Play Tetris Online

Summary

Tetris, often just called Sega Tetris when referring to Sega’s 1988 arcade release, sticks to the timeless formula of stacking falling tetrominoes to erase horizontal lines. The pieces drop from the top‑center of a rectangular field, and you can slide them sideways, rotate them, and even hard‑drop them for an instant placement. Each cleared line speeds up the descent, and a four‑line clear – the classic “Tetris” – rewards the biggest point boost. Early Sega hardware used a completely random piece distribution, a contrast to the modern “bag” system that guarantees each of the seven shapes appears once per cycle. The iconic “Korobeiniki” melody, now synonymous with the franchise, was already part of Sega’s version, cementing the tune as the series’ unofficial anthem. Even without today’s hold‑piece mechanic, the core challenge of preventing the stack from topping out remains as addictive as ever.
