These games originated in the era of the Sukhothai Kingdom (1238-1438).  Hundreds of years later, during the reign of Rama VI, the games grew popular again among Thai children.  The original purpose of Thai traditional games was to form good relationships between adults and young people, and for entertainment, relaxation, and exercise.  In that period, children's games were played with songs and rules to make them more entertaining.  They are designed to allow players from a range of socioeconomic statuses, as most traditional Thai games utilized raw natural materials.
