What is RTP in Slots?

RTP is crucial in slot choice, impacts long-term profitability.

What Does RTP Mean in Slots?

RTP is an acronym for Return to Player. This is a technical parameter of a slot machine that shows the level of its return. RTP in slots determined by the provider at the software development stage. It is expressed as a percentage.

For example, if the return rate is 95%, then out of every 100,000 INR, the slot machine will return only 95,000 INR in winnings to players. The remaining 5,000 INR will be the income of the provider and the casino. But this is only a mathematical model. Let’s talk about what is RTP on slots on practice.

Any online casino strives to attract as many players as possible. This means that tens of thousands of people bet on the same slot machines. And RTP works for their overall investment, not for each player individually. For example, let’s take the same slot with a return rate of 95%, in which 100,000 INR are invested. But now let’s assume that 2 people spent this 100,000 INR. As a result, the slot machine will return the same 95,000 INR in winnings, but this money will be distributed unevenly among the players. The first player could spend 90,000 INR on bets and lose everything, and the second player could win all 95,000 INR after the second spin.

So what is RTP in slots? This is a statistical indicator that shows the level of return of the game as a whole, and not for each individual player. It reaches its value over a huge distance – approximately several million spins. So it has almost no effect on the results of one gaming session. It all depends on luck. But if you plan to play the same slot regularly, then this parameter still needs to be taken into account.

RTP in slots it`s a Return to Player, a game's long-term return percentage.

How to Calculate Slots RTP?

Now that we’ve got it figured out what is RTP on slot machine, let’s talk about its calculation. Different categories of games use different formulas. If we talk about slots, then this parameter is calculated by the slot machine providers. Typically, a slot machine is created when the mathematical model is already ready. For example, a provider wants to release a slot with a return of 95%. It is to this value that he adjusts the mechanics, the frequency of winnings, multipliers for slot symbols and other options. Before the slot is released, it is tested to determine the exact RTP value over several million spins.

But besides the theoretical RTP of slot machines, there is also a practical one. That is the result that you get as a result of one, two or even dozens of gaming sessions. To calculate it, you need to divide the amount of winnings or losses by the total amount of investments.

Let’s look at an example. You played 5 times, and each time in the same slot. Each time you bet exactly 10,000 INR. That is, in total you have invested 50,000 INR in the game. The gaming sessions ended with the following results:

  1. Lost 5,000 INR;
  2. Lost 2,000 INR;
  3. Lost 3,000 INR;
  4. Won 1,000 INR;
  5. Won 30,000 INR.

In the end, you ended up with 61,000 INR. If you divide this number by 50,000, you get 1,22, or 122%. This will be your practical RTP over a distance of 5 gaming sessions. That’s why we said that this parameter is statistical, and it reaches its value over a huge distance.

Calculating slots RTP involves provider-set theoretical values and practical results over sessions.

Are RTP and Volatility The Same?

Many players who don’t know what does RTP mean in slots, this parameter is confused with volatility. Both characteristics are technical, and they are included in the game by the provider. And both influence the results of spins to some extent. But the essence of these parameters is completely different.

RTP is the theoretical return percentage. It determines HOW MUCH money the slot will return in the long run to all players. Volatility determines HOW gameplay will occur. In fact, volatility is a measure of risk. The higher it is, the more unpredictable the game will be, but at the same time there is the possibility of getting a very big win.

Volatility is not expressed as a percentage. It can be on several levels. More details in the table.

Volatility levelPeculiarities
HighThe betting results are very unpredictable. There may be long series of spins without winning. The winnings can be either less than the bet amount or exceed it tens of thousands of times.
AverageAverage win frequency and average sizes. Prolonged series of failures are rare. But you can’t win very much here. Typically, slots with medium volatility have a maximum win of up to x10,000.
LowWins occur frequently, but their size is usually small. The maximum win in slots with low volatility rarely exceeds x1,000.

There are also slot machines with medium-high and medium-low volatility. Their gameplay is close to slots with medium volatility.

What is a Normal RTP for Slot Games?

Now let’s talk about what is a good RTP for slots. In the vast majority of games this figure ranges from 90% to 99%. Lower values ​​are only found in some progressive jackpot slot machines. If we talk about the average RTP, it is generally accepted that it is 94-97%. Anything more is already a high level of return, anything less is low.

In practice, the difference even between 93% and 99% is small if you play rarely or only once. But if you plan to bet on the same slot regularly and for a long time, then it is better to choose slots with a higher return rate. The higher the better. This will be beneficial at a distance.

Slot games typically have an RTP between 90% and 99%.
