Hit frequency is the percentage of spins that produce any winning combination — including small wins below your stake. Low-volatility slots typically have hit frequencies above 30%; high-volatility slots can sit below 20%.
Hit frequency is independent of RTP. A slot with 96% RTP and 25% hit frequency feels very different from a slot with 96% RTP and 35% hit frequency. The first will have longer dry runs and bigger hits; the second will produce frequent small wins with less dramatic peaks.
Hit frequency is rarely advertised in marketing material. Studios that publish it (most don't) put it in the technical info screen. David Chen's slot reviews on SpinVerdict include it where verifiable.
Example usage
- Starburst ~30% hit frequency (low-vol)
- Mental 2 ~17% hit frequency (extreme)
