Difficulty Rating System Description

Design a difficulty rating system for escape rooms:

Number of Difficulty Levels: [LEVELS]
Rating Style: [STYLE - stars/locks/skulls/custom]
Target Demographics: [DEMOGRAPHICS]
Room Types: [ROOM_TYPES]

For each difficulty level, create:

3. Recommended player experience level
4. Typical success rate percentage
5. Ideal group composition
6. Example puzzle complexity
7. Time pressure intensity
8. Hint usage expectations

Make the system:
- Easy for first-time visitors to understand
- Helpful for return customers to challenge themselves
