Pac-Man[a] is a maze arcade game developed and released by Namco in 1980. The original Japanese title of Puck Man was changed to Pac-Man for international releases as a preventative measure against defacement of the arcade machines. Outside Japan, the game was published by Midway Games as part of its licensing agreement with Namco America. The player controls Pac-Man, who must eat all the dots inside an enclosed maze while avoiding four colored ghosts. Eating large flashing dots called energizers causes the ghosts to turn blue, allowing Pac-Man to eat them for bonus points. It is the first game to run on the Namco Pac-Man arcade board.

The development of the game began in April 1979, directed by Toru Iwatani with a nine-man team. Iwatani wanted to create a game that could appeal to women as well as men, as most video games at the time were war- or sports-themed. Although the inspiration for the Pac-Man character was, reportedly, the image of a pizza with a slice removed, Iwatani has said he also rounded out the Japanese symbol "kuchi", meaning "mouth". The in-game characters were made to be cute and colorful to appeal to younger players. The original Japanese title of Puckman was derived from the titular character's hockey-puck shape.
Pac-Man is a widespread critical and commercial success. The game is important and influential, and it is commonly listed as one of the greatest video games of all time. The success of the game led to several sequels, merchandise, and two television series, as well as a hit single by Buckner and Garcia. The Pac-Man video game franchise remains one of the highest-grossing and best-selling game series of all time, generating more than $14 billion in revenue (as of 2016[update]) and $43 million in sales combined. The character of Pac-Man is the mascot and flagship icon of Bandai Namco Entertainment and has the highest brand awareness of any video game character in North America.
The player navigates Pac-Man through a maze with no dead ends. The maze is filled with Pac-Dots, and includes four roving multi-colored ghosts: Blinky, Pinky, Inky, and Clyde. There is a passageway from the left side of the screen to the right side, one energizer in each of the four quadrants, and bonus fruits that appear in each level.
The objective of the game is to accumulate as many points as possible by eating dots, fruits, and blue ghosts. When all of the dots in a stage are eaten, that stage is completed, and the player will advance to the next. Between some stages, one of three intermission animations plays. The four ghosts roam the maze and chase Pac-Man. If any of the ghosts touches Pac-Man, a life is lost. When all lives have been lost, the game is over. The player begins with three lives, but DIP switches in the machine can change the number of starting lives to one, two, or five. The player will receive one extra life bonus after obtaining 10,000 points. The number of points needed for a bonus life can be changed to 15,000 or 20,000 or disabled altogether.
Near the corners of the maze are four flashing energizers that allow Pac-Man to eat the ghosts and earn bonus points. The enemies turn deep blue, reverse direction and move away from Pac-Man, and usually move more slowly. When an enemy is eaten, its eyes return to the center ghost box where the ghost is regenerated in its normal color. The bonus score earned for eating a blue ghost increases exponentially for each consecutive ghost eaten while a single energizer is active: a score of 200 points is scored for eating one ghost, 400 for eating a second ghost, 800 for a third, and 1600 for the fourth. This cycle restarts from 200 points when Pac-Man eats the next energizer. Blue enemies flash white to signal that they are about to return to their normal color and become dangerous again; the length of time the enemies remain vulnerable varies from one stage to the next, generally becoming shorter as the game progresses. In later stages, the enemies begin flashing immediately after an energizer is consumed, without a solid-blue phase; starting at stage nineteen, the ghosts do not become edible at all, but still reverse direction.
There are fruits that appear twice per level, directly below the center ghost box; eating one gives 100 to 5,000 points. This table lists each stage, the type and value of the fruit that appears, how long the ghosts are blue when a energizer is eaten, and how many times the ghosts flash before returning to normal:
|Stage||Fruit||Fruit points||Ghost Blue Time (seconds)||Flashes before Blue Time ends|
|19 and beyond||Key||5000||0||–|
The enemies in Pac-Man are known alternately as "monsters" or "ghosts". Creator Toru Iwatani designed each enemy with its own distinct personality to keep the game from becoming impossibly difficult or boring to play. Iwatani described the enemy behaviors in more detail at the 2011 Game Developers Conference: the red enemy simply chases Pac-Man, the pink enemy aims for a position in front of Pac-Man's mouth, and the blue enemy "seek[s] to position itself at a similar fixed spot [as the pink enemy]". In practice, however, the blue enemy can behave like any of the other three enemies. Although Iwatani claimed that the orange enemy's behavior is random, it alternates between behaving like the red enemy when at some distance from Pac-Man and moving towards the lower-left corner of the maze whenever it gets too close to him.

