Blackjack Variants and Versions
Over centuries of play, blackjack has spread and evolved into many formats. Each version can bring its own table rules and optional side wagers, changing how a hand plays while keeping the familiar contest against the dealer. Online casinos may offer several rule sets under the blackjack name. This guide covers a selection of well-known variations.
European Blackjack
European Blackjack keeps the familiar goal of competing with the dealer: make 21, or get as close as possible without busting. Its basic objective is shared by many blackjack games, but its dealing and player-action rules give it a distinct style.
This format appears in online casino game selections. Players familiar with basic blackjack may enjoy trying a different ruleset, but should review the specific table rules before playing.
European Blackjack Rules
The game uses two standard decks. The player receives two face-up cards, while the dealer starts with one face-up card and no second card. If the visible card is an ace, the player can place insurance for half the original wager. The insurance result is settled after the hand ends.
After deciding whether to take insurance, the player acts. Doubling is limited to hard totals of 9, 10 or 11. Players can split any pair except two different cards worth 10; doubling after a split is not allowed. Aces can be split, and players can draw on split aces. Surrender is not available.
European Blackjack Dealer Rules
The dealer stands on all totals of 17, including soft 17 and hard 17. While the player acts, the dealer has just one card, and it stays face up. If that card is an ace, insurance is offered. The bet is settled after the hand, since the dealer cannot take another card until the player completes their decisions.
If the player busts, the dealer generally does not need to draw another card. Insurance is an exception: the dealer draws a second card to check for a natural blackjack, and a winning insurance wager is paid if the dealer has one.

Vegas Strip Blackjack
Named after Las Vegas’s famous casino district, Vegas Strip Blackjack is a popular format offered at land-based and online casinos. Table rules may vary in small but important ways, so check the casino’s posted rules before you play.
The objective is familiar from many blackjack versions: play against the dealer and try to make 21 or get closer to it without going over. You win if your hand beats the dealer’s without exceeding the limit.
Vegas Strip Blackjack Rules
This game uses four decks. The deal follows this order: you receive one face-up card, the dealer gets one face-up card, you receive a second face-up card, then the dealer receives a second card face down as the hole card.
If the dealer shows an ace, you can insure for half your original wager. The dealer checks the hole card for blackjack; if they have it, your original wager loses and the insurance wager wins.
The dealer also checks for blackjack when showing a 10-valued card. Insurance is not offered in this case, and dealer blackjack means your wager loses.
If the dealer does not have blackjack, it is your turn. You can double on any first two cards and double after splitting. Pairs can be split up to three times, for a maximum of four hands. Aces can be split only once, and each resulting hand receives one card. An ace paired with a 10-valued card after a split totals 21 but is not a natural blackjack.
Vegas Strip Blackjack Dealer Rules
The dealer must stand on any hand totaling 17, whether soft 17 or hard 17. If the dealer busts, you win even when your own total is low. If the dealer does not bust, the totals are compared to determine which is nearer to 21. Equal totals are a Push, or tie, and your original wager is returned.

Double Exposure Blackjack
Double Exposure changes the usual information balance by dealing both dealer cards face up; the game is therefore also called Face Up 21. Seeing the full dealer hand can benefit the player, so other rules are adjusted in the house’s favor. The result is a familiar blackjack contest with different trade-offs.
This format is described as offered by many online casinos and land-based casinos in the US and Asia. As in other blackjack games, the goal is to beat the dealer with 21 or a hand closer to 21, or to win if the dealer busts.
Double Exposure Blackjack Rules
The game uses 8 decks. Each round starts with two face-up cards for the player and two face-up cards for the dealer. Players can double on hard 9, 10 or 11, including after splitting. Split aces receive one card each.
Seeing both dealer cards can change the decision compared with regular blackjack. If the dealer has 20 and you have 18, hitting is risky, but drawing a 3 would bring you to 21 and win. Standing leaves your 18 below the dealer’s total. With both cards visible, you can weigh the possible improvement against the risk of drawing a worse card.
The dealer’s open hand is offset by even-money payouts on all winning hands, including a natural blackjack, which also pays 1-to-1.
Double Exposure Blackjack Dealer Rules
The dealer hits soft 17 and stands on hard 17. The dealer wins tied hands, except when both hands are blackjack. If both hands total 21, the player wins and is paid 1-to-1.
Strategy Tips
When the dealer shows a hard 17, or 18 whether soft or hard, they must stand. To try to beat that total, you need to draw, while keeping in mind that a draw could bust your hand.
The dealer must draw on 12, 13, 14, 15 or 16, so there is a chance they will bust. If drawing could also bust you—when your total is 12 or more—standing avoids that immediate risk and lets the dealer finish their hand.
Perfect Pairs Blackjack
Perfect Pairs adds a separate wager to the regular blackjack game. The side bet pays if the player’s first two cards form a qualifying pair. The format has been popular in casinos in London and Macau, and has also attracted interest among Australian, European and Asian players.
Online versions have been associated with games from Microgaming, Playtech, NetEnt and other providers. Its popularity has been described as increasing, although each casino’s actual game selection depends on its own offering.
