15 Mode is turning all 15 entities on at once. I'm not going to list every entity, but I will list the challenges.

- Classrooms 15 Mode
- Library Rooms 15 Mode
- Bathrooms 15 Mode
- Dark Rooms 15 Mode
- Pool Rooms 15 Mode
- Play Rooms 15 Mode
- Kid Rooms 15 Mode

15 Max Mode, is most likely impossible. 15 Max Mode is turning on all 15 entities, and enabling every ability (enable walk on walls and break doors instead of open door). You can try your hand at this, but it will not be easy.

- Classrooms 15 Max Mode
- Library Rooms 15 Max Mode
- Bathrooms 15 Max Mode
- Dark Rooms 15 Max Mode
- Pool Rooms 15 Max Mode
