Solved! My 10.1 Samsung is set on auto rotate, but the Word game will not.

Solution
If everything else on the tablet will auto rotate, but the game will not, then it is an issue with the game. You would have to check the game apps settings to see if something was changed, or if there isn't anything there, contact the apps creators about the issue.
