Tetris

Tetris is Alexey Pajitnov’s falling-block puzzle series, licensed worldwide through The Tetris Company across arcade, home, and handheld platforms. Landmark Nintendo versions on Game Boy and NES helped define the brand, while later official releases span Spectrum HoloByte and Blue Planet Software ports, Arika’s Grand Master line, Ubisoft and Sega collaborations, Enhance’s Tetris Effect, and archival compilations such as Digital Eclipse’s Tetris Forever.
