How Blackjack Switch differs from classic blackjack

  • Two hands, one bet each: you bet the same amount on two hands, and both are dealt face up.
  • The switch: before you play them, you may swap the second cards of your two hands once. Press “Switch” or “Keep”: hands (a, b) and (c, d) become (a, d) and (c, b).
  • Blackjack pays 1:1, and only an ace and a ten dealt together count. An ace and a ten made by switching are an ordinary 21.
  • Dealer 22 pushes: when the dealer finishes on exactly 22, every hand still in play is a push. Busted hands still lose; a dealt blackjack is still paid.
  • The dealer checks for blackjack before the switch: if she has it, each hand loses one bet and a dealt blackjack pushes. No insurance, no surrender. This table: 6 decks, dealer hits soft 17, double on any two cards (also after the switch and after a split), split up to 4 hands from each of your two hands, split aces get one card.

The switchYou may swap the second card of hand 1 with the second card of hand 2, once, before you play. Putting the two first cards together is not allowed.
Blackjack pays 1:1Only an ace and a ten dealt together count as blackjack. An ace and a ten made by switching are an ordinary 21.
Dealer 22 pushesIf the dealer finishes on exactly 22, every hand that has not busted is a push. A dealt blackjack still wins.

House edge

RulesHouse edge per hand, best switching and chart
6 decks, dealer hits soft 170.54%
6 decks, dealer stands on soft 170.15%
8 decks, dealer hits soft 170.59%
Classic blackjack for comparison (6 decks, dealer hits soft 17, 3:2)0.62%
The switch is not free. It is paid for by the 1:1 blackjack and the dealer 22 push. If you never switch, the house edge with these rules jumps to 9.84% per hand.

When to switch

Compare the two pairings: the hands as dealt and the hands after the swap. Look up each hand in the table below against the dealer's card and add the two numbers. Switch when the swapped pair adds up to more.

Each number is the average result of one hand, in % of its bet, with the dealer showing that card and no dealer blackjack. Following this table loses only 0.0004 percentage points against the exact best switch for every deal. The game above checks your choice against that exact answer and explains it with these numbers.

Switch or not?

Enter both hands as dealt and the dealer's up card.

How to play the hands after the switch

Because a dealer 22 pushes, the chart doubles less and hits more stiff hands than the classic chart. Hard 17 and more, and soft 19 and more: stand. Totals not in the chart: hit. The full chart for this table is under the game; the cell for your decision is outlined while you play.

How the numbers are worked out

For every up card and every possible deal of four cards, both pairings are valued exactly from the cards left in the shoe, played by the chart; the better pairing is the switch. An independent simulator of our own, written without access to the calculation, reproduces the house edge within its margin of error over 4 billion rounds. Split hands are treated as independent.

A dealer 22 is also a push in Free Bet Blackjack, where it pays for free doubles and splits instead.
