Suppose you have a slot machine with three reels with ten symbols on each, and it only pays out when three cherries hit. The odds of winning that jackpot, as we determined earlier, is 1/1000. If we set the jackpot as $900, and charge $1 per bet, the payout percentage for that game will be 90%, or $900/$1000. In the typical slot machines the top jackpot for every reel would correspond to just one virtual stop. What this means is that the chance of the player hitting the jackpot in one reel is 1 to 64. If all the reels in the machine are set up that way, then the chance of hitting the jackpot symbol in all the 3 reels is 262,144. Jan 02, 2020 The slot machine above would return 97.5% to players in the long run. However, we rarely know the odds of slot machines. We do know the paytable - how much each winning combination pays to players - but we have no idea of the probability of getting that winning combination.

Slots odds are the probabilities of getting a winning combination on the reels. They depend on the type of slot machine you play. Originally the odds were very easy to calculate as the only thing the players had to consider were the number of reels and the symbols used on each of the reels. As a result, the 3-reel slot machines are traditionally believed to be better for player's winning chances, and thus the more reels and symbols on them, the lower a player's advantage.

How to Calculate Odds

The odds of getting any combination on the slot reels are easy to calculate if you know the number of symbols used on each reel. Let's take a closer look at the odds and consider an example:

If you have to make a line of 3 diamonds on one payline to win the jackpot, it is most likely that each reel has only one diamond symbol on it. If the machine is a 3-reel one and there are 20 symbols on the reels, the chances of hitting this combination are:

Possible combinations on the reels: 20 x 20 x 20 = 8000. The odds of getting this combination are 1 in 8000. For a 5-reel slot machine the chances are even less: 20 x 20 x 20 x 20 x 20 = 1/ 3,200,000 (1 in 3,200,000). The slots probabilities are usually shown as a percentage, so for 3-reel and 5-reel slot machine with 20 symbols on each reel we have these probabilities:

However, the number of symbols on the reels can differ from machine to machine, and that is why the slots odds are different. Here we look at some more examples of slot machines containing 3 and 5 reels each with different number of symbols on them - for these examples: 20, 22 and 25.

Slots Payback Percentages

The slots payback or return is the amount of money the slot machine pays out as winnings, against the total number of credits wagered by players. The payback is always shown in percentage.

The main idea behind counting the odds in slot machines lies in understanding how the machine pays out money. Unlike what many people believe, not everything is random in a slot machine. Slots are programmed to pay out a certain percent of the money put in with each play.

For example, one machine may pay back 80% of bets while another one may pay back 91% and even 100%. This means that for every dollar put in the machine the casino takes 9 cents and pays out 91 cents. But it does not do it for every dollar put in, it just pays out explosively and this is what makes the game so great.

You must remember that there are two basic types of slot machines. These are:

• Loose slots are slot machines that are programmed to return 82-98% of the wagered money, or even more if you play slots online. As a rule, high-denomination slots pay out more than those offering, for example, $0.05 or $0.25 bets. For more about typical paybacks on different slot machines please read the strategies page.
• Tight slots are machines that pay out less than 80% and sometimes down to 50% of the wagered money. To avoid playing at these slot machines try not to gamble in motels, airports, bars, gas stations, etc. The payback percentages vary from casino to casino and that is why it may be difficult to find the best machine in the gambling hall.

As you understand, one of the best slots tips on how to win at slots is always to look for the loose machines. It can be easy if the gambling hall shares this information with the visitors. In any case you can gamble on the Internet as most online casinos provide the statistic data about their slots games. So, when choosing one of the casinos recommended by SlotsDoc.com you can expect such paybacks:

Slot machines are the most exciting casino games in the world. The combination of simplicity and huge jackpots - along with plenty of psychological factors designed in the game (best explained in Addiction by Design: Machine Gambling in Las Vegas by Natasha Dow Schull) ensure that Americans keep pouring billions of dollars a year into slots. The downside for customers? You'll lose by a wide margin in the long run, and in general the bigger the jackpot, the more of an edge the slot machine has over you.

You can increase your chances in the long run, though, by choosing the right games at the right casinos -- it's not unheard of that you will lose five times the amount on average that you would have lost if you chose the best slot machines and played at the best online casinos.

The intention of this slot machine guide is to explain everything you need to know about slot machines in order to minimize your losses and give yourself the best chances to win money. If you're just looking for a high-quality, reliable slots online casino to play at, here are my top recommendations:

How Real-Money Slots Work - The Basics

A slot machine has no feelings. The amount of winnings it pays are dictated by the EPROM chip and the random number generator ('RNG') inside the machine. It doesn't consider whether someone has recently won or lost -- every spin of the reels is random.

