Hello, I was trying to get gold stars in all my completed single player levels but I really can not find a way to get it in the tutorial... There once was the tutorial breaker achievement that I got, now I do not absolutely know how it works. Someone suggested me that it is not a matter of strategy but just a little imperfection in the stats reports, I was wondering if it is possible to change it.

Maybe we should have been clearer in https://www.warzone.com/Forum/422731, but there is a reason you can't get a gold star for the tutorial. The tutorial doesn't have any enemies in it, and guides you trough the basic gameplay. This results in everyone finishing the tutorial on the same turn, and thus a star is pointless.

Whoa no

Some people complete it in 7 and some people complete it in 6

Just do it like me.
Create a new account and don't play tutorial on it.

I was really thinking of, if only I could transfer the stats of almost 2200 games in multiplayer lol
