The Posting Key is different from the Master Key, and Active key. Make sure that you're using the right key.

Ok thanks, I will try.

No way! I put the posting key as it asks me and the Hive user name and I solve the puzzle but now it does not give any answer, is it because I am doing it from my cell phone? Is a previous registration required? I have not registered, I just entered the link and it asks for user name, posting key and solve the puzzle. What am I doing wrong @fulltimegeek ?

After you solve the puzzle make sure to press "Send Answer" at the bottom of the screen. You may have to scroll down to see it. There is no registration for this game.
