A set of unused items from a SpyCo birthday, including a complete set of unused clues, four clue booklets, five "ID" stickers and parent instructions. I have checked and the website passwords to the videos all still work. (At https://www.spyparty.co.uk/ ) You wouldn't be able to get a "Call from Octagon" but you could set this up with a friend. (Extras are because we had to order 2x sets as it was a larger party, but only used 1x set of clues.)
The party is for 6-9 year olds.
