I always tell and advise my friends who are new to gambling to never look for a pattern in luck-based games because there is none even the ever-popular martingale is not a guarantee that you can find a pattern that will give you a continuous win.
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..
I told him that the house edge plays out and since this is luck based game what works now may not work tomorrow every day is a new session with new patterns
How about you have you at one time of your gambling experience experienced finding patterns that you think are effective and consistent only to find out later after several days that it's not working anymore..
And are you still looking for patterns that you think will work in the long run for you.
on a normal day when it comes to gambling it desire strategy because without strategy you can't get more winning in gambler, so I think your friend discovered a way out for him to get some winning but not knowing that while you got one pattern you shouldn't relie on one. But still look out for more strategies and patten the one you use today might not work in the next day, don't blame him and we all know that gambling is all about luck and getting the right pattern so that you can win.
