Free Tetris online

I don't know if my readers are as old as I am and remember playing the grate game of tetris on Nintendo. I started really wanting to play that game but no longer have my old NES to play it on. I also don't feel like buying one when my son is getting a game cute for Christmas. I tried looking for one for the game cube but just couldn't find one. So I checked to see if there was a PC version. Sure enough there is! And it is totally free too. So now I will probably make less money because I am going to be online playing the most addictive game in the world:) Hey at least its good clean and free fun right? http://www.online-game.tv/play/tetris
