The RTP percentage of a slot machine

is one of the most important characteristics to consider before betting. The acronym RTP stands for “Return to Player”, which in Italian literally means “Return to the Player”, and tells us how profitable a slot is.Best Online Slot Games to Play in 2021 - InfiniGEEK

As we always say on, the best way to see how a slot works is to try it for free. That is why on our site you will find one of the most complete catalogs of high quality and free Italian slot machines , together with a lot of useful information to get the most out of your games.

If you like to play in a more empirical way, on our site comptegratuits you will find a complete handbook on the functioning of the slot machines and slots available in the aams online casinos . This handbook includes topics such as volatility, RNG software, advice on how to optimize your play and weigh an index of slots sorted by their RTP.


When looking for information on a slot, the RTP percentage is one of the first to be found. As you probably already know and as we mentioned at the beginning of the article, RTP is the rate of return of a game. By any chance you don’t know what exactly this number means? You are lucky! In fact, in this article we explain step by step what it is, how it is calculated and why it is so important.

In fact, a simple example is enough to understand what RTP means.

Imagine you have wagered 100 coins in one game session. If the RTP of the slot is 95%, the statistic says that the most likely thing is that when the game ends there are still 95 coins.

We have made an example with small numbers (only 100 coins played) but the RTP is calculated on much larger numbers, taking into account the stakes of all players who play the same slot in a given period.


The RTP is a theoretical fact. Obviously, the result of each game is different: there will be players who with 100 tokens played will still have less than 95 tokens (or much less), as well as there will be players who always with the same 100 tokens will have more than 95 available. tokens (or much more).

If you think about it, if the RTP was always satisfied, no one would ever win playing slots (everyone would get 5 and then everyone would lose some). Betting would no longer be exciting as you would know in advance what will happen.

Fortunately, luck can change everything in all casino games . Since every game is different, the end result can never be exactly the same. Let’s see how the RTP is calculated and what factors intervene in such a way that at the end of a game session your accounts balance.


I have not yet mentioned the fact that as far as RTP is concerned, Italian operators are obliged to report it in all the games they offer. Here we have focused on slots RTPs, but actually all Italian casino games have their own RTP. But who is responsible for calculating and verifying that this data corresponds to reality?

Obviously, the higher the RTP of a game, the more attractive it is to gamers. Similarly, if an operator offers games with low RTP, their payout will in principle be higher but in the long run players may end up getting tired and switching casinos (or providers).

This is why calculating RTP is something that shouldn’t be done lightly, so slot machine software providers take into account the balance between the interests of the players and those of the casino. The secret to satisfying both sides is to create exciting games, with an RTP approaching 100%, but always staying below this percentage. Nonetheless, it happens that some games, including some slots, even break through that percentage, in the actual data accounts for certain periods.


Calculating a game’s exact RTP percentage is relatively straightforward – all it takes is a significant series of play sessions, long enough to activate all the bonus games and extra features of the slot.

The overall RTP for such a slot as the Book of Ra , Book of Ra Magic and Book of dead will be the result of the average of all the results obtained in each of the games. Matches for calculating the RTP are played in exactly the same way as when betting for real money and in the following ways:

  1. The game version is the same as when playing for real money from any device.
  2. The maximum bet is selected.
  3. All the payment lines or the various combinations available are activated.
  4. The game is considered over a long period

In summary, the result of this statistical research is a number that tells you how much you win when you play by putting all the meat on the stove and over a long period of time. That’s why you often find texts that speak of “RTP Massimo”.

However, the truth is, you can’t always play this way. In fact, what happens if all the payment lines are not activated? What happens if the maximum bet per spin is not activated? In these cases, the percentage of RTP is different and generally lower. This is why in some countries they have begun to require that the percentage of RTP be expressed in different categories, rather than in absolute numbers.

You may have found slots where the indicated RTP is between 92.6% and 96.4%. This means that if you play for a short time or in a game limited to the base game, the RTP will be 92.6%, but if you extend the session long enough to benefit from all the bonuses of mini games, special symbols and the full range of slot features, the average will rise to 96.4%.


When a company like Playtech or Netent develops a new slot, they already have a clear idea of what the game’s RTP will be from the start. These companies are equipped with real statistical laboratories, in order to provide their software with a precise RTP, which then indicate to the operators (casinos) when they sell their game.

However, if you play in regulated jurisdictions (such as in Italy with the Customs Agency which incorporated the AAMS), you can be sure that the RTP of the games and other aspects such as the operation of your RNGs will have been verified by at least one independent laboratory of the brand that created it and of the casino that makes the game available.

These are international companies dedicated specifically to this work. These include: GLI, BMM , TestLabs, Trisigma Q3 and others. These companies test the games by verifying that their characteristics comply with everything necessary to be considered legitimate and legal games of chance.

The next step to see if slot machine features are true and compliant with the rules of each jurisdiction depends on each country’s management. And in those places where there is no government institution dedicated to regulating the game, those responsible for this procedure are the respective “Gaming Council”.


After reading the previous paragraphs, you may be tempted not to take into account the RTP percentage of games anymore, preferring to intuitively launch yourself to try your luck without further ado. It is true that although it is calculated in a scientific way, the percentage of RTP only predicts what could happen (in a probabilistic way) in the long term and playing in a certain way.

Regardless, the Return to Player is important as it lets you know what you can expect from a game:

  1. Only when you know the RTP percentage can you have realistic expectations of your chances of winning against the house edge.
  2. If you are aware of how the RTP of a slot machine is calculated, you can reproduce these conditions during the free sessions.
  3. Even if you play just to experience the thrill of luck, your sessions could be even more exciting and even more profitable if you choose the slots with more favorable RTP.


The RTP of online casino games is of paramount importance not only when you play, but also when you get a bonus for playing. As you probably already know, in order to convert a bonus into real money and be able to withdraw it, a wagering requirement must be met. All bonuses have a wagering requirement, the so-called rollover.

The rollover is the number of times you have to wager the bonus money if you want to cash out the winnings you get by playing it. For example, if a € 10 bonus has a rollover of € 40, it means you have to play until you have wagered € 400 in order to be able to withdraw it.

To add a bit of difficulty, many casinos choose to hide games with higher RTP, or degrade their computation. Also, to meet the required wagering requirement it is not possible to bet on simple bets like red / black or odd / even on roulette, or on games like blackjack that are discarded or contribute only 50% (or even less). If we take the example above, instead of playing € 400 you should play € 800 or more, in order to convert the bonus into real cash that can be withdrawn.

The importance of slot machine RTP lies precisely in this: they generally contribute 100% therefore allow you to meet the casino’s wagering requirement faster and completely.

Before wagering the bonus, however, you should always check the Terms and Conditions to make sure that the slot you have chosen has not been devalued by the operator or even excluded (because maybe it has a high RTP and would allow you to transform the bonus without problems).


In general, we believe that an acceptable RTP is 95%. When it is above 96% it can be considered good and above 96.5% very good. But are we sure that slots and other games with lower RTP should be discarded?

At first glance, it makes sense that the higher the RTP of a casino game, the higher the player’s chances of winning. And in principle this is true, although there are actually some nuances to consider.

For this, it is necessary to investigate, since the RTP is not the only thing that should influence the choice of a game in view of the collection of the bonus. Other factors to consider are volatility (variance), which is directly related to the risk you run on each bet and the chances of winning. In order to redeem the bonus, i.e. to turn it into real money by meeting the required wagering requirements, games with a lower than average volatility percentage are more successful.
