A mission for the players
Put the party guests in order, decode a delivery label and follow a number trail. Each clue reveals a digit.

A little backup for you
A quick setup guide and two hints per clue. Offer a nudge whenever your detectives need one.

The big little reveal
Check the answers and read the envelope’s birthday message aloud. There’s space for your feedback, too.
FOR THE GROWN-UPS
Less setting up.
More figuring
things out.
Print one page. Keep two nearby.
Print page 1 on US Letter paper. Give the players a pencil. Keep the hints and answers on your screen, or print them separately. You don’t need a real envelope, lock or hidden objects.
A short sample, made for trying.
We’re exploring mysteries for ages 8–10. This early sample is still being tested for difficulty and playing time, so keep an adult nearby. It’s a small taste of a mystery, rather than a full party activity.
Tell us where you got stuck.
If you received an invitation from us, reply with your setup time, the hints you used and anything confusing. Please leave out children’s names, photos and recordings.
