Very fun game from another forum.
Works like this: one person hides the diamond to keep it safe, then the next person has to think of a way to get it and then hide again!
Example:
Person 1: I throw the diamond in the ocean.
Person 2: I hire a submarine to fetch it. I then hide it inside a whale.
Person 3: I harpoon the whale and get it out. I then throw it into a volcano.
Etc. Etc. Get it?
Ok I'll begin:
I surround the diamond with mines.
