IPad Question about Candy Crush
 

I just got a new iPad yesterday. I had an iPad3 and updated to the iPad Pro. It looks like everything transferred but Candy Crush. It's there and says its full but I can't open it. I don't think I had a user name and I was on level 500. Any ideas on how I can restore Candy Crush to level 500? I'm going to give my old iPad to a friend but I haven't deleted my information yet! Thanks in advance.
