The house edge, or casino advantage, in blackjack is the percentage of the bet that the house takes from the player. This is calculated by taking the ratio of the dealer’s profit (the difference between the amount won and the amount bet) to the player’s bet. In general, casinos prefer to have a house edge between 1.
5% and 2.5%, but it can be as high as 5%. .
There are a few factors that affect the house edge in blackjack: how often each hand is played, how tight or loose the rules are, how skilled the dealers are, and what type of table (strip or corner) the game is being played at. The house edge can also change depending on which players are playing against each other.
Theoretically, a casino could make money no matter what the house edge was; however, in reality, casinos prefer to have a slightly higher edge to help offset losses from players who lose more than they win.
