Here is some info for round robin draw generator, hope this kinda helps get the juices flowing.

Area's for creation/settings and customization:

-Leagues

-Games

-Rounds (Round 1, 2, 3, 4, Etc)

-Divisions (A, B, C, D, Etc), should be set for each league

-Teams

-Sheets (Names vs Numbers)

Things to adjust when wanting to create a draw/generate games:

-What League do you want to generate a draw/round for?

-Which Round is it?

-Which Teams are in Div A, Div B, Div C, Etc as applicable

-Which Sheets are used

-What Day(s) of the week are the games

-What Time(s) each day are available for the games

-What's the day of the first game

-What date(s) are excluded/skipped when generating games

-How many round robin cycles would you like

-Should the teams playing order be shuffled at random

-Should the games/teams be on a balanced mix of sheets

-Should the games/teams be on balanced times (Aka early vs Late)

-Does one game time get priority (Aka fill Early before making any late games)
