RQ-21 Blackjack, a small tactical unmanned air system Black Jack Brigade, nickname of the U.S. 2nd Brigade Combat Team, 1st Cavalry Division Tupolev Tu-160 (NATO reporting name: Blackjack), a Russian bomber. 'Blackjack', an ace and a face card or ten, is the top scorer. Blackjack usually pays a bonus. Five cards adding to 21 or fewer is the next ranking hand. Apart from that, unbusted hands rank by total add-up. Hands below the dealer's hand lose unless the dealer goes over 21 (busts). Hands equal to the dealer's keep their chips.
Spanish 21 is a blackjack variant owned by Masque Publishing Inc., a gaming publishing company based in Colorado. Unlicensed, but equivalent, versions may be called Spanish blackjack. In Australia and Malaysia, an unlicensed version of the game, with no dealer hole card and significant rule differences, is played in casinos under the name 'Pontoon'. It was first introduced about 1995.[1]
Rules[edit]
Spanish 21 is played on a blackjack table with a custom layout and uses the following rules:
- The game is played with six or eight decks dealt from a shoe, or from a continuous shuffling machine (CSM). Spanish 21 is played with 48-card Spanish decks, although standard French suited 52-card decks are used with the 4 ten-spot cards removed. All cards have the same values as in blackjack.
- The dealer gets a hole card.
- Like traditional blackjack, the dealer hits on 16 and stands on 17. In some venues, the dealer hits on a soft 17 (abbreviated as H17), though most venues have the dealer stand on soft 17 (S17). Hitting soft 17 (H17) negatively impacts the player; that rule increased the house edge by 0.40%.
- Blackjack (a natural total of 21 on the first two cards) always wins, and is always paid 3:2 regardless of whether or not the dealer has a blackjack.
- Insurance is paid 2:1, just like in blackjack, despite the fact that there are four fewer ten-valued cards per deck. As 3 cards in 12 are worth ten, the chance of the dealer getting a blackjack when showing an Ace is only 25%. Therefore, for insurance to be an even bet, it would have to pay 3:1, not 2:1. The house edge on the insurance is 24.7%, one of the worst of any wager in a casino.
- Hitting, standing, and splitting all follow similar rules to blackjack. Doubling after splitting (DAS) is always permitted, and, in most venues, players are allowed to draw as many cards as they wish after splitting aces, or may double down after receiving second or subsequent cards.
- Players can split to a maximum of four hands, even on aces.
- In most venues, if the dealer does not have blackjack, players may surrender, and get half their bet back in exchange for relinquishing the right to play on. This type of surrender is known as a 'late surrender' (LS).
- Players can surrender after doubling (sometimes called forfeit, double-down rescue, or concede). The dealer takes the original bet, and the player retains the double portion of the bet. This is because the player is allowed to double down for less than the original bet.
- Once the initial two-card hands are dealt, if the dealer is showing an Ace or face card, he peeks underneath the hole card to check for a blackjack, before playing actually commences. If he has blackjack, all players automatically lose, unless they also have a blackjack (which, as mentioned above, automatically win 3:2).
- The player may double down on any total and on any number of cards.
- In some casinos, players may double double down, or redouble up to two times after doubling down. For example: The player bets one unit and is dealt 2-3, giving a hand total of 5; the dealer is showing a 6. The player doubles the first time and draws a 3. The hand total is now 8 and the total amount wagered is two units. The player doubles a second time and draws a 3. The hand total is now 11 and the total amount wagered is four units. When the player doubles a third time on 11, the total amount wagered will be eight units. Redoubling is a profoundly player-advantageous rule, when optimally executed.
- A total of 21 always wins for the player. It never pushes against the dealer's 21.
- A five-card 21 pays 3:2, a six-card 21 pays 2:1, and a 21 with seven or more cards pays 3:1. A 21 composed of 6-7-8 or 7-7-7 of mixed suits pays 3:2, of the same suit pays 2:1, and of spades pays 3:1. These bonus payouts apply even if the hand was the result of a split. However, doubling down negates these bonuses.
- A 'super bonus' of $1000 for bets under $25, and $5000 for bets of $25 and over, is paid on a suited 7-7-7 against any dealer 7. All other players at the table receive a $50 'envy bonus'. Splitting or doubling down negates the 'super bonus'.
The removal of the four tens in each deck gives roughly a 2% advantage to the dealer. The liberal rules of Spanish 21, though, do compensate for this. With optimal play, the house edge of a Spanish 21 table is lower than that of a blackjack table with the same rules on hitting or standing on soft 17.
