Good question. Yes, this house edge is definitely low enough to consider card counting. Since most card counters don't even consider Spanish 21 I think the field is ripe to exploit the game and to do so with a great deal of impunity. However counting may not be as effective in Spanish 21 as regular blackjack. A small card rich deck will benefit the player in more multiple card 21's. To the best of my knowledge nobody has developed index numbers for Spanish 21 but somebody should. Maybe I will.
Casino Player reversed the two charts in their layout. I'm very embarrassed by this mistake. Yes, you should hit a hard 17 against an ace if you can't surrender.
The house edge for Spanish 21 is generally better than the house edge in blackjack. If you ignore the effect of those jackpot hands, which come up as rarely as you might expect, the house edge for Spanish 21 is about 0.4%. This assumes, of course, that you're playing with perfect basic strategy.
- Spanish 21 features a number of rules that make it more exciting than your average blackjack game. My personal favorites include the Super Bonus, Charlie rule, late surrender, and doubling down on any total. But the drawbacks are that all 10s are removed from the deck, and the game always uses either 6 or 8 decks.
- I recently started playing Spanish 21 because the rules at the local Thunder Bay casino give it much better odds than Blackjack. The dealer stands on soft 17, but uses 8 decks of cards. Does using 8 decks give better or worse odds for the player than the 0.40% you calculated with 6 decks?
- Suggesting all games are played with six decks - which is a common size for a blackjack shoe - Spanish 21 has the best house edge for the player according to the blackjack house edge table on top of this page. Standard 21 Blackjack is good too since you can actually have the edge by playing perfect basic strategy with a single deck.
In a 6-deck game the probability of a super bonus is 1 in 668382, and in an 8-deck game it is 1 in 549188. The house edge without the super bonus would be 0.03% more either way.
Spanish 21! Under Atlantic City rules blackjack has a house edge of 0.43% and Spanish 21 of .40%.
The Venetian. To the best of my knowledge they are the only casino in Las Vegas which stands on a soft 17 in Spanish 21, lowering the house edge from 0.76% to 0.40%.
Update: The Venetian later switched to hitting a soft 17. As of this update (May 14, 2013) the best Spanish 21 game is at the D, which allows re-doubling.
All Unified Gaming casinos as well as Global Player offer Spanish 21. Unified Gaming stands on a soft 17 and thus has the lower house edge.
2013 Update: Unified Gaming software has since disappeared. As far as I know, nobody offers Spanish 21 online any longer.
Thanks for the compliment. The Spanish 21 rules are the same across Atlantic City. I only know of two that have the game, the Tropicana and the Claridge, but there could be others by now. If I'm not mistaken, the best craps game is at the Sands, which offers 5X odds. When I say to take the maximum odds I mean bet the maximum allowed on the odds. For example, $50 after a $10 line bet. Keep in mind that you won't win more money by taking the odds, you just get to bet more without losing more in the long run.
I always liked the name Thunder Bay for a city. I used to work at a summer camp not too far from there in Missanabie, Ontario. To answer your question 6 decks is better than 8. However the difference in the house edge is small, only about 0.03%.
With reference to the first table of the Basic Strategy for Spanish 21, I have some questions that I hope you could clarify for me (standard game, dealer hits s17):Q1. For 17 v A (your reference - Rh). If the player doesn't surrender (or double down surrender), does he in fact hit? I ask this question because I'm a little unsure - Scoblete's book says to stand 17 v A, as does Norm Wattenberger's Spanish 21 strategy table in CVBJ3.
Spanish 21 Vs Blackjack
Q2. Your references to the 6-7-8 bonuses. Do all the references apply equally to the 7-7-7 bonuses? e.g. Does * mean 'Hit if any 6-7-8 [OR 7-7-7] bonus possible'?
Q3. p20 of Scoblete's Spanish 21 book says to hit 9 v 6 if player has a 3 card 9. Should I ignore this advice, along with the 'don't double down rescue' advice given in his book?
Sorry to bother you with these questions but I've got a Spanish 21 tournament coming up, and need all the help I can get. Many thanks.
- Yes, you should hit. I believe all those who disagree to be in error.
- No, the 7-7-7 bonus is only possible with two initial sevens. The proper strategy is indicated in that row.
- Yes, you should ignore this advice.
I get verbally abused too when I play Spanish 21. When I lived in Baltimore I played it a lot in Atlantic City because the house edge is lower than blackjack there. These idiots doing the abusing don't understand that removing the tens from the decks makes hitting less dangerous because the probability of busting is less. Don't bother to try to explain this, the logic won't make it through their thick skulls. I used to just bite my tongue in these situations but the next time I may not be so nice.
