"Pac-Man" is available for play online through FreePacMan.org and WebPacMan.com, as of May 2015. A variation of the game, "Pac Man Advanced," is available through KnowledgeAdventure.com.
FreePacMan.org and WebPacMan.com both provide the original version of the game. Each site also offers links to play other free versions of classic arcade games such as "Galaga," "Frogger," "Space Invaders" and "Asteroids." "Pac Man Advanced" is the same type of game, but with a different format for the mazes and ghosts.
"Pac-Man" was released on May 22, 1980, and it became one of the first popular arcade games that didn't involve space or sports. Toru Iwatani and his nine-man team developed the game for Namco. Titled "Puck-Man" in Japan, the company changed the name to "Pac-Man" in the United States to avoid vandalism of the machines.
In the game, a player controls Pac-Man and maneuvers him through a maze that contains pellets. Pac-Man automatically eats pellets as he moves over them, and the maze is complete when he eats all the pellets. Each maze also has four ghosts that chase Pac-Man. If one or more of the ghosts touches Pac-Man, he dies.
The popularity of "Pac-Man" led to numerous sequels and spinoffs, including "Ms. Pac-Man," "Pac-Man World" and "Pac-Man: Adventures in Time."
