RTP explained: How Return to Player works in online casinos

Return to Player (RTP) is a statistical average representing the percentage of total wagers a casino game returns to players over a vast number of rounds. For example, a game with a 96% RTP theoretically returns R$96 for every R$100 wagered across millions of simulated and real rounds. This figure is a long-term mathematical average and does not guarantee specific outcomes for individual sessions.

Casino games utilize a Random Number Generator (RNG) to ensure each round is independent. The complement to RTP is the house edge, which is the percentage the operator retains on average.

In Brazil, the Secretariat of Prizes and Betting (SPA/MF) under the Ministry of Finance requires licensed operators to disclose the RTP of each game visibly to bettors. This information is typically found within game menus or rule sections. Licensed platforms in Brazil often use certified providers, such as BMM Testlabs, to ensure RTP values are clearly declared and audited.
