HAH! Never mind. Just figured it out. Bloody simple. Weird that I didn't see it before. Well if anyone else wants to play too, we can help each other.
If it helps anyone else, when I was stuck on 17, I got frustrated and started playing from lvl 1 on up, and got bored because of their simplicity, and went back to 17. Then after toying around with it a bit more, I got it to work. I think playing older levels helped me to see things that I didn't see before. Unconsciously, that is. I really wasn't sure what I was doing. It was weird. I got bored with what the method I was trying before, did something differently, and it worked. I don't even know how I did it, or if I could do it again. So weird...
these types of puzzles because they are so trivial tend to not be beneficial in increasing intelligence unless one can understand the math behind it. it's because 'trial and error' is what's usually used for the more complicated ones. this doesn't really teach you anything. if anything, it can make one stupid. even if one completes it, it is doubtful that anything is learned by most.
I'm doing the puzzles because I'm bored, and it's a fun way to waste my time. Please Register or Log in to view the hidden image! NOW HELP ME CONNECT THEM >.<
if you can't see the solution when you look at the cube. it's like trying different keys for a lock and not knowing which one works (guessing). one thing you can be assured of is that it's set up to have a perfect solution. just try different pathways. if you like tedious tasks, you will enjoy it.
