RTP vs volatility
RTP and volatility are the two numbers that define a slot's maths. They answer different questions — and you need both to judge a game.
Two different questions
RTP answers "how much comes back over the long run?" Volatility answers "how bumpy is the ride to get there?" A 96% low-volatility slot and a 96% high-volatility slot return the same over millions of spins but feel nothing alike in a real session.
How to read them together
For longer play on a small bankroll, favour a solid RTP with lower volatility. To chase a big win and you can absorb dry spells, a high-RTP, high-volatility game fits. The worst combination is low RTP and high volatility — a fast, unforgiving drain. Learn each in our RTP guide and volatility guide.
