Game Stats

Words with Friends tells me that I have played 100% of 2 letter words, but only 90% of 3 letter words. 

The game doesn't let you play 1 letter words - not even on the first move. 

I think we only have 3. 

A, I, and O. No U or E. 

Update: on reflection, each letter is its own name, and is a word in that way. But A, I, and O all have a separate word. 

Calling Z a word because it's the name of a letta,

Seems kind of meta.
