Spanish 21 Blackjack Game – Rules, Review & Strategy. This is a blackjack variation that got its name because it is played with six or eight Spanish decks – a regular 52 card deck from which the four tens cards are taken out.

Introduction

Spanish 21 is a variation of blackjack, that in some cases is the best bet in the casino. In locations where the dealer stands on a soft 17, or redoubling is allowed, Spanish 21 may be a better bet than blackjack, depending on the specific blackjack rules. If you are looking for a change of pace from traditional blackjack but insist on a game with a low house edge, then you may find new excitement in Spanish 21.

In Australia and Malaysia, Spanish 21 is called Pontoon. There are some rule changes in Australia, which merit a separate page. For all the details please visit my page on Australian Pontoon. To make matters more confusing, there is another similar game, but different enough to warrant a separate page, called Player's Edge 21.

Following is a list of known aliases of the game:

  • Betsoft, a major provider of software for Internet casinos, offers Spanish 21 under the name Pirate 21.
  • The Casino Bregenz in Austria changes the name to Blackjack Exchange.

The Rules

Spanish 21 uses six or eight Spanish decks, each deck consisting of 48 cards — the regular 52 cards less the four tens. Any card counter can tell you that removing any 10-point card from the cards moves the odds in favor of the dealer. To make up for this, Spanish 21 gives the player a host of bonuses and favorable rules. There are lots of Spanish 21 games all over the country, so rules will vary somewhat from place to place, but the usual rules in the player's favor are:

  1. Late surrender allowed.
  2. Double after split allowed.
  3. Re-splitting aces allowed.
  4. A player 21 always wins.
  5. Player blackjack beats dealer blackjack.
  6. Player may double on any number of cards.
  7. Player may usually hit and double down after splitting aces.
  8. Player may surrender after doubling, known as 'double down rescue.' The player forfeits an amount equal to his original bet.
  9. A five-card 21 pays 3 to 2, a six-card 21 pays 2 to 1, a seven or more card 21 pays 3 to 1. Bonus not honored after doubling.
  10. A 6-7-8 or 7-7-7 of mixed suits pays 3 to 2, of the same suit pays 2 to 1, and of spades pays 3 to 1. These bonuses do not pay after doubling.
  11. Suited 7-7-7 when the dealer has a seven face up pays $1000 for bets of $5-$24 and $5000 'Super Bonus' for bets of $25 or over. In addition, all other players receive a $50 'envy bonus.' This bonus does not pay after doubling or splitting.

Variable Rules

  1. Dealer may hit or stand on a soft 17.
  2. 6 or 8 Spanish decks can be used.
  3. Some casinos allow redoubling, up to three times.
  4. I have heard of some casinos not allowing surrender or drawing to split aces, but it isn't the norm.
  5. A face card and ace after splitting has been known to count as a blackjack, at at least one casino.
  6. There has been a lot of debate through the years whether the bonuses are payable after a split. First, there is almost no argument that they do not pay after doubling. However, the way the game was designed, all bonuses except the Super Bonus are supposed to be payable after splitting. However, most casinos do not pay the bonuses after a split. The effect of not allowing the bonuses after splitting is very small, around 0.01%.

Strategy

Following is my Spanish 21 basic strategy when the dealer hits a soft 17.

Next is the Spanish 21 basic strategy when the dealer stands on a soft 17.

Note: If drawing to split aces is not allowed, and the dealer stands on soft 17 (as is the case at the Mohegan Sun), then hit A,A vs A.

The next table if for when the dealer hits a soft 17, redoubling is allowed, and the player has not already doubled.

The next table if for when the dealer hits a soft 17, redoubling is allowed, and the player has already doubled, which limits his options to stand, surrender, and double again.

Many readers have expressed doubt about my advice to hit 17 against an ace with 3 or more cards. However, I stand by what I said. The player will save about 2.8% of the initial wager by hitting as opposed to standing. The dealers will advise against this play and the other players may curse the day you were born, but trust me, the odds favor hitting.

Following is the house edge under various common rules, before considering the Super Bonus.
  • Dealer stands on soft 17: 0.40%
  • Dealer hits on soft 17, redoubling allowed: 0.42%
  • Dealer hits on soft 17, redoubling not allowed: 0.76%

Super Bonus

The probability of hitting the Super Bonus is 1 in 668,382, with six decks, and 1 in 549,188 with eight decks. The reduction in the house edge depends on the bet amount, and to a lesser extent, the number of players. With no other players, and bets of exactly $5 or $25, the Super Bonus lowers the house edge by 0.030% in a six-deck game, and 0.036% in an eight-deck game. At a bet of exactly $5, the Envy Bonus lowers the house edge by an additional 0.0015% in a six-deck game, and 0.0018% in an eight-deck game, per additional player.

For bet amounts other than those indicated above, the benefit of the Super Bonus will go down as the bet amount goes up.

