What Is The Percentage Of Winning On Slot Machines

The winning patterns on slot machines – the amounts they pay and the frequencies of those payouts – are carefully selected to yield a certain fraction of the money played to the 'house' (the operator of the slot machine) while returning the rest to the players during play.

Slot machine odds used to be easy to calculate. When you’re dealing with three reels, ten symbols on each reel, and a limited pay table, then it’s just a simple math problem. But the rise of electromechanical slot machines and (later) video slots added some complexity to the situation.

How Probability Works

Probability has two meanings. One is the likelihood of whether or not something will happen. The other is the branch of mathematics that calculates that likelihood. To understand the odds as they relate to slot machines (or any other gambling game), you have to understand the basic math behind probability.

Don’t worry though. The math isn’t hard. Probability involves addition, subtraction, multiplication, and division, all of which you learned in middle school.

The first principle of probability is that every event has a probability of between 0 and 1. If something has no chance of ever happening, then its probability is 0. If something will always happen, no matter what, then its probability is 1.

Probability is, therefore, always a fraction. It can be expressed in multiple ways, as a decimal, as a fraction, as a percentage, and as odds.

A simple example is a coin flip. The probability of getting heads when you flip a coin is 50%. That’s common sense, but how is it determined mathematically?

You simply take the total number of possible outcomes, and divide the outcome you’re trying to determine the probability of it by that number. There are two possibilities when flipping a coin, heads or tails, but only one of them is heads. That’s 1 divided by 2, which can be expressed as ½, 50%, 0.5, or 1 to 1 odds.

Odds are expressed as the number of ways something won’t happen versus the number of ways that something will happen. For example, if you’re rolling a single six-sided die, and you want to know the odds of rolling a six, you’re looking at 5 to 1 odds. There are five ways to roll something other than a six, and only one way of rolling a six.

When you want to determine the probability of multiple things happening, you use addition or multiplication, depending on whether you want to determine whether one OR the other event will occur, or whether you want to determine whether one event AND the other event will occur.

If you’re looking at an “OR” question, you add the probabilities together. If you’re looking at an “AND” question, you multiply the probabilities by each other.

So if you want to know what the probability of rolling two dice and having one or the other come up with a six, you add the probabilities together. 1/6 + 1/6 = 2/6, which is rounded down to 1/3.

If you want to know the probability of rolling two dice and having BOTH of them come up six, you multiply the probabilities. 1/6 X 1/6 = 1/36.

How Slot Machine Odds USED to Work

Early slot machines were mechanical devices. They had three metal reels that had ten possible stops each.

To calculate the odds of a single symbol appearing on a reel, you just divide the one symbol by the total number of potential outcomes. So if you had one cherry on a reel, your odds of hitting that cherry were 1/10, or 10%.

To calculate the odds of getting three cherries, you multiple 1/10 X 1/10 X 1/10 and get 1/1000, or 0.1%.

If the odds of hitting that symbol are the same as all the others, then you have 10 possible jackpots you can win, which means that your chances of winning SOMETHING are 10/1000, which is 1%.

What Is The Percentage Of Winning On Slot Machines Every Time

Most people wouldn’t play a slot machine that lost 99 times out of 100, though, so slot machine designers added additional, smaller prizes for getting two symbols out of three for certain symbols. And as long as they paid out less in prizes than the odds of hitting those jackpots, then those slots are guaranteed to make a profit in the long run.

For example, if a prize for hitting three cherries was $1000, you’d be playing a break-even game, but if the prize were $750, it’s easy to see how the casino would be guaranteed a profit. The difference between the odds of winning and the payout odds is where the casino makes its money.

How Slot Machines Work Now

Modern slot machines use a computer program called a random number generator to determine the outcomes of the various spins of the reels. This creates an imaginary reel with a number of symbols limited only by the program in question.

A mechanical slot machine with 256 symbols per reel would be huge, too large to play, much less to build. But a computer can create an imaginary reel with 256 symbols per reel and take up no more space than an iPod Shuffle.

To make things even more interesting and entertaining, slot machine designers can program different probabilities for each symbol to come up. Most symbols might come up once every 256 spins, but others might come up twice as often, while still others might only come up half as often.

This enables slot machine designers and casinos to offer slot machine games with far larger jackpots than they were able to when they were limited by mechanical reels. And they’re able to offer these large jackpots and still generate a healthy profit.

How Does This Relate to Payback Percentages?

The payback percentage is the amount of money that the slot machine is designed to pay out over an enormous number of spins. This number is almost always less than 100%. The difference between 100% and the payback percentage is the house edge, and that’s where the casino makes its profits.

A simple example can help illustrate how this works. 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. Of course, no one would play a slots game which only paid out once in every 1000 spins, which is why there are various smaller payouts programmed in.

