Tetris the game which involved rotating falling blocks (tetrominoes) so that they would land to fit perfectly into the blocks below is celebrating its 25th anniversary today! Have to admit this is a benchmark to all gaming especially the puzzle genre. Notably remember this beauty of the Nintendo line up of gameboy hand held consoles.

Having sold more then 70 million copies and been sold on a multitude of platforms the game was first made available on the IBM computer, but it didn't become a major hit until it was launched on Nintendo's Game Boy hand held console in 1989. It has been reported that the Game Boy version of Tetris sold more than 35 million copies!

Happy 25th Anniversary!
