4 5 6 or L R C is a game of pure luck and of those who have none. There is no way to increase your own odds of winning any more than the people all around you. The only way to get an edge in this game is to be playing with more than one person betting from the same money that you are. That makes it so you are both more likely to win but then you will get less because you must split the winnings. My advice is to just play when you feel lucky.
