Online Slots RTP: A Full Guide

If you're new to the online casino and gambling world, you may have heard the term high RTP slots bandied around new slot sites and wondered “what does RTP stand for?” And if you're an experienced gambler or an online slot aficionado, then you know how important an online slots RTP is in deciding whether you're going to play on it or not.

Whether you know what it means or not, the team here at are here to fill you in on exactly what you need to know about RTP and the best slots to play, how it works in relation to online slot games, whether variance affects it, the top RTP slots games and even more.

What Does RTP Mean?

What does RTP actually mean in the context of casino games? It stands for ‘Return To Player'. This percentage is basically the reverse of the ‘house edge' and tells you as a slot player the average the video slot machine will pay you back over a large number of spins. For example, let's take an online slot machine that has an RTP of 98% (a house edge of 2%). Using this figure, we know that over an extended period of time, for every £100 you spend on the machine, you'll get back £98. A general rule of thumb is that the best paying slots have an RTP of 90% +.

An important thing to realise when talking about returns in regard to slots with the best odds is that this percentage is worked out over an absolutely huge number of spins – we're talking in the millions. If you're playing a comparatively ‘short' session compared to this – a few hundred or maybe even a few thousand spins, then anything goes and you should expect any kind of return. This is one of the things that makes online slot games exciting, the unpredictability of whether you're going to hit a big win or not. If these percentages were fixed for every 100 spins… then ultimately you'd always make a loss!

The Maths Behind RTP

Calculating and configuring the return on online slot machines is incredibly complicated. If the online slot machine has extra features – such as bonus rounds, jackpot mechanics and a huge number of pay lines – then these add to the complex process. Any online slot developers need to include these things whilst making sure the machine itself sticks to the correct RTP.

On the whole, an online slot game will be programmed to give back a certain percentage of the total amount of money that is put into it. The actual allocation of return varies between slots – More on that in a sec – but if an online slot has a nive high RTP of 97%, then it will return 97% of all the money put into it if played for an infinite amount of spins.

Online Slot Variance vs Return To Player

A common mistake players make is confusing the variance of a slot machine with the return to player, or the other way around, These concepts are very closely related, but they aren't the same thing. We explained what RTP is above, so we'll take a closer look at online slot variance and how it affects you as a player.

When we talk about variance, we're talking about how the RTP is understood. Slots with lower variance slots are programmed so that you'll have smaller payouts more often, helping you to stay in the game and play more spins on that online slot. Slots with higher variance will tie up most of the returns percentage in the extra bonus features, allowing you to have a chance at some incredible wins. It's not all sunshine and rainbows though – to compensate for these huge wins, these slots often pay out smaller amounts much less often.

We aren't saying that all of the highest payout slots you can find at online casinos are the best bang for your buck. In fact, in general, a higher RTP online slot can be seen as the top slot online to play on. But if you choose to play on a high variance game, it can take a while before you actually get close that particular slots true RTP.

RTP Myths

Now that we've cleared up what RTP actually is, let's dive into some common myths that about them and then get into the highest paying slot machines and best slots for winning. Since their creation, players have developed their very own ideas about how online slot machines return winnings to players, and below are the most common ones:

Online casinos actually manipulate the RTP of slots into their favour

This is totally false. Most online casinos themselves don't actually own the slots they offer – the software developers do. These casinos are just renting the online slots from the creators, with the games themselves running from and stored on the developers' servers. This means these casinos can't access the back end of the online slot top change any of the foundational settings (such as RTP). There are games out there which have varying levels of returns percentage, but a casino can't just change a machines RTP on the go.

The RTP of the highest RTP slots doesn't matter for a single session of playing

This can be seen as both true and false. in a single online slot gaming session pretty much anything can happen – you could lose or have a huge win. Whilst some people view a high return as a technique of how to win at slot machines, You're actually very unlikely to realise the true RTP of a slot machine in a single gaming session. Knowing this, some players can see the return of an online slot as totally irrelevant. But in general playing on an online slot game with higher RTP is seen as better – so an online slot with 96% return percentage is seen as better to play on that a 90% return online slot.
