All gaming machines or slots are required to display the percentage of the Return to Player (RTP) figure, which represents the odds of winning. To arrive at the RTP percentage figure, an average of numerous games played is calculated. Usually between 10,000 and 100,000 games, depending on the category of the machine.
As an example, if the RTP is 85%, gamers should not (averagely) expect to win 85 cents of every $1 they stake in every playing session. Online gaming slots should equally make their return-to-player ratio clear to their players and gamers. The higher the RTP, the higher the winning odds.
