A pretty cool game where you can play Tetris with other people. I found it incredibly addictive. The bad part is, the matches are all random people. Although, there is a beta which you could sign up for, where you can make your own rooms and tell your friends to come and play with you. You have to have an account though. There is a ranking system (Sort of like a level system), where you get points as you win games or lose points when you lose games. The more points you get, you can go up one rank and face other players with the same rank. Every time you get a line, it sends blocks to another player in the room depending on what kind of combos you did. There is no download required!
When you play the normal games ( Not Live ) Everyone sucks. So don't think that you're really good at the game from that. Try playing Live, people are much harder. There is a great skill distance between normal games and Live.
