I'm not familiar with the game. What you should look for is whether it has Game Center support, or perhaps FaceBook. If it does, make sure you sign in with the same account on both devices. In Game Center's case you'll need to be signed in under Game Center, and turn on the feature in the game itself. In FaceBook's case, you sign in with your account in the game.
Not all games offer Game Center support, and even the ones that do may not offer all the supported features, so even if these are available there is no guarantee it will retroactively sync the games. But it might.
