About this system
The Secret Agent Mission Kit - The Party Box
Not a list of party games - a STORY. The mysterious Agent X has hidden the legendary Birthday Treasure somewhere in the house, and your agents must crack real coded messages, solve riddles and pass field challenges to reach it. Twenty five to forty minutes of mission, and the birthday kid is the hero of it.
The Real Cipher
Every agent gets a cipher card. The three intercepted messages are printed in actual code - kids decrypt them letter by letter, and the rush when the first word appears is the whole party. (Handler gets the full answer key. Obviously.)
How The Mission Runs
1. Read the Mission Briefing aloud - HQ has intel, Agent X has been here
2. Agents decode Message 1, which points into the house
3. Each station hides a field challenge plus the next lead: riddle, code, riddle, code
4. The final message leads to the treasure - and Mission Accomplished certificates
What Is Inside
- Mission Briefing letter (read aloud - it almost self destructs)
- 6 Agent ID badges with code names and clearance level
