The house has an advantage in blackjack because the house edge is always greater than 1%. This means that for every 100 hands played, the house will win on average 68 hands and lose on average 32 hands.
This means that over the long run, the house will come out ahead. .
One reason for this advantage is that casinos offer blackjack as a purely financial proposition. Casinos don’t care about winning or losing as much as they do about making money. This means that casinos will keep the house edge high in order to make more money overall.
In fact, casinos typically have a house edge of about 2.5% in blackjack.
Another reason for the house edge is that casinos have more information about player behavior than players do themselves. casinos can see which players are more likely to lose money and adjust their games accordingly.
For example, casinos might reduce the number of cards dealt to a player or increase the number of credits given to a player in order to make it more difficult for that player to win.
