Volatility
A slot machine's propensity for frequent small wins versus infrequent large wins, expressed as low, medium, or high.
Detailed Explanation
Volatility describes the risk profile of a slot game — specifically, how the mathematical payback is distributed between small frequent wins and large infrequent wins. Low-volatility slots pay smaller amounts frequently, keeping the credit balance relatively stable. High-volatility slots may go 100+ spins without a meaningful win, then pay a large multiplier.
Volatility is an important game selection factor. Low-volatility slots are appropriate for players with limited bankrolls, those seeking extended play time, and those rating for comps at a specific minimum bet level. High-volatility slots suit players who want the possibility of a transformative win and have sufficient bankroll to weather extended dry spells.
Game volatility is influenced by the frequency and size of jackpot tiers, the presence of progressive jackpots, the structure of bonus features, and the multiplier values applied to base game wins. Most game manufacturers provide volatility ratings.
