How It Works
The constraint engine works by tagging each team's games and enforcing a minimum gap between consecutive slots. For 20 teams, this adds roughly 3 extra time slots to the schedule to absorb the rest requirement.
Step-by-Step Guide
Understand the constraint
"No back-to-back games" means no team plays in two consecutive time slots. For 20 teams, enforcing this adds roughly 3 extra buffer slots across the schedule.
Set your time windows
Define your game day(s) — start time, end time, game duration, and break length between slots. Wider time windows make it easier for the solver to satisfy the no-back-to-back rule.
Generate and verify
Click generate. The AI guarantees zero back-to-back violations. If it cannot satisfy the constraint with your time windows, it shows you the minimum adjustment needed.
Export the schedule
Download a PDF with rest gaps clearly marked, or export to iCalendar so every team gets automatic phone reminders for their games.
