About this game
A Murder at Sunset Chateau
The game builds a new murder mystery every time you play.
✓ Every case features 8 suspects selected from a cast of 37+ Hollywood guests.
✓ A new murderer is determined every game.
✓ Motives, relationships, evidence and contradictions change.
✓ No two investigations unfold the same way.
Everyone at Sunset Chateau has something to hide.
Question suspects, compare alibis, and untangle a web of contradictions, hidden relationships, and dangerous motives.
Every conversation reveals another piece of the truth—but the killer is counting on you accusing the wrong guest.
Use observation, interrogation, and deduction to uncover the murderer before they disappear into the night.
Some will lie to protect themselves.
Some will protect each other.
One of them is a killer.
Investigate the Truth
Question suspects who lie, deflect, contradict each other, or protect dangerous secrets.
Follow the Evidence
Use the Strategy Board to visualize the relationships, contradictions, motives, locations, and timelines surrounding the investigation.
Every Case Is Different
Every investigation is procedurally generated with:
• A different murderer
• Different motives
• Different suspect combinations
• Different relationships
• Different evidence
• Different contradictions
Every new case creates a different path to the truth.
Think Like a Detective
Built for players who want to think like a detective—reading people, testing theories, and committing to a conclusion.
Weigh motive, means, and opportunity before making one final accusation.
Make the Final Accusation
When you believe you have solved the case, identify:
• The killer
• The motive
• The murder method
• The critical timeline
• The crime scene
Choose carefully.
A wrong accusation could condemn the innocent while the real killer walks free.
