RTP of slots. Dispersion and Volatility

RTP – short is for the phrase Return To Player. This indicator tells us how much money we will lose out on an infinite distance or the theoretical yield of the slot. Perhaps it is not necessary to explain the fact that people coming to the casino still lose money in the long run.

rtp percentThe average RTP rate in licensed slots ranges from 90% -99%. For example, we play with $ 100 at the rate of $ 1 per spin in the slot with 97% RTP. This means that for every spin, we will lose $ 0.03 (3% of $ 1). Since we consider the situation in the “vacuum”, we must understand that this slot would simply be not interesting because each spin, instead of winning, we would simply lose money, winning the $ 0.97 for a bet of $ 1.

Let’s not burden you with numbers and take a look at some examples and introduce a new term – the dispersion

Imagine a situation where you made a spin and didn’t get any combination. In other words, making a spin worth $ 1 you get $ 0. This would mean that in this particular spin the RTP value was 0%. You make the second spin and get combination that got you $ 2. In this case, RTP was 200% Sure, this example will be valid only in the event that only one person plays the casino. Different slots behave differently. Here is the situation you are probably familiar with – one slot rolls a winning combination with each second spin in the form of small gains, while the other slot lets you win only one time out of ten, but gives you a large sum.

If you draw a graph, it will be much clearer. The green line indicates RTP and alas goes in a downward direction. That is how the game, in which we would lose $ 0.03 per spin or zero dispersion, would look like. But try and add the value of the dispersion, and we get get a lot of different variations of slots. The red graph shows the behavior of low-dispersion slots with high frequency of rolling combinations. Blue graph shows highly dispersive game slots, for example Book of Ra.

And now comes the fun part! Many people are advised to play slots with high RTP. But the thing is that high RTP comes in low dispersion slots, where you can win multiple times, but a rather modest amount money. Thus, these slots are saving us money in the long run, but do not give the opportunity to win big in a particular game session.

In the long run we lose less money and during some gaming session we get small amounts, but frequently. The problem is that small gains make us want to play the game further, and the longer we play, the more we lose.

We lose more money in the long run. In certain game sessions we may rarely win, but winning amounts are much larger.

You can choose a more suitable type of the game. If you are ready to pay more for the opportunity to get more sizable winnings, then you’ll like the high dispersion slots. If you do not like the protracted series of empty spins, note the slots with low dispersion, but forget about multiplications of x1000 and more.

Slots with high dispersion usually have a low RTP.
