What Is Bonus Frequency in Slots?
Bonus frequency (also called «feature hit rate») is the statistical average number of spins required to trigger any bonus feature, such as free spins, respins, or a bonus game. For example, if a slot has a 1-in-120 bonus frequency, you can expect a feature roughly once every 120 spins (based on RNG math). This metric is not the same as the overall hit frequency (low pays) — it focuses exclusively on the premium bonus events.
Why Bonus Frequency Matters for Your Bankroll
- Predictability: Low bonus frequency slots (1 in 300+ spins) drain your balance before any big payout, requiring a larger bankroll.
- Entertainment value: Higher bonus frequency (1 in 80–100 spins) provides more action, free spins, and excitement per session.
- Risk management: Knowing the bonus cadence helps you set loss limits — if you know a bonus is due every 100 spins, you can plan a 200-spin session with two expected features.
Bonus Frequency vs. Slot Volatility: Key Differences
Volatility measures payout size distribution (wins are rare but large vs. frequent but small). Bonus frequency measures how often you enter feature rounds. A slot can be:
- High volatility + high bonus frequency (e.g., Bonanza — frequent but volatile features)
- Low volatility + low frequency (rare features, small regular wins)
Always check both metrics: a high bonus frequency does not guarantee big payouts if the feature’s average multiplier is low.
