The idea of the game, as the name implies, is for the first reply to change one letter of the word creating a new word. The next reply should then change one letter of the new word creating another new word and so on. The purpose is to see how long we can keep this thing going and to see what word we end on.
For Example:
Poster 1: Duck
Poster 2: Muck
Poster 3: Yuck
Etc.
