There are more than 1,200 types of Thai traditional games.
 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.
 For example, sand, mud balls, khan kluay (The stem of the banana tree) were components of games.
 This use of raw, widely available materials makes Thai traditional games easy to play.
