Tetris is receiving the Google treatment today in celebration of its 25 year anniversary. It is one of the (very) few titles that exists on nearly every console, in addition to calculators, portable media devices, smartphones–the list goes on.

It was developed by Russian programmer Alexey Pajitnov while he was working for Dorodnicyn Computing Centre and was created this date, June 6th, in 1984. The name “Tetris” derives from the greek numerical prefix “tetra-” and tennis, Pajitnov’s favorite sport. What’s more, Tetris‘ popularity took off during the Cold War, a time period when the United States and the then USSR’s relationship was not exactly on the best of terms, making it one of the only cultural trends to reach the US from the USSR.

Happy birthday, Tetris!
