Blackjack is the American version of a popular global banking game known as Twenty-One, whose relatives include Pontoon and Vingt-et-Un. It is a comparing card game between one or more players and a dealer, where each player in turn competes against the dealer.
- Dealer peeks on Aces and 10-point cards
- Double down on any 2 cards
- Split once to make 2 hands
- One card to split Aces
- A split Ace and a 10 counts as 21
- Unlike 10-point cards can be split
- Minimum Bet: 1
- Maximum Bet: 1000
- Other rules are adjustable
This is our first blackjack game and trainer and I'm proud to finally add our version 2 with enhanced graphics and the ability to learn how to count cards to my website. The game is mostly self-explanatory. If you make an inferior play, the game will warn you first. I recommend that before you play for real money both online in person that you practice on the game until you very rarely are warned you a making an inferior play. If doubling or splitting is mathematically the correct play, but you don't have enough chips, the game will give the best advice for what you can afford to do. Do not change rules mid-hand. If you do, the change will not take effect until the next hand. The advice is based on my own analysis and basic strategy tables for one, two, and four+ decks. The deck(s) is(are) shuffled after every hand.
Blackjack Rules When To Split 2
If you find any bugs, please contact me. A screenshot would be appreciated if you claim the game is misplaying a hand. I get a lot of incorrect reports that the advice given is incorrect. This usually can be explained by the user not using the correct basic strategy for the rules selected. I have also had many comments about the advice on a player 16, composed of 3 or more cards, against a 10. As a rule of thumb, the player should stand in that situation. However, that is a basic strategy exception. The game only knows basic strategy. Also, please note that it is a standard blackjack rule that split aces get one card each. If one of them is a ten, it is not a blackjack, it is just 21 points. That is how blackjack is usually played.
I would like to thank JB for his outstanding work on this game, and Dingo Systems for the cards.

