This is a really simple game. The premise, name five of whatever the category is. One person picks the category (the person that posts number five of the previous category) and each person after posts one numbered answer.
Eg: Name 5 Supercars
First person's response would be #1. Name of a supercar
and then the next person would be #2. Name of a supercar.. until we get five.
Then person with #5 would name a supercar then start a new category.
