What Is RTP In Slots?

For those familiar with online slots and the terminology that surrounds the iGaming industry, RTP is best described as a reverse house edge. Ultimately, it’s the mathematical advantage a casino has during each game round, expressed as a percentage.

However, we understand that newer players may be somewhat confused by certain terms and phrases they come across when gambling online. Therefore, we’ll aim to clarify precisely what the term RTP means.

During the development stage, studios run simulated spins to test how a game’s math model works, and we’re talking millions, if not billions of them. The reason being is that they’re looking to see how much money is paid during this time and whether it correlates with the game’s RTP.

For example, let’s say a slot has a 96% RTP. Theoretically, this means that if you wager $100, you can expect to see a $96 return.

However, what you must bear in mind is that because the RTP is calculated over such a larger number of spins, you will see deviations during the short term – you could end up with solid returns or you could just as easily lose your entire bankroll.

Ultimately, if you play through enough spins, your returns will begin to more closely reflect the slots listed Return to Player percentage – remember, though, this is from a theoretical standpoint.

How To Find The RTP In An Online Slot

Regulators require online casino games to display their respective RTP rates for the purposes of transparency.

Check the game’s paytable

You’ll usually be able to locate this figure within the slot’s paytable or game information panel – clicking on the help button or menu usually reveals the necessary statistical information.

Beware of varying RTP levels

However, certain providers release titles with varying RTP levels, which allows operators to adjust backend settings and tip the scales in their favour. So, just because you see a slot advertised with a certain RTP, it doesn’t necessarily mean all casinos have it set to the same level.

For more information, we recommend that you check out our in-depth RTP guide – it explains this topic in much greater detail.

RTP And Volatility

Earlier, we touched upon the topic of an online slot’s math model. This is a term used to describe a combination of elements including RTP, volatility and hit frequency. Whilst you’re unlikely to notice much of a difference between one slot with a 98% RTP and another with 94% in the short term, you’re much more likely to perceive how a title’s volatility governs the underlying gameplay. To put it concisely, RTP gives you an indication of your theoretical returns, whilst volatility dictates how those winnings are paid.

Volatility, also referred to as variance, determines the behaviour of a game in terms of risk versus reward. Games are often listed as either low, medium or high volatility slots, although certain providers push these boundaries even further – Nolimit City, for example, has launched several releases rated ‘extreme’.

In essence, volatility gives you a rough indication of how often winnings are awarded along with their typical value.

slotsia High volatility slots

High volatility slots tend to favour delivering larger wins in shorter periods, but you’ll likely see fewer less valuable payouts. These types of slots may not be best suited to casual players or those of you playing with a limited bankroll as they tend to involve much more risk. However, they are often some of the highest RTP slots available.

slotsia Low volatility slots

Conversely, low volatility slots usually award payouts at a much more consistent rate. They’re a good choice if you’re looking to keep your bankroll ticking over as you go in search of special in-game bonuses and features, but they often don’t have the capability to produce huge hits like their high variance counterparts.

List Of The Highest Rtp Slots

So, now that you have a complete understanding of what the terminology means, the question is: what are the highest RTP slots? Well, to answer that we’ve handpicked 10 of the best RTP slots currently available and we’ve outlined what you can expect from them below.

Jackpot Slots RTP

Jackpot slots differ slightly from regular slots because a portion of the RTP is reserved for the awarding of their jackpot prizes. That’s why it’s often the case that the advertised RTP rates are typically lower than online slots with no jackpot.

In order to offer a progressive jackpot, a game must collect a portion of each wager to build a prize pool. Each time you hit the spin button, the majority of the stake goes towards the regular prize pot, whilst a small percentage is held back for the jackpot pool.

Land-Based Vs Online Slots RTP

If you’re the type of player who also enjoys visiting your local casino to play slots, you’ll want to be aware of how wildly their RTP rates can vary from what you’d usually expect online.

slotsia Land-based RTP

Land-based slots can be set to return anything between 70% – 90%, with very few ever exceeding 92%, so online casino games often offer a significantly higher RTP rate.

slotsia Online slots RTP

Online slots that offer less than 94% are usually considered low-RTP titles, as many modern releases are set at around the 95% – 96% mark. Therefore, if you’re looking for the highest RTP slots, we strongly recommend that you choose to play online, rather than visiting your local brick-and-mortar casino. You’ll have many more options at your disposal and you’ll be getting a better bang for your buck

Frequently Asked Questions

We suggest that you read our answers to some frequently asked questions below to help you get a full understanding of slots with high RTP.

As our page has shown, no provider has a complete monopoly when it comes to high RTP slots. However, some of the big-name brands regularly produce such games, with NetEnt probably the most prolific in this respect.

No, not at all. RTP is simply an indicator of how likely you to see a return on your stake. However, it is theoretical, so should not be taken literally and instead we recommend that you simply use it as one of many tools to consider before choosing a title.

This is the numerical advantage that the ‘house’ or casino has over players. It is usually expressed as a percentage and varies from game type to game type.

RTP is calculated over a huge number of spins by looking at how often the slot pays out to players versus how much money is gambled. A higher RTP percentage is better, but it is still only an indicator and does not guarantee anything.

As with anything, this comes down to choice and what you are looking to get out of the game. Lower RTP games can often have other features that pay out large amounts – progressive jackpots, for example.

On our page we have outlined 10 of the best slots that have high RTP – with some having a truly memorable percentage up to 99%. Book of 99 is probably the most famous example of this, with the game having one of the highest RTP percentages ever made in a slot.

These phrases mean two separate things. RTP gives guidance on your odds of winning at a particular slot, while volatility refers to gameplay; high volatility slots pay out larger amounts infrequently, with lower volatility ones doing the opposite. Slots can have any combination of high/low volatility and RTP.
