In each round a master list of bigrams is created for all players to use. Players try to think famous people, real or fictional, with initials matching each bigram on the list. Players score one point for a valid answer that matches another player, two points for an answer with no matches, and three points for answer in which no other player can think of any answer for a particular set of initials.
A common way to create a master list of bigrams is to write the letters A through Z in the left column (first name initials) and the first 26 letters of some quotation or saying in the right column (last name initials).
