Tetris is one year older than Greg: Bomb.

I'll just put this on you. I love Tetris. I play a lot. I have different versions of it on my phone, iPod, computer, I played it on a Gameboy brick, on my Nintendo, and I've had a few Tetris dreams. So to say that I'm happy for Tetris on it's 25th birthday, would be an understatement. True story, i thought i could win a Tetris championship, until I played a true master.
