The game where you make new words by changing one letter from the previously posted word.
In addition, if it will create a new word, you can add or subtract a letter without changing any of the letters there previously. 

For example:
person 1: bend
person 2: lend
person 3: land
person 4: lard

and so on and so forth.

4-letter words tend to work best. 

I'll start the game off! Your word is:
