Dispersion of winning (volatility) in online slots

While choosing a slot, the player needs to know not only the external specifications (the design and graphics, plot, colour scheme) but also profitability. Usually, players pay attention to the RTP (return to player percentage). But this number shows only the absolute mathematical expectation of the game. It does not show the winning period (number of spins) and winning amount.

As you know, the slot machines accumulate player's bets and distribute them in winning. How much money the slot will return to players, depends on settings of RTP. This value is usually from 95 to 99%. This value is achieved only at a long distance (millions of spins). Well, who would agree to play in a slot machine, which would decrease 1-5 cents of the dollar in each spin from the account balance? Therefore, the slots give out winning at random. It corresponds to the dispersion (or volatility). It shows, how often the slot machine will give the winning, and what amounts it would be. For example, slot 1 gives often, but a little - it means it has low dispersion. In slot 2, the winning is rare but significant; it is a slot with high dispersion.

The volatility has a huge impact on the bet and the balance on your account while playing at the slot. If in slots with a low-dispersion, we can put 1/50 - 1/100 of our balance, then in high-dispersion slots, it will good to put already 1/500 from the balance. In other words, the higher the dispersion value, as long the row of losing spins, the winning will be much bigger but rarely.

Dispersion and cycles in online slots

How does one understand the level of volatility that an online slot has? You can look at the coefficient of the maximum winning. Online slots with maximum pay-out of coins 10,000x+ usually have high volatility. If maximum winning is from 2000x up to 5000x - average volatility, and if maximum winning is 1000x - low volatility. Often it is so, but there are exceptions.

Dependencies of values in the slot

As you can see on the table, there is a direct connection between the coefficient of "the maximum winning" and the length of the cycle. Each slot has its cycle length, which the provider hides.

Our testers established data stated in the table by testing slots. At the beginning of the cycle, the slot machine "collects" money in the prize pool and when it is full "fires" with the big win.

At the end of the cycle, the slot machine starts spreading winnings, the size, and frequency of which depends on the dispersion. We believe that it's in this phase of the cycle, the player has increased the opportunity to hit a big win. To identify the stage of the cycle is possible, only in practice - in the free game. You can learn more about choosing a slot for winning.

Progressives

In online slots with a progressive jackpot feature, "the dispersion" is exceptionally high. These slots have the longest cycle and collecting money for a huge hit. Then the whole jackpot goes to one lucky person. Of course, it is tempting to become the owner of a giant winning, but the probability of this event is about 1 to 50 million.
