TeTriS DS..... COOL
This Tetris for the DS features some very fun game modes that will keep you busy and busy for hours. Whether your on the bus killing some time, or at home Tetris is sure to entertain you for as long as you need it to.
Playing with friends is one of the best things about this game in my opinion, its a great way to improve especially if your friends are better than you, and its just plain fun and a good laugh.
Online play is really good as well but its hard to have fun on it because almost every one you face seems to be a master at Tetris . So for the beginners I recommend you stay away from playing online at first, maybe a face a friend who is very good and then go online once you can get close to matching there play.
I recommend Tetris to all of you who Own a DS out there, some places have it used to so you can get it pretty cheep.
