Blackjack

If your first two cards add up to exactly 21 (Ace + 10 or face card), it's a Blackjack.
It normally pays 3:2 (you win 1.5 times your bet).
Win automatically, unless the dealer also has Blackjack (tie).

When all players have finished:
The croupier reveals his hidden card.
You must order cards until you reach 17 or more.
If the score goes over 21 → all players who did not go over win.

You can choose:
Request (Hit) → receive another letter.
Stand down → not to ask for more cards.
Double Down → double the bet and receive only one more card.
Split → if you have two identical cards (e.g., 8 and 8), you can separate them into two hands.
Surrender (in some casinos) → lose half of the bet and end the hand.
If you exceed 21 → you automatically lose (Bust).

The player places his bet.
The croupier deals:
2 cards to the player (face up).
2 cards for him (one face up and one face down).

Cards from 2 to 10 → are worth their number.
J, Q, K → are worth 10.
As (A) → can be worth 1 or 11, as appropriate.
Example:
A + 10 = 21 (Blackjack!)
A + 8 = 19
A + 8 + 5 → the Ace is worth 1 (total 14)

To get a hand whose value is as close to 21 as possible, without going over, and beat the dealer.
