You can find a list of quickstarts at https://github.com/TimefoldAI/timefold-quickstarts.
Examples include:
- School Timetabling
- Employee Scheduling
- Conference Scheduling
- Flight Crew Scheduling
Metaheurstics are also very useful for puzzle games; you can quickly run a metaheuristic to generate a difficult but solvable puzzle in less than a second, while only being about 20 lines of code without libraries (but as your scale increases to hundreds of different pieces, you probably want a library so you can use their incremental calculation).
