Most of the players know that the casino holds some benefit in blackjack. This benefit or advantage is also known as house edge, and is usually less than 1% in many blackjack games, provided players play by following the optimal basic strategy under the game rules.

What is house edge? It’s nothing but an expression of how much on each bet the house can receive to win on average in the long run. Example: if the house edge is 1%, and if you place bets of $100 then the house edge will be $1 on all the best you make with the casino.

Make sure to know that house edge is based on how much you expect to lose expressed as some percentage on your first deposit made with the casino. This will not include extra wagers you make while playing the game, like splitting and doubling down.
