Thirty-One is a game with a long and respected history in the realm of card games. It ingeniously combines elements of strategic thinking, a hint of luck, and refined gaming skills. Typically, a standard 52-card deck is employed for this game. The primary goal is to assemble a hand whose total value is as close to 31 points as one can achieve. At the beginning of the game, each player is dealt three cards face down, and the remaining deck is placed in the center of the table. In turn, players have the option to draw a card from the deck or the discard pile. Additionally, they can choose to exchange a card in their hand with one from the discard pile. A round comes to an end when a player decides to "knock," indicating that they believe their hand is the closest to 31 points.