There was discussion about this at www.bj21.com under the Green Chip section about a couple years ago. Free online slot games to play now. As I recall the consensus was that counting was not as advantageous as in blackjack but you could get away with a lot more. I know of no published material on this.
Most redoubling situations tell you to double anyway. However, with a soft 15 to 17 against a 3, when the strategy says hit, you should actually redouble.
Thanks. This game is just a rip-off of Spanish 21. Note that the bottom of the card says that all queens are removed.
Keeping all the tens in the deck is worth 1.89% to the player. The house edge under those rules is normally 0.40%. So with all the tens in the shoe, the player edge would be 1.89%-0.40% = 1.49%.
Spanish 21 Side Bet Odds
I don't like it when games give worse odds to the higher bettors either. The value of these Super Bonuses is almost zero. The probability of hitting the Super Bonus is one in 549,000 with eight decks, and one in 668,000 million with six decks. Assuming six decks, the value of the envy bonus is worth 0.0015% per additional player, besides yourself. Sorry, I don't know of any casinos that sweeten the bonuses for larger bets.
I really enjoy your site, and thank you for the pertinent information! Reading and learning has erased my bad habits and made me a better player, I am certain! Here is my question. I read about games you write about and really think that some of them would be fun to try, like the World Series of Poker (Final Table Bonus) video poker game.Not knowing, however, where to find it, and others, I usually wind up writing to the maker of the game at their website and asking where I can find their game outside of Nevada, since I am in the Midwest. I NEVER get an answer! Besides being just bad customer service, I still have the question of finding the game to be answered. Do you know of a site, or a way, to find which specific games are at which casinos? You would think the game's manufacturer would list where to find it to assist in letting players find the game.
Thanks for the kind words. I think the gaming manufacturers should take this as a good suggestion. I get requested for this information by players all the time, but it is simply too much for one person to keep on top of. A noteworthy exception is Masque Publishing, the owners of Spanish 21. They keep an online list of where the liberal Spanish 21 rules can be found.
The strategy for such blackjack variation as Spanish 21 was developed by many different blackjack experts, including Arnold Snyder and John Grochowski: actually, these two blackjack authors were the most successful ones who perfectly described Spanish 21 Strategy in a way understandable for average players.
Spanish 21 Blackjack Vs Regular Blackjack
These two authors - Arnold Snyder and John Grochowski are considered to be the masters of the game, so follow their recommendation to succeed at the game. The strategy for Spanish 21 has the same principles with other blackjack strategies: it means that all options to do were organized and introduced with the help of special strategy charts which described the steps to follow. Due to the fact Spanish 21 is played with a deck of cards where 10's are absent, the strategy to win this game has some extra features of course; frankly speaking, this strategy is rather complicated and difficult to understand if you are just a newcomer to this game.
Anyway, here you will find 2 strategies for Spanish 21; they were facilitated by gambling specialists for you to understand and remember them properly.
Arnold Snyder's Strategy
The basic Spanish 21 strategy was described by Mr. Snyder in his book (The Big Book of Blackjack); he had made an attempt to explain its main aspects for average players to understand it and introduced 15 basic steps to do during the game.
- Do not take insurance.
- Double down if you have a hand of 11.
- Double down if you have a hand of Ace + 5,6,7.
- Double down if you have a hand of 20 and a dealer has 2-8.
- Hit if you have a hard hand of 12-13.
- Hit if you have a soft hand except of the following soft hands: Ace + 5,6,7.
- Hit if you have a hard hand of 14-15 and it consists of 5 or more cards.
- Hit if you have a soft hand of 17-18 and it consists of 5 or more cards.
- Stand if you have a hard of soft hand of 18.
- Stand if you have a hand of 14-16 and a dealer has 2-6. Hit this hand if a dealer has 7-Ace.

- Never split 4's, 5's and 10's.
John Grochowski's Strategy
Mr. Grochowski is the gambling specialist who described the strategies of various casino games in his books; as for Spanish 21, his strategy introduces 3 main rules for gamblers to follow: a rule for hard hands, a rule for soft hands and a rule for splitting pairs. As far as we know, all blackjack strategies created in this way. So:
- Hard hands: stand if you have 18 or more; hit if you have 8 or less.
- Soft hands: always stand on 19-21.
- Splitting pairs: split Aces; never split 4's, 5's and 10's.
