Amazingly good.  See the details from Brenda on the teaching page.  I created two sets of cards – one with questions and the other with the “points” including Typhoon cards.  The distribution is shuffled and random.   The points card is drawn after the team has answered correctly.  It’s great fun – especially when the team in front loses all their points to the typhoon.  Slightly different rules to the ones I used can be found on the GenkiEnglish site.   I think I’ll change the rules each time just to keep them on their toes!.
