Yes - your iCloud backup, if used to set up the new device, will restore your game data to the device that is using that backup. When you do the backup of your older iPad in preparation for setting up the new one, be sure to go to Settings>iCloud>Storage>Manage Storage, click on your iPad (if you have multiple devices backing up to iCloud), then check to make sure the games you want included in the backup are turned on. Click on Show All Apps at the bottom of the list if you don't see the game or games in question.
When setting up the new iPad, restore it from the backup you made above.
Cheers,
GB
