Blackjack is the most widely played casino banking game in the world. The game is also knows as Twenty one (21).
The idea of the game is to have a better hand then the dealer, which can be done in a number of ways:
Get 21 points on the player’s first two cards (called a blackjack), without a dealer blackjack;
Reach a final score higher than the dealer without exceeding 21; or
Let the dealer draw additional cards until his or her hand exceeds 21.
