“ZTetris” is a great “Tetris” clone that tops all of the others that I have tested. The graphics are great; only having grayscale could be better. There are nine different levels of play that have there own unique graphical wallpapers. There are seven different “Tetris” shapes that can be rotated very easily with two different keys. Two functions set this “Tetris” clone apart from all the others: first there is a link play that allows two players to verse each other. The other is a save function so that you can keep up your “ZTetris” game running at different times.
