Case files for curious kids
Classified Cases are mail-order mysteries for kids 7 to 13. Sealed evidence arrives in boxes and envelopes over eight to ten weeks, and your detective works the case on its own police computer: logging clues, filing reports and, finally, naming who did it.
How it works
Four steps from the first box to the moment your detective names the culprit.
Choose the mystery that suits your kid: a gentle alien rescue for younger agents or a museum heist for seasoned sleuths.
Box 1 brings a credential card with their own login, the first sealed evidence, and a welcome letter from the boss.
They sign in to the case's own portal, log each clue by its code, dig through records and file a short report each week.
Every accepted report unlocks the next step and sends the next delivery. The final report names the culprit and earns a reward box.
Open cases
Each case is a complete story with its own boxes, its own characters and its own portal.
Something crashed in the fields outside town. Something small walked away. Find it before anyone else does.

A priceless sapphire. A perfect fake. Eight weeks to find out who made the swap.
Inside the box
Every delivery is packed like a real evidence file. Nothing is decoration: each item is a clue, a tool, or a reward.
Labeled with real item numbers they log in the portal.
Letters, maps, receipts, schedules and photos that hide the details that matter.
UV lights, test kits and lab samples, packed for the week they're needed.
A badge number and access code printed on a card. No email address needed.
The Chief (or HQ) writes back as the case moves, so it feels alive.
Solve the case and a final box arrives with a keepsake for the shelf.
The case portal
Every case comes with a private portal built for that story. Kids sign in with the badge number on their credential card and get to work.
What they practice
The answer is always in the documents, if you read every line.
Rule people out, test theories, and spot the alibi that doesn't add up.
Times, names and codes pile up. Good detectives write things down.
A hunch isn't enough. Every report needs evidence to back it up.
Parents' corner
A parent view runs alongside every case. Peek at hints when they're stuck, see the full solution, track every shipment, and turn on the lab speed-up if waiting isn't fun.
Questions
Our cases are written for kids roughly 7 to 13. Each case lists its own age range and difficulty: Starter cases use tap-to-answer missions and plain words, while Intermediate cases expect confident reading and typed answers.
Box 1 ships soon after you order. Each later box or envelope is triggered by your detective's progress in the portal, so it arrives when they're ready for it rather than on a fixed date.
When a report isn't right, the portal explains what to look at again. In-story help is available in the portal, and your parent view has a ladder of hints plus the full solution.
No personal information. Detectives pick a codename from a list and sign in with a pre-printed credential. We store their game progress (logged clues and report answers) only to run the case and show it to you.
Gifting
Ship a case straight to a niece, grandson or godchild with your own message. Instead of one moment on a birthday, they get weeks of mail with their name on it.
Launch dates, early-bird offers and the occasional printable puzzle. For grown-ups; we never email kids.
