RTP the best paying slots, highest paying online casino slots, Return to Player & House Edge Database

In this category we are going to be listing all of the best paying slots from all the major online casino slots providers. So from listing the highest Microgaming slots payback to the loosest NetEnt slots, the top Playtech RTP slots, etc. Finding a loose online slot is very important for your strategy and payouts. Why would you play a slot machine with a low payback of say 88% when you can find hot slots with a return to player of 97% or better?

We have separated this category into individual posts listing the highest rtp slots from the top online slot providers. You can see these RTP posts by scrolling to the bottom of this page or in the below slots RTP lists table.

Even some of the most experienced online casino players don’t truly understand RTP rates. Over the last few years, a big deal has been made of these values in online slot reviews, and many players are getting their facts wrong because of people poorly understanding how RTP rates truly work. Some players may confuse RTP percentages with hit frequency, and others mix them up with low or high variance. Throw other terms in, and everything gets a touch too complicated for many players. We’re here to straighten out this bag of snakes for you. With our guide to RTP, you might finally be able to get to the bottom of RTP rates.

What is RTP?

First and foremost, let’s get the obvious out of the way. What is RTP? RTP stands for Return to Player. It is the theoretical rate indicating how often players are likely to win. Because of this, RTP (when being expressed as a percentage) is often called an RTP rate or return to player rate. You might have seen tRTP or TRTP thrown about the place, too. Don’t worry about, that’s just an unnecessary way of saying theoretical return to player and is mainly found in American sites. We will stick to calling it the international standard, which is simply RTP.

RTP is usually expressed as a percentage and is designed to show how often players will win in the long-term. Obviously, players are looking for as high a percentage as possible here. Almost all developers announce the RTP rates of their slots, and if you can’t find it at an online casino, you can always check out online casino reviews to find the RTP rates of games yourself. You could also calculate the RTP rate of a game, but to do that you need certain information.

To calculate RTP rates, you need to know two things:

  • The total amount paid out by the game to all players
  • The total amount staked by all players

Many of the best casinos will provide you with this information in monthly reports, but if you don’t have access to that, you can do your own mini guesswork. Keeping in mind that the results of one player aren’t likely to generate as accurate an RTP report than having the results from all players at a casino. Playing a free demo game and keeping track of what is wagered and what is paid will give you an RTP rate when you divide the total amount paid by the total amount staked. However, you will need to do this for hundreds if not thousands of spins to get a more accurate picture.

The Specifics of RTP rates

It is important to remember that RTPs involve a percentage of the money paid back to all players over time, not instantly. So, for instance, if you were stake £1 on your favourite slot, and let’s say that it has an RTP rate of 95% (the accepted industry standard nowadays), you would expect to win at least 95p, right? Wrong, and here’s why…

RTP does not work over a single bet, and nor can it be calculated accurately over 2 or 3 bets. You cannot look at RTP in the short term. RTP is calculated over the long term, which means over time, if players wager £1,000, they are likely to end up with £950 being paid back. Suddenly slot RTP rates don’t look so good. Again, that’s in the long-term, though, and anything can happen in the short-term. Here’s why…

In the short-term Player A decides to have a single £1 spin on a slot with an RTP rate of 95%. She wins £500 right there and then. Player B decides to have a crack at the same slot, at the same time, with the same stake. Although the stakes, RTP rate and everything else is identical, he wins nothing. Now, to Player A who won £500 with a single £1 bet, the slot will be viewed as having a far more significant RTP rate than the 95% it is listed at. Player B (who won nothing at all) sees the RTP rate as far less than the 95% listed. As you can see, in the short-term, RTP rates don’t play ball. Yet, if they were to keep playing for a thousand, two thousand, three thousand spins, things would (in theory) balance out, especially if both player’s stakes and wins were taken together in the same calculation.

How do Jackpot Slots Contribute to the RTP rates?

When Player A won £500 on their first spin, that threw the RTP out of whack. So, it is possible for an RTP to go over 100%, but in the long-term, this mainly occurs when a progressive jackpot is won. Should a player win a multi-million-pound progressive jackpot, that is naturally going to mess up the RTP rate. The amount which will have been won by players will often be staggeringly higher than usual, compared to the amount stake. Should an RTP rate rise above 100% because of this, it doesn’t mean a slot is great value for money. The RTP rate will, in all likelihood, level out just as soon as a lengthy period of time passes without a progressive win.

Do House Edges Exist in Slots?

