Im not sure what you mean by 'link'. Maybe you mean Sync?

If you are looking to Sync the two devices, you have to upload your data to icloud. Apple gives us all 5GB of free storage. I normally sync my Notes App, Contacts, Calendar, Reminders and a few other. You have to be using the same Apple ID on both devices.
Go to your Settings. Go to iCloud. turn on the apps you want to sync.

The game doesn't support Game Center.

To sync data between devices, the app has to support Game Center.

Contact the developer and request they add support for Game Center.

You most likely need to sync your iPad with iTunes on your computer, then sync your iPhone with iTunes on your computer. Then, all three items (iTunes on the computer, iPad, and iPhone) will be in sync. Everything is synced though iTunes, which is on your computer.

Your iPad and iPhone are shuttles that dock with the Mother Ship.

You can choose iTunes to sync iPad with your Mac, but you should be careful when you are using iTunes to sync iPad. iTunes is not simply backup or transfer software, and it doesn't allow you to transfer non-purchases. So you only have authority to sync purchased items, including apps, music, movies and so on to your Mac or iTunes library. Check out the following steps.

1. Authorize your new computer to use your Apple ID. Install iTunes on your new computer and then Authorize it in the Store tab.This is the email address you use to sign into iTunes (and probably anything else Apple-related). If you don't know it offhand, you can just check the computer you're currently syncing with. If you go into the iTunes Store it should appear in the upper-right corner. Once you know it, go to the new computer you want to sync with and locate the Store menu. From there, choose "Authorize This Computer". (In the event you've switched Apple IDs and made purchases with more than one, you'll need to perform this authorization for every account.)
2. Back Up Your iPhone. Just in case anything goes wrong when you are syncing, back up your iPhone, so that if all else fails, you'll be able to restore it to the way it is right now. To do this, connect your iPhone to your computer with its USB cable and open iTunes, Click "File > Device > Back up".
3. Transfer Purchases from your iPhone. Now you'll want to transfer all of your iTunes purchases (including free apps, paid apps, songs, books and movies) from your iPhone to your new computer. To do this, right-click (CTRL-click on a Mac) your iPhone within iTunes and choose Transfer Purchases. Or click "File > Devices > Transfer Purchases from my iPhone". Then iTunes will start syncing the purchased items to the library.
