Tetris does not require a classic controller. It’s one of the most-ported games ever, playable on virtually any input device:
Top players (CTWC, Tetris 99, Jstris) overwhelmingly prefer **keyboard** (roll/ hypertapping) or **high-quality D-pad** (8BitDo M30, Saturn, Fighting Commander) for speed and accuracy. Analog sticks introduce dead-zone drift.
Choose whatever feels comfortable. The blocks don’t care.
