What if I don't want to play her games?

This girl I work with, I've liked for awhile. Recently she started talking to me more than normal. Stuff like we should go to the movies, we should hang out sometime, stuff like that. The past 2 weeks, however, every time I ask her if she wants to hang out, she has an excuse not to. I know she is just playing games, I've even heard it from other people, but I don't want to play games, I just want to tell her how I feel. How do I do that if I can't seem to get some one on one time with her? She said that she really does want to hang out, it's just been bad timing so I don't know what to make of that, if it's sincere or what.
