Thirty-One is a time-honored card game that artfully blends strategic thinking, a touch of luck, and refined skills. Usually, a standard 52-card deck is utilized for this game, and the main objective is to assemble a hand that sums up to a value as near to 31 points as possible. At the start, each player is given three cards face down, and the rest of the deck is positioned at the table's center. In turn, players can either draw a card from the deck or the discard pile and also have the choice to exchange a card in their hand with one from the discard pile. A round concludes when a player decides to "knock," signifying that they think their hand is the closest to 31.
