Cant get iCloud to Work!

I enjoyed the game which I downloaded to my iPad. Ive played it for hours and now I want to transfer to my iPhone6+ for taking it with me. However, the iCloud game I saved on my iPad doesnt appear on the iPhone iCloud save menu in-game. I dont know what to do! The app is checked as far as being apart of my iCloud backup for both devices (and Ive obviously backed both of them up). What do I do?
