You can't beat the game, the more you play the more the winning will be equal to the house edge and that is a loss for you.
Just at times I think how do people blindly think that they have a great chance to win the money and knowing the facts that it is not that easy to make money or win from gambling as house will always and need to have the edge to make money for them self and not to distribute free money to others.
Right you are that it's not easy. Sometimes lose quite a bit or just flatline.
