Basic rules of Blackjack

The hand with the total closer to 21 wins. If you go over 21, you bust and lose.
Number cards count as their number, and J, Q and K count as 10. An ace counts as 1 or 11, whichever is better for you.
Hit draws one card, stand stops drawing, and double down doubles your bet, draws exactly one more card and ends your turn.
Split divides your first two cards into two hands when they have the same value (10, J, Q and K count as the same), and you can split once. Split aces get only one card each, and a 21 after a split is not a blackjack and pays 1 to 1.
Surrender lets you give up after seeing your first two cards and get half your bet back.
When the dealer's face-up card is an ace, you can take insurance. When the dealer shows an ace or a 10-value card, the dealer checks for blackjack before the players act.
The dealer draws cards by fixed rules, and the result is decided by comparing the dealer's hand with each player's hand.

Table rules

The solo table uses 6 decks (312 cards), starts you with 1,000 chips and takes bets of 10–500 chips per hand. Blackjack pays 3 to 2 (a 100-chip bet wins 150 chips). The dealer stands on 17 or more, including a 17 that counts an ace as 11 (soft 17). Double down, split, surrender and insurance are all available.

Online tables start with 2 decks, and while waiting, the host can change the following settings.

Number of decks (1, 2, 4, 6 or 8) and starting chips (500–10,000)
Minimum and maximum bet, and the time limit per turn (15–60 seconds)
Blackjack payout (3 to 2 or 6 to 5; at 6 to 5, a 100-chip bet wins 120 chips)
Whether the dealer hits on soft 17
Whether double down, insurance, split and surrender can be used

Tips

If your hand is 17 or more, the risk of busting is high, so standing is the basic play.
When the dealer's face-up card is weak (2–6), the dealer busts more easily, so a good strategy is to wait rather than push your luck drawing.
When your total is 10 or 11 and the dealer's face-up card is weak, you can double down to go for a strong hand.
