Blackjack Variants and Versions
Blackjack has spread across the world and evolved into many forms over centuries of play. Each version brings its own table rules and optional side bets, influencing 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 looks at a selection of well-known variations.
European Blackjack
European Blackjack keeps the familiar challenge of playing against the dealer: make a hand worth 21, or as close as possible, without going over. Its main goal resembles that of other blackjack games, but its dealing and player-action rules give it a distinct style.
This version is included in online casino game selections. Players who know basic blackjack may enjoy exploring a different ruleset, but should check 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 dealer’s visible card is an ace, the player can take insurance for half the original wager. The insurance bet is settled when the hand ends.
After deciding whether to insure, the player takes their turn. Doubling is limited to hard totals of 9, 10 or 11. Any pair may be split except two different cards worth 10; doubling after a split is not allowed. Aces may be split, and players may hit 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 one visible card. An Ace as the upcard may prompt an insurance offer. Insurance is settled once the hand ends, since the dealer cannot take a second card until the player has completed their decisions.
If the player busts, the dealer generally does not need to draw again. Insurance is the exception: the dealer takes a second card to check for a natural blackjack, and a winning insurance wager is paid.

Vegas Strip Blackjack
Named after Las Vegas’s famous casino district, Vegas Strip Blackjack is a popular format found in land-based and online casinos. Table rules can differ in small but important ways, so check the casino’s posted rules before playing.
The goal 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 by beating the dealer while keeping your total within the limit.
Vegas Strip Blackjack Rules
This version uses four decks. Cards are dealt in this order: one face-up card to you, one face-up card to the dealer, your second card face up, then the dealer’s 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 bet wins.
The dealer also checks for blackjack when showing a card worth 10. In this case, insurance is not offered. If the dealer has blackjack, your wager loses.
If the dealer does not have blackjack, it is your turn. You may double on any first two cards, including after splitting. Pairs may be split up to three times, making as many as four hands. Aces may be split once, with one card dealt to each resulting hand. An ace paired with a 10-valued card after a split makes 21, but is not a natural blackjack.
Vegas Strip Blackjack: Dealer Rules
The dealer stands on every total of 17, both soft 17 and hard 17. If the dealer busts, the player wins regardless of their own total. If the dealer remains in play, the hands are compared by their distance from 21. Equal totals are a Push, or tie, and the original wager is returned.

Double Exposure Blackjack
Double Exposure changes the usual information balance: both of the dealer’s cards are dealt face up, which is why the game is also known as Face Up 21. Seeing the full dealer hand can help players, so other rules are adjusted in the house’s favour. The result is a familiar blackjack contest with different trade-offs.
The format is described as offered by many online casinos and land-based casinos in the US and Asia. As in other blackjack games, the player aims to beat the dealer with a total of 21 or a hand closer to 21, or to win if the dealer busts.
Double Exposure Blackjack Rules
This game uses 8 decks. Each round starts with two face-up cards for the player and two for the dealer. Players may double down 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 carries risk, 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 chance of improving your hand against the risk of drawing a worse card.
The dealer’s exposed hand is balanced by even-money payouts on all winning hands. This includes a natural blackjack, which also pays 1:1.
Double Exposure Blackjack: Dealer Rules
The dealer hits soft 17 and stands on hard 17. The dealer wins ties except when the tied hands are blackjack. If both hands total 21, the player wins and is paid 1:1.
Strategy Tips
When the dealer’s total is hard 17, or 18 whether soft or hard, the dealer must stand. To try to beat that total, you need to draw, while keeping in mind that a card could also bust your hand.
A dealer total of 12, 13, 14, 15 or 16 calls for another card, so the dealer may bust. If drawing could also bust your hand—when your total is 12 or higher—standing avoids that immediate risk and leaves the dealer to finish their hand.
Perfect Pairs Blackjack
Perfect Pairs adds a separate wager to the regular blackjack game. The side bet wins when the player’s first two cards form one of the qualifying pairs. The game has been popular in casinos in London and Macau, with interest also noted among Australian, European and Asian players.
Online versions have been associated with games from Microgaming, Playtech, NetEnt and other providers. The game has been described as growing in popularity, although each casino’s selection depends on its own offering.
Perfect Pairs Rules
Perfect Pairs may use Vegas Strip Blackjack or European Blackjack rules, with the side wager added. The game can use 2 to 8 decks. In principle, the side bet can also be offered with other blackjack variants without changing their underlying 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 may differ in size from the regular blackjack bet, subject to the table’s minimum and maximum limits.
The Perfect Pairs wager is settled as soon as the first cards are dealt. Only after any payout is made can the usual actions—Hit, Split or Double Down—begin.