It's possible to influence your chances of winning at slots. When you press Spin, the RNG generates a random number (between one and a billion, for example) for each reel of the machine. Every number represents one of the symbols (the more numbers represent a symbol, the more it is 'weighted' in the machine).

The EPROM chip then determines whether you've won with the combination of symbols or not; the more winning combinations there are, and the more the player wins per winning combination, the higher the odds of winning and the payback of the machine.

Suggesting you have all the information available, calculating your chances of winning at slots is simple: multiply the probability of each outcome with what those outcomes pay, and then sum the results. It's always under 100% (otherwise casinos would make no profit) and often near 90% (casinos make a lot of money from slots).

Here's an example of an imaginary slot machine (let's call it King of Cats) with three winning combinations -- a real-life slot machine works the same way, but likely with more ways of winning at slots:

The slot machine above would return 97.5% to players in the long run. However, we rarely know the odds of slot machines. We do know the paytable - how much each winning combination pays to players - but we have no idea of the probability of getting that winning combination.

To calculate the probability of a winning combination, we need to know is how many stops there are for each symbol. For example, in the machine above there could be 45 stops and one of them would be a Lion symbol. By calculating (1/45)*(1/45)*(1/45) we get 0.001%, or the probability of hitting three Lion symbols in a row.

In real world, those symbols would have been weighed differently so that they're more likely to come on the first two reels and much less likely to come on the last reel, resulting in a near-miss situation.

I advise you not to play at all because slot machine odds are never good, but if you're going to play anyway, here's how you can find the slot machines that likely have better odds than others.

Why We Lose At Slots

We lose at slot machines because they're set to give back less than they take on average. It's impossible to play slot machines better; you can just press spin and hope for the best. With that said, though, you can improve your odds of winning at slot machines greatly by making good decisions before playing and having a good strategy when entering a casino - more about that lower on this page.

Generally, the more decisions you can make in a casino game, the lower the house edge is (with optimal play). Since there's almost no room for decisions when playing slots machines - again, your only decision is to press spin - the house edge is high at slots when compared to other popular casino games. And since you play slot machines for real money so fast (400-800 spins an hour), you lose more at slots than at any other casino game. (Read how slots work to understand them better.)

Like most casino games, a slot machine is a game of independent trials (the previous game has no influence on the next game). Your chances of winning with each spin are the same regardless of whether you've lost or won. So, there's absolutely no room for in-play slot machine strategy.

How Much Do Slot Machines Pay Back?

A slot machine's payback percentage could be anywhere from 75% to almost 100%, but of course, always lower than 100% (otherwise, the casino would make no profit). You can calculate a casino game's house edge by subtracting its payback percentage from 100% - this is how much the casino makes per bet in the long run. For example, with a 5% house edge, casinos make $5 per every $100 bet.

Calculating a slot machine's payback percentage is easy if you have all the information available: multiply the probability of each outcome with what they pay, and the sum is how much the slot machine returns in the long run, also known as its 'payback.'

But most of the time we don't have that information. We're in the dark -- sure, casinos can claim certain payback or payout percentages but how do we know they're truthful? Some online casinos get their payouts reviewed by private auditors, but how do we know if the auditors are honest?

It's a different situation with games like blackjack or roulette; in both cases we can calculate the house edge because the rules are known. If you care enough to make the calculations (and you should), you'll know exactly how much you stand to lose or win in the long run.

You could argue that casinos make so much money from slot machines that they have no reason to cheat. I agree, but you can still get a raw deal even if they are honest (setting a low payback percentage is not cheating). I want to have an idea of what kind of a return I get for my money regardless of the honesty of the casino. (See how to pick slot machines to find the best slots to play.)

Not only do casinos keep slot machine players in the dark about payback percentages, they have also weighed slot machine reels differently, resulting in as many near-miss moments as possible, which encourage future play. The first reel is the likeliest to hit something, the second reel is less likely to hit and the third reel is even less likely to hit.

NOTE: Some casinos are tested by auditors that publish monthly payout percentages for everyone to see online - now, 'payout' is different from 'payback.' The actual money that the casino has returned to players through their games is 'payouts' and the theoretical money that the slot machines are set to return is 'payback.' Payouts can be influenced by huge jackpot wins, for example, in which case a month's payout would look much better than the games have been set to pay back.

How You Can Win More

Here's the truth: the best thing you can do is to stay far away from slot machines (and stay clear from myths). Losing less is winning more and you can lose the least by never playing slots, even if you knew how to play slot machines the optimal way.

But you came here to learn how to play slots for real money, so I have to assume that you will play them at some point. Good news: you can win more (or, in fact, lose less) by playing the right slot machines at the right casinos.

