Lines may need to be drawn in the sand. Each team will be allowed a maximum of four substitutions on the roster. Substitutions will be limited to four per game.
Free substitution is at the server's position.
Free substitution is male for male, female for female, at the time of gained service, replacing the next server. Matches will be played best-of three games. Game times may be changed as long as it does not hold back the next scheduled game for either team. A game shall be played to 15 points with a cap of 18 points. The winning team must win by 2 points, except with the score tied 17-17.