Perfect Pairs Rules
Perfect Pairs can use Vegas Strip Blackjack or European Blackjack rules, with a side wager added. The game may use 2 to 8 decks. In principle, the side bet can also be added to other blackjack variations without changing their base rules.
The wager predicts whether the player’s first two cards will form a pair and must be placed before the deal. The table has two betting spots: one for the main blackjack wager and one marked “perfect pairs” for the side bet.
The side wager can be a different amount from the regular blackjack bet, subject to the table’s minimum and maximum limits.
The Perfect Pair wager is settled as soon as the first cards are dealt. The usual options—Hit, Split or Double Down—are available only after the side bet is settled.
Pair Categories
Three types of pairs may qualify for a payout:
- Perfect Pair – two cards of identical rank and suit, such as two 9’s of hearts or two Queens of Spades
- Colored Pair – two cards of the same rank and color, such as a 9 of hearts and a 9 of diamonds
- Red/Black Pair – two cards of the same rank but different colors, such as a 10 of diamonds and a 10 of spades
Perfect Pairs Blackjack Odds
These are commonly cited odds for standard Perfect Pairs Blackjack with 8 decks. Casinos may offer different terms, so check the applicable odds before making a side wager.
Pair Payout Number of Combinations Probability Perfect Pair 25:1 1456 1.6867% Colored Pair 12:1 1664 1.9277% Red/Black Pair 6:1 3328 3.8554% No Pair -1 79872 92.5301% Total 86320 100%
Some casinos pay 30:1 for a Perfect Pair and 15:1 for a Colored Pair. Payouts and odds differ by venue, so check the table information where you play.
Spanish 21
This blackjack variation was introduced in Nevada in 1995, and has been described as a fast-growing favorite. Its quicker rounds offer a lively, action-packed pace; it has also been claimed that players have a better chance of winning.
Spanish 21 Origins
The game was created by a casino employee looking for a faster, livelier blackjack format. Masque Publishing, based in Colorado, USA, later bought the game; the company is the sole issuer of licences for its use.
Similar unlicensed versions may be called Spanish Blackjack. In Australia, a modified ruleset became known as Australian Pontoon.
Despite a name that might suggest a connection to Spain or Latin America, the game originated in the United States. Its name refers to the “Spanish deck” used to play: all natural 10's are removed, leaving 48 cards in the deck.
House Edge Changes
In blackjack, 10-valued cards can affect a player’s prospects against the dealer. Card counters consider a shoe rich in 10’s, both natural and non-natural, favorable to the player and may raise their bets accordingly.
Removing the natural 10’s increases the house edge. Special rules and bonus payouts counterbalance this change; the stated house edge is 0.40% when the dealer stands on soft 17 and 0.42% when the dealer hits soft 17 but redoubling is allowed.
Depending on a casino’s rules and house edge, Spanish 21 may be a better option than its blackjack game for some players. The comparison depends on the specific tables being considered.
Spanish 21 Rules
- The game uses six or eight decks, each with 48 cards: a 52-card deck with the four 10's removed. Cards may be dealt from a shoe or a continuous shuffling machine (CSM).
- Any pair may be split, with no restrictions on splitting pairs; aces may also be split.
- Aces may be resplit.
- After splitting aces, the player may hit or double down.
- Doubling after a split is allowed.
- A player total of 21 beats a dealer total of 21.
- The player’s blackjack beats the dealer’s blackjack.
- Late Surrender is available.
- Double Down Rescue is available: after doubling, the player may surrender and lose only the original wager.
- The player may double down after any number of cards.
Bonus 21
A hand totaling 21 may qualify for a special bonus payout:
Cards Suit Payout 5 Cards Mixed Suit 3:2 6 Cards Mixed Suit 2:1 7 or More Cards Mixed Suit 3:1 6-7-8 Mixed Suit 3:2 6-7-8 Same Suit 2:1 6-7-8 Spades Only 3:1 7-7-7 Mixed Suit 3:2 7-7-7 Same Suit 2:1 7-7-7 Spades Only 3:1
Super Bonus
Spanish 21 may offer a Super Bonus when the player has 7-7-7 of one suit and the dealer draws a 7 of any suit.
Bets from $5 to $24 usually receive a $1000 Super Bonus; bets of $25 or more usually receive $5000.
Super Bonus schedules may vary between casinos, so review the table terms before playing. In most casinos, splitting or doubling makes the hand ineligible for the bonus.
Envy Bonus
If a player wins the Super Bonus, every other player at the table receives a $50 Envy Bonus.
Blackjack Surrender
Blackjack Surrender takes its name from an option that lets players give up a hand after the initial deal. Surrendering forfeits half the wager and returns the other half.
The format is popular in Europe and is offered by many European casinos and at the Best Online Casinos.
Blackjack Surrender Rules
The surrender option can, in principle, be added to many blackjack formats. The rest of the rules follow the chosen variation, with surrender added as another option.
