- Low
- Low/medium
- Medium/high
- High
Fundamentally, volatility is the key to determining the magnitude and frequency of payouts during gameplay in online slots. Low volatility is best for casual and extended spinning sessions, whereas high variance is suited to risk-takers with longer periods without wins, which can be immensely rewarding.
