Best High RTP Slots to Give a Spin in 2021

Anyone who has tried their luck at slot machines knows that it’s both a thrilling and terrifying experience. Of course, losing is never fun, but most people hope to win big, especially when playing high RTP slots.

Many novice players ignore a slot’s RTP. However, the return to player value is one of the most important stats you need to consider before jumping into the world of betting games.

The Return To Player Rate

The RTP rate is the percentage of wagers that the game will return to a player in the long term (typically at least one million plays). So the higher the RTP, the more you can win back, theoretically. 

By the end of this article, you’ll have all the RTP knowledge you need to improve your betting skills. 

How much does a slot game pay back per spin?

The return to player rate can be considered as the opposite or reverse of the house edge. For example, NetEnt’s Starburst has an RTP of 96.1%; which means its house edge is 3.9%, and that if a person wagers £100, they should get back £96.1 per spin. However, many players can attest that this doesn’t often happen.

As we mentioned before, this figure is calculated over a massive number of simulated spins (at least one million, but it can go up to billions). As a result, there can be several spin batches that aren’t even close to the average, meaning that if you wagered £100, you might get back £50 or even less than that.

That is the random nature of slots. However, if a game is played long enough, the player will see their average returns more closely reflecting the RTP value.

The RTP value is also known as the payout ratio. If you hear about online slots that offer the best payouts, it typically means they are the slots with the highest RTP rate. Generally, online casino slots have a higher RTP rate than land-based casinos. 

For example, games in a Las Vegas casino may have an RTP of 75%, while the same game online may have an RTP of 95%. This means you have the probability of getting back £75 if you wagered £100 in a Las Vegas casino, but you may get back £20 more if you played the slot online. 

This variance is because in-person casinos have a higher overhead cost than online casinos, so live casinos need to recover the costs somehow. This is a considerable difference and the reason why the best payout slots are online.

How often can you win?

The hit frequency rate is the probability of winning on a single spin, and it determines how often you can win. This probability varies widely and can have a rate anywhere between 10% to 50%, meaning you can get a hit once every 10 spins to once in every two spins. 

Although, a higher hit frequency doesn’t mean you will win more. One large payout may be equal to several small payouts, so a hit frequency cannot determine whether a slot game will give you back more money.

The Best RTP Slots and Where to Find Them

Luckily for online gamblers, they can find the RTP slots with the highest values online.

So what’s considered a high RTP slot

Well, in short, it’s the slots that have an RTP rate closest to 100%. Therefore, high RTP slots may be anything at 98% or above, while mid-range RTP slots fall between 95% and 97.99%, and any slots with RTP rates lower than that are considered low payout slots. 

RTP and Volatility

You may not feel any difference when playing a slot with 99% RTP or 94% RTP; this is because the payout probability is calculated over an enormous number of spins. However, your volatility will definitely impact your experience because it determines how much money you’ll be paid.

Volatility (also known as variance) is a term that is used to assess the risk of losing a wager and the frequency of payouts. Therefore, it determines whether the game you are playing is high-risk, medium-risk, or low-risk and what kinds of rewards you can get. 

High Variance Slots 

Highly volatile slots have the potential of delivering big wins. Most of these wins come in the bonus features, which can require thousands of spins to trigger. This is because the winning amount in these features can be very high. For example, it may be multiplied by 50,000 to your wager per spin.

Since big wins are few and far between, the probability of you winning big is relatively low. Due to this, high variance online slots can eat through your budget, and you may get very little, if anything, in return. Hence, these slots may not be a great option for novice players, casual players, or those uncomfortable with taking big risks. 

Low Variance Slots

Low volatile slots trigger small payouts at a consistent rate but don’t deliver big wins often. This is because they are made for people who want to limit their risk and get some payout, even if it’s little. However, this doesn’t mean that the game will not trigger big hits at all.

People who like to take calculated risks may prefer high variance in slots with larger winning potential, but low volatile slots are good for beginners and casual players. Over the long term, the payout can still be generous as most low variance slots feature high RTP values.

Jackpot Slots and RTP 

This type of online slots are different from regular ones because a portion of the RTP value is held back in a progressive jackpot pool collected for a future jackpot win. Therefore, RTP rates for jackpot slots are lower than the RTP rates for regular slot games.

A helpful tip for low payout games is to find medium volatility ones that offer fixed jackpot prizes. Fixed jackpots may not win you millions in cash prizes, but your chances of winning them are much higher than with progressive jackpot slots. Plus, fixed jackpots also offer better payouts through their bonus features. 

How Is RTP in Slots Calculated? 

