Who wants to play a game?
You can't use the letter that a person says you can't use in a sentence.
For example;
I can't use the letter "W" in my sentence:
I can do this game, right?
See?
You can't use "T".
And then, after you do your sentence, put a letter the next person can't say.
Don't use "T"!
Where you say the letter the next person can't say, you may use the letter you couldn't say in the sentence before.
Have fun!
