What is volatility in slots?
Volatility in slots (used interchangeably with variance) describes how wins are distributed over time. Low volatility slots pay out small amounts frequently. High volatility slots go longer between wins but deliver larger payouts when they do hit.
How it affects your session
On a low volatility slot, your balance tends to stay relatively stable, with regular small wins keeping you in play. On a high volatility slot, your balance can drop significantly during dry spells, then recover or exceed its starting point when a big win hits. The same RTP can produce very different session experiences depending on volatility.
Matching volatility to your bankroll
Low volatility is more appropriate for smaller bankrolls since losing runs are shorter. High volatility suits players with larger bankrolls who are willing to absorb variance in exchange for the chance at bigger payouts. Most slot providers now list volatility in the game info, and casino filters often let you sort by this parameter.
