The term "volatility" was borrowed from the theory of probability. It explains the deviation from the mathematical algorithm and the expected result.
It is important not to confuse volatility with the return percentage (RTP). The return rate shows the volume of bets that a player will be able to return during a continuous game. The volatility is an indicator of the winning frequency.
Three types of volatility are used in slots:
Low. A game brings frequent but small prizes. In most cases, the winning amount does not exceed the size of the current bet.
Medium. The win rates are almost equal to the sum of the prizes received.
High. Winning combinations do not appear often. However, the one-time prize amount can be several times higher than the bet made.
