I found it more as a trial and error level. Not much logic in my opinion. Still, it was adventurous to find the right combination to get B to the win. Somehow you also managed to make an all grey structure look OK - probably the ample use of wedges. Thanks for the creation!
I agree w/@nGord and think that the "trial and error" feel is created by the enclosed structure. You just try all the entrances until one leads to the right exit.
@Don G Rowe - Thanks for siding with me. Say, what I do when I forget the stars is to copy my comment to the clipboard, delete it, and then paste it into a rating comment box. That way they stay together.
