or "King of the Court" where play is 1 vs. 1 with the third player remaining in the back court out of play while the other two play a rally; the rally winner then serves to the player who was sitting out, and the rally loser stays out of play. Another three-player variation is "Sevens" in which one player plays against two players as a team, with the game being played to seven points; if the two player team gets to seven first, the game is over, but if the solo player gets to seven first then the game continues to 14; if the solo player again reaches 14 first, then the game continues to 21, where the game ends regardless of whether the solo player or the two player team reach 21 first.

Most players use an offensive serve for the first serve, and a defensive serve if they need to hit a second serve. Of the offensive serves, the most common is the drive. The intention with this serve is for the ball to travel low and fast towards either back corner, and to bounce twice before striking either side wall or the back wall. If the opponent is adjusting to the drive serve, the server will throw in any variety of jam serves. A jam serve is an offensive serve which attempts to catch the opponent off balance by making use of difficult angles and unfrequented play space. The most common jam serve is the Z-serve, which strikes the front wall close to a side wall. The ball bounces quickly off the side wall, then strikes the floor and then the opposite side wall about 30–35 feet back. Depending upon the spin the server gives the Z-serve, the resulting carom may prove unpredictable and difficult to return. Side spin may cause the ball to bounce parallel to the back wall. A pinch serve is similar to a drive serve; however, the ball strikes a side wall very low and close to the serving box. With the appropriate spin, the ball has little bounce, and is difficult to return. It is possible that a successful serve would strike the sidewall before the short line, and land on the floor after the short line. If the
