Fun but freezes

I really enjoy Sudoku and this has been fun but it constantly freezes up on me. If this doesnt get fixed, Im gonna be deleting the app because Im not enjoying having to close the game all the time.

Maybe the freezing was because I wasnt really using wifi for it but their crossword game doesnt freeze when Im not on wifi. Who knows.
