There are several types of well-rendered 3D dice and tables to choose from. The actual "rolling" is done by shaking the iPhone, which is a good time. The app will eventually be raised in price, but right now it can be found for free on the App Store. Frankly, this kind of pricing change smacks of top apps list scamming to us, but we'll give Fullpower the benefit of the doubt, as they say it's a promotion.
However, we do have a bone to pick with Fullpower about this app. As fun as Yahtzee is (though there is one set of Poker dice, so you can play that, too), most of the dice that TUAW nerds -- or former TUAW nerds -- roll are of the d8, d10, and d20 variety. Any chance we can get a few of those added into the dice-rolling mix? d6s are all right for some damage types, but we can't roll a Nat 20 or break out the d4 Magic Missile with the program as it is.
