the basic rule is this:
you name a word that starts with a certain letter. 


example:
A- apple. 



but....the big catch is that you must say a word starting with the following letter of the alphabet after the previous post. 
example:
A- apple
B- balloon
c- cat




it goes like that until you get to the letter z. 


then, you start over from the letter A.




that is how the game goes. enjoy. have fun.
