All casino games have a certain house edge, which means the casino always has an advantage. You can, however, get lucky and hit a win despite the unfavorable odds.
That said, if you keep playing, you are much more likely to end up with a loss than with a profit. If you manage to win, we advise you to withdraw your money, because you will certainly lose if you keep wagering your money over and over again.
We have seen many players who managed to win tens of thousands of euros and then gradually lost all of it during the next few days or weeks (or even faster) because they kept playing and didn’t withdraw their winnings. That’s why we recommend players to be smarter than that and take their winnings if they get lucky and win. And it always helps to play in reputable online casinos.
