Blackjack is a common card game. It can have 2 to 8 players and requires a pair of 52 cards. Each card has a number and a suit. The goal of players is to try to use 2 to 10 cards to obtain higher points than other players, but not more than 21. The number of cards is determined by its number. Special cards (JQK) are considered as 10 points, while A can be considered as 1 or 11 points. After betting, each player will be dealt 2 cards, and can choose how many cards to take until they reach 21 or "stop". After each player completes the game, whoever has the closest 21 points will win all bets.
