Blackjack Switch Rules: Two Hands, the Card Swap and the Dealer 22

Blackjack Switch gives you two hands at once and one unusual power: after you see both, you may swap the second card of one hand with the second card of the other. The game pays for that power in two ways. A natural blackjack pays only 1 to 1, and a dealer 22 pushes most of your hands instead of busting. This page explains how the swap works, what each rule takes from you or gives you, and how a round plays. It prints no house edge, because none has been calculated for this game.

How Blackjack Switch Works, Step by Step

The regulator texts describe the round in the same order, and the steps follow them. Where the texts differ, a later section says so.

1. Two equal bets#

Before any card is dealt you place two bets of the same size, one on each of two betting spots. Each bet belongs to one hand. Every regulator text requires the two to be equal. Optional side wagers exist in the documents, but this page covers none of them.

2. Two hands for you, one for the dealer#

The dealer gives you two hands of two cards each and takes a starting hand of their own. You see all four of your cards before you decide anything.

3. Insurance, if it is offered#

When the dealer shows an ace, insurance is offered, and the Washington rules say you may take it on either hand or on both. In the Massachusetts rules, insurance is placed before anyone is asked about the swap, so you decide on insurance first.

4. The swap#

Now comes the decision the game is named for. You may switch the second card of your first hand with the second card of your second hand. The first cards stay where they are, and only the second cards trade places. The Massachusetts text calls it "a player's one-time option", and the dealer asks it in one line, for example "15 or switch?". You may undo a swap, but only until another card has been dealt to either of your hands or to the dealer.

5. Play each hand as usual#

After the swap decision, each hand is played by ordinary blackjack rules. You can hit, stand, double and split. The Washington and Nevada texts say splitting, doubling, and doubling after a split are all allowed even after a switch. The hands are played one after the other, first hand first.

6. The dealer finishes and hands are settled#

The dealer draws until reaching a hard 17, or a hard or soft 18 or better, which means the dealer draws on a soft 17 in the New Jersey and Massachusetts texts. Washington lists standing on soft 17 as one version of the game. Each of your two hands is then compared with the dealer's hand as its own bet.

Swap the Second Cards: See Both Hands Change

As dealt: 16 and 19. A 16 and a 19. The 16 is the hand nobody wants against a strong dealer card. After the swap: 20 and 15. The king moves to the first hand and the six to the second: a 20 and a 15. One total went up by four, the other down by four.

Hand 1 as dealt: 10♠ and 6♥. Hand 2 as dealt: 9♦ and K♠.

Illustration only: cards are given, not dealt at random, and no chance or advice is attached to them.

The totals in the visualiser are simple sums of the cards shown. They say nothing about which choice is better.

Blackjack Switch Rules That Change the Game

Three rules separate Switch from ordinary blackjack. Each takes something back for the freedom the swap gives.

Naturals pay 1 to 1#

A blackjack, an ace with a ten-value card as the first two cards, pays even money. The Washington and Nevada texts say "Blackjacks pay even money". Ordinary blackjack pays more for the same hand. Washington adds that, depending on the version, blackjacks may be paid automatically.

The dealer 22 push#

If the dealer's hand reaches exactly 22, your hands that have not busted do not win. They push, which means your bet is returned. The Washington text says a dealer total of 22 "will push all non-bust player hands". In ordinary blackjack a dealer 22 is a bust and pays every hand still standing.

A natural is the exception. The Massachusetts text says a blackjack you keep without switching still wins against a dealer 22.

A switched 21 is not a blackjack#

If the swap gives you an ace and a ten-value card, you have 21 but not a blackjack. The New Jersey and Massachusetts texts define it that way, and so do Washington's versions 2, 3 and 4. It is paid as an ordinary winning 21, at 1 to 1. Washington's version 1 treats a switched blackjack as a real one and offers the swap before the dealer checks the hole card.

Where the Regulator Rules Disagree

Blackjack Switch is not one fixed game. The texts settle these points differently.

PointWhat the documents say
DecksSix or eight (New Jersey and Massachusetts)
Dealer on soft 17Hits in Washington versions 1 to 3 and the New Jersey and Massachusetts drawing rule; stands in Washington version 4
Switched 21 against a dealer blackjackLoses (Pennsylvania, Washington versions 2 to 4); in Massachusetts only a 21 of more than two cards loses to a dealer blackjack, so a switched two-card 21 pushes
Natural against a naturalPushes in most versions; Washington version 3 pays the player even money
SplitsThe reference set allows one split; a Massachusetts casino may allow up to three
SurrenderA licensee option in New Jersey and Massachusetts; not mentioned in Washington, Nevada and Pennsylvania
Dealer hole cardDealt after the players finish in the Massachusetts text, or checked earlier where the casino uses a card reader

The play table on this page follows one reference set: six decks, the dealer hitting soft 17, a switched 21 that loses to a dealer blackjack, and two hands per split. The page says which value is which whenever it matters.

What Each Rule Gives You and Takes Away

The documents list rules. They do not say what any rule is worth, so this section reasons in words and prints no number.

The swap gives you a second look. You see two hands before you play either, and you can always decline. That freedom is worth something to you.

The 1 to 1 natural takes some of it back. Every natural you are dealt is paid less than ordinary blackjack pays it.

The dealer 22 push takes back more. A dealer who would have busted on 22 now returns your bet instead of paying it, and a bust is how a weak hand of yours normally gets paid.

Small rules pull both ways. Doubling after a split and surrender, where allowed, help you. A switched 21 that loses to a dealer blackjack hurts you, and a version where it pushes hurts less. The size of each move is not published here.

