somebody asks a question. they also name a letter. you have to answer the question without using the named letter. then you set the next question and also name a letter
Unavailable Letter

*i'm still trying to figure out how this game goes
Everyone seems to be doing different things.
You simply answer or respond to the question. But every question comes with a condition, that you cannot include a specific letter in your response.
ie, Q) Do you like ice-cream? If so why? n
The letter n at the end tells us, whatever we include in our answer to the question, none of the words must contain the letter n.
So a response could be:
A) I like ice-cream of all sorts, they are a lovely way to help you relax after a difficult day.
^^^^ There are no letter n's in that sentence.
An unacceptable answer would be :
A) I don't like ice-cream, it gives me a migraine.
Hope this helps!
