On PlayStation Network, there isn't exactly a shortage of puzzle games. If you log onto the PSN and count all of the games in the genre, you'll come up with over forty. And some of those games, like Shatter and Braid, are amongst PlayStation 3's best downloadable titles. But among the more traditional puzzle fare, there isn't a whole lot to choose from in terms of quality titles. And that's where we have both some good news and some bad news. The good news is that Super Stacker is actually a pretty fun game, with lots of depth. The bad news, unfortunately, is that Super Stacker isn't a top echelon title when compared to other premium titles on the PSN. But that doesn't detract from what it happens to do right... which is a lot.
