I have a friend who boasted that he had found a pattern where it allowed him to win 10 successive bets on Mine Sweeper, he used that pattern two successive days with success but unfortunately for him on the third day those patterns are not working anymore even on the 4th and fifth days, now he is back on the drawing board again..
When you are gambling and you have a particular strategy that is working for you and you are making money, don’t think it’s going to be forever or for a long time, just take advantage of the strategy and make your money. If it stops working, then you have to upgrade the strategy, but if you fully depend on a strategy and you fully depend on a strategy and it stops working, you will be disappointed and frustrated and might end up gambling even when you are not supposed to gamble, and you are going to lose more, so we should have it in mind that any strategy can stop working at any moment.
I have never seen any strategy that actually guarantees wins in gambling. The only working strategy has to deal with discipline, self-control and money management. These are the right gambling strategies. Nothing else works out for gamblers other than these methods. Because most times players fail to understand that using a trick on the casino could work for few times and stop. And most often it doesn't work. The moment a gambler begin to worry over his failed strategy be could start moving from method to another hoping on changes. Not realizing that what works for a player wouldn't for another. Hence, everyone should work on their playing strategies, maybe upgrade as you suggested.
