There is no sure way to get a win and there is no way to beat the house, however players only have a big chance of losing not winning, so when you chase a win then losing a large amount of money is a guarantee.
Gamblers accept a great chance of losing with the possibility of a big win bet that is also offered by the casino. It will be a dilemma if we collide these two facts because gamblers actually do not want a bigger loss. But in another reality, they want the offer of a big win given by the casino. To get it, what happens is taking the risk of losing money. To avoid losing more money, gamblers must understand the situation where gamblers can play, or must avoid the game.
