Its amazing what legs the Tetris concept has. Every year some new variation on the genre impresses me, and this is this years. Very simple to grasp, but looks to have a lot of strategy. With only four columns and no rotating, it ends fast enough that it can be turn-based and require no reflexes, which is nice. Ignore those asking for block rotation... Theyre going by convention but dont understand the game. Rotation would make it too easy and pointless.
