A while back I meet this chick during my creative writing class, we really didn't talk till about the middle of the semester. We began to talk about psychology and I began to use the Cube Game routine which completely wowed her (She started telling me things about her personal life and how I was correct on the statement.) After class I ask for her number which was successful but whenever I text her from time to time she either answers really late or sometimes days later yet she always hugs me after I leave and we always have meaningful conversations whenever we talked. I always embraced the cocky funny style which seemed to work for her, whenever I said we should hangout sometime she usually said for sure or definitely. So what do you guys think. is she possibly interested or is she simply being friendly?

Note: She introduced me to some of her friends, this one dude I knew because I worked out at the gym with him and she hugged him too yet I never saw her hug anyone else besides me or him.

She is at least being friendly. The question is whether there is something more. If you are unsure there probably isn't, because you are playing it "safe", which rarely takes it anywhere and is actually less safe than a more "risky" approach. You need to be clear in your intent and more bold, more aggressive. More specifically, this means you need to give her IOIs. The smarter she is the more subtle the IOIs (and vice versa, if she is not that smart you need to be very obvious). If you make the mistake and overdo it, just back off for a while and play it cool.

Much appreciated on the advice my friend. I did look for IOIS like you said specifically she always laughed whenever I said something funny or smiled a lot near me. I always played the subtle approach yet it yields mixed results, gotta step it up a little.
