Mobile game tutorial, saved on local data or server?

Question

I can't quite figure out what is the best approach to tutorials on mobile games. Should the tutorial progress and its features (or some of it) be stored locally on the device or should it all come from the server?

(if someone has a guest account and a facebook account he may face the tutorial twice should it all be stored on the server, mind you)

Thanks in advance

I have a mixture of the two but it gets in the way when I revisit it

Answer 1

The tutorial progression status is the part of the user progress. If you have any information about the user progress store tutorial status there. The bigger problem though is user identification. Is this user someone who have played the game before or a newcomer? Is this registered user who we think it is or is it a different person? There is no other (feasible) way to confidently answer these questions, you can either make a guess based off the user behavior, or simply ask the user if he have played through the tutorial before. Or more correct if he wants to play it.
