Tetris

Tetris remains the purest expression of game design ever conceived, with over 520 million paid downloads across mobile platforms alone. Alexey Pajitnov's 1985 puzzle game achieves infinite replayability through elegantly simple rules, making it a universal cultural artifact. It consistently outperforms #10 Baldur's Gate 3 in terms of sheer global reach, being played by billions more people. Its 30% faster drop speed at higher levels creates a tension unmatched by any puzzle game since.
