Tetris
Tetris on Game Boy is Nintendo’s monochrome handheld adaptation of Alexey Pajitnov’s falling-block puzzle. Nintendo released it in Japan on 1989-06-14, in North America on 1989-07-31, and in Europe on 1990-09-28. The cartridge provides A-Type endurance play, a 25-line B-Type challenge, and a two-player Link Cable battle requiring two systems and two cartridges. Its compact rules hide very specific machinery: a 10-by-18 playfield, one-piece preview, 21 gravity speeds, level-based line scoring, a peculiar hardware-driven randomizer, and no hold or hard drop. Bundling Tetris with the Game Boy outside Japan made this edition extraordinarily widespread; the official Tetris history reports more than 35 million copies sold. The original cartridge is officially playable today through Game Boy – Nintendo Classics for Nintendo Switch Online, including local-wireless and online two-player support.
