还是不明白（feeling stupid *_*），能不能进来看一下1. what is the third color? Green? 2. how to find the key with the third color? (consider the name of this level, 9balls, go back and find the KEY) 6, been the green ball? 3. how to read the hidden message using that KEY? (how to locate sth in a table) Still cannot figure out why even after i found spoiler answer.

第6关怎么过?
