Create my party kitDetective Mystery party, personalized
Your child leads the case. Add your child's name, guests, and what went missing — we personalize a full mystery kit: suspects, clues, a case file, and a reveal.
Plays like an indoor scavenger hunt. Every clue uses your child's real name and points to the next hiding spot instead of a random object.
No acting, no entertainer. Two detective teams, five suspects, a trail of clues you hide at home — print it and the game runs itself.
Works for any mixed-age group. Kids 6 to 12 stay equally hooked, all the way to the reveal before cake.
A peek at the case file
“Detective [Child], the [Town] Precinct needs you. Someone swiped [item] minutes before the party started, and five suspects were in the room. Question them, follow the clues, and crack the case before cake.”
How it works
Three steps from "I need a party idea" to "press print".

Questions, answered
How does a detective party game work for kids at home?
You enter your child's name, their guests, and what went missing. We personalize a full mystery — suspect cards, clues, a case file and reveal script — into one PDF you print at home. Hide the clue cards where the setup guide tells you, and the kids do the rest.
What ages is this detective birthday party idea best for?
Ages 5 to 12. Younger detectives can have the clues read aloud, and most kids 8 and up read and solve the case entirely on their own.
How many kids can play the detective mystery game?
Anywhere from 4 to 16. The kit automatically splits your guest list into two detective teams so every kid gets a role in solving the case.
Can I use this as an indoor scavenger hunt if it's raining?
Yes. The whole game is built to be played indoors — hide the clue cards around your living room or apartment just like an indoor scavenger hunt. The story and reveal work exactly the same either way.
Do I need any special equipment or an entertainer?
No. Just a printer, some paper, and about 15 minutes to hide the clues before guests arrive. No login, no app, and no entertainer to book.
Looking for a different theme?
Three more mysteries, each personalized the same way.

🏵️Alice in Wonderland
A birthday mystery for big kids, ages 5 to 12 — not a 1st birthday “Onederland” party. Your child leads a curious cast of characters through clues to catch the culprit.
