I want to tell you that everyone have it on strategies of operational depending what you have in mind so I believe that this particular casino you most have a strategies before you could win it. But I'm sorry if my response is not working in accordance of what you have said here already
If you are trying to say that specific strategies work for specific casinos, you are completely wrong since no strategy works against any casino in the long-term because of the house edge factor.
People just think that some strategies work in the long-term because of winning with them several times, but that's a fallacy.
Do casinos on all different sites have to use different techniques too, sometimes it's the location and luck factor that can make us win the casino, not just technique, but how to play we can also bring luck, because everyone has different ways of playing, so the point is just it all comes back to us how to bring the game to victory..
