Rule: Think of a noun that relates to the noun posted above you. Bear in mind it has to be a noun. It can be related in any way, like same colour, same category, opposites, etc. Just make sure it's not too far-fetched.
Example:
Harry: Hermione
Ron: know-it-all
Hermione: encyclopedia
Luna: WalkingEncyclopedia!
Ginny: Minitokyo
Draco: forum
Neville: Internet
And so on and so forth. Got it? De wa, gēmu o kaishi shimashou!
