House do always wins but it would really be normal that they would really be keeping an eye on someone whose really do make out winnings or simply being profitable.Its really impossible that
they wont really checking out if there are some exploit or something that it is really against their terms but most of the time they arent proven out and just simply
there are people who are really that extremely lucky.
House oversees the system to improve or increase maintenance to prevent exploitation of the use of bugs for gambling wins, but if the gambler uses a normal strategy with several combinations of opportunities used then it does not mean 100% without defeat but the dominance of the potential to win is higher, so the point is that gamblers do not need to feel worry if the strategy will work and never engage in activities that violate rules.
