I think, there is no difference first, second or third game, if you are lucky enough at that day, you win, that's all.
Well, I think the second and the first day don't really matter but the first day does. At least it matters more to casinos owners. You know what the say; 'first impression or experience matters' this is the phenomenon casinos owners use to attract their players. If first timer players win, there is a huge chances they will try to play again another day unlike first time players who loses on the first day.
