In this variant of the classic Tetris, the pieces have always the same shape, but the figures that compose them have their role. You can change the relative position of these figures during their fall, and your goal is to put together the equal figures. When you have joint 3 of them, they will disappear.
Arrow keys right/left to move horizontally. Arrow key up to rotate the figures integrating the falling piece; arrow key down to drop the piece.
