Year: 1989 (1986 NES)
System: Game Boy

With countless iterations across every platform known to man, Tetris is arguably the alpha and omega of all puzzle games. It’s the first puzzle game that comes to mind when the genre is suggested, and arguably we’ve all probably had more fun with it than any other game in the genre; this game was so hot back in the 80s it essentially incited a corporate war between Nintendo and various competitors for publishing rights. (The Game Boy version, while identical in gameplay to its console counterpart, holds particularly fond memories because the music was far superior to the NES version.) Just about every puzzle game out there has either been directly inspired by or owes something to Alexei Pajitnov’s original design, period. That alone is proof positive that it’s still the original and the best.
