@Roberta,
I can't seem to get Text Express 2 Deluxe to load properly, Roberta. I just tried two different sites and had the same problem at both.
I guess I'll stick to Text Twist. I did remember that you had talked about playing it many moons ago.
Sometimes I play Word Whomp or Boggle at Pogo.com but lately they've been causing my computer to crash. Any of the timed games, even Bejeweled 2, seem to sharpen my memory and concentration if I play them regularly, and I enjoy playing them, which is really the point. I do think these sorts of mental exercises do help.
