There are certain differences between the European and American game of blackjack that can serve as a guide to the choice of the online casino where we want to play.
In the case of the European blackjack game the dealer gives out one card after having distributed the first round of cards to all the players, then each player performs their bets. Once they have all made their bets the dealer completes its game. In the case of obtaining a blackjack, all hands below are lost, including openings and doubles.
By contrast, in the American way of blackjak game, the dealer gives out two cards instead of one, the first at the end of a round of giving out to the players, and the second when all they have received their second. The dealer must discover one of their cards and the other remains hidden, that card is called to the English term “Hole Card”. If the visible card is a 10 or Ace, the casino has a duty to offer the insurance hand. In this way the game does neither open nor loose additional cards, or bends, or open pairs. And in the event that the house has blackjack it only losses the original bet.
In the case of European blackjack game, when a player opens or doubles when the dealer has a 10 and then achieves a blackjack, the player loses all their bets.
Also there is a variation in the European blackjack game online casinos in which if the dealer gets a blackjack and players doubled or opened their bets, just loses the original bet and recovers the remaining bets. In this way the game is a little more about its American version.
