Pac Xon is an arcade game developed by Namco and licensed for distribution in the United States by
Midway, first released in Japan on May 22, 1980. Immensely popular from its original release to the
present day, Pac-Man is considered one of the classics of the medium, virtually synonymous with video
games, and an icon of 1980s popular culture. Upon its release, the game—and, subsequently, Pac-Man
derivatives—became a social phenomenon that sold a bevy of merchandise and also inspired, among
other things, an animated television series and a top-ten hit single. When Pac-Man was released, the
most popular arcade video games were space shooters, in particular Space Invaders and Asteroids. The
most visible minority were sports games that were mostly derivative of Pong. Pac-Man succeeded by
creating a new genre and appealing to both genders. Pac-Man is often credited with being a landmark in
video game history, and is among the most famous arcade games of all time. It is also the highest-
grossing video game of all time, having generated more than $2.5 billion in quarters by the 1990s.

The player controls Pac Xon through a maze, eating pac-dots. When all dots are eaten, Pac-Man is taken
to the next stage, between some stages one of three intermission animations plays. Four enemies
(Blinky, Pinky, Inky and Clyde) roam the maze, trying to catch Pac-Man. If an enemy touches Pac-Man, a
life is lost. When all lives have been lost, the game ends. Pac-Man is awarded a single bonus life at
10,000 points by default—DIP switches inside the machine can change the required points or disable the
bonus life altogether. Near the corners of the maze are four larger, flashing dots known as power pellets
that provide Pac-Man with the temporary ability to eat the enemies. The enemies turn deep blue, reverse
direction and usually move more slowly. When an enemy is eaten, its eyes remain and return to the
center box where it is regenerated in its normal color. Blue enemies flash white before they become
dangerous again and the length of time for which the enemies remain vulnerable varies from one stage to
the next, generally becoming shorter as the game progresses. In later stages, the enemies go straight to
flashing, bypassing blue, although they still reverse direction when a power pellet is eaten.

The enemies in Pac-Man are known variously as "ghosts" and "monsters". Despite the seemingly random
nature of the enemies, their movements are strictly deterministic, which players have used to their
advantage. In an interview, creator Toru Iwatani stated that he had designed each enemy with its own
distinct personality in order to keep the game from becoming impossibly difficult or boring to play. More
recently, Iwatani described the enemy behaviors in more detail at the 2011 Game Developers
Conference. He stated that the red enemy chases Pac-Man, and the pink and blue enemies try to position
themselves in front of Pac-Man's mouth. While he claimed that the orange enemy's behavior is random, a
careful analysis of the game's code reveals that it actually chases Pac-Man most of the time, but also
moves toward the lower-left corner of the maze when Pac Xon is facing a certain direction.
