UPDATE:
We purchased it the other day, and we're very happy with it.  Lots of fun, very good graphics.  One slight beef -- a couple of the puzzles, of the dozen-or-so we've played, have been inferior to what might have been used on the show.  For instance, a table standing for the word "able".  But that's a small beef.  This is fun, and 20 bux well spent.
I also changed the music to the Narz "Concentration" theme.  Much better!  And thanks for the directions.
