Odd Number of Teams
If you have an odd number of teams and you want to give no more than one game per week, you can give bye weeks by reducing the number of games.
Example 1:
7 teams playing 6 games in 7 weeks
––> this will give each team one Bye over the course of the season.
Example 2:
5 teams playing 8 games in 10 weeks
––> 2 byes per team
Example 3:
11 teams playing 10 games in 11 weeks
––> 1 bye per team
Alternative: even out odd divisions with a dummy team
If you need a different number of weeks, you can also add a team to get to an even number of teams (name it BYE or something like that) and simply set the number of games = number of weeks (i.e. giving each team 1 game per week).
In PRO, you can create a team constraint that blocks everything, so that byes remain unscheduled and don't take up any time slots. Click 'Add Team Constraint', select the BYE team and nothing else, click 'save'. It will say 'invalid constraint' because it blocks everything, but that is what you want in this case.
Even Number of Teams
If you have an even number of teams but – for whatever reason – you can't have all of them play each week, you'll need to increase your number of weeks or decrease your number of games accordingly.
Example 4:
8 teams playing 6 games in 8 weeks
––> this will make 3 games each week, i.e. two teams will have a bye each week
