This is a quick-and-dirty scheduler for groups of people playing doubles in badminton (or similar sports). It's designed for casual groups of friends playing together informally, rather than as a tournament scheduler.
Enter at least four names into the text field below, separated by spaces, and hit "Create schedule". You can optionally specify the number of games to play and/or whether or not you want to see games-played statistics.
A schedule will be generated automatically which does its best to ensure that everyone sits out in turn (if required), and that everyone plays with/against different partners as regularly as possible.
