In this article we will talk about a characteristic of the gaming machine called variance. First of all, the variance should not be confused with the payout percentage of slots. If the payout ratio represents a percentage of bets in the payment, the dispersion means the degree of risk when playing on a slot.
Thus, all slot machines can be divided into those with a low, medium and high dispersion. First do not have a high payout ratio, but winning combinations there are quite often. The latter excite fantasy players with a huge benefit, but the combinations are formed there extremely rare. The most slot machines have an average dispersion.
What about the variance of slots?
No casino or slots manufacturers do not apply a lot of variance to their slots, but more experienced users can tell about it from the pay table.
The best way to determine it is the highest coefficient of variance paid by a combination of the most unusual characters. Some resources in the network even have specific division slots on this basis: maximum payout of h5000 means that this slot is with low dispersion, h10000 - an average, over h10000 - high.
But we think this approach is too simple, because it is not always possible to determine the dispersion of the slot by a payout ratio only. Therefore, we need to consider additional factors.
For example, in 5 -reel slots the difference in the coefficients of payments in a combination of three, four and five characters. If a combination of three or even four identical images are paid much less than five characters, this slot is may have high dispersion. If the difference in payments between is not very high, it may have low variance.
You also need to take into account special characters and their features. If the game has a symbol of Wild, appearing on the screen at the entire reel, the combination will be formed often. Comparing it with the ratio, you can get an idea ofit's dispersion.
Of course, this allows only approximate estimation of the variance of a slot. Exact details can be found only in the documentation or the specifications of the manufacturer. Less accurate, but a highly effective way is testing a slot in the training mode. Fortunately, it is possible in most online casinos.
Check the bankroll after hundreds of other spin to clarify it. If during this time large combinations did not drop, but the amount is not changed much, the dispersion of the slot can be considered low. At the same time, frequent payments, slightly higher or lower than the total bet.
If you methodically lose for a long time, and then you get a very large combination, with a streak of bad luck later - the dispersion of this slot is high.
Almost always high dispersion is in slot machines with huge progressive jackpots. For example, Mega Moolah by Microgaming or Megabucks by IGT.
Features of slots with different dispersion
Of course, slots game with high variance need a large jackpot, otherwise the money could end sooner than you get at least one combination while playing. At least, use low cost coins (but do not forget about the rules of getting a jackpot, if you choose such slot).
On the other hand, slots with low dispersion allow you to play for a long time, even if your bankroll is not large. But here you will not have a chance to break a big jackpot in one spin.
In the end, it's a matter of personal preference and financial capabilities. Choose depending on how much money you want to risk. If you are strapped for cash but want to play a little longer, choose a slot with low dispersion. And those playing for an incredible jackpot, just need to select the appropriate slots.