Pac-Man was not designed to have an ending. However, at level 256, a bug corrupts the entire right half of the maze with seemingly random symbols and tiles, overwriting the values of edible dots, which makes it impossible to eat enough dots to complete the level. Serving as effectively the final level, it is known as "the split screen".
The bug is caused by the calculation of the number of fruit to draw rolling over to zero. The code attempts to draw 256 fruit (236 more than it was designed for), resulting in the maze being corrupted. The tilemap that holds the fruits is 20 elements long and is arranged into three cases. Case A handles levels less than seven. Case B handles levels 8–19 and Case C handles level 19 and above. When the game reaches level 256, the level counter overflows back to 0 and thus, level 256 is treated as level 0. The game executes Case A rather than Case C because the level number is less than seven. The algorithm that draws the fruits continues to draw fruit till the fruit number and the level number match. Upon reaching fruit number 255, the fruit number overflows back to 0 (matching the level number) and 256 "fruit" have been drawn. The game draws the first 13 fruit with no issues, but upon reaching fruit number 14, it begins to draw fruit on the right side of the map. Once the game reaches the 20th entry in the fruit table, the game can no longer draw any more fruit, but there are still 236 fruit it needs to draw and, thus, the game begins to draw pieces of the tile map onto the screen to substitute the 236 extra fruit. Pac-Man can move through most of the pieces, but some of them act like walls. Once all 256 fruit are drawn, the game draws 7 extra blank spaces after the final fruit.[clarification needed] The level is impossible to beat using only one game, as the player needs to eat 244 dots to move to the next level. Most of the dots have been overwritten by the tilemap. There are nine dots hidden within the glitch screen that re-spawn when the player dies, but with a maximum of five extra lives, this limits the number of dots to 168; however, if a player is able to "continue", the re-spawned dots can be eaten until the level is beaten. If level "0" is beaten, the player is returned to level 1, with the ghosts' difficulty set to very high (thus no Ghost Blue Time). There are also two broken keys at the bottom of the screen, one under the live counter and one under the level counter, which disappear if the round is beaten.
High score records and perfect playEdit
A perfect Pac-Man game is when the player achieves the maximum possible score on the first 255 levels by eating every possible dot, energizer, fruit, and enemy, without losing a single life, and using all extra lives to score as many points as possible on level 256.
The first person credited with achieving this score (3,333,360 points) was Esports player Billy Mitchell, who claimed to perform the feat in about six hours in 1999. However, in April 2018, video game ranker Twin Galaxies removed all of Mitchell's scores from its database after ruling certain Donkey Kong submissions were not achieved using original arcade hardware. Since Mitchell's Pac-Man achievement, as of 2019[update], 7 other players have attained the maximum score on an original arcade unit. The world record, according to Twin Galaxies, is currently held by David Race, with the fastest completion time of 3 hours, 28 minutes, and 49 seconds for the maximum possible score of 3,333,360 points.
Historically, in December 1982, an eight-year-old boy, Jeffrey R. Yee, received a letter from U.S. President Ronald Reagan congratulating him on a worldwide record of 6,131,940 points, a score only possible if he had passed level 256. In September 1983, Walter Day, chief scorekeeper at Twin Galaxies, took the US National Video Game Team on a tour of the East Coast to visit video game players who said they could get through level 256. No video game player could demonstrate this ability. In 1999, Billy Mitchell had offered $100,000 to anyone who could complete level 256 before January 1, 2000; the prize expired unclaimed.
Into the early 1970s, Namco primarily specialized in kiddie rides for Japanese department stores. Masaya Nakamura, the founder of Namco, started to direct the company toward arcade games, starting with electromechanical ones such as F-1 (1976). He later hired a number of software engineers to develop their own video games so as to compete with companies like Atari, Inc.
Pac-Man is one of the first games developed by this new department within Namco. The game was developed primarily by a young 24-year-old employee named Toru Iwatani over a year, beginning in April 1979, employing a nine-man team. It was based on the concept of eating, and the original Japanese title is Puckman (パックマン Pakkuman), inspired by the Japanese onomatopoeic 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 closed in succession. Although Iwatani has repeatedly stated that the character's shape was inspired by a pizza missing a slice, in a 1986 interview he admitted that this was a half-truth and the character design also came from simplifying and rounding out the Kanji character for mouth, kuchi (口).
