Strategy doesn't work in a luck based game. In a skill based game, you also need to be lucky for you to win your bet. It's a norm that gamblers will try their possible best to come with various strategies that they feel will work for them.
No amount of strategies would save the day in most of the games in casino bettings, we should just know and admit that the house is the one cutting the shot here, you win when they want you to win. Even if your suppose-winning strategy worked for a while, it can't be long before it would start disappointing you. That time it worked might also be the time the house wanted you to win, which most people mistake for a working strategy. I only respect strategies in sports betting.
