Do this in order
- 1
Print one Player Pack per team
Teams of 2–6 work best. Larger classes split into parallel groups with separate copies.
- 2
Prepare envelopes before class
The Host Guide packing map is step-by-step — no puzzle knowledge required until hints are needed.
- 3
Brief teams and start the clock
Hand over START packets. Offer hints only when a team is clearly stuck.
Avoid
- Do not pass out the Host Guide or solution sheets
- Avoid letting finished teams shout answers — use certificates for the reveal
When to download

Quick answers
Can I use one purchase for the whole grade?
The license covers one classroom. Print additional copies only for that class's teams.
What grade level fits best?
Independent reading level is roughly ages 9–13. Younger groups need an adult reader.
How long does the activity run?
Most groups finish in 45–60 minutes after 10–15 minutes of setup.
