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.
