Happy Birthday, Somebody's Dead

A Birthday Party With One Murder and Zero Prep

The best birthdays have a story. Make yours one where everyone's a suspect.

ACT I
Pick Your Vibe

Birthdays by Age

Kids (ages 10+)

Family-friendly mysteries with silly motives and zero gore. The prime suspect is the substitute teacher, not a murderer.

Teens

School-setting whodunits. Drama over danger. Perfect for sleepovers and quinceañeras that want a new kind of centerpiece.

Adults

Noir, scandal, dinner-party stakes. Where the wine is good, the outfits are better, and the alibis are worse.

Mixed ages

Family-friendly mysteries work for 8-to-80 tables. Everyone from the grandkids to the grandparents plays the same game.

ACT II
The Invitation

Send This With the Invite

Drop these lines into your birthday invite. The anticipation is half the fun.

Dress code: whatever your character would wear (details coming)

You're arriving at [the setting]. Someone won't leave alive.

You'll get your character, your secrets, and your motive on the night.

Don't tell the others what you know. Some of you are lying.

Before You Send the Invite

What ages work for a murder mystery birthday party?
Mysteries exist for 10+, 13+, and 18+. You pick the tone during setup — family-friendly, teen-appropriate, or adult intrigue.
Do I need a fancy venue?
No. A dining room or living room works perfectly. Some hosts dress the space with a theme — black-tie, 1920s speakeasy, Clue-style mansion — but none of it is required.
Can the birthday person be the victim?
Yes — and it's great. Everyone accusing each other of murdering the guest of honor is a genuine party highlight.
Can I pause mid-game for cake?
Yes. Phases pause on the host's call. Cake, presents, bathroom breaks — the investigation waits for you.
What if a guest doesn't want to act?
They don't have to perform. Characters are played as yourself-reading-clues — shy guests love it because the mystery carries the conversation.
How many guests?
Between 4 and 20. 8-12 is the sweet spot for a birthday party.
