Team play in blackjack involves a group of players collaborating to improve their chances of winning against the casino. In this approach, team members use strategies like card counting and sharing information about the deck's composition to make more informed betting decisions. While individuals may take turns playing at the table, the group operates cohesively to maximize bets when the count is favorable and minimize losses when it's not. Communication is often subtle, with signals or pre-arranged codes to indicate betting strategies.
