Return to Player
The Return to Player, or RTP, within any game is the expected percentage of stakes a specific game will return to the player over a period of time.
However, it is important to realise the % RTP is an average achieved over a significant number of game plays and not each time the game is played.
The average % RTP is typically measured over one million games played or greater.
For example, if a game displays an 85% RTP, it is not expected the player would win an average of £0.85 for every £1 staked during a playing session.
The RTP can vary widely in either direction due to statistical variance and differs from game to game.
Volatility
Volatility, often called variance or dispersion, is provided by the Game Suppliers. This is used to let players know how often they can expect the slot to pay out, and how big they can expect that payout will be.
A slot with low volatility will award players with frequent wins for low to mid-sized amounts, while a slot with high volatility will provide players with much larger wins at a more irregular pace.
