An online slot can be made better through features and a higher top prize, but the RTP is easily the most impactful improvement players will like.

You might already be familiar with RTP. The RTP stands for the return to player. RTP is basically the return that you should get if you play a slot for a really long duration. So the RTP will give you an idea about how much you can win from a slot.

The RTP can’t be 100% because the online casinos won’t earn anything that way. Still, plenty of slots offer a high RTP, like 97% or 98%.

In this guide, we will share the best RTP slots. Most of the highest RTP slots can be played here at BETO. Our catalogue is constantly being upgraded, so we will have the newest best RTP slots added to it soon.

All experienced online slot players look at the RTP of a slot to determine whether it is worth playing or not. If the RTP is too low, experienced players will avoid the slot because it won’t give them great returns.

For instance, a slot with an RTP of 97% means you should get €97 back if you bet €100 (house edge is 3% in this case). In the long run, your winnings will surely be close to this figure. Obviously, you can win more or less in the short run.

In short, the RTP gives you an idea of how risky it is to play a video slot. You can go for online slots with a low RTP if you are fine with a higher risk. Still, we will recommend that you always try to use the RTP to decide whether to play a slot or not.

The fact is that the RTP only applies to the long run, so you can win a lot or lose a lot during the short run. You can lose your entire bankroll, or you can multiply it quickly.

All online slots are random and based on luck, but the RTP is a good indicator of how much you can get back on average. This theoretical percentage will help you pick the most favourable slots.

What is a high RTP slot? Well, a high RTP slot is any slot that offers an RTP above 96.50%. 96% is the average RTP, so you can find a lot of mid-range slots near it. Finally, a slot with an RTP below 95% is considered a low RTP slot.

The best RTP slots make it easy to enjoy the experience without worrying about losing money. Here are the slots that offer the highest RTP percentage at the time of writing this guide.

  • Book of 99 by Relax Gaming: 99% RTP
  • Ooh Aah Dracula by Barcrest: 99% RTP
  • Ugga Bugga by Playtech: 99.07% RTP

The RTP of some of these slots can differ from casino to casino, so you have to check the RTP before you play.


Should you Focus on Playing High RTP Slot Machines Online?

There is no doubt that RTP is one of the important factors when deciding which slot games to play. However, it isn’t the only factor you should consider. There are some other important factors like the Max Win and Variance.

The RTP will only tell you how much return you can get on average, but it can’t tell you how often you will win and how high the potential of an online slot is.

Variance is significant because it decides how often you will get wins and how big those wins can be. Low-variance online slots will give you consistent wins and allow you to get returns easily. On the other hand, the high variance rarely give wins and take a longer time to give you the average returns.

High variance slots are risky, but they can make you rich in no time. So you have to consider the risk and rewards when deciding which video slot to play. The Max Win is also worth considering because some slots can give you wins higher than 10,000x of your bet, while some slots give away much lower payouts.

To summarize, the RTP is an important factor, but it should always be used with other factors to judge a slot correctly.


Why Should you Care About Online Slots Payout Percentages?

Steam Tower Slots Payout Percentage is 97.04%.

Several slot game lovers only care about the gameplay and fun elements and don’t worry about RTP or other factors too much. They think that the RTP doesn’t make that much of a difference, and this is true in the short run. However, the RTP will always be an important factor in the long run.

In short, it is wrong to think that the RTP doesn’t matter. A higher RTP will give you higher returns in the long run, so it is best to play high RTP slots if you want to win.

Maybe, if you only want to play a slot for like five minutes and then start playing another one, the RTP shouldn’t be a big concern. If you want to play one slot for half an hour or more, the RTP should be considered.

Remember that going for a lower RTP is fine if you think the slot is fun. You will most likely lose a little money if you play all slots for a long duration, so you should always play for fun and enjoy the wins you get in the short run.


The Math Behind Slot RTP Explained

RTP can be confusing because it is the average return you should theoretically get. If you only do a few spins, you may not get a single win and lose money. On the other hand, a few spins can give you massive wins and higher-than-expected returns.

In the end, your returns will always come close to the RTP if you play a slot for a long time. How long you will have to play a slot to get the returns equal to the RTP will depend on the variance of the slot and other factors.

Steam Tower (NetEnt)

The RTP is calculated after a million or billion spins so that the average returns from a slot can be calculated accurately. Still, there is no guarantee that you will get returns that match the RTP. After all, a slot is a game of chance, and this is what makes slots fun.

For instance, the Steam Tower slot by NetEnt offers a fantastic theoretical RTP of 97.04%. However, you may get back only €30 or win €1,000, depending on your luck. You may even win the Jackpot worth 2,000x of your bet in just a few spins.

In short, you have to accept that the RTP does not dictate the winning potential. The RTP only ensures an average return over a long time. So you may run into losing or winning streaks and think the slot is fishy. However, we assure you that this is normal, and you will get back most of your money easily if you play for a longer duration.


Theoretical RTP - Online Slots Payout Percentage

You might have heard of theoretical RTP and wondered what it means. Some people may think that the RTP is unreliable when they read theoretical RTP. However, the truth is that the theoretical RTP only means that this is the return you should theoretically get back on average, and your actual return can be drastically different.

Even a slot game with a very high RTP will make it difficult to get back the average return if it has a high variance. Once you become used to playing slots, you won’t have to worry about the theoretical RTP.

Gaming Authority and Low RTP Games

Malta Gaming Authority has reduced the minimum RTP from 92% to 85%, so online slots come closer to slots in land-based casinos. One of the reasons for doing so is to allow operators to lower RTPs and remain competitive in jurisdictions with high taxes.

In the future, more slots will have a lower RTP, which will increase the worth of the slots that offer a much higher RTP.

RTP in Slot Machines vs Casino Bonuses

Most online sites will try to attract players by offering them casino bonuses. The bonuses can include bonuses that require you to meet the wagering requirements before you can withdraw money. For instance, if you deposit €100 and get a 100% match bonus, you will get an extra €100. However, you might have to bet the bonus amount 40 times or more to be able to withdraw it.

You might wonder what this has to do with the best RTP slots. The best RTP slots offer you a really high RTP and allow you to get back most of your money easily. So you can use the highest RTP slots to match the wagering requirements and withdraw your winnings easily.

However, you have to read the terms and conditions to ensure that you are allowed to play the highest RTP slots before you grab the bonus.


Importance of High RTP in Casino Games & Slots

The RTP value is one of the most important values that should be considered while playing video slots. The higher the RTP value, the lower the house edge will be, and the higher will be your chances of getting great returns.

We aren’t asking you to ignore the other factors. Some of the highest-paying slots, like slots with Progressive Jackpots, have a low RTP. However, people love playing them because of their winning potential. The variance is another crucial factor that affects the gameplay and your returns.

Whenever you visit online casinos, always look at the RTP figure and think about whether you are comfortable with it or not. In short, never hesitate to play slots that offer the highest RTP.
