The only thing more remarkable than the longevity of Tetris -- the Mother of all Puzzle Games -- is the number of iterations of Tetris. The latest, Tetris Evolution, does little to change the basic premise of geometrically shaped blocks (two dimensional tetrominoes comprised of 4 pixel-like squares) falling downward. You rotate and route them along the way to have them land at the bottom in the hopes of creating at least one contiguous line that will then disappear, making room for the unrelenting stream of new blocks coming down.

Still addictive as all heck in this Xbox 360 version, but no more so than the various cheapie and freebie versions littering game store bargain bins and casual game web sites around the world. Except the visuals are expectedly striking and there are a whole eight different modes, all involving the basic block, drop and vanish shtick. Even the online multiplayer mode does little to change the fundamentals of the game save for the ability to dump pieces on an opponent. It's no big thing.

While everyone and their collective dog should certainly own at least one version of Tetris, Tetris Evolution is not it. It's simply too expensive, even at "value pricing," should have been made as an Xbox Live Arcade purchase option for $5, and doesn't really offer anything better than the innumerable cheap or free versions (and knock-offs) of Tetris already permeating the planet.