No Draw to Split Aces: At the Mohegan Sun drawing to split aces is NOT allowed. The effect of this rule is to increase the house edge by 0.29%.

Ace and 10 after splitting aces pays 3 to 2: I have an unconfirmed report that at at one time the Meskaki casino in central Iowa paid 3 to 2 on an ace and 10 after splitting aces. I have another unconfirmed report that as of Aug. 2010 they removed the Spanish 21 table completely. According to my calculations this lowers the house edge by 0.16%. Otherwise they hit a soft 17 and no redoubling, for an overall house edge of 0.60%.

Doubling only allowed on first two cards: I had a false report that a casino in Malaysia didn't allow doubling on any number of cards. If such a rule did exist, it would increase the house edge by 0.16%.

Match the Dealer

Match the Dealer is a side bet found in both blackjack and Spanish 21. The player wins for each of his initial two cards that match the dealer's up card. Matches in rank only pay less than a match in rank and suit. The following tables show the various pay tables that I am aware of for Spanish 21.

Methodology


Spanish 21 strategy The Spanish 21 strategy found here is based on a combinatorial program which considered both card composition and the six deck nature of the game. In addition an infinite deck model was created in Excel, of which the basic strategy nearly agreed with that of the combinatorial model. The basic strategy found here does not agree with that of the late Lenny Frome in some borderline situations. Frome's strategy can be found in such books as 'Secrets of the New Casino Games' (Marten Jensen) and 'Armada Strategies for Spanish 21' (Frank Scoblete). Although I have a great deal of respect for Frome and his body of work, I strongly feel that his basic strategy is incorrect. I speculate he did notincorporate the double down surrender feature correctly into his analysis. My strategies also agree with those of Katarina Walker, who has done an amazing job analyzing Spanish 21 and its cousin, Australian Pontoon, as well as an independent analysis by Mike Hopson.

Imagine playing the game of Blackjack with a 48-card deck that contains no natural 10’s. That is exactly the concept behind Spanish 21, a fast-paced casino table game that uses six or eight “Spanish” decks without 10-spots. It is still possible to get a two card 21 with an Ace and a face card, but the elimination of 10’s adds a new dimension to doubling down and other aspects of the game.

On the face of it, removing the 10’s should improve the house edge significantly, and it does—by about 25 percent. But the way Spanish 21 rules are set up, the odds in favor of the dealer winning a hand can actually be less than they are in classic Blackjack.

For one thing, doubling is allowed at any time on any card total. Also, redoubling is allowed after a double. The player’s blackjack beats the dealer’s blackjack, which would normally be a push or even money at best. And the player’s 21 beats the dealer’s 21, which would always be a push, otherwise.

Other differences separating Spanish 21 from classic Blackjack include:

– Aces can be re-split.

Spanish 21

– Hitting and doubling down are allowed after splitting Aces.

– Late surrender is allowed (except facing a dealer’s natural blackjack).

– “Double Rescue” allows surrender after doubling down.

– Five-card 21 pays 3-to-2.

– Six-card 21 pays 2-to-1.

– Seven-card (or more) pays 3-to-1.

Spanish 21 Strategy

– Mixed suit 6-7-8 or 7-7-7 pays 3-to-2.

– Same suit 6-7-8 or 7-7-7 pays 2-to-1.

To keep the game interesting and players on their toes, a number of variable rules can be applied depending on the casino. These include allowing bonuses to be paid on split or doubled down hands; a Super Bonus paid on suited 7-7-7 when the dealer is showing a 7; and special rewards for bonus hands in spades. Some casinos have the dealer stand on soft 17, while others require a hit. And some house rules limit the number of redoubles to three or fewer.

Obviously, the strategy for play is affected by the missing 10’s and the special rules. For example, players can be more aggressive about hitting, with somewhat less concern about busting and more incentive to reach a multi-card 21 total. One basic tenet is to always stand on 18 or more and hit any total of 8 or less. Strategies for hitting, splitting, standing, and surrendering on totals of 9~17 can be quite complex.

Ironically, although there are more opportunities to double down in Spanish 21, the times it is wise to do so are actually less frequent. That’s because of the 25 percent reduction in the number of cards valued at 10. As a general rule, avoid doubling on soft hands except soft 16 against a dealer’s 6 and soft 17 or 18 facing a 4, 5 or 6. As for hard totals, doubling is a good idea on 9 facing a 6; 10 facing a 2~7; and 11 facing 2~8.

Under the basic rules for Spanish 21, the house edge is just 0.40~0.42 percent, which is considerable better than Roulette or Craps. If redoubling is not allowed and the dealer hits on soft 17, the house advantage increases to 0.76 percent, so look for versions that permit redoubles and force the dealer to stand on all 17’s.

Also, look for other rule variations that can affect the odds. A six-deck game is usually preferable to one using eight decks. The existence of an envy bonus paid to active players when a Super Bonus is hit will lower the house edge slightly. And if a face card with an Ace is allowed to count as a blackjack after splitting, that obviously favors the player.