How Your Decisions Change

You still hit, stand, double and split, on the same ideas as ordinary blackjack. The swap adds one decision before those, and it changes the rest in two ways.

First, a swap moves value between your hands and does not create any. A 20 and a 15 hold the same four cards as a 16 and a 19. The question is which split of that value suits the dealer's card, and the same swap can help in one deal and hurt in another.

Second, later decisions use the new hands. A swap can turn two ordinary hands into a pair to split or an 11 to double, as in the third example in the visualiser. It can also break a natural: an unswapped ace and ten is a blackjack, and the same cards after a swap are not.

This page publishes no chart of when to swap. That needs a calculation that has not been done for this game, and a guess would pass for authority. The visualiser shows the totals you hold now and the totals you would hold after the swap, which is what the rules let you weigh.

Worked Hands

Each hand carries a bet of 10, so 20 is at risk. The cards show the rules, not what usually happens.

Keeping a natural against a dealer 22#

Your first hand is an ace and a king, your second a nine and a seven: a natural and a 16. You keep both. The dealer draws to 22. The natural still wins and pays 10. The 16 pushes, where a dealer bust would have paid it in ordinary blackjack. Net: plus 10.

A swap that helps#

Your hands are a ten and a six (16) and a nine and a king (19). You swap the six and the king. The first hand is now a ten and a king for 20, the second a nine and a six for 15. A weak hand became a strong one, and the other hand gave up some strength. That trade is what the game is built around.

A swap that hurts#

You hold an ace and a five, and a nine and a king. Swapping gives an ace and a king, which is 21 but not a natural, and a nine and a five for 14. Against a dealer blackjack the switched 21 loses in most texts. Keeping a soft 16 and a 19 may have been the calmer choice. No calculation is shown, so read this as a consequence and not as a ruling.

Play Blackjack Switch with Play Money

The table below deals Blackjack Switch with play money. One bet is placed on both hands. After the deal the buttons read Swap and Keep, and then you play each hand. A natural pays 1 to 1 and a dealer 22 pushes. Hints are off: the chip says "Not computed for this game". Nothing is wagered and nothing can be won.

Real-money Switch is licensed only where a regulator allows it. This site names no venues and no operators, so ask your local gaming regulator what is offered near you. If play ever stops being fun, the responsible play page lists where to find help.

Why No House Edge Is Published for Blackjack Switch

Other game pages here print a house edge from an exact calculation of every decision. Blackjack Switch has none. The swap ties two hands together, so the right answer for one depends on the other hand and on the dealer card at once. That calculation has not been built, and a figure from another site would not have been checked here.

So the page prints no number, and none to hint at a comparison. When a calculation exists, the number will be added with what it covers. The house edge page shows which games have a figure today, and Free Bet Blackjack also has a dealer 22 push.

Where the Blackjack Switch Rules Come From

The rules come from New Jersey, Massachusetts (rules dated 8 October 2020), Pennsylvania, Washington State and Nevada regulator documents. The methodology page explains how they are read, and the sources page lists them all.

Questions

Frequently asked questions

What is Blackjack Switch?

Blackjack Switch is a blackjack variant in which you play two hands and may swap the second card of one with the second card of the other. In return the natural pays 1 to 1 and a dealer 22 pushes most hands. Every card is dealt by the same rules as ordinary blackjack, with the switch as one extra decision.

How does the switch work?

After you see your two hands, you may exchange their second cards. The first cards stay put. You get one switch per round, and Massachusetts lets you undo it until another card has been dealt. After that, each hand plays by the usual rules, and you may split or double even after a switch.

What happens when the dealer gets 22?

Every player hand that has not busted pushes and the bet is returned. That is the biggest change from ordinary blackjack, where a dealer 22 is a bust and pays the table. A natural you kept without switching is the exception, and it still wins against a dealer 22 in the Massachusetts text.

Does a natural blackjack pay 3 to 2 in Switch?

No. The regulator texts say a blackjack pays even money, 1 to 1. This is one of the rules that pays for the swap. A blackjack made by switching is not treated as a blackjack at all in most of the texts, but as an ordinary 21.

Is a switched 21 a blackjack?

Usually not. New Jersey, Massachusetts, Pennsylvania and Washington versions 2 to 4 treat it as a plain 21. Washington's version 1 counts a switched ace and ten as a blackjack. Against a dealer blackjack, most texts say the switched 21 loses, while the Massachusetts wording makes it a push.

Can I split or double after switching?

Yes. The Washington and Nevada texts say splitting, doubling, and doubling after a split are allowed even after a switch. A swap can even create a pair to split or an 11 to double. Split aces receive one card each in the Massachusetts text.

Do I have to bet on both hands?

Yes. You must place two equal bets, one on each hand, before any card is dealt. Each hand is then settled as its own bet against the dealer, so you can win on one hand and lose on the other. The equal-bet requirement appears in every regulator text on file.

What is the house edge of Blackjack Switch?

No house edge is published on this site for Blackjack Switch. The swap decision ties both hands together and no exact calculation has been built for it. Numbers found elsewhere have not been checked here, so the page prints none rather than borrow one.

How many decks does Blackjack Switch use?

New Jersey and Massachusetts allow six or eight decks. Washington's base blackjack rules allow up to eight decks. The play table on this page uses six decks, and the number is one of the points a casino can choose, so check the sign at the table before you sit.

Is there a strategy chart for Blackjack Switch?

Not on this page. A chart needs a calculation for the swap decision, and none has been built. The table says "Not computed for this game" if you ask for a hint. What the page can show is how the swap moves value between your two hands.
