A wonderful game for its time. It keep up late many a nights.
The game has geometric shapes that fall down a column and the idea is to turn them and move them as they fall so they fit in the other blocks at the bottom without any gaps. It is a very simple concept and not so easy to conquer. The later games that built on the concept got to glitzy for me. I liked the original game the best.
Everybody should play Tetris at least once in their lives. It is a great game for brain. There isn't any shooting and killing in Tetris. I am not saying I don't like shooting and killing. My favorite genre is shooting and killing games.
