From the page Start all applets can be accessed. During the initialization of an applet you are asked to verify a certificate. You only have to accept this certificate if you want to save schedules in csv-files. All other features can also be used without accepting the certificate.
In each applet the number n of teams is set by a slider. After pressing the button "Init" the complete graph Kn is drawn (cf. the graph model for sports tournaments). Schedules are represented as edge colorings of the Kn. Additionally, schedules can be generated in different formats:rounds, breaks, groups, complementary teams).
Tables without colored entries can be saved on your computer as csv-files.
