Not sure where else to ask so I'll ask here. Facebook Q?

So I've got an iPad and an iPhone. Before I knew that I could play the same game on two devices, I started a game on my iPad and a game on my iPhone. Now, I want to get rid of the one I play on my iPhone and instead use my iPad's account on there. My iPad's account is connected to my Facebook. I tried deleting the app from my phone and reinstalling, but it was still picking up my game from that account. Is there any way to just blast the information for that game out of there and log in with my Facebook on that iPhone?
