Thirty years ago today, Russian programmer Alexey Pajitnov released Tetris on the Elektronika 60. The puzzle title caused quite a stir and was ported to multiple formats, but it was the 1989 Game Boy edition which propelled it to international fame. Without it, the Game Boy would arguably have been less successful, and without the Game Boy, Tetris might never have reached the level of recognition it enjoys today.
Since launch, Tetris has sold over 170 million copies across all of the formats it has been released on, making it not only one of the most critically acclaimed video games of all time, but also one of the most commercially successful.
Are you old enough to remember the pre-Game Boy days of Tetris, or was the Nintendo version your introduction to the title? Perhaps you're a little younger, and have grown up with subsequent iterations of the game — such as the excellent DS sequel? Let us know by posting a comment below, and share some of your Tetris-based memories.
