A common form of tournament is Cup Americano, where you play doubles with different co-players in each match. Cup Americano is a fun, fair and social form of playing! Each player in turn meets each opponent in two matches. The games are played for example 32 points and the match can end like 32-0, 20-12, 18-14 etc.
It is also possible to play about 24 points or actually any amount of points. Keep in mind that it is good if the sum of points is divisible by four. (otherwise the players may not serve equally.)
The easiest and probably the best way to create a game schedule for Cup Americano is to use a program (online) like PadelCups.com to automatic generate an schedule and keep track on the results. It's free to create an account at PadelCups.com and to use the program for small tournaments.
