Play N Go licensed in Curacao, that should tell you enough. Put it this way after playing Play N Go for about 2 years now, my RTP for that time is 70.03 percent more than 20 points lower than my 2nd worst performance on a downloaded software. I called their office in Sweden as CS gave the usual line we just rent them. I questioned the legitimacy of the software by asking a question does your quoted RTP stand for playing one line as opposed to playing all lines - say 20. There was much confusion, transferred me to many people. At first gave one answer and said yes it makes no difference. Then put me on hold, another person came back and said no, I asked what is the RTP on such and such game for playing one line. I cant tell you that it's confidential , and then came on and said it made no difference our RTP stands as quoted. OK. So that made me feel confident -NOT What struck me as odd, on these browser based/flash software was how the RTP was always referred to as TRTP -theoretical Return To Player, . The coding that makes up a slot cant be theoretical. Either it's coded as such or it is not. This new TRTP seemed to be in use on Browerserbased/flash multiplatform casinos, but not for example on Viper downloaded microgaming or even RTG,old cryptogic software. With the new architectural platforms used by these software companies, that allow for fast bi directional transfer of Data, at speeds never seen in years past, it occurred to me that the central sever was doing more that dishing out a RNG like they do with conventional downloaded software. What they are doing is handing out results, calculated in miliseconds on the last result ofdata received. Hence the reference TRTP, and at no time can the casino or software ever be taken for a hit, like a max bet jackpot scenario, without it being covered beforehand. So in reality no more than a lottery terminal, or sometime referred to as a class 3 machine. What other alogorithm are in play -player profile, deposits withdrawls bet size etc is anyones guess. Technology and computing power has come along way since the early days of the 90's, and we the customer/punter have not kept up and are none the wiser. Ever realized why browser/flash based casinos are so fast at paying out now compared to the conventional downloaded casinos. They cant be hit.
