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. The character also appears in more than 30 officially licensed game spin-offs, as well as in numerous unauthorized clones and bootlegs. According to the Davie-Brown Index, Pac-Man has the highest brand awareness of any video game character among American consumers, recognized by 94 percent of them. Pac-Man is one of the longest running video game franchises from the golden age of video arcade games, and one of only three video games that are on display at the Smithsonian in Washington D.C., (along with Pong and Dragon's Lair).
Gameplay
The player controls Pac-Man 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 amount of time the enemies remain vulnerable varies from one stage to the next, but the time period generally becomes shorter as the game progresses. In later stages, the enemies do not change colors at all, but still reverse direction when a power pellet is eaten.
In addition to dots and power pellets, bonus items, usually in the form of fruit appear near the center of the maze. These items score extra bonus points when eaten. The items change and bonus values increase throughout the game.
Enemies

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. The behaviors of each enemy have been exactly determined by reverse-engineering the game.
Development
The North American Pac-Man cabinet design differs significantly from the Japanese Puck Man design.
The game was developed primarily by a young Namco employee named Tōru Iwatani over the course of a year, beginning in April 1979, employing a nine-man team. It was based on the concept of eating, and the original Japanese title was Pakkuman (パックマン?), inspired by the Japanese folk hero "Paku" who was known for his appetite[disputed – discuss] as well as by the Japanese onomatopoeic slang phrase paku-paku taberu (パクパク食べる?), where paku-paku describes (the sound of) the mouth movement when widely opened and then closed in succession.
Although Iwatani has repeatedly stated that the character's shape was inspired by a pizza missing a slice, he admitted in a 1986 interview that this was a half-truth and the character design also came from simplifying and rounding out the Japanese character for mouth, kuchi (口). Iwatani attempted to appeal to a wider audience—beyond the typical demographics of young boys and teenagers. This led him to add elements of a maze, as well as cute ghost enemy characters. The result was a game he named Puck Man.
Later that year, the game was picked up for manufacture in the United States by Bally division Midway. For the North American market, the name was changed from Puck Man to Pac-Man, as it was thought that vandals would be likely to change the P in "puck" to an F, forming a common expletive. The cabinet artwork was also changed.
