Volatility, colloquially known as dispersion as regards a casino, is the risk involved in playing a particular game. When it comes to online slots, volatility refers to the payout frequency and the amount that players expect to win after betting on a specific slot. Medium-sized volatility is the compromise between high and low volatility.
A slot with high volatility will reward players with higher amounts, but the payouts are not regular. On the other hand, a slot with low volatility will pay players with small or mid-sized amounts more frequently. High volatility slots are for big risk-takers and are riskier than low volatility slots.
