visually if you only just stare at the puzzle for some minutes, it just can sometimes look like a pattern exists.  many others have commented about it on this thread in the earlier pages but it is just misleading to actually think that a real pattern exists.  what i was actually trying to say.  like i just find it fascinating how it looks that way even with some of the past solved puzzles but then when you start writing the code yourself and trying different things, you begin to quickly realize that it really only comes down to brute force searching and alot of waiting or good luck.
