What does the term RTP indicate in online slots?

RTP stands for Return to Player and denotes the theoretical percentage of total wagers a slot game will pay back to players over an exceptionally large number of spins. For example, a 97% RTP slot is set to return £97 for every £100 wagered in the long run. This figure is determined over millions of simulated rounds and does not forecast individual session outcomes.

Which provider provides the highest RTP slots at Otto Casino?

NetEnt and Microgaming always deliver the highest individual RTP figures at Otto Casino, with titles like Mega Joker reaching up to 99% and 1429 Uncharted Seas sitting at 98.6%.
