Bai Dổi Thưởng, often referred to simply as “bai doi thuong,” is a type of gambling game that has become a staple in Vietnamese society. Originating from Chinese roulette games, this entertainment option has developed its own distinct characteristics over time. Players can find it in almost every corner of the country, from bustling streets to cozy cafes. The game involves spinning a wheel and predicting the outcome based on the numbers or colors displayed. Participants can bet on specific outcomes, and winning combinations are determined by the rules of each variation. One of the most famous versions is called “Xuat – Nhập,” where players can either bet on a single number or a combination of numbers. The rise of Bai Dổi Thưởng has been accompanied by its integration into everyday life in Vietnam. From small-scale operations to large-scale establishments, the game has become a social phenomenon. It attracts people from all walks of life, including students, professionals, and retirees. Despite its widespread popularity, Bai Dổi Thưởng also poses certain risks. Issues such as addiction, financial losses, and social conflicts have been reported in some cases. Efforts to regulate the game are ongoing, with calls for better supervision and public awareness campaigns about the potential dangers of excessive gambling. For many Vietnamese people, Bai Dổi Thưởng represents more than just a game—it’s a reflection of their culture, history, and evolving entertainment preferences. As it continues to evolve, the game will undoubtedly remain a significant part of Vietnam’s social fabric.
