Well of course I've played Tetris. It's the ultimate casual game.

Sometimes I find myself going off to a flash Tetris site, and I keep record of my high score and see if I can beat them. Which I do every time.

I've played several different forms of tetris before. My favorite would have to be Tetris for the gameboy. For some reason that one to me has the catchiest music. I've also played the NES version, but it's not as good.

Of course I played it but I'm not a fan of the old versions, just new better looking recent remakes of it and I'm a huge fan of the music. I have a remix for the music from London orchestra.

Oh boy have I played Tetris. I haven't really played the game a lot, as I really don't like it, but I have played a ton of different versions of the game. I've played the original, Tetris Blitz, and more. I really am not very good at the game, so that is why I really don't play it all that much, but I bet if I was better at it I would like it more and maybe play it just a little bit more. 

I've got Tetris on my phone. It's basically he only thing I do on that anymore! xD The NES version is cool too, and I just can't get enough of that theme~!

I've played Tetris a lot. I got it when I got my first Game Boy (the original one) way back when, and used to play it all the time. Since then I've played it on the Nintendo 64, two different versions on the Xbox 360 and I have the mobile phone version. And, of course, I've played a couple different versions of it on Vizzed as well. I think it's one of those games that I just won't get sick of playing.

I have had exposure to several different versions, starting with the Game Boy version that came out in the late 1980s.  More recently I have been playing Tetris Axis on the 3DS, although not as much as I used to.  In between I have spent occasional time at the Tetris Friends website, played Tetris Party on the Wii, and once tried to play Tetris Worlds on PS2.  The last of these I never touched again because the evolving backgrounds actually caused me to freak out, not to mention they were very distracting.

Tetris is given credit for making casual gaming popular, so there are likely many more people who have at least heard of the game than I can possibly dream of.  For me, however, I prefer the old rule set that forced you to play every piece.  Not that the current rule set that allows you to hold a piece is bad; I just feel that particular aspects of the game as it stands now may be too complicated for its own good.  But that's just my take on it.

I have played it a few times. While I don't play it that frequently once I do I can get stuck for literally hours trying to beat my score, that's basically how I am about most arcade games that are addicting :/ It's a really good time killer to when I'm just waiting for something else or I'm bored and need to pass time somehow.

I played it heaps as a kid on the original Gameboy.

I have only played the game boy colour version of this game. Since then I haven't been able to try out others. Which I heard is great to play maybe one day I'll get too.

I have played Tetris as well as many other people have. I really think that most people have encountered Tetris in some form.

I had 2 copies:
1 on gameboy and the other was in a bundle with Star Wars The Clone Wars for xbox