Pair Categories
Three types of pairs may qualify for a payout:
- Perfect Pair – two cards with the same rank and suit, such as two 9s of hearts or two Queens of Spades
- Colored Pair – two cards of the same rank and colour, such as a 9 of hearts and a 9 of diamonds
- Red/Black Pair – two cards of the same rank but different colours, such as a 10 of diamonds and a 10 of spades
Perfect Pairs Blackjack Odds
The following are odds often listed for standard Perfect Pairs Blackjack with 8 decks. Casinos may use different terms, so check the odds in force before placing a side bet.
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
The introduction of this blackjack variant in Nevada is dated to 1995, and it is described as a fast-growing favourite. Its brisk rounds create a lively, action-packed pace; the account also claims players have a better chance of winning.
Spanish 21 Origins
The game was created by a casino employee who wanted 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 Spain or Latin America, the game originated in the United States. The name refers to the “Spanish deck” used for play, which omits all natural 10s and has 48 cards.
How the House Edge Changes
In blackjack, 10-valued cards can influence the player’s chances against the dealer. Card counters consider a shoe rich in 10s—both natural and non-natural—favourable to the player and may increase their bets accordingly.
Removing natural 10s from the deck increases the house edge. Special rules and bonus payouts offset this effect; 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 the rules and house edge at a specific casino, Spanish 21 may be a better option for a player than that casino’s blackjack game. The comparison depends on the particular tables.
Spanish 21 Rules
- The game uses six or eight decks, each containing 48 cards: a 52-card pack with the four 10s 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 split again.
- 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 down, the player may surrender and lose only the original bet.
- The player may double down after any number of cards.
21 Bonus
A hand that reaches 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
In Spanish 21, a Super Bonus may be awarded if 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 terms can vary between casinos, so check the table rules before playing. At most casinos, splitting or doubling makes the player ineligible for the bonus.
Envy Bonus
When a player wins the Super Bonus, each other player at the table receives an Envy Bonus of $50.
Blackjack Surrender
Blackjack Surrender takes its name from the option to give up a hand after the initial deal. A player who surrenders forfeits half their wager and gets the other half back.
This format is popular in Europe and is offered by many European casinos and in the Best Online Casinos.
Blackjack Surrender Rules
In principle, surrender can be added to many blackjack formats. The other rules follow the selected variant, with surrender as an extra option.
For example, consider late surrender with these rules:
- Dealer hits on 16 or less 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 the dealer has it, the original wager loses and insurance pays 2:1.
If both the player and dealer have a natural blackjack, the main wager is a Push, while insurance pays 2:1.
If neither hand is a natural blackjack, the player may surrender before taking another action. Half the original wager is returned, and the other half is lost.
This is known as late surrender. Early surrender is another option, where the player acts before the dealer checks for a natural blackjack. It may also be available 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.
Benefits
In a blackjack game with late surrender, the rule reduces the house edge by about 0.07%. This gives the player better odds than in the same game without the option.
Potential Drawbacks
The chance to surrender can 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 after the American East Coast gambling centre where it originated. It is also offered in online casino selections, although rules can vary between games.
As with other blackjack versions, the player aims to beat the dealer. A total of 21 is the target; otherwise, get as close as possible without going over 21.
Atlantic City Blackjack Rules
The game uses 8 decks and allows surrender. After placing a wager, the player receives two face-up cards. The dealer gets one face-up card and one face-down hole card.
If the dealer shows an ace, the player can insure against a natural blackjack for half the original wager. A winning insurance bet pays 2:1. If the up card is worth 10, the dealer also checks for blackjack but does not offer insurance.
Once the dealer confirms they do not have blackjack, the player acts. Doubling is allowed on any two cards, including after splitting, but resplitting is not permitted. Split aces get one card each. If a split ace receives a 10-valued card, the hand totals 21 but is not a blackjack, so it does not qualify for the higher 3:2 payout.
Atlantic City Blackjack: Dealer Rules
After the player stands, the dealer plays. The dealer must hit on totals of 16 or lower and stand on 17, whether the hand is hard 17 or soft 17. A dealer bust wins the hand for the player, whatever the player’s total. If the dealer does not bust, 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, although some formats use one or two. This relatively recent variant 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 2:1
- Blackjack pays 3:2
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 the hand is unlikely to win, losing half your original wager.
If the dealer’s visible card is an ace, insurance is offered. Otherwise, your turn begins. You can stand on your total or hit for more cards, trying to improve your hand without going over 21.
If your first two cards make doubling appealing, you can double your original wager and receive one more card. You take that single card rather than continuing to draw.
If your first two cards form a pair, you can split them into two hands. Doubling is also allowed on split hands, except when the split hands are aces.
Once you have finished, the dealer draws a second card. On soft 17 or any lower total, the dealer keeps 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 rule, 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. Bets pay even money, and the goal is simply to beat the dealer without busting.
Blackjack Switch – you wager on two hands and can exchange cards between them after the initial deal. The dealer hits on Soft 17. An optional “Super Match” side bet pays for combinations in 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 three hands.
Double Attack Blackjack – the dealer’s first card is dealt face up before the player acts. The player may 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.
