OMR is giving solid advice.
Way back when I was a single guy, I never tried to have "game". I was merely brutally honest. If I saw a girl that was deserving of a compliment, I gave it to her. I was once talking to a very pretty girl at restaurant. We just happened to be sitting a couple of seats away from each other. I was not eavesdropping, but I overheard her having an intelligent conversation about her last boyfriend with her girlfriends. It was clear that he had lead this girl on for a few years, with no intention on taking it to the next level.
When there was a break in the conversation, we began talking. I found out she had a very good job, was educated, and she was a 9 on the GetBig scale. I had no intention of hooking up with this girl, but I said to her: "Whomever you were talking about is going to regret his decision in the future. You are stunning, smart and more importantly, very funny. Unless you are a total nag when you are in a relationship, it was his loss."
Turns out, she was worse than a nag, but the honesty helped me find that out.
