The scoring in padel is similar to tennis, however, there are several distinctions between the two games. Shots may be played off the walls of a padel court, much as in squash. In addition, in contrast to tennis, a served ball must bounce once on the ground and then be struck from below or at waist height. Players have two chances to strike into an opponent’s box while serving. A set is won when a side wins six games and the differential is at least two games; otherwise, the set is decided by a tie-break. The best of three sets format is used in the matches.
