Blackjack is a popular card game played in casinos. The main objective of a blackjack card game is to get the point as close to twenty-one as possible, but not exceeding it. The blackjack card game is mainly divided into casino blackjack and online blackjack. Both follow almost the same betting procedures and strategies. There are slight differences between the blackjack played in land based casinos and that in online casinos. The main difference is in the card counting strategy.Blackjack is played at a table and allows for up to seven players per game. The first step is to make a bet. If the game is played in a land based casino, chips are used for the bet. The desired amount of chips is placed in the bet area. If the game is online, the bet is made by the value of the chips. The value of face cards is 10 points. Aces can be either 1 or 11 in value. Other cards are represented by their number. The first game consists of two cards. The player automatically wins when these cards make a combination of any ten and an ace. The player can ask for additional card when the initial card combination is less than twenty-one. This is called hit. Refusing additional card is called stand. If a player gets a combination of more than twenty-one, he automatically loses. This is called bust. A player wins when the dealer automatically loses the game.The betting options in blackjack card games are insurance, surrender, early surrender, double down, even money and split. If the dealer shows an ace card, the player can choose an insurance option. The insurance wager can be up to half the bet amount. Players can double the wager amount up to the bet amount. If a player has two cards with equal value, he is allowed to select a splitting option. The player may select the surrender option by giving up half the amount to the dealer.Players generally prefer real space casinos. Real space casinos offer player incentives, free trips, free shows and perks. However, online blackjack card games are also popular and easy to learn. Online casinos offer bankroll bonuses as player incentives. The disadvantage of online blackjack is that it lacks the playing environment. The user has to confirm the license of the blackjack casino software before downloading it. He must also check customer support services, wagering requirements and payout percentages before going in for an online game.
