Before you jump in, you'll need to learn key strategical points and differences between playing single deck Blackjack and standard multi-deck.

Single vs Multiple Deck Blackjack

Back in the good old days, single deck Blackjack was the standard.

It was played widely around the world, with blissful players taking advantage of the 0.15% house edge.

It became popular with card counters, who swooped in with their own single deck Blackjack strategy to take a piece of the pie. The use of one deck makes card counting easy, but Casinos caught on quickly.

They began introducing Blackjack games with a double deck or more decks to raise their own edge and make it harder to count cards.

So, what are the differences between these types of Blackjack? Besides the number of decks, the payout is generally different as well—you'll find that many Casinos offer payouts of 6:5 in single-deck games, while multi-deck games generally pay 3:2.

Rules & Gameplay for Single Deck Play

The basic concept and objective remain the same in single deck Blackjack. You want to get to 21 points or as close to 21 as possible without busting.

Not the best hand in the history of single deck Blackjack...

You'll place your bet, then the dealer will deal the hands. You'll get two face-up cards, and the dealer will get one face-up and one face-down.

You'll study your cards and the dealer's upcard, then decide to hit, stand, split, or double down.

Remember, both land-based and online casinos usually have specific rules for single-deck Blackjack which differ from multi-deck. These include:

  • Whether or not the dealer hits or stands on soft 17
  • Whether or not players may double down after a split
  • If and when players can surrender

It's common to have the dealer hit on a soft 17, to prohibit players from doubling down after a split, and to prohibit surrender because these rules increase the house edge.

However, these and other rules will vary depending on the online Casino site of your choice

Hard Hands

  • 5-7: Always hit
  • 8: Double if dealer shows 5 or 6, otherwise hit

  • A-4: Double if dealer shows 4-6, otherwise hit
  • A-5: Double if dealer shows 4-6, otherwise hit

  • 7-7: Split if dealer shows 2-7, stand on 10, hit on 8, 9 & ace
  • 8-8: Always split
  • 9-9: Split if dealer shows 2-6 and 8-9, otherwise stand
  • 10-10: Always stand
  • Ace-Ace: Always split

Keep in mind that this is not an optimal strategy for every game, because you won't just make different plays according to the dealer's upcard; single deck basic strategy play Blackjack is also dependent on the house rules.

House Rule Variations

If the dealer stands on soft 17, you know that he has no chance of improving this hand. Keep this in mind as you make your decisions, because it actually increases your odds of beating him with certain plays.

Double down rules will affect your bets, so pay close attention to them.

If you can double down after a split, you'll want to be a bit more aggressive with your splits than the guide displays—for example, you could split a pair of 3s if the dealer shows 2 or 3, not just 4 through 6.

Likewise, if you can surrender, you'll want to do so strategically. For example, if you have a pair of sevens and the dealer shows 10, you know your odds aren't good, so surrendering would be the best option.
