Compie 30 anni in questi giorni e rimane tra i videogiochi più venduti di tutti i tempi: il Tetris è stato inventato dall'ingegnere russo Alexey Pajitnov il 6 giugno 1984.
Sono bastate due settimane a Pajitnov per mettere a punto il codice del gioco, i cui diritti sono stati donati all'Unione Sovietica, che all'epoca non prevedeva la proprietà privata.
Dall'URSS è poi stato portato in Ungheria, e da lì è arrivato nel mondo occidentale, divenendo famoso soprattutto dopo che nel 1989 la Nintendo ne realizzò una versione per il Game Boy appena uscito.
