Spanish 21 is another popular blackjack spin-off. In fact, many experienced players tend to prefer hitting these tables due to the built-in bonuses that can be won without placing a side bet. If you’re not familiar with the ins and outs of this game, we have all the info you’ll need to get started. 

Alternatively, for those that are chomping at the bit to play, simply look through the list of top Spanish 21 casinos below and pick your favourite. Registration is quick and easy, so you’ll be playing this awesome game within minutes.

Spanish 21 Review


It’s quite a testament to the original 21 game, Vingt-et-Un, that so many popular variants have arisen from it. Spanish 21 can be included in that list. It shares many characteristics with blackjack, yet it is distinct enough to stand on its own. It is also quite similar to a variation of pontoon played in Australia and Singapore, but still independent enough to be recognised by itself.

So, what’s the appeal? With a plethora of blackjack games filling the virtual shelves at our top online casinos, why do many players make a beeline for this particular one? Our Spanish 21 review has discovered the answer.

What is Spanish 21


Having established that Spanish 21 is a type of blackjack, we all know that the objective is to hit 21. Even if you didn’t before, the ‘21’ is the game’s title drops a rather large hint. Now, of course, there needs to be enough tweaks, adjustments and changes from original blackjack for this game to stand alone, and there certainly are. For starters, it is played with eight 48-card decks. All of the tens have been removed but the value of the remaining cards stays the same: ace = 1 or 11, number cards = their face value and all picture (face) cards = 10.

The major difference is the bonus payouts players can enjoy playing Spanish 21. No other blackjack variant offers a 50:1 in-game bonus. There are many games with side bets, and let’s not forget Progressive Blackjack, but these are all additional wagers. With this game, you don’t have to bet extra to take part, you simply need to play. That’s what is Spanish 21’s secret to its success.

Spanish 21 Rules


The house edge, also known as the casino advantage, is 0.49% for Spanish 21. That means the theoretical return to player (RTP) value is 99.51%. So, over the history of the game, it pays out £99.51 for every £100 wagered. In reality, the payout is at least a few percent lower because most players don’t follow the optimum strategy or they make the odd error. 

Looking at the Spanish 21 rules, you’ll notice a mixture, with some being pro-player and others pro-casino. For clarity, we’ve taken our guidance from Microgaming’s online version of Spanish 21. Land-based games may have a few slight modifications.

  • Blackjack pays 3:2
  • Insurance pays 2:1
  • Normal winning hand pays 1:1
  • Dealer peeks for blackjack if showing an ace or 10-valued card
  • Dealer hits on soft 17
  • Player’s blackjack beats dealer’s blackjack
  • Player’s 21 beats dealer’s 21
  • Late surrender available (includes after doubling)
  • Double down on any number card
  • Re-double down once
  • Double down after splitting allowed
  • Can split cards of equal value
  • Can split three times (max. four hands)
  • Aces cannot be re-split
  • Draw and double down to split aces

With splitting to make four hands, plenty of doubling down options and late surrender, there’s plenty of positive action on the player’s side. It’s a shame aces cannot be re-split but this is how the rules of all blackjack games work. They giveth and they taketh away is the phrase we like to use. 

Spanish 21 Bonus


In addition to the standard payouts described above, you have the Spanish 21 bonus payouts. These do not apply after doubling down or if you have blackjack.

It’s also worth looking out for any bonuses and promotions the casinos may have that can help boost your Spanish 21 bankroll. In our experience, most operators are fairly tight when it comes to RNG blackjack offers. This is due to the extremely low house edge compared to many other games.

Still, if you look around, you’ll come across something that can be used to assist your advantage. It might be a small matched deposit offer, a cash back special or perhaps the casino VIP scheme rewards players of this game. It’s certainly worth doing some research as it could swing the scales in your favour.
