This Blackjack Basic Strategy app allows you to quickly lookup the best basic strategy for a given hand, dealer's card and a set of table rules. The set of rules that affect basic strategy is always displayed at the top.

The source of the basic strategy tables is Michael Shackleford, the creator of the WizardOfOdds, which endeavors to be the most trusted and authoritative website about casino gambling.  

The strategies are displayed in three separate tables identified by the letter in the top left cell:

H - Player has a hard hand.

S - Player has a soft hand.

P - Player has a pair that may be split.

The top row indicates the dealer's card.

The left column indicates the total value of the player's hand for hard or soft hands, or the value of the cards in a pair.

You can control the app with the following gestures:

• Tap - Switch between strategies for Soft or Hard hand.

• Double Tap - Switch to strategies for Pairs.

• Swipe right - Cycle forward through the strategies for Hard hand, Soft hand and Pairs.

• Swipe left - Cycle backwards through the strategies for Hard hand, Soft hand and Pairs.

You can select the following table rules for the Blackjack Basic Strategy through the Settings menu:

• Number of decks - choose from 1, 2, or 4+ (four or more decks).

• Dealer hits on soft 17 - if selected, the dealer hits ace and any number of cards totaling six points (known as a "soft 17"). Otherwise dealer must stand on all 17.

• Double after pair splitting - if selected, the player may double after splitting a pair.

• No hole card - if selected, the dealer only gets one card, so there is no peeking for a potential Blackjack. Otherwise, the dealer gets a second card, face down.

• Surrender allowed - if selected, the player may surrender half of his wager. Otherwise, surrender is not allowed.
