Part 4/10:
Utilizing an outdated Electronica 60 computer, Pajitnov adapted the traditional Pentomino game for the digital world. His first attempt was dubbed "Genetic Engineering," but it fell flat due to its lack of replayability. Determined to enhance its appeal, he introduced fast-paced gameplay where the puzzle pieces fell continually, keeping players engaged by rewarding them for completing rows—an addictive format that birthed Tetris. He named the game by merging "tetra," the Greek word for four, with his love for tennis.
