Blackjack is a popular casino card game in which players compete against the dealer. The goal is to reach a hand with a total value of 21 points or as close as possible, without going bust. Each card has a value: numerical cards maintain their value, face cards are worth 10 points and aces can be worth 1 or 11, depending on what suits the player best.

At the start, the player is dealt two cards and can either "hit" (take another card) or "stop" (keep his hand). If you exceed 21, you automatically lose ("bust"). Whoever has 21 or is closest to this number without going over wins, and in the event of a tie with the dealer, the bet is returned to the player.
