These are statistics to give players a rough idea of how likely they are to win when playing at certain casinos. Usually expressed as a percentage, such as 96.07%, this means that out of all the money wagered at this casino or on a particular game, 96.07% of that amount was returned back to players. In short, the higher this percentage is, the more likely you are to win. In addition, the fact that the casino displays these figures are in an effort to be more transparent, which in turn makes the casino that much more trustworthy and credible.
