If you have ever read slot machine descriptions, you have probably come across words like variance/dispersion and volatility. They are often used as synonyms implying that both terms mean a deviation from mathematical expectations. However, in reality, these words have different meanings. It is time to figure out things so that to use the right terminology.
What is variance/dispersion
Most often, this term is used in poker, but its scope is much wider. Variance or dispersion is a statistical term that means the amount of deviation from mathematical expectations. In other words, variance or dispersion shows a deviation from a specific RTP (Return To Player) value. For example, the RTP of some slot machine is 98%. This means theoretically that a gamer can get 98% of the money spent in the game. However, it is worth considering that this value refers to the long-term game of many gamblers. Therefore, with few spins, RTP will not match the declared figure, that is, the variance or dispersion will be high.
What volatility is
Volatility is directly linked to the gameplay. This term refers to the qualitative and quantitative indicators of winnings, that is, the frequency and size of payouts. There are three types of volatility:
Low. Slots with low volatility are not very risky. In such slots, winnings occur quite often, but, as a rule, these are small amounts. Such games are most suitable for gamblers who do not chase large payouts and prefer enjoying gameplay itself.
High. Slot machines with high volatility bring big wins, but not often. Such slots are suitable for patient gamers ready to battle for jackpots.
Medium. Obviously, average volatility is the golden mean. Most modern slot machines feature exactly medium volatility.
Where to play slot machines

Thus, you can find the most suitable slots for yourself. You can play online free and without sign-up on https://casino-advisor.co.uk/.
