What is Spanish 21?

Spanish 21 is a special take on the classic game of blackjack. Brick and mortar casinos first introduced the game in 1995. While many of the rules are inherently the same as the original version, this one has a few different twists that can make the gameplay much more interesting. Additionally, such rules can be found in other blackjack games like Pontoon and Blackjack Surrender, both of which offer some big advantages to the player.  

Usually, Spanish 21 features the same table layout as the classic version of blackjack. This means between 6 and 8 decks of cards are used. Unlike other blackjack games, however, this one does not include 10 cards. Basically, this means 25% of the cards are missing. Jacks, Queens, and Kings remain in the deck, and like the original game, these cards have a value of 10. 

Spanish 21 Quick Facts

  • This version of the game is played with 6-8 card decks with 48 in each
  • All suited 10 cards are excluded from the game 
  • If the player has 21, their hand always supersedes the dealer’s 21;
  • The house edge falls in the range of 0.40%-0.76% in Spanish 21 and can be reduced by 1%, respectively.

Spanish 21 Rules

As mentioned already, Spanish 21 discards all of the 10 cards from the deck. At first, it may seem like this puts the player at a huge disadvantage. But the other changes in rules make up for this. Here are some quick pointers to help you remember the rules and what to be aware of while you play. 

Quick rules for Spanish 21:

  • Player’s 21 always beats the dealer’s 21
  • The dealer must either hit or stand on soft 17
  • Redoubling is possible up to 3 times at most casinos
  • You may opt to surrender on the first two cards
  • All 10s are removed from every deck being played (6-8 decks is standard)
  • The dealer must hit on 16 and stand on 17
  • Even against a dealer’s blackjack, player’s 21 always wins
  • You may double down after a split
  • After splitting Aces, players can draw several cards from the shoe
  • Receive bonus payouts for hands like 6-7-8, and for a 5-card trick that totals 21, e.g. 2-3-4-5-7

Rules for Hitting, Standing, and Splitting

In this version of the game, all rules for splitting, hitting, and standing are exactly the same as in the original game ofonline blackjack. This means that you are only allowed to stand, hit, or split once you’ve placed your wager, and only when the dealer has dealt your initial hand. A Spanish 21 strategy chart is a great way to assess the impact these rules can have on the game before making your move ─ but more on that later!.

Using the Late Surrender Rule

To go for a late surrender in blackjack means you are essentially forfeiting your hand to keep half of your stake. For the player, this can be extremely advantageous, and if you calculate the probability of beating the dealer’s hole card, you can minimize losses significantly with this move.

Using the Re-Splitting Rule

Being able to split and re-split Aces is another advantage of playing Spanish 21. You can also double down, and re-double on a pair in this version of the game. When doubling and splitting, you can also use the late surrender rule if you don’t want to risk losing half of your bet. If you know you’ve got a lousy hand to begin with, knowing you’ve got all of these rescue options at your disposal is a huge benefit.

Rules For Matching the Dealer’s Side Bet

In addition to the variations of rules above, there are normally some extra bonus games and side bets you can place in Spanish 21. One of the most popular side bet in this version of the game as well as classic blackjack and other variations are “Match the Dealer.” In order to win this bet, the player’s first two cards must match the dealer’s face card. While it can be a lot of fun, this bet can be risky, and should therefore be avoided if you want to keep losses to a minimum. 

Online Spanish 21: The Super Bonus Rule

Unlike other variations of blackjack, Spanish 21 is one of the few online variants that offer a Super Bonus. Actually, the odds of actually hitting a Super Bonus payout is about 1 in 668,382 in a game with six decks and 1 in 549,188 in an 8-deck game. But the thought of winning such a payout is enthralling in itself.

Spanish 21 Playing Tips

As Spanish 21 doesn’t use 10s, there is a much lower risk of busting your hand in this game. This is why drawing extra cards is going to be worth your while in most cases. You can also use surrender but bear in mind that overusing this option may lose you more money in the long run. Below are our top tips for playing Spanish 21 and how you can make the most out of your bets. 

Get to know the different moves with a strategy chart

As the rules in Spanish 21 are different from classic blackjack, it’s worth taking some time to research the moves and possible outcomes that can occur. A strategy chart is the best way to get you familiar with the rules of the game. It can drastically improve your winning chances. 

Don’t draw extra cards if bonus payouts are offered

It may seem a bit counterintuitive to do this when there is a bonus payout up for grabs. But if you’re quite new to the game and haven’t had much experience with these features ─ as well as side bets ─ we highly recommend avoiding them. While it may be tempting to put down a big wager, it’s these kinds of bets that can ruin your bankroll in minutes.  

Be cautious of using the surrender too much

New players often overuse surrender in blackjack. While this is fine if you’ve got a big bankroll to play with, the losses can rack up quickly if you’re abusing this option. There are ideal times to call surrender. But this doesn’t mean you’re going to finish in the green if you plan to stick around for a few games. Therefore, it’s much wiser to use this option sparingly and play your hand as best you can.   

Extra cards don’t always bust your hand

10-value cards are under-represented in this version of blackjack. Therefore, there is a much lower risk of your hand going bust. This is why it’s typically more profitable to draw more cards in this game.

Ignore the Dealer side bet

Match the Dealer is a common side bet in Spanish 21. This bet can result in a large payout. The odds range between 4:1 to 18:1 depending on which card’s match the dealer’s face-up card. The not-so-great news about this bet is that the house edge sits between 3.99% and 3.06% in an 80-deck game. Naturally, this can pose a high risk to your bankroll. Therefore, skip these bets if you can and stick to the safer bets in the game.
