Daily Dare Challenge is Kou-Jong. To beat AAA you need a score of 493 points and to beat Abigail you need a score of 156 points.
I was able to beat AAA after beating the first two levels on hard. I just kept resetting until I was able to beat the level. Beating easy and medium where not enough points.

prize for beating Abigail is The Kou-Jong Strategy (book). The
bonus prize for beating AAA or Abigail on the day the challenge is
released is Bamboo Flute. For beating the team challenge you get the prize of Traveling Game Food or Exploding Die.
