The house always wins in blackjack, which is why casinos are so profitable. The house edge is about 2.7%. This means that for every 100 hands played, the house will win about 72 hands and lose about 28.
In order for a player to have a fair chance of winning, they need to bet an amount that is at least equal to the house edge. For instance, if the house edge is 2.7%, then a player must bet at least 3.7% of their total bet in order to have a fair chance of winning.
