Can I play on my iPad? The app is listed for iPhone...

Yes, of course. This app is a valid iOS application and does work on the iPad. Even though it is listed in the Apple App Store as an iPhone app, it also works on all versions of the iPad!

We support all iOS devices running the latest version of iOS. That includes iPads used in 'compatibility mode.' 

Download the app and then try a practice game before the real Challenge begins!
