Theirs no game that doesn't have a primary way of playing it, what I know concerning games is that you most know and understand the primary ways of game, so I believe that each game have its methodology in which you apply in any of them, basically we learn how to bet a game, but for the aspect of slot game I think that I'm still learning how to play slot game, but you can understand it properly when you brought out time to learn its strategies, because what make people to see slot game as a difficult one is when they have not make out time to make research of the game.
You have to stop gambling by relying on the methodology in slot gambling, gamblers already know that slot gambling is regulated with a random winning system so never rely on any strategy to win except luck. I have observed every slot gambling session and I have not found a main strategy to win with the same methodology based on previous wins, we often win when we least expect it and rarely do we win in the main way in slot gambling. So be careful in choosing bets based on strategy because it is very unlikely that you can repeat your winnings with the same game strategy.
