The ways to win is to know your limits have fun and don't be greedy with your current lose or win. Its was been always a struggle for every single person who plays a role in gambling but having no satisfaction will lead to exit in loss instead of winning.
I think when we are in long run win we will forget our limits and continue our play until we lose our winnings and capital this is most of the gambler's problem. we can't control our emotions when we are in profit or loss. those who can limit his winning and stop play when he reaches that amount he will walk home with a profit.
