Print-at-home mysteries for 1 parent + 1 child · ages 8–10

A mystery you can only solve together.

You get one page. Your child gets the other. Each page holds clues the other person needs, so you talk, listen, and crack the code as a team.

Free 3-page mission · No card needed · No cutting or prep · Black-and-white OK

This is what you print

Real pages from the free mission. The child's clues and the parent's clues are on separate pages, so you really do need each other.

Not just another puzzle sheet

Two pages, two real roles

Your page and your child's page hold different clues. Nobody can solve it alone, not even you.

Your child leads, too

Kids give directions, share clues, and explain what they notice. You're a teammate, not the answer keeper.

Zero prep

Print two pages and grab pencils. No cutting, no timer, no game-master setup. Hints and answers are in the parent guide.

How it works

1. Print

Print the child page and the parent page. Black-and-white is fine.

2. Split the clues

Your child takes their page. You take yours. Don't peek!

3. Talk it out

Read your clues out loud, ask questions, and piece it together.

4. Crack the code

Write the 3-digit code together, then check the answer in the guide.

Questions parents ask

What is it, exactly?

A printable mystery for one parent and one child. You each get your own page with different clues. To crack the code, you have to share what you see, listen to each other, and solve it as a team.

What ages is it for?

It's designed for kids ages 8–10. Younger kids can join in with more reading help from you.

Can two kids play?

It's built for 1 parent + 1 child. With two kids, they can share the child page and swap roles after each mission.

What do I need?

A printer, plain paper, and pencils. Print on US Letter at 100% (on A4, choose “Fit to page”). Black-and-white works. No cutting, no timer, no extra props.

How long does it take?

There's no timer. The free mission has three short missions, and you can take a break between any of them.

Is the free mission really free?

Yes. It's a $0 checkout: enter your email, and the download appears right away. No card is needed.

What if we get stuck?

The parent guide has step-by-step hints and the full answers, so nobody stays stuck. Check the answers only after you play.

Do you collect information about my child?

No. Only the parent checks out. We never ask for a child's name, age, or photo.
