Tetris, one of the most iconic games of all time, has just turned 25.

The game was created by Alexey Pajitnov in 1985, while working for the Soviet Academy of Science. Pajitnov apparently got a bit bored working on his Elektronika 60 computer, and the rest is history.

Pajitnov named his brainchild tetris, combining "tetra", and the name of his favorite sport, tennis. The game went big after being launched for Nintendo Game Boy, and sold over 35 million copies.

Unfortunately, Pajitnov didn't get much in the way of cash, as the royalties were claimed by Soviet authorities. After he emigrated to the US in 1996, he eventually regained his rights.

The game has sold over 70 million copies so far, for a vast number of platforms, ranging from ancient workstations to mobile phones and PMPs.
