Okay more hints... SKIP THIS POST IF YOU DON'T WANT ANY HELP...
1) Don't think of the dice as numbers!
2) 2/3 of the dice don't contribute to the score.
3) Draw a picture of a flower - concentrate of the main parts of the face.
4) Pay close attention when the correct score is a 0, 10, or 20.
5) Outside the tallying of scores, there is no math.
6) Once again - name of game is BIG hint.
I like this "frustrate 'em more" approach

I can see the responses now:
1) Well, if they're not NUMBERS, why use dice?
2) If you're keeping score, numbers HAVE to play into it. And 2/3? FTW?
3) If I could draw a picture of a flower, I wouldn't be so good at math. A flower has a face?
4) Again with the "score". Dude, you're messing with me, it's GOTTA be about math and counting.
5) Liar. I can tell because your pants are ablaze.
6) Dude, if that helped me the FIRST time, I wouldn't still be trying to figure it out! This sucks, and you all are big fat liars who figured out the mathematical equation or algorithm this thing uses and I hate you all. Die, die, die. Big flaming deaths. Your level of suckitude is beyond comprehension. I can't believe none of you wil.......hey, I
GOT IT!
