Blackjack varies slightly according to the version, but the object of the game remains the same: to get as close to 21 as possible without going over or bust. The ace is used either as a one or 11 at the player's discretion.
The Play
The dealer will deal each player and himself one card face-up. He then places the second card face-up to the players and face-down to himself. Players may then request another card or hit, or they may stand. Once the players all stand, the dealer will turn his card face-up and continue to take cards until the value is 17 or more.
BlackJack Betting
Bettors must make initial wagers before the deal. Players can create additional bets during the game, as explained below, including side bets like 21+3 based on the player’s two cards and the dealer’s face-up card.
Splitting pairs
If the player is dealt a pair with his first two cards, he may decide to split. That is to treat each of the cards as a separate hand. The original wager remains with the first card and an equivalent amount is put on the second card.
Doubling down
If the value of the first two cards dealt is nine, 10, or 11, the player may choose to double down. The player doubles his bet. The dealer deals one more card face-down. The card remains face-down until settlement at the end of the hand.
Insurance
If the dealer's face-up card is an ace, players may make a side bet of up to half their original wager that the face-down card is a 10. This side bet pays out at 2-1, ensuring the player against losing their initial stake.
Settlement
If a player goes bust (over 21), the dealer collects the bet. If the dealer gets a natural (21 in the first two cards dealt), he collects the chips of all players who do not have a natural. If the dealer goes bust, all players receive their payout on bets that stand at less than 21.
If the dealer has less than 21, he will pay out any players with a higher total than his but less than 21. In the case of a tie, no chips change hands.
