PuckMan (Japan set 1) 1980 Namco Puckman © 05/1980 Namco. - TRIVIA: This game is known outside Japan as Pac-Man. A Bootleg of this game is called Ghost Muncher. Some hacks are known as New Puck X, and Joyman. Puckman was conceived at lunchtime... literally. The designer was very hungry, and ordered a whole pizza for himself. He took one slice, and Puckman was born. The game took 1 1/2 years to complete, and had five people on its team. Puckman is the greatest selling arcade game of all time, and is arguably the most well-known video character. It had its own cartoon, lunch box, board game, and hundreds of other products. Puckman was also the first game to have a "character", and changed the face of video games forever. Puckman was the first video game to be as equally popular to women as it was with men. After the 255th level, Pac-Man locks up. This lockup does not occur if, at the end of level 254, the number "255" appears at any point within your score. - SERIES: 1. Puckman 2. Ms. Pac-Man 3.