For example, consider late surrender with these rules:
- The dealer hits on 16 or lower and stands on all 17s
- Resplitting is not allowed
- Doubling after a split is allowed
- Players cannot hit split aces
- An ace and a 10-valued card in a split hand do not count as a natural blackjack
- Insurance pays 2:1
How to Play
The player starts by placing a wager and receiving two cards. If the dealer’s up card is an ace, insurance is offered. With a 10-valued up card, the dealer checks for blackjack; if they have it, the original wager loses and insurance pays 2 to 1.
If both player and dealer have a natural blackjack, the main wager is a Push, while insurance pays 2 to 1.
If neither hand is a natural blackjack, the player may surrender before taking another action. Half the original wager is returned and half is lost.
This option is known as late surrender. In early surrender, the player acts before the dealer checks for a natural blackjack. Early surrender may also be offered in no-hole-card blackjack.
Early surrender was once standard at many Atlantic City casinos. It later disappeared from US casinos because it gives players a greater advantage than late surrender.
Advantages
Late surrender lowers the house edge by about 0.07% in a blackjack game. Compared with the same game without this option, that reduction improves the player’s chances.
Drawbacks
The option to surrender may tempt players to give up too many hands just because a loss seems possible. The stated optimal approach is to surrender only the weakest hands: even a small chance of winning the full wager may be better than automatically losing half.
Atlantic City Blackjack
Atlantic City Blackjack is a widely played format named for the American East Coast gambling destination where it originated. It is also found in online casino selections, though rules may differ from game to game.
As with other blackjack variations, the player aims to beat the dealer’s hand. A total of 21 is ideal; otherwise, try to get as close as possible without going over 21.
Atlantic City Blackjack Rules
The game is dealt from 8 decks and allows surrender. After placing a wager, the player receives two face-up cards. The dealer receives one face-up card and one face-down hole card.
If the dealer shows an ace, the player can take insurance against a natural blackjack for half the original wager. A winning insurance wager pays 2-to-1. If the dealer’s up card is worth 10, they also check for blackjack, but insurance is not offered.
After the dealer confirms they do not have blackjack, the player takes a turn. Doubling is allowed on any two cards, including after a split, but resplitting is not allowed. Split aces receive one card each. If a split ace gets a 10-valued card, the hand totals 21 but is not blackjack and does not qualify for the higher 3-to-2 payout.
Atlantic City Blackjack Dealer Rules
After the player stands, the dealer plays. The dealer must draw on totals of 16 or lower and stand on 17, whether the hand is hard 17 or soft 17. A dealer bust gives the player a win regardless of the player’s total. Otherwise, the hands are compared to see which is closer to 21.

Big Five Blackjack
Big Five is distinguished by its five-deck shoe. Blackjack is more often dealt from four, six or eight decks, while some formats use one or two. This relatively recent variation has also appeared in online casinos.
Big Five Blackjack Rules
- Uses five decks
- Dealer hits on soft 17
- No-hole-card game; the dealer does not peek
- Doubling down is allowed on all hands
- Doubling after a split is allowed
- Aces may be split
- Split aces receive only one additional card
- Early Surrender is allowed unless the dealer shows an ace
- Insurance pays 2-to-1
- Blackjack pays 3-to-2
How to Play Big Five Blackjack
After you place a wager, you receive two face-up cards and the dealer gets one face-up card. At this point, you may surrender if you think your hand is unlikely to win, forfeiting half your original wager.
If the dealer’s visible card is an ace, insurance is offered. Otherwise, your turn begins. You can stand or hit for more cards, trying to improve your hand without exceeding 21.
If your first two cards make doubling appealing, you can double your original wager and take one additional card. You must then stop drawing.
If your first two cards make a pair, you may split them into two hands. You can also double on split hands, except when the split cards are aces.
After you finish, the dealer takes a second card. On soft 17 or any lower total, the dealer continues drawing until reaching hard 17 or higher, or busting. If the dealer busts, you win regardless of your total.

Other Blackjack Variations
Dealer Stands on Hard 17 – under this ruleset, the dealer hits below 17, including on soft 17, where an ace counts as 11.
Dealer Stands on Soft 17 – the dealer stops drawing on any total of 17, including a soft hand with an ace.
21 Duel Blackjack – players cannot split, double down or take insurance. Wagers pay even money, and the only objective is to beat the dealer without busting.
Blackjack Switch – place wagers on two hands, then exchange cards between them after the opening deal. The dealer hits Soft 17. An optional “Super Match” side bet pays for combinations among your original four cards: a pair pays 1 to 1, three of a kind 5 to 1, two pairs 8 to 1 and four of a kind 40 to 1.
Pontoon – both of the dealer’s cards are face down. The game has its own terms: “Buy” means double, “Stick” means stand and “Twist” means hit. A Pontoon pays 2 to 1. Players may “Buy” after splitting and split up to a maximum of three hands.
Double Attack Blackjack – the dealer’s first card is dealt face up before the player acts. The player can then double the wager before receiving cards. Insurance pays 3 to 1. If the dealer shows 10 and checks for blackjack, a dealer blackjack forfeits the original wager but returns the Double Attack wager. Doubling is allowed on any first two cards and after splitting aces.