The game also offers an optional 'Match the Dealer' side bet, which compares a player's cards with the dealer's upcard. Matching the rank of the dealer's card pays 4:1 on a six-deck game, and 3:1 on an eight-deck game, while a 'perfect match' of rank and suit pays 9:1 on six decks and 12:1 on eight decks. A player may win on both cards; (e.g. if a player has 8s 8c and the dealer has 8c as an upcard, the player will receive 3:1 on the rank match and 12:1 on the perfect match, paying out a total of 15:1.) While this side bet has a house edge of approximately 3%, significantly higher than the edge of the main game, it is one of the lowest house edges of any blackjack side bet.
House edge[edit]
The following tables list the Spanish 21 house edges for all rule sets found in North America.[2] (The figures were obtained from 10-billion hand simulations and have a standard error of 0.001%. The super bonus is averaged out to a 100:1 payout.) These charts assume that the player is using basic strategy. 'H17' means that the dealer hits soft seventeen, 'S17' means that the dealer stands on soft seventeen.
| Rules | Decks | House Edge |
|---|---|---|
| H17 | 6 | 0.78% |
| 8 | 0.80% | |
| S17 | 6 | 0.37% |
| 8 | 0.38% | |
| H17 with redoubling | 6 | 0.42% |
| 8 | 0.45% |
| Rule Changes | Change in House Edge |
|---|---|
| No surrender (H17) | 0.018% |
| No surrender (S17) | 0.006% |
| No draws on split Aces (H17 or S17) | 0.28% |
| No draws on split Aces (H17 with redoubling) | 0.29% |
| Natural after split pays 3:2 | –0.16% |
Match the Dealer[edit]
Match the Dealer is a side bet offered on most Spanish 21 games. The player wins the side bet if the rank of either or both of their initial two cards matches the rank of the dealer's up card. If the cards match in both rank and suit, the player wins a bigger payout. Some casinos offer a second Match the Dealer bet which wins when either or both of the player's initial two cards match the dealer's hole card. The payouts and the house edge vary depending on the number of decks in play as shown below.
| Number of Decks | Non-Suited Match | Double Non-Suited Match | Suited Match | Suited + Non-Suited Match | Double Suited Match | House Edge |
|---|---|---|---|---|---|---|
| 2 | 4:1 | 8:1 | 15:1 | 19:1 | NA | 3.63% |
| 4 | 4:1 | 8:1 | 10:1 | 14:1 | 20:1 | 3.20% |
| 5 | 3:1 | 6:1 | 13:1 | 16:1 | 26:1 | 3.53% |
| 6 | 4:1 | 8:1 | 9:1 | 13:1 | 18:1 | 3.06% |
| 8 | 3:1 | 6:1 | 12:1 | 15:1 | 24:1 | 2.99% |

Blackjack (Twenty-one, pontoon or Vingt-et-un) is a kind of card game which usually involves gambling. It is often played in casinos. There is a dealer, who deals cards from a special device called a 'dealer's shoe' or a 'shuffling machine'. The dealer has one to eight decks. When there are one or two decks, the dealer usually holds the decks instead of dealing from a shoe.
It is a 'dealer versus players game'. Each player has their own game against the dealer. Cards are dealt in succession, and bets placed for each hand. Players win if their cards add up to more than the dealer's hand to a limit of 21. Hands which add up to more than 21, called busted hands, lose. Face cards count as 10. Aces can count as one or eleven.
'Blackjack', an ace and a face card or ten, is the top scorer. Blackjack usually pays a bonus. Five cards adding to 21 or fewer is the next ranking hand. Apart from that, unbusted hands rank by total add-up. Hands below the dealer's hand lose unless the dealer goes over 21 (busts). Hands equal to the dealer's keep their chips. If both the player and dealer bust, the dealer wins.
Players have a choice whether or not to get extra cards. Stand means to get no more cards and hit means to ask for another card. To stand, wave your hand back and forth. To ask for another card, wave your hand toward you. You can ask for any number of cards unless you bust. The dealer has rules as to when he takes extra cards for himself (or herself). In the UK, the dealer must stand on 16.[1] These rules are set by the casino and cannot change after the game has started. In some states or countries, the rules are set by the government.[2][3]
There is some skill in blackjack, because the odds change as the cards are dealt. The critical information is the numbers of tens (including face cards) which have been dealt. This is because they are the common cause of 'busting' the dealer hand and because they are needed for a blackjack. Aces are also important because they are needed for a blackjack.[4] Keeping track of the cards is called 'card counting'. It is legal if done without a device like a computer. But, many casinos tell players to leave if they think are counting the cards.
