First things first: What is the difference between a gambling system and a gambling trick? Actually not much. I look at gambling systems as a more complicated type of approach to a game such as roulette. I think of a roulette trick as a shorter, simpler method of approaching a game. One requires a certain type of discipline to follow; the other is short and sweet and not very taxing.One of the most enjoyable of my roulette tricks is the utilization of a Big Number roulette strategy. This is a straight number strategy where you bet directly on the chosen number or numbers.
