Not very challenging.

The difficult level isnt so much more difficult... Its just your opponent gets better rolls. And once you start to win... Your opponent starts getting better rolls! Every. Time. It is pretty annoying. Im giving the game 4 stars because it is a great way to teach my kids how to play. And it will pass the time, but it isnt very challenging. I wish the game would play smarter instead of just getting 4 doubles in a row.