There’s no way to tell what the payback percentage on a particular game is unless you have access to the par sheet for that machine. Casino management has that information, but players never have access to that info.

The best slot machine odds are almost always found in real casinos. If you see slot machines in an airport or a bar, be aware that the payback percentages on those games is much lower than you’ll see in a real casino.

What Are The Chances Of Winning Big On Slot Machines

Games offering progressive jackpots and bonus rounds are popular with players, but slots with the best payout rates or payback percentages are considered among the top prizes in the world of gambling. After all, even a couple of extra percentage points can make a major difference when calculating the profitability of an individual slot.

This article examines the definition of “payout percentage” and explains where to find the most generous slot games. While it won’t improve your actual chances of winning, the knowledge that you’re playing a more liberal slot machine should at least boost your confidence.

What Is a Payback Percentage?

The payback percentage—also known as the payout percentage or return to player—is the amount of money deposited into a slot machine that is eventually paid back to the customer. This percentage is not determined in weeks or months, but rather over the life of the machine.

For example, let’s say that $100,000 is inserted into a slot machine with a 92% payout percentage. According to the RTP (“return to player”), the slot should pay back $92,000 of the wager in the form of wins, while keeping the other $8,000 in profit. Keep in mind, however, that the true payout of a slot machine may take millions of spin to determine.

When a machine’s software is written at the factory, this is when the payback percentage is set in accordance with local laws. For example, slots in New Jersey must be set to pay back a minimum of 83%, while games in Nevada have a lower limit of 75%. On average, the payout percentage for most slots ranges from 82% to 98%.

Slots with a high RTP are known as “loose slots,” while their stingy counterparts are referred to as “tight slots.” Since these figures are rarely reported, it’s difficult for a player to accurately determine whether the machine they’re playing is loose or tight.
In previous years, the RTP was set at the factory and any additional manipulation by the casino required the software to be switched. Thanks to advances in computer technology, many casinos can now remotely manipulate the odds and payout, although they must wait until the machine has been vacant for at least four minutes (no mid-game manipulations).

How to Find the Highest Paying Slot Machine

Casinos love to promote their slots as being loose or easy to win slot machines, but they’re tight-lipped when it comes to actually identifying the machines. In most cases, a few loosest slots are sprinkled into rows of tight machines, which still give the casino the opportunity to brag about all the loose slots they offer.

Unless you happen to have a casino manager in your back pocket, it’s going to be difficult to determine a game’s true payback percentage. Gambling forums and chat rooms are often filled with people who claim to know the RTP for various machines, but you should only trust those sources with impeccable credentials. Otherwise, it’s probably an educated guess or outright lie.

Games with Top Payback / Payout Percentages

While it may be disappointing to hear, a so-called list of loose slot machines is useless. There are a couple of reasons for this, which I will explain below.

Varies by Machine – Just because one slot machine from a certain series pays back 96%, another identical machine may only pay back 89%. These differences aren’t listed by the casino, so the player is left to play a guessing game.

Location – Even if you somehow learn that the fifth machine on the fourth row pays back 97%, it’s only a matter of time before the casino changes its physical location.

When searching for the best RTP, the best strategy is to look at the minimum paybacks allowed by law. Any law-abiding casino cannot go below this number, which at least gives you a worst case scenario for the rate of return. Unfortunately, not all states have a minimum, and establishments aren’t always required to disclose their payback setting (especially Indian casinos, who regulate themselves). Still, I’ve included what meager information I could gather.

  • Arizona – 83% minimum payback
  • Delaware – Their video lottery terminals must pay between 87% and 95%.
  • Kansas – 87% minimum (80% at Indian casinos)
  • Louisiana – Casino slots must pay no less than 80% and no more than 99.9%. The minimum return at locations other than casinos is 80%, with a maximum of 94%.
  • Maine – 89% minimum payback
  • Maryland – 87% minimum payout
  • Minnesota – RTP must be between 80% and 95%.
  • Nevada – 75% minimum RTP
  • New Jersey – 83% minimum payback
  • New Mexico – Between 80% and 96%, although Indian casinos have a required minimum of 80%.
  • North Carolina – Payout must fall between 83% and 98%.
  • North Dakota – Slots carry a minimum return of 80%.
  • West Virginia – Carries of minimum requirement of between 80% and 95%.
  • Wisconsin – Minimum return of 80%.

What Are The Chances Of Winning On Slot Machines

Slots with the best payback percentage are highly coveted in the world of gambling, so expect a feeding frenzy whenever a game’s true RTP becomes known. This doesn’t happen very often, though, as casinos love to move machines around to keep savvy patrons guessing. Ultimately, your best chance comes from reading the rules, understanding the pay table, and keeping your expectations in check. Once you meet these requirements, you’re a lot more likely to walk away from the casino with a smile on your face.
