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.
Help us find the tricky bits.
US parents and guardians: try the sample with your group and tell us your setup time, the hints you used and anything confusing. See the adult testing instructions. Taking part is optional; the sample is free for everyone.