Iwatani attempted to appeal to a wider audience, beyond the typical demographics of young boys and teenagers. His intention was to attract girl gamers to arcades because he found there were very few games that were played by women at the time. This led him to add elements of a maze, as well as cute ghost-like enemy characters. Eating to gain power, Iwatani has said, was a concept he borrowed from Popeye. The result is a game he named Puckman as a reference to the main character's hockey puck shape.(p142) Later, in 1980, the game was picked up for manufacture in the United States by the Bally division Midway, which changed the game's name from Puckman to Pac-Man in an effort to avoid vandalism from people changing the letter 'P' into an 'F' to spell out the F-word.( ) The cabinet artwork was also changed for Western markets.
When first launched in Japan by Namco in 1980, Pac-Man received a lukewarm response as Space Invaders and other similar games were more popular at the time. However, the game's success in North America in the same year took competitors and distributors by surprise. A frequently-repeated story claims that marketing executives saw Pac-Man at a trade show before its release and completely overlooked both it and the now-classic Defender, seeing a racing game called Rally-X (which also involves collecting items in a maze) as the game to outdo that year.
Pac-Man quickly became more popular than anything seen in the video game industry. The game was estimated to have had 30 million active players across the United States in 1982. In a 1983 interview, Nakamura said that though he did expect Pac-Man to be successful, "I never thought it would be this big." It overtook Asteroids as the best-selling arcade game in North America, grossing over US$1 billion in quarters within a year, surpassing the highest-grossing film of the time, Star Wars. Arcade machines retailed at around $2400 each and sales totaled around $1 billion (equivalent to $2.61 billion in 2018), within 18 months of release. By 1982, 400,000 arcade machines had been sold worldwide, and an estimated 7 billion coins had been inserted into them. The combined sales of counterfeit arcade machines was nearly as high as the original. United States revenues from Pac-Man licensed games and products exceeded $1 billion.
Toward the end of the 20th century, the arcade game's total gross consumer revenue had been estimated by Twin Galaxies at more than 10 billion quarters ($2.5 billion), making it the highest-grossing video game of all time, beating out Space Invaders.( ) In 2016, USgamer calculated that the machines' inflation-adjusted takings were equivalent to $7.68 billion.
Pac-Man was awarded "Best Commercial Arcade Game" at the 1981 Arcade Awards. II Computing listed the Atarisoft port tenth on the magazine's list of top Apple II games as of late 1985, based on sales and market-share data. In 2001, Pac-Man was voted the greatest video game of all time by a Dixons poll in the UK.
The game of Pac-Man is regarded as one of the most influential video games of all time; its title character was the first original gaming mascot, the game established the maze chase game genre, it demonstrated the potential of characters in video games, it increased the appeal of video games with female audiences, and it was gaming's first broad licensing success. It was the first video game with power-ups, and the individual ghosts have deterministic artificial intelligence (AI) that reacts to player actions. It is often cited as the first game with cutscenes (in the form of brief comical interludes about Pac-Man and Blinky chasing each other),:2 though actually Space Invaders Part II employed a similar style of between-level intermissions in 1979.
"Maze chase" games exploded on home computers after the release of Pac-Man. Some of them appeared before official ports, and garnered more attention from consumers, and sometimes lawyers, as a result. These include Taxman (1981) and Snack Attack (1982) for the Apple II, Jawbreaker (1981) for the Atari 8-bit family, Scarfman (1981) for the TRS-80, and K.C. Munchkin! (1981) for the Odyssey².
Pac-Man also inspired 3D variants of the concept, such as Monster Maze (1982), Spectre (1982), and early first-person shooters such as MIDI Maze (1987; which also had similar character designs).:5 John Romero credited Pac-Man as the game that had the biggest influence on his career; Wolfenstein 3D includes a Pac-Man level from a first-person perspective. Many post-Pac-Man titles include power-ups that briefly turn the tables on the enemy. The game's artificial intelligence inspired programmers who later worked for companies like Bethesda.
Atari, Inc. licensed the home rights and developed versions of Pac-Man for its Atari 2600, Atari 8-bit family, and Atari 5200 systems. Ports to other systems were published under the Atarisoft label: Apple II, Commodore 64, VIC-20, Intellivision, IBM PC, Texas Instruments TI-99/4A, and ZX Spectrum.
