Since blackjack is a skill-based game, if you apply a strategy throughout the course of the game, you have a very realistic chance of winning consistently and thus, making a profit. However, it should be noted that you can become a winner and turn a profit only over a long period of time. This means that you have to aim at smaller but more frequent profits rather than one big. Furthermore, it is a game which offers a positive expected return and a fairly low house edge.