The main consideration is always payback but you should also pay attention to casino comps and other benefits (such as cashback) that come along with playing at casinos.

Why to Play Slots

Some of you may wonder why to play slot machines at all. Exactly. They're a terrible investment -- think of a machine that you put $1 in and receive $0.95 back. That is basically a slot machine, except for all the sounds and animations, and of course a chance to win a lot of money, perhaps even millions of dollars.

Typical Slot Machine Odds Jackpots

The odds are heavily against you winning that money though. Meanwhile, in the long run, the casino takes your dollar bills and gives you back less. So if you agree to participate in this weird transaction, the least you can do is to find the casinos and slot machines that give you back the most money.

How to Find the Best Casino Slots to Play

Typical Slot Machine Odds Against

If you're going to play in Las Vegas or some other popular gambling destination, take a look at this survey. It'll give you a good idea of how the location of the casino affects the general payback percentage of its slot machines; the best Las Vegas casinos are located mainly in North Las Vegas, not on the Strip. You can use the same logic in other places where there are many casinos around, although if you're 'stuck' with only a few, I'm not sure if location makes much of a difference.

After selecting a casino that potentially has a high payback percentage on average, an important part of a good slot machine strategy is to immediately join the casino's Slot Club (could be called 'Player's Club' as well). Contrary to popular myths, Slot Club members have the same house edge in their games as other players; the difference is, casinos can track Slot Club members (you have to insert a Club membership card to the slot machine when you play) and it helps them to give you comps when you deserve them (otherwise you may miss-out on them). You'll likely receive something extra just for signing up - free money to play with or a free drink, for example.

Casino Slot Machines Odds

Additionally, most casinos give Slot Club members cashback (0.5% per bet, for example) and that is almost like playing against less house edge, although not literally. You don't win more likely but you receive a portion of your bets back.

Now, look around the casino. I bet you feel the temptation to head over to the flashiest slot machines with the biggest jackpots. That's what most slot players do and it's exactly the opposite of the best way to play slots. Unless your only goal is to win a million dollars (regardless of how unrealistic it is), playing progressive jackpot slots is the worst slot machine strategy you can choose. Many make that mistake and it's no wonder why US casinos get 70% of their revenues from slot machines.

Odds in Progressive Jackpot Slots

The only way you can win a million dollars playing slots is to play slot machines with progressive jackpots, however, you get even worse odds to win than you would get if you played flat-top slots.

The odds of winning a jackpot are usually way better on the first reel of the machine than on the last one. The casino wants to create as many 'near-miss' moments as possible -- it is a psychological trick, designed to make the player want to to play more.

It's easy to see why near-misses work: if you're one symbol away from winning a jackpot, it'll leave you with a different feeling than if the jackpot wasn't close at all.

In reality, it only seemed to be close.

In Nevada, the regulations state that one stop on the reel can't be weighted more than six times the stops before and after it (many have adopted this rule).

Progressive slot machine odds could be weighed like above; the first reel hits a jackpot symbol once out of five times while the third reel only hits once out of 13 times, often resulting in mentioned 'near-miss' situations.

But that was a simplified example. Hitting a progressive jackpot usually has more symbols, of course, and way worse odds. The chances of winning the biggest of them all, Megabucks, are somewhere in the 1:50,000,000, according to John Robinson at Casino City Times.

Slot Machines Odds Of Winning

Progressive slot machine odds are worse than flat-top machines (the ones without a progressive jackpot) -- this is because a part of the bet goes to the jackpot while the casino takes its own cut. Unless the size of the jackpot is huge - in which case playing jackpot slots could be worth it - it always makes sense to choose a simple fixed jackpot slot machine.

So which slot machine types are best for you?

The simplest slot machines, also known as 'straight' or 'flat-top' slots, are your best choice financially. No, you can't win a million dollars playing those machines, and yes, they're less flashy than other slots, but they're the best slot games to play at a casino. For every dollar you bet, you may have to lose 10 cents more to flashier machines with progressive jackpots - that's a huge difference in the long run.

So now that you've chosen a simple machine, let's think about your betting strategy for slot machines (I'm not referring to progression betting systems; they don't work):

Video Slot Machine Odds

• Choose the highest denomination. The higher the denomination, the lower the house edge. For example, nickel slots have a higher house edge than dollar slots.
• Bet the maximum amount of coins. There's usually an incentive to bet maximum coins. For example, the jackpot becomes bigger relative to the bet, giving you a better return from the machine (odds stay the same but payout increases relatively more than bet size).
• Bet slowly. Not because pressing the Spin button fast or slow would impact your odds of winning at slot machines, but because it's a viable slot machine strategy because you have more time to play with your money and the longer you stay at a casino, the more comps you'll probably receive.
