Jetbull Casino has a nice little page on their site called Casino RTP where they list the theoretical return to player (RTP) for most of their games.
You will on this page find the RTP for well over 800 games from NetEnt, Microgaming, EGT, NYX Gaming (NextGen, Thunderkick etc), Play’n GO, iSoftBet and Betsoft.
You can easily sort the numbers as you wish, for example high to low, alphabetically after game name or in groups based on vendor/manufacturer.
The return to player percentage indicates how much a game will theoretically pay out to players over a very long time.
It is set by the manufacturer and can normally not be changed by the casino, so for example NetEnt’s Blood Suckers will theoretically pay out 98% back to players regardless of whether you play it at Jetbull or somewhere else.
The higher the return to player percentage the better for the players.
That being said – whether a game has a RTP of for example 96% or 95% does not matter much in the short term.
Our opinion is that anything above 95% is good and what you should expect when playing online.
