Keeps freezing

I started playing with this app to kill time. I got sad when I noticed that every time I click the question and exclamation mark the game freezes and I have to close out of it. Also, when I try adding another element from my list it freezes. Although i would like to find all the different combinations, I think the freezing is going to make me uninstall before I actually do. I like the app aside from those issues.
