I was in closed beta for this game, and at the time it was said that it would work on iPhone. They may have abandoned this, but if it worked for iPhone it should work for iPad. There is no scroll bar.
That being said, I believe it is a shameful milking of the Ultima name and nothing more. I really wanted to like it and for the Ultima brand to be revived, and I'm confident it will be. Just not here.
