Volatility
The standard deviation of per-spin outcomes; how much bankroll swings during a session.
Also known as: variancedispersion
The shape of a slot’s payout distribution around its RTP. Low volatility means frequent small wins; high volatility means rare big wins.
Providers use a 5-tier scale (low, med-low, medium, med-high, high). RTP tells you the long-run return; volatility tells you the short-run shape.
Two slots at 96% RTP can look completely different over 500 spins if one is low-vol and the other high-vol. See the volatility guide.
