The season is like this:
Groups of 6.
You play 5 games.
Then you play 3 games against teams of other groups in your conference level who are in the same position than you (if you finish in 1st position after the first 5 matches, you'll play against the first teams of the other groups in your conference). You don't know your rivals until the end of day 5.
Then you play the other 5 games against your group members.
Finally 3 games with teams of other groups in your conference (same position). You don't know your rivals until the end of day 13.
Once the regular season is over, Play offs begin. Every one will play games until the very end of the season to determine positions 1-24. Each round will be best of three (third game is always played, no matter if anyone won the first two games), but the last round, that's only two games, basket average can decide the winner.
Official games are player Mondays, Tuesdays, Thursdays and Fridays.
Friendly games can be played Wednesdays and Saturdays,