History[change change source]
Over the years the origin of Blackjack, like many other games, has eluded researchers for a long time and which continues to be hotly debated to this day. Till date there has been no clear consensus, but most agree it probably originated in French casinos around 1700, where it was called Vingt-et-Unwhich, translated, means twenty-one. Most believe it was probably derived from the French card games, Chemin de Fer, and French Ferme, which were in vogue at that time. Another of its version was prevalent in Spain, which was called 'One and Thirty'. The basic rule of the Spanish version was to reach 31 with a minimum of three cards.A theory that's also doing the rounds is that Blackjack was an invention by the Romans. It is believed that Romans used to play this game with wooden blocks of different numerical values. This theory holds some weight as Romans loved gambling, but that by no means confirms the theory. Among the various versions of the game, 'Vingt-et-Un' or '21' continued to grow in popularity and reach. It gradually spread to North America thanks to French colonists and soon after it was played throughout the continent. The rules of Blackjack were then different from those of modern or contemporary Blackjack. Just to elaborate, in this form of Blackjack, only the dealer was permitted to double. Also, a betting round was there between each of the playing cards dealt.The game was still termed '21' when it gained popularity in Nevada in 1931 as the State first chose to make gambling legal. Its origin is disputed, but it is certainly related to several French and Italian gambling games. In Britain since World War I, the informal game has been called pontoon.[5][6] To draw more people to the game, some casinos then offered a special bet: A hand featuring either of the black jacks (the Jack of Spades or that of Clubs) plus the Ace of Spades would pay 10-to-1 odds on the lucky player's bet. Although casinos later discontinued this peculiar payout, the name 'blackjack' or 'black jack' remained, as the game is known today.Five of Clubs: 'Watson’s card'. The name has nothing to do with Sherlock Holmes but refers to a famous gambler who is supposed to have won £10,000 at Faro through his wager in connection with this card.Blackjack was not conceived by any one person at one definite point of time. On the contrary, blackjack has evolved over centuries; it continues to evolve and grow even today, thanks to the Internet. Fuelling its popularity the online casino industry has developed various versions of the game which has truly revolutionized it.Now a few reputed casino operators have started an innovative and far more enjoyable concept of this game: live blackjack game with real dealers. Live Blackjack is the most advanced way to play your favourite casino game right in the comfort of your home, without having to go a long way to a field-based casino.[7][8]

Blackjack example[change change source]
This is an example of a Blackjack game. Players are named by gambling chip colour: white, brown, blue and black.
The dealer has given two cards each to the four players who are betting. One of the dealer's two cards is face-up so all the players can see it (an Ace), and the other is face down.
- Black gets an Ace and 2 which is worth either 13 or 3, and asks for a hit and gets a King (worth 10) which takes black to 13; black hits again, gets 16 and decides to stand.
- Blue gets a King and Jack which are worth 20 together and of course chooses to stand. (Splitting a K and J may be possible in some games although it is unusual to split a 20 because it is such a high hand)
- Brown gets a 10 and 4, and asks for a hit, gets 2 which takes brown to 16. Another hit and they get a 10, which means they are bust at 26 and the dealer takes the chips. Normally the cards would be taken away immediately with the bet.
- White gets two 5s, so they double the bet and split the cards, the dealer gives them a 5 and a 7 for each. They ask for hits in both cases and get a 9 and 6, taking them to 21 and 16 respectively.
The dealer turns their card over and gets a 6, together with the Ace takes them to 17, and stands because the dealer must stand on 17. (In this case the dealer must stand on a 'soft' 17). Results:
- Black loses their chips because the dealer's 17 beats black's 16
- Blue is paid the same amount of chips they bet because blue's 20 beats the dealer's 17
- Brown has already lost their chips when they went bust
- White's 21 is paid at 2:1, which means that white receives double and a half the amount of chips white bet for one of the splits, however white loses the other half of chips bet on the 16 which is beaten by the dealer's 17. Most games do not pay 2:1 for a hand of 21 however. The strongest scoring 21 would be an ace card and any other 10-point card. You can actually get to 21 in many different ways, but the ace and 10-point card combination will beat those variations.
Variations[change change source]
- Base (American): with one dealer's open card and one hole card. With an open ace or a dozen (in some variations only with ace), the dealer looks at the hidden card and, if the blackjack dealer, the game ends.
- European: the dealer takes the second card after all players finish the set. In the case of a blackjack dealer, the players are returned all additional bets (except for 'insurance'),
- On the basis of Blackjack, numerous versions have been created, with their own names such as Blackjack in the open (Double Exposure), 3-Card Blackjack, Blackjack Switch, Spanish 21, Caribbean 21, Super Fan 21, Pontoon, etc.[1]
