, to take care of some tax paperwork having to do with winning a car the night before, and noticed that one of the $100 high limit slot machines was showing a $1,000 win. I didn’t think much of such a small jackpot, as it was not even taxable, but it was something I noticed.

When I went back to the casino the next morning, I noticed that that same machine had the identical winning reel combination showing on it. To me, this indicated that no one had played that machine for just over one day.

At first, I didn’t think much of it. But then, standing there looking at it, I got to thinking about my strategies. And, standing there thinking it through, I learned something.

Previously, my strategy was not to play any slot machine if it showed a win. But, I started to think, what if I was winning at one push of a button on machines that hadn’t been played for some time? Was this perhaps a refinement of a known strategy?

As usual, theory metaphorically in hand, I decided to test it. I walked over to the $100 machine showing the $1,000 win, placed my player’s card along with $100 in the machine, pressed the bet button, and immediately won a $5,000 taxable jackpot.

To date, this is the only time when I’ve won any taxable jackpot on a $100-denomination slot machine. Although, using this strategy at the same casino, shortly later I did win $500 with a single 1-credit bet on another $100 slot machine.

How Long Does a Slot Machine Need to be Idle?

One loose end with using this strategy is the question of how long does a slot machine need to be idle for it to turn into a winning slot machine via this strategy? The honest and straightforward answer is: I don’t know. But, consider my observations.

I’ve found more slot machines are winners with this strategy if I attend the casino on a Saturday morning (especially after a busy Friday night) or mid-afternoon on Sundays.

That’s because these are typically the most extended times when slot machines aren’t played, and being idle for some time matters. But, how long does it need to be inactive, you ask? I’m still piecing together clues about this.

Another clue comes from Eric Rosenthal, from whom I have second-hand information. He knows someone he trusts from within a slots manufacturer who told him that slot machines reset whenever a voucher is printed.

That’s interesting. If true, it means idle means no time at all. So, that information alone may be enough to tell you how long idle is – but I don’t think so.

Why? Because I’ve seen 30 minutes work when an immediate next player did not. Other times, I’ve seen it work after it’s been idle for hours only. Another area of uncertainty is maybe, more like probably, different casinos are set up differently.

But, I have put some effort into trying to figure this out. After some thought, one week later I went back to the casino and took handwritten notes of all the current spin reels showing on all the high limit slot machines at that casino.

Slightly over a day later, I went back to that casino with the intent of executing the usual strategy but brought extra cash with which to push the button once on any high limit slot machine still showing the same reel spin from the previous day.

Unfortunately, that day was a beautiful day in January with moderately high temperatures not seen in months. Somehow, for this reason, the casino and high limit slot machine room were incredibly busy.

I mention this because, when checking the reel spins on each slot machine, I found that ALL slot machines had been played. I then went ahead playing my usual strategy and, to my slight dismay, I didn’t win a single time despite four immediately prior visits where I made 50-60% over the bankroll I’d brought.

What I learned from this confirmation, such as it was, was that it was the wins I had seen when using my unrefined strategy of 5 pulls then stop was occurring on slot machines which had not been played for a while. That is to say, I had been winning on idle slot machines.

So, during busy periods in the high limit slot room which, by the way, isn’t necessarily the same times when the overall casino itself is active, I learned that I shouldn’t use this strategy. Not then, anyway.

All I can say is, where casinos have set up this winning strategy, winning slot machines need to be idle for a while. This bit of information may not seem like much – but it’s something once considered impossible which evidence now suggests isn’t any longer.

And, being the savvy slots enthusiast I know you are, I expect you’ll make the most out of it.

Play High Limit Slot Machines When Appropriate – Carefully!

So, let’s continue to talk about getting the most out of my winning strategies. The whole point of these specific strategies is that they don’t require much money to try out. Not to be too blunt about it, why wouldn’t you try out inexpensive strategies in the high limit slots area?

WikiHow

I suppose I first noticed this myself at Seminole Brighton Casino in Florida in October 2019 and earlier at Foxwoods Casino in Connecticut in April 2018.

Only afterward did I think, while I’m here why don’t I try out the winning strategies I’ve just figured out in the high limit slots area?

Unfortunately, this idea came to me only after I left both places. But, here it is for you. If you have figured out a winning slots strategy that appears to work at a casino, consider trying it in the high limit slots area.

This suggestion is especially valid if the specific slots strategy you’ve found to work outside of the high limit area doesn’t require much bankroll to win. If only a small bankroll is needed, or if you’re willing to risk a larger bankroll if it doesn’t, consider one way to optimize your strategy – by bringing it into the high limit slots area. Carefully, of course.

For those who have read my blog article Seminole Brighton Casino Florida Trip Report, these follow up thoughts for using a working strategy on high limit slots should work quite well there.

However, for those who have read my blog article Easily Win a Little at Slots at Foxwoods Casino Connecticut, I’d caution against this approach there.

As Dr. Mike from the You Can Bet on That podcast very well knows (I was sitting near him at the time), you can win a couple of hundred dollars on a high limit slot machine there within the first few bets.

But, the problem is, you can do the same thing on a low limit slot machines. So, use the winning strategy I described outside of the high limit area to bet less for corresponding winnings. Your profit will be more substantial.

Summary of High Roller Slots Tricks

In review, I’ve pointed out the easy application of two past winning slots strategies, along with a new winning strategy, which would require only a few bets on a high limit slot machine.

From a high level, the three easy high roller slots tricks I’ve outlined are merely pointing out that the winning strategies you worked hard to uncover at the casino you frequent can be leveraged, perhaps even optimized, in the high limit slots area with relatively little risk.

Because, finding that a winning strategy which works is a huge accomplishment, for which you should be proud to have uncovered. But, don’t stop with finding it, even if it was with my help. Your next step is, as always, to work closer to accomplishing your gambling goals.

If your gambling goal is entertainment, as with more slots enthusiasts, then getting a W-2G for having won a taxable jackpot would be exciting. I know my first W-2G was very exciting and, quite honestly, you never really get tired of winning them.

If your gambling goal is earning comps, then you’ll undoubtedly earn players clubs point by making bets on high limit slot machines. But, more importantly, some or all of winnings received in the high limit slots area can be spent on low limit slots.

Finally, is winning take-home money your gambling goal? Well, you’ll earn that money with little cash spent. If, as always, the casino you’re at has been set up by their operator such that one or more of these approaches will work.
