Does not work on my iPad

I have a iPad with plenty of space. After download I was never able to get passed the door ( with Mr. Carson ) and it either took me to the Facebook log on page ( dont have Facebook on pad) or crashed. My husband put it on his phone ( not Apple ) and none of the above happened and it seemed to play fine . I a my Leary of any game that insists you log on to Facebook? WHY?
