Ultris: The Ultimate Tetris

Ultris is a more impressive package than it first appears. Described by the then-14-year-old author as "The Ultimate Tetris" it in fact includes both Tetris and Columns clones. These games work well enough, and include standard features like "next block". One of the big draws is that you can play two player mode, with one player using the keyboard and the other using a mouse. You can play independently of each other or you can play co-op or competitive modes. The graphics are fine for a puzzle game and the numerous options and variety provided make this Tetris clone stand out from many of the others.
