Don’t worry, we have all of yourimportant lines written out on the Whodunnit App. You just focus on making sure you and your guests havea good time!

  5. Download character packs if you have more guests than the theme’s default number.

  6. Add event details, time and date, and location. Tap on the checkmark to create the game.

  10. Don’t forget to prepare for your role! Read the information about your character to understand their motivation and why they might be the murderer. Get your costume together, some suggestions included in the Whodunnit App.

  11. Print out Voting sheets for each guest.


Note: Do not unlock any cards until the fateful night. Don’t read Introduction, Announcement, Investigation, and Conclusion. Reading ahead will only spoil the mystery.



When the guests arrive, it’s a good idea to gather everyone to introduce themselves to the group, sharing their names and perhaps one or two background details.


Once introductions are made, head over to Round One and select "Introduction" and unlock the “Secrets & Objectives” cards from your device.


Read the card marked “Introduction” to the room. This will get the party started! Don’t forget to unlock the “Secrets & Objectives” cards.

4. Read the announcement card. By the time you finish reading it, the victim will fall to the ground, dead! If they don’t, gently encourage them by saying something like “Oh no! Someone is dying!” (If nobody falls to the floor, move on to the card “Investigation” in Round Three to find out who dies.) Don't forget to unlock "After the Murder" Objectives
