We start off with a four letter word. Then, the next person changes one letter, to make a new word. And so on and so forth. You cannot add extra letters or take away letters. If someone posts with a word that is not four letters, ignore their post completely. Also ignore the post above you if they changed more than one letter, or used an imaginary word.
Example:
P1: Boat
P2: Boa
P3: -ignores P2- Coat
P4: Coal
It's a really fun game, and you will be surprised how much a word can change! We start off with:
Coke
