Simple Project - Blackjack

  • 遊戲中只有player 與 dealer
  • dealer 在最後點數⼀定要⼤於 16,若⼩於16 則要發卡片到滿⾜條件為⽌
  • 如果player⼿中有5張牌,且點數沒有超過 21點,則稱為 Five Card Charlie,則直接獲勝
  • J Q K 視為 10點
  • A 可視為 1 或 11點
  • A + J/Q/K 稱為 Blackjack
  • 因為排組沒上限,要留意也許會出現 2 張以上的 A 在排組中,總和可以視為 2 或是12

  • If the player is dealt an Ace and a ten-value card (called a “blackjack” or “natural”), and the dealer does not, the player wins and usually receives a bonus.
  • If the player exceeds a sum of 21 (“busts”), the player loses, even if the dealer also exceeds 21.
  • If the dealer exceeds 21 (“busts”) and the player does not, the player wins.
  • If the player attains a final sum higher than the dealer and does not bust, the player wins.
  • If both dealer and player receive a blackjack or any other hands with the same sum called a “push”, no one wins.
  • If player get 5 cards without busts, player wins automatically(extra).
