Ive tried a lot of dice games, and this one is the best Ive found. They get the little things right. The roll button is in the bottom right-hand corner (can be flipped left in settings) where its most comfortably accessed. The scoring area is clearly organized and readable if you switch to a solid, dark background. (their textured Christmas default theme is horrible) and their statistics include an average score, so you can see progress or regression over the long term. They offer online games against other people, but they dont force you to play that way. You can play on your own, which I appreciate.