One of the first ports was the March 1982 release of the much-maligned port for the Atari 2600, which only somewhat resembles the original and was widely criticized for its flickering ghosts, and several design and implementation choices. Nonetheless, seven million copies of this version of Pac-Man were sold at $37.95 each, becoming the best-selling game of all time on the console. While enjoying initial sales success, Atari overestimated demand by producing 12 million cartridges, of which 5 million went unsold. Richard A. Edwards reviewed the Atari 2600 version in The Space Gamer No. 53. Edwards commented that "If you must have Pac-Man for your home, then this is it, but if you're hesitant, there are enough differences in this version to suggest passing it by." The port's poor quality damaged the company's reputation among consumers and retailers, becoming a contributing factor, alongside Atari's E.T. the Extra-Terrestrial, to Atari, Inc.'s decline and the North American video game crash of 1983.
Namco later produced versions for the Nintendo Entertainment System, Game Boy, Game Boy Color, Game Gear, and Neo Geo Pocket Color. Namco ported the game to the Famicom in 1985, but, as they had no North American operations at this time, they had to license Atari—under the Tengen name—to release certain Namco Famicom games for US audiences. The Atari release of Pac-Man was initially a licensed Nintendo cartridge in a standard gray shell, but soon afterward Atari began manufacturing unauthorized clones of the NES lockout chip and produced unlicensed NES cartridges in black shells, including Pac-Man. Nintendo eventually discovered this ruse and filed a lawsuit against Atari. In 1993, Namco released Pac-Man for the NES itself, so there are three different North American releases of the NES Pac-Man—the Atari gray cartridge, the Atari black cartridge, and the Namco version—differing only in the copyright notices on the title screen.
Guinness World Records has awarded the Pac-Man series eight records in Guinness World Records: Gamer's Edition 2008, including First Perfect Pac-Man Game for Billy Mitchell's July 3, 1999 score and "Most Successful Coin-Operated Game". On June 3, 2010, at the NLGD Festival of Games, the game's creator Toru Iwatani officially received the certificate from Guinness World Records for Pac-Man having had the most "coin-operated arcade machines" installed worldwide: 293,822. The record was set and recognized in 2005 and mentioned in the Guinness World Records: Gamer's Edition 2008, but finally actually awarded in 2010.
The Pac-Man character and game series became an icon of video game culture during the 1980s, and a wide variety of Pac-Man merchandise has been marketed with the character's image, from t-shirts and toys to hand-held video game imitations and even specially shaped pasta. General Mills manufactured a cereal by the Pac-Man name in 1983.
The game has inspired various real-life recreations, involving either real people or robots. One event called Pac-Manhattan set a Guinness World Record for "Largest Pac-Man Game" in 2004. The business term "Pac-Man defense" in mergers and acquisitions refers to a hostile takeover target that attempts to reverse the situation and take over its would-be acquirer instead, a reference to Pac-Man's energizers. The game's popularity has led to "Pac-Man" being adopted as a nickname, most notably by boxer Manny Pacquiao, as well as the American football player Adam Jones.
On August 21, 2016, in the 2016 Summer Olympics closing ceremony, during a video which showcased Tokyo as the host of the 2020 Summer Olympics, a small segment shows Pac-Man and the ghosts racing against each other eating dots on a running track.
The Pac-Man animated TV series produced by Hanna–Barbera aired on ABC from 1982 to 1983. A computer-generated animated series titled Pac-Man and the Ghostly Adventures aired on Disney XD in June 2013. As of February 2019, the series was also planned to air on Universal Kids, but it was ultimately canceled due to low coverage of NBCUniversal.
In music, the Buckner & Garcia song "Pac-Man Fever" (1981) went to No. 9 on the Billboard Hot 100 charts, and received a Gold certification for more than 1 million records sold by 1982, and a total of 2.5 million copies sold as of 2008. The group's Pac-Man Fever album (1982) also sold over a million copies.
In 1982 "Weird Al" Yankovic recorded a parody of "Taxman" by the Beatles as "Pac-Man". It was eventually released in 2017 as part of Squeeze Box: The Complete Works of "Weird Al" Yankovic. In 1992, Aphex Twin (with the name Power-Pill) released Pac-Man, a techno album which consists mostly of samples from the game.
The Pac-Man character appears in the film Pixels (2015), with Denis Akiyama playing series creator Toru Iwatani. Pac-Man is referenced and makes an appearance in the 2017 film Guardians of the Galaxy 2.
