Teams
A sepak takraw game is played between three regus, or teams, each regu consisting of three players and one substitute. Each game is composed of three sets in the same manner as badminton. Only three players from each side are allowed inside the court during play but a substitution can be called anytime during the game. However, once a substitution is made, no further substitutions are allowed for the duration of the game.
In a formal competition, there are two kinds of matches: the regu competition and the team competition. In a regu competition, two regus play a game consisting of three sets and the regu with the mosts sets won is declared the winner.
A team competition is more complicated. Each team fields three regus so that a sepak takraw team has a total of 12 players. The first regus of each team will play a three set game and the winning regu earns a point for its team. The second regus of each team will then play and the winner of this second game will earn a point for its team. If the winner of the first and second regu games belong to the same team then the match is finished and the third regus need not play. If however, the winner of the first regu game is not the same team that won the second regu game the third regus will play for the deciding game.
The regu competition is most often played during local events and during physical education. However, in a larger event the team competition is generally preferred.