Funnily enough, yes? Let’s stick with the current industry standard which is considered acceptable to most players, 95%. If a slot has an RTP rate of 95%, what does the other 5% constitute? Well, that happens to be the house edge. Most of the time, we don’t look at slot machine games as having a house edge. That is something we usually reserve for blackjack, baccarat, roulette and table poker games. There is a house edge, there, though, and like all games with house edges, it is worth considering and comparing different games to find a game with a low house edge. Unlike table games, though, it is exceptionally difficult to cut down the house edge when playing online slots, even with good, tried and tested betting strategies.

The Bottom Line on RTP Rates

The bottom line is this: if you’re going to be basing decisions on slot playability from the RTP rate alone, you need to think in the long-term. Of course, this requires a reasonable balance to keep playing over a longer period. If you don’t have that, there are other things you can look at which can affect how likely you are to win, and many of them are often confused with RTP rates. Let’s start by looking at Hit Frequencies, as these are often confused with RTP rates.

I Heard About Hit Frequencies, What Are They?

You may have heard the term hit frequencies bandied around before. It is likely that you may even have confused them with RTP rates. You shouldn’t, they form a part of RTP rates but aren’t RTP rates themselves. Slots which display their hit frequencies are far more appealing to players than those which don’t. Why?

Unlike RTP rates, which offer you a theoretical percentage of how much of all wagered stakes are going to be paid out to players in the long-term; hit frequencies promise to tell you how often a winning spin is going to occur. These can be slightly more accurate pieces of information for players looking to play a slot which pays out frequently than RTP rates.

Your average slot machine will have a hit frequency rate of between 9% and 25%. This means that up to a quarter of spins will result in a win. These play a part in determining the RTP rate of course. However, these hit frequencies do not specify whether the wins will be considerable, or petite. They may constitute a 1p win on a £1 bet, or they could amount to a £500 win on a £1 bet. How likely you are to win, and how much you are going to win each time is down to variance. This is another aspect of RTP rates which needs to be considered.

What About Slot Variance and Volatility?

Slot variance or volatility are often confused as the same as RTP rates, too. They aren’t. Just like hit frequencies, they play a part in forming RTP rates. Variance or volatility is the sum of how likely you are to win and how much those wins are going to be worth in relation to your stakes.

Many people would consider a slot machine with an RTP rate of 85% inferior to one with 95%, right? Why would you ever play a slot with a lower RTP rate? Well, that is where variance and volatility come into play. Just because a slot has a low RTP rate, doesn’t mean you can’t win big money on it. In fact, in many cases, it is the other way around.

There are three types of variance in the slot world, low, medium, and high. Each one offers you something rather different.

Low variance slot machines are typically associated with slots that have high RTP rates. In the long-term players will win far more frequently on these games than in medium or high variance slots. Because of this, the game has been set up in a way that it does not pay out big sums very frequently. Sure, you can win on many spins (so it will have high hit frequency rates, too) but the amount you pocket on each win remains small.

As you can imagine, then, high variance slots offer the opposite. These are often slots with low RTP rates, and they do not pay out wins frequently at all as their hit frequencies are low. However, when they do cough up the goods, the winnings tend to be rather spectacular and often very sizable. The trick is having a fat enough balance to sustain periods of continual losses until that big win comes long.

Then there are medium variance slots. As you can imagine, these form most slots out there. They offer you so-so hit frequencies, so-so RTP rates, and so-so prizes. These vanilla slots are what most people choose to play

Another word you may have heard bandied around is volatility. While it certainly sounds snazzier than variance, it essentially amounts to the same thing. Slot volatility is more commonly used to describe how much risk there is with a slot, but the same principle is used as in slot variance. So, low variance slots have low volatility, medium variance slots have medium volatility, and high variance slots are known as being highly volatile. That’s all there is to volatility, really.

You may also have heard the term “high paying slots” thrown about the place. Let’s just clear this one up right now, too. There is no such thing. What one player may consider to be a high-paying slot may be quite different for another. One player may consider a high-paying slot to be one which doesn’t pay frequently, but when it does, it offers jackpots worth thousands of pounds. Another may consider a high-paying slot which pays out frequently, but very little. To each their own. Our advice is to avoid the term “high paying slots” and focus instead on looking for slots with low or high variance/volatility, as per your preference.

So, what is the Slot RTP Rate for Me?

If you are looking for a slot which pays out the big bucks but does so rarely, you’ll need a big balance and any slot machine which is listed as a high variance game and has an RTP rate of around the 85% to 90% mark.

If you are after a slot which provides any wins at all, no matter how small, and frequently, then you don’t need to have as large a balance to play with. You will be looking for any game with an RTP rate of 95% or higher, and one which is advertised as having low variance.

If you’re still not sure and want to play it safe, then go straight down the middle, with a medium variance and volatile slot. The chances are, if you pick a slot at random, this is what you’ll end up with anyway.