In Sword Art Online The Movie: Ordinal Scale where Kirito and his friends beat a VR Pac-Man game called PAC-Man 2024. Iwatani makes a cameo at the beginning of the film as an arcade technician. In the Japanese tokusatsu film Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Riders, a Pac-Man-like character was introduced as the main villain.
Other gaming mediaEdit
In 1982, Milton Bradley released a board game based on Pac-Man. Players move up to four Pac-Man characters (traditional yellow plus red, green, and blue) plus two ghosts as per the throws of a pair of dice.
Sticker manufacturer Fleer included rub-off game cards with its Pac-Man stickers. The card packages contain a Pac-Man style maze with all points along the path hidden with opaque coverings. From the starting position, the player moves around the maze while scratching off the coverings to score points.
Pac-Man is a playable character in Super Smash Bros. for Nintendo 3DS and Wii U. The 3DS version has a stage based on the original arcade game, called Pac-Maze. A Pac-Man Amiibo figurine was also released by Nintendo on May 29, 2015. Pac-Man later returned as a playable character in Super Smash Bros. Ultimate.
Within the mathematical research field of dynamical systems, a new kind of renormalization called "pac-man renormalization" was introduced by Dzmitry Dudko, Mikhail Lyubich, and Nikita Selinger. The name was inspired by the visual similarity of the pac-man figure to their main object of study. This theory, announced in 2017 with further advanced in 2018 made significant advances in the study of the famous Mandelbrot set. 
Remakes and sequelsEdit
Pac-Man is one of the few games to have been consistently published for more than three decades, having been remade on numerous platforms, and spawning many sequels. Pac-Man has been included in Namco's long-running Namco Museum compilations as well as Microsoft Return of Arcade. Downloads of the game have been made available on game services such as Xbox Live Arcade, GameTap, and Virtual Console. Namco has released mobile versions of Pac-Man for BREW, Java, and iOS, as well as Palm PDAs and Windows Mobile-based devices.
Pac-Man has numerous sequels and spin-offs, only one of which was designed by original designer Toru Iwatani. Some of the follow-ups were not developed by Namco either, including the most significant, Midway's Ms. Pac-Man, released in the United States in 1981. Originally called Crazy Otto, this unauthorized hack of Pac-Man was created by General Computer Corporation and sold to Midway without Namco's permission. Bally-Midway released several other unauthorized spin-offs, such as Pac-Man Plus, Jr. Pac-Man, Baby Pac-Man, and Professor Pac-Man, resulting in Namco severing business relations with Midway.
Coleco's tabletop Mini-Arcade versions of the game yielded 1.5 million units sold in 1982. Nelsonic Industries produced a Pac-Man LCD wristwatch game with a simplified maze also in 1982.
Namco has repeatedly re-released the game to arcades. In 2001, Namco released a Ms. Pac-Man/Galaga "Class of 1981 Reunion Edition" cabinet with Pac-Man available for play as a hidden game. To commemorate Pac-Man's 25th anniversary in 2005, Namco released a revision that officially featured all three games.
On June 5, 2007, the first Pac-Man World Championship was held in New York City, which brought together ten competitors from eight countries to play the new Pac-Man Championship Edition developed by Toru Iwatani. Its sequel was released November 2010.
Namco Networks sold a downloadable Windows PC version of Pac-Man in 2009 which also includes an enhanced mode which replaces all of the original sprites with the sprites from Pac-Man Championship Edition. Namco Networks made a downloadable bundle which includes its PC version of Pac-Man and its port of Dig Dug called Namco All-Stars: Pac-Man and Dig Dug. In 2010, Namco Bandai announced the release of the game on Windows Phone 7 as an Xbox Live game.
For the weekend of May 21–23, 2010, Google changed the logo on its homepage to a playable version of the game in recognition of the 30th anniversary of the game's release. The Google Doodle version of Pac-Man was estimated to have been played by over 1 billion people worldwide in 2010. Google later allowed access to the game through a separate web page.
In April 2011, Soap Creative published World's Biggest Pac-Man working together with Microsoft and Namco-Bandai to celebrate Pac-Man's 30th anniversary. It is a multiplayer browser-based game with user-created, interlocking mazes.
In 2016, an in-app version of Pac-Man was introduced in Facebook Messenger. This allows users to play the game against their friends while talking over Facebook.
