What is a Payout Percentage in a Casino?

A payout percentage, also known as Return to Player (RTP), is a measurement that comes up a lot in the online gambling world. It represents the amount of money a casino game returns to players on average and over an extended period of time.

💡 For example, if you play a slot with a 98% RTP, you can expect a return of €98 for every €100 wagered, theoretically. This average is calculated across all players, so sometimes you can come away with a lot more and sometimes a lot less.

How is RTP Determined

These percentages are calculated through testing by independent 3rd party organizations like eCOGRA and iTech Labs. These institutions are responsible for conducting audits of casino games to ensure fairness and transparency. Simulations that mimic real-world play are run, to ensure the random number generator (RNG) algorithms are legitimate and cannot be rigged. This guarantees that the RTP figures advertised by online casinos are accurate and reliable.

Games with higher RTP rates have a greater potential to provide the player with chances of winning. Again, this is purely based on averages. However, it still remains a key factor when choosing where to play. This guide will delve into the best payout online casinos, helping you make informed decisions for your gaming needs.
