I should have read this thread earlier!
I got it last night and when I first tried it, I got 80! I just couldn't get "Blue" to work: "Blue!", "Bloooo!", "Bah-looo", "Buh-looo", "bloo" (fast), "bloo" (slow), trying all sorts of accents I could muster.

Once I yelled Blue when it was the word "Blue" written in "black" and it took it...

I was starting to wonder if some weird franco-ontarien accent-thing was creeping out. I wasn't saying "Bleu" maybe after a while it sounded like "BLUE! BLUE! BL-tabarnacle-d'estie-callisse-de-cochenerie-mal-sale-OO!! BLUE!!! BLOO!!!!!!". :P
After that I vowed not to use the speech recognition. After a try with the "I can't speak freely" section, I managed to get 23, which I guess isn't bad, but it didn't record it since it only allows it once a day.

Mind you, I guess I could have just restarted a new user then, it's not like I had played for long. :P
Anyway, I tried it when I got up this morning (and still a little groggy). I managed to get 32.
Heck, didn't even get a huge "HEY! You impoved by 48 points! Holy crap!" message from the doctor.
My first attempt at Sudoku confused me as well. I started the first puzzle, and finished the first row and first column of squares. I was in the middle of doing the middle square when it just stopped and told me I cleared it? Was it because I've reached a point when there was only one possible solution for each square? If so, I'd still like to be able to complete the whole thing myself at least once in a while.
All in all, it might be interesting to play a bit every day, granted my fiancee is bored with it and wants Tetris back in there. :P
