Logic Quiz was great fun

I received this message from my American friend,

Kin Lian: I concluded the Einstein quiz and it was great fun. I glanced at your method and picked up an important hint, so I can't say I did it all on my own - but I was headed in the right direction. I've also done your "four house" quizzes, which were quite enjoyable. I will try the fives and sixes after that. They really are a lot of fun and keep the mind spinning!!

Here is the link to the Logic Quiz (also Einstein's quiz):
