RTP is a long-run measure.

Return to player describes a theoretical long-run return under a game’s mathematical model. It is not a prediction for an individual session or a guarantee that a player will recover a particular share of their stake.

A game can be available in different RTP configurations. Check the rules displayed by the operator for the particular version you open. A figure from another website may describe a different configuration.

Volatility describes how results vary, rather than whether a game is about to pay. Neither RTP nor volatility tells you when the next win will occur.
