RTP (Return to Player) vs Volatility (Variance)

What each means, how they relate, and when to use which.

RTP is the average a game returns over the long run; volatility is how far individual results swing around that average. Two 96% games can feel completely different: a low-volatility one pays small and often, a high-volatility one pays rarely but large. RTP is the mean, volatility is the spread.
