Well without root there are only 2 options I know of that you can use (android sucks that way). Most apps just backup other stuff like pictures or sms or apk etc but if you wanna backup a game's data then you'll either have to use the Helium Backup and Sync app or make an adb backup. I will not recommend adb since it basically backups your entire phone so taking frequent backups is not possible and the backup size is pretty huge too-also its buggy.

So for Helium, you'll also need a PC or Laptop. Download the Helium app on your phone. Then search for and download the Helium Desktop app on your computer. Connect your device to your PC with a USB and launch Helium app on both. They will sync and after that you will get the option to select an app and make its backup. The sync process is a one time thing but you'll have to connect to a PC everytime you wanna backup. You can just Google for this app and you'll get detailed step-by-step instructions on how to use it on plenty of websites :)
