Tetris is a game which needs no introduction. Since the original version in 1986, dozens of clones have appeared on every conceivable platform, from the lowly Commodore 64 to powerful X Window terminals, making Tetris one of the most popular pastimes in video game history and at the same time the most popular game for hobbyists to clone. By 1992 it seemed that everyone and their dog had written a version, or knew someone who had written one.
The first commercial version of Tetris in the United States by Mirrorsoft / Spectrum Holobyte in 1987 has attained great popularity, but it is in many ways inferior to the arcade version offered by Atari Games Corporation in 1988. The Atari version improved upon other versions by adding better graphics, better animation, a stronger scoring mechanism, and, most importantly, discrete levels.
This clone is based on the Atari version. While it lacks the animated dancers and a musical score, the animation is smooth and the shaded 3D game pieces drop in real-time. If you have played the Atari version, you should feel comfortable with this one.
