It works quite well! It starts an add on lunch which you can skip after a few seconds. The app itself is great and works perfectly! I love the options for different layouts and the sound effects are spot on. I noticed that some people have complained about this app. First it is not a game but a calculator. Secondly if you don't like the gravity control you can turn it off in the options.
The screen when black when i open the app...it does not work
I love this app it is tottally amazing
