rtp on slot machines

When it comes to slot machines, the market is oversaturated. They are launched daily, so facing hundreds of titles may be overwhelming for both newbies and seasoned players. You can choose slots by the provider, theme, video and sound quality or bonus features they offer. Another factor you may take into consideration is the volatility of a slot machine and its hit frequency.

Although all of these factors are important when choosing a slot game, there is another one that may be crucial to the gameplay and we often oversee it. It is a return to player or simply RTP. Are you interested in an RTP on slot machines and what its impact on the gameplay is? Stay with us as we bring you a comprehensive guide to an RTP in slots with examples of high RTP slots you can start playing today.

What is RTP?

An RTP is all about the mathematics behind a game. A return to player represents, as the term itself suggests, the percentage of the total money wagered on a slot machine that is returned to the player. An RTP varies from one slot title to another, but it is expressed always in the same way, as a percentage. If a slot machine has an RTP of 96%, it means that it will pay £96 on £100 wagered on it in theory.

Before we go into detail, let us first tell you that an RTP is calculated over the long term. So, when choosing a slot machine you will play for an hour or so, you cannot expect that an RTP will reflect your future winnings. Slot developers run tests on hundreds of thousands of spins to get an RTP. When we play a slot game, we never play that many spins in a single session. And, as you know, each spin is an individual event. If a series of spins ends in a loss, the next spin can be big enough not only to cover your previous losses and but also to give a boost to your bankroll.

How RTP Works?

Now that you understand that an RTP does not affect individual spins, you should be aware of the fact that it can still indicate whether a slot machine is worth your while. To put it simply, the higher the RTP the better. When choosing a slot machine, you should go for those with a higher RTP since the one with a 97% RTP will pay better than the one with an RTP of 82% only. It does not mean that you cannot lose while playing the former, but it provides you with better odds of winning.

In this chapter, we would also like to address an RTP in progressive slots. Unlike in regular video slots, an RTP of progressive slots may be a bit misleading. The value of their RTP comes from progressive jackpots, which are included in their payout rate. However, these prizes come rarely and you have extremely lucky to win them. If progressive jackpots would have been left out from the calculation, the RTP in these slots would be considerably lower. Still, there is always a chance to hit a life-changing progressive jackpot.

Another thing you should bear in mind is that online casinos cannot change the RTP of slot machines they offer. These values are set by the developers and they are a given, so RTPs are not configurable at the operators’ end.

RTP in Online vs. Land-Based Slots

If you are a slot enthusiast, an RTP is one of the reasons why you should start playing online slots. While many land-based slots have been turned into online slots, they are not the same games. The main difference is in their RTP. While land-based slots have an average RTP of 85%, titles you can play at online casinos have an average RTP of 96%.

Running a land-based casino business comes with many expenses, so operators must make money to cover them. Also, brick-and-mortar gaming venues have a limited capacity when it comes to the games they offer. On the other hand, online casinos can offer hundreds if not thousands of slot machines that can be played by an unlimited number of players at the same time.

Some of the ways how developers adjust a slot machine to have a lower RTP is by changing a few rules. For instance, the same feature, like free spins, can be triggered by two Scatters in the online version of the game. To unlock the same feature in the land-based game, you may need three special symbols.

Slot Variance vs. RTP

Slot variance or volatility is a term that indicates how frequently a slot machine pays. On the web, you can find low, medium and high variance slots. Low volatility slots pay more frequently yet the payouts they deliver are of lower value. Highly volatile slots pay out larger prizes less often while medium volatility slots are somewhere in between. They promise balanced gameplay.

What you should keep in mind is that some high volatility slots have a high RTP thanks to their bonus features where big wins can land. However, these bonuses rarely trigger, so you may experience a long series of dead spins before it happens. These slot machines are more suitable for experienced players with a solid bankroll.

In a nutshell, the volatility of a slot machine is all about how much risk it involves. So higher the variance, the more risk involved. Take all these factors into account when choosing the slot game you will play.

High RTP Slots and Bonus Wagering Requirements

When using casino bonuses, slot machines are the best bet. Not only that they can pay out some hefty prizes, but they are games that contribute to the wagering requirements at the highest rate of 100%. However, if you visit the terms and conditions of any gambling site, you will notice that some slots may be completely excluded from wagering requirements. And guess what? In most cases, these are high RTP slot machines.

Although we don’t like the fact that operators exclude some of the best paying slots from bonus wagering requirements, it represents the confirmation of what we have stated earlier in this article. An RTP in slot machines matter and you should pay attention to its value whenever you choose a title to play.
