Is it possible to save iphone games save on backup?

Hey i'm going to send my iphone to apple,
I would like to know if I can backup my games data so when my iphone comes back i can continue the games from where i left

Yeah you can, however it has to be backed to to iCloud not iTunes, first you need to go to setting and select iCloud then on the bottom there's a section that says "documents and data" make sure it's turned on. Go to storage and back up then to manage storage, select your phone and it should give you a list of all your apps any games make SURE the ones you want to save are all turned on once they are go back to storage and back up turn on iCloud back up and click back up now. That should save all your settings and all the apps you have on your phone plus the data saves for games.
