This is HD version. Recomanded high-resolution devace (min 480x320) Is a game with many similarities to Columns. The game takes place inside a tall, rectangular playing area, as in Tetris. Columns of three different blocks appear, one at a time, at the top of the well and fall to the bottom, landing either on the floor or on top of previously-fallen "Columns". If, after a column has fallen, there are three or more of the same blocks connected in a straight line horizontally or vertically, those blocks disappear.
