Constant freezing. Wont respond to touch.

I really hate to leave a negative review. My husband and I enjoy this game very much. We play it on his iPad regularly. It works perfectly on his. But, for some reason on my iPad and my phone this game keeps freezing up. It will let me put in a few numbers and then it won’t respond to touch anymore. It’s very frustrating. I wish there was some fix for this. But there’s no means of communicating with the makers of this game that I know of.

I love sudoku , when you put a number in the wrong place, the number turns red so you know it , so you can just put a number on whatever place and you just do it until you get it right, I have been using this as an average, it also has a mark which is a pencil and two pluses , if you press it, it shows you the choices of each square so you can just put the numbers it shows and finish another game, it also has different levels to suit you , its really fun so five stars.

Maybe, I missed something; but, I never see my score. This is a new app for me.
