Frequently Asked Questions
Why do extreme volatility slots ruin bankrolls even with 96.5% RTP?
In extreme volatility slots (such as Nolimit City titles), over 35-45% of the theoretical return is concentrated in rare bonus hits (1 in 200+ spins) and astronomical multipliers. Without sufficient bankroll depth (e.g. 500-1000 base bets), players suffer gambler's ruin during normal dead-spin drawdowns before catching a high-multiplier event.
What is the Volatility Index (VI)?
The Volatility Index is defined as VI = Z * (σ / √N). It quantifies the width of the confidence interval around expected payout percentage for a specific spin count, allowing direct mathematical comparison between diverse slot architectures.
How many base bets should a bankroll contain for high volatility?
For low volatility slots, 150-200 base bets provides a <5% ruin probability for a 1,000-spin session. For extreme volatility, simulations show that at least 600-1,000 base bets are required to maintain a ruin probability below 15%.
