The rules of Tetris game are simple and well known. They require players to move and rotate pieces of different shape in such a way so as to complete one or more horizontal lines. Once the line is completed it will disappear.The purpose of the game is not allowing the pieces to over-fill the board. But we have changed the aim in our variant of the popular game. You should not only escape the over-filling of the board but also “sort out” the figures which are on the board. If the figure disappears you will pass to the next level where another figure is preparing for you.
