I have played many games, But, you give no vowels. Several times the entire play area was covered in letters but only 1 vowel in the whole tank of letters. This really could be a fun game. As it is right now, I don’t see any reason to play.
I gave it another try, still you just sit there watching the tank fill with letters and zero vowels. I don't know of many words with no vowels. I guess this game is a waste of time. No fun.
