As this article points out Alexey Pajitnov’s world-conquering puzzle game Tetris, programmed in the then-Soviet Union in 1984, is 25 years old (I’m unsure whether today is it’s exact birthday or whether it was finished at around roughly this time in ’84). Annoyingly, that article completely fails to mention that the first official appearance of Pajitnov’s game on these shores was its publication for a number of popular home computers by Mirrorsoft in the Spring of 1988, well before the Nintendo Gameboy version appeared in 1989 (there’s also mention of a 1985 PC version but I don’t think it was released in Europe). Tsk.
Anyway, happy birthday to Tetris. May you continue to cause people to go to sleep at night dreaming of falling bricks for many years to come!
