I think there is a code and algorithm for every strategy we used in gambling games. If the casinos notice that we are employing a pattern or method to play their games against them, they won't let us keep winning. Since you've been successful with it recently, no method would continue to work for very long. Also, occasionally this may results in account banning. Therefore, if you won a good amount of cash, you should stop playing and comeback on the other day.
There is no code and algorithm for every strategy because the casino will hold back the code and algorithm we use so we can't win. But if you can win, it's because your luck came at the right time and helped you. And be careful if you have won using that strategy because that strategy might not work to be used again so we have to change the strategy and look for a suitable strategy. And I agree with stopping playing after winning a lot of money.