Calculating the RTP rate is easy enough. All you need to do is divide the total payout delivered to players by the total amount wagered. For example:

Total amount paid out: £19,200

Total amount wagered: £20,000

RTP rate = total amount paid out/ total amount wagered = 19,200/20,000 = 0.96 or 96%

This means that the house edge is 4%, and the slot has a medium-level RTP.

Keep in mind that the RTP amount is calculated over a minimum of a million spins. Most often, the number of spins is even higher, from several million to even billions.

Best Payout Online Slots for UK Users 

When it comes to slots, the word “best” can be attributed to different elements. For example, some people think that high RTP slots are the best since the house edge is lower, and you can win more money. For others, best means a slot where the biggest wins are possible.

Statistical Consideration for Online Slots

Apart from RPT, players can use several other statistics to determine how much a slot pays out. Let’s take a look at a few of them:

Bonus Frequency

This stat tells you the probability of triggering the bonus in a slot game. The bonus frequency, like the RTP, is also calculated over millions of spins, so you can get lucky by kicking off free spins more frequently than what the stats say. However, again, a bonus often doesn’t guarantee the slot will pay out more.

Hit Frequency

The hit frequency is how much probability you have of winning on a single spin. Most games have a hit frequency between 10% and 50%, which means they have one win in every 10 spins to one win every two spins, respectively. However, as previously mentioned, these stats are all calculated over millions of spins, so the average may vary drastically if you calculate the hit frequency over a short term. 

Jackpot

A jackpot denotes the biggest win possible with a single spin. They can be won from a combination of symbols and wilds. Slots with a progressive jackpot typically have a lower RTP since some portion of the wager goes towards funding the progressive jackpot pool, which is to be won by a player.

In addition, most progressive jackpots games require players to wager a maximum amount to become eligible for a jackpot.

How to Find RTP Rates?

The UK Gambling Commission makes it mandatory for gaming machines to display their RTP rates or the probability of winning a prize. Players can find the RTP by clicking the slot’s paytable button, which may be marked by an “I” or the word “Paytable.” Here you can find out what the RTP is, how much you can win for different symbols, information about the bonus features, and creating winning combinations.

Be sure to check the paytable since many providers ship their online slots with varying RTP rates, depending on the market. Also, you need to keep an eye out for dishonest offshore slot machine operators who can set the lowest possible RTP level and not tell their players what it is.

High RTPs and Casino Bonuses

As a new player, slot machines will offer several welcome offers, including bonus cash and free spins. Typically, bonus cash from these offers is subject to wagering requirements or playthrough.

For example, if you are offered a bonus of 100% with a 30x wagering requirement of £100, you will need to play through the bonus 25 times or £2,500 to withdraw the bonus cash

In theory, playing high RTP slots can make it easier for gamblers to clear their wagering requirements and let them access the bonus cash. Therefore, some online casinos don’t allow wagering from specific slot machines, particularly those with high RTP levels. 

Hence, you must check the casino’s terms and conditions before you select a high RTP slot intending to get a bonus offer.

Land-Based Casino Slots RTP

Have you ever wondered whether playing in physical casinos is more lucrative than playing in online casinos? In Nevada, the minimum RTP is around 75%. Considering that most of the online slot machines we have recommended in this guide all have RTP’s above 95%, you can see a significant difference in the profitability of online and land-based casino slots. This is because physical casinos have a higher overhead cost which is recouped from the RTP value.

In Conclusion 

RTP rate isn’t the only stat you need to consider when selecting which slots you play; however, high RTP slots are more appealing, and if you can find slot machines with high RTP values, it’s a good idea to give them a go. 

The more times you spin a slot over a long period, the closer you get to its stated payout ratio. However, there is also a high probability that you will never be able to hit the exact return to player figure because of volatility and the completely random nature of slots that pay some players more than others. 

When playing slots, it’s important to not focus on how much you can win; it should be treated as a fun and exciting pastime— and if you are making some money out of it, that’s just a bonus. Although, RTP should not be treated as the secret to winning all slot games. Your main factor is luck, which ultimately determines how any game plays out.

Do slots pay more at night? 

Typically, the game that most people play has the highest chance of paying out. That’s because a higher number of people are placing wagers on it, so there is a higher probability of jackpot combinations being formed. 

However, since the payout ratio is calculated over millions of spins, there is no slot machine payout schedule, and a game may not pay out in days or even weeks. That’s the nature of random number generators under which all slots operate. Hence, slots paying more at night is just a myth.

What is the best day of the week to go to a casino?

Since random number generators govern slot machines, no one can predict when a slot will start to payout. However, if you want to beat the rush and play some games in peace, Monday mornings and afternoons are good times to go to the casino. However, this will not guarantee you’ll win.
