I have a feeling that the game script is created with the code to adjust to the players' strategy. We can also observe this thing happen on Dice. After using the strategy again and again, it will somehow stop functioning after some time.
There's really a code and algorithm for that.
The casinos won't allow us to win continually if they've detected that we're using some pattern or strategy against the games that we're playing on them.
That's why no strategy would work for long if you've been winning on it lately.
This is really and many casinos will keep doing that. Some casinos do not care if you win or not, what do really care about is how to make money money and pay their staffs.
If they detected that a gambler I'll s using a particular strategy to make more money, if it is a mere casino they can ban the gambler to limit the way he take money from them.
this is why it is always good to play on top and reputable casinos where payment is not a problem. you can already find them in this forum where they can afford to pay huge winnings without delay and hassle.