Rules
I overhear a lot of bad gambling advice in the casinos. Perhaps the most frequent is this one, 'The object of blackjack is to get as close to 21 as possible, without going over.' No! The object of blackjack is to beat the dealer. To beat the dealer the player must first not bust (go over 21) and second either outscore the dealer or have the dealer bust. Here are the full rules of the game.
- Blackjack may be played with one to eight decks of 52-card decks.
- Aces may be counted as 1 or 11 points, 2 to 9 according to pip value, and tens and face cards count as ten points.
- The value of a hand is the sum of the point values of the individual cards. Except, a 'blackjack' is the highest hand, consisting of an ace and any 10-point card, and it outranks all other 21-point hands.
- After the players have bet, the dealer will give two cards to each player and two cards to himself. One of the dealer cards is dealt face up. The facedown card is called the 'hole card.'
- If the dealer has an ace showing, he will offer a side bet called 'insurance.' This side wager pays 2 to 1 if the dealer's hole card is any 10-point card. Insurance wagers are optional and may not exceed half the original wager.
- If the dealer has a ten or an ace showing (after offering insurance with an ace showing), then he will peek at his facedown card to see if he has a blackjack. If he does, then he will turn it over immediately.
- If the dealer does have a blackjack, then all wagers (except insurance) will lose, unless the player also has a blackjack, which will result in a push. The dealer will resolve insurance wagers at this time.
- Play begins with the player to the dealer's left. The following are the choices available to the player:
- Stand: Player stands pat with his cards.
- Hit: Player draws another card (and more if he wishes). If this card causes the player's total points to exceed 21 (known as 'breaking' or 'busting') then he loses.
- Double: Player doubles his bet and gets one, and only one, more card.
- Split: If the player has a pair, or any two 10-point cards, then he may double his bet and separate his cards into two individual hands. The dealer will automatically give each card a second card. Then, the player may hit, stand, or double normally. However, when splitting aces, each ace gets only one card. Sometimes doubling after splitting is not allowed. If the player gets a ten and ace after splitting, then it counts as 21 points, not a blackjack. Usually the player may keep re-splitting up to a total of four hands. Sometimes re-splitting aces is not allowed.
- Surrender: The player forfeits half his wager, keeping the other half, and does not play out his hand. This option is only available on the initial two cards, and depending on casino rules, sometimes it is not allowed at all.
- After each player has had his turn, the dealer will turn over his hole card. If the dealer has 16 or less, then he will draw another card. A special situation is when the dealer has an ace and any number of cards totaling six points (known as a 'soft 17'). At some tables, the dealer will also hit a soft 17.
- If the dealer goes over 21 points, then any player who didn't already bust will win.
- If the dealer does not bust, then the higher point total between the player and dealer will win.
- Winning wagers pay even money, except a winning player blackjack usually pays 3 to 2. Some casinos have been short-paying blackjacks, which is a rule strongly in the casino's favor.
Wizard's Simple Strategy
I've been preaching for years that to play blackjack properly requires memorizing the basic strategy. However, after pitching the basic strategy for 20 years, I've learned that few people have the will to memorize it. In my book, Gambling 102, I presented a 'Simple Strategy,' which is seven simple rules to playing blackjack. The cost due to incorrect plays with the Simple Strategy is 0.53%, under liberal Vegas Strip rules.
Ever since my book was published it has bothered me that the cost in errors to my Simple Strategy was too high. So in September 2009 I developed the following 'Wizard's Strategy.' The cost due to imperfect plays is 0.14% only, relative to liberal Vegas Strip rules. That is the cost of one hand for about every 12 hours of play. Compared to the 250 cells in the Basic Strategy, the Wizard's Strategy has only 21, as follows.
Let me be perfectly clear that this strategy is not right 100% of the time. I continue to get Emails saying that when this strategy was used with my practice game, the player was corrected for following it. For example, my simple strategy says to stand on 12 against a 2, when it is mathematically better to hit. If you want to learn a strategy that is correct all the time you should use the appropriate basic strategy for the set of rules you are playing.
Here are some comments of clarification.
- A 'hard' hand is one that either has no aces, or has aces that are forced to count as point, lest the hand bust. A 'soft' hand is one with at least one ace, which may still count as one or eleven points.
- With a hard 10 or 11, double if you have more points than the dealer, treating a dealer ace as 11 points. Specifically, double with 10 against a 2 to 9, and with 11 against 2 to 10.
- If the strategy says to double, but you have three or more cards, or table rules don't allow soft doubling, then hit, except stand with a soft 18.
- If the strategy says to surrender (16 vs. 10), but you can't for whatever reason, then hit.
- If the strategy says to 'not split,' then treat the hand has a hard total of 8, 10, or 20, according to the pair in question.
A reader named Jeff provided another table of my simple strategy, with exceptions in small print. Details about the Wizard's Simple Strategy can be found in my Blackjack appendix 21.

Beware Short Pays on a Blackjack
More and more tables are showing up that pay less than the full 3 to 2 on a blackjack. Most of these tables pay 6 to 5, but some even money and 7 to 5 tables are known to exist. I would estimate that 10% of '21' tables in Las Vegas now pay less than 3 to 2. In my opinion, only games that pay 3 to 2 deserve to be called 'blackjack,' the rest fall under '21' games, including Super Fun 21 and Spanish 21. Regardless of the other rules, you should demand nothing less than 3 to 2 blackjack. You should always check the felt to be sure, and if the felt doesn't say, look for a sign. If nothing says the win on a blackjack, then ask.

Bad Strategies
Three popular bad strategies encountered at the blackjack table are: never bust, mimic the dealer, and always assume the dealer has a ten in the hole. All three are very bad strategies. Following are my specific comments on each of them, including the house edge under Atlantic City rules (dealer stands on soft 17, split up to 4 hands, double after split, double any two cards) of 0.43%.
Never bust: For my analysis of this strategy I assumed the player would never hit a hard 12 or more. All other decisions were according to correct basic strategy. This 'never bust' strategy results in a house edge of 3.91%.
Mimic the dealer: For my analysis of this strategy I assumed the player would always hit 16 or less and stand on17 or more, including a soft 17. The player never doubled or split, since the dealer is not allowed to do so. This 'mimic the dealer' strategy results in a house edge of 5.48%.
Assume a ten in the hole: For this strategy I first figured out the optimal basic strategy under this assumption. If the dealer had an ace up, then I reverted to proper basic strategy, because the dealer would have peeked for blackjack, making a 10 impossible. This 'assume a ten' strategy results in a house edge of 10.03%.
