If you know tennis you already know the score. The padel game runs on 15, 30, 40, game, with deuce and advantage when it is tight, and six games takes a set — see
the padel rules for the full breakdown. The one big difference is the serve. You bounce the ball behind the line and hit it underhand at or below your waist, so nobody is firing 200kph aces past you. Serving is about starting the rally, not ending it, which is exactly why a first-timer is never left standing there watching the ball go by.
