, who was given a limited time frame by Atari to complete the project. The technical differences between the Atari 2600 console and the original's arcade hardware—particularly the amount of available memory—presented several challenges to Frye. Given the popularity of the property, Atari produced 12 million units, anticipating a high number of sales.

While the port sold 7 million copies and is the best-selling Atari 2600 title, it was critically panned. Critics focused on the gameplay and audio-visual differences from the arcade version. Customers returned the game in large quantities. Initially, the port boosted the video game industry's presence in retail, but has since been cited as a contributing factor to the North American video game crash of 1983. It was followed by Atari 2600 ports of Pac-Mans arcade sequels.

 to navigate the round, yellow titular character, which starts each game at the center of a maze. The goal is to eat wafers scattered throughout the maze by moving Pac-Man over them while avoiding four ghosts. Each time Pac-Man comes into contact with a ghost, he dies, losing a life and reappearing at the center of the maze. When Pac-Man runs out of lives, the game ends. Four of the wafers are larger than the others and temporarily make the character invulnerable to the ghosts. During this time, Pac-Man can eat the ghosts for additional points, after which the ghosts will respawn. Extra points are also awarded when Pac-Man eats special items that occasionally appear. Once the player collects all the wafers in a stage, the level is completed and the player progress to the next level. Differences from the original include a different maze pattern and orientation. In-game items—like the wafers, vitamins, and power pills—differ from their arcade counterparts in name and appearance, but still serve the same functions.

Development

In the late 1970s, Atari acquired the rights to produce home versions of Namco's arcade games. After Pac-Man proved to be a success in the United States, Atari decided to produce a home port for its Atari 2600

 console. The company believed the conversion would be simple because the arcade's success was attributed to the gameplay rather than impressive visuals. Development took around five months; the process started in late 1981 and finished in March 1982. At the time, Atari projected that 10 million consoles were still actively used by video game enthusiasts. Atari decided to produce 12 million game cartridges, anticipating that every active Atari 2600 owner would purchase the game. Management also believed 2 million new people would purchase the system to play it, and predicted sales to reach at least 500 million United States dollar

After Atari acquired the rights to produce the game, Frye began work on a prototype version. The company wanted to release the prototype to capitalize on the 1981 holiday season.

With limited memory, Frye simplified the shape of the maze with block corners as opposed to rounded ones and a less intricate pattern of corridors. The round, white pellets in the original were changed to rectangular, brown ones on the Atari 2600. This change was to consolidate resources by using the same sprite used to create the walls. To achieve the visual effect of wafers disappearing after Pac-Man eats them, the console redraws the entire maze and wafers, excluding those that had been eaten. The sprites were animated differently to accommodate technical limitations. The Pac-Man character sprite as well as the maze and wafers sprites are drawn every frame, while the four ghosts are drawn at intervals. The four different ghosts take turns displaying on the screen and only one ghost is present at any given time, which creates a flickering effect. This effect takes advantage of the slow phosphorescent

Pac-Man met with initial commercial success, selling 7 million copies and eventually becoming the best-selling Atari 2600 title. However, purchases soon slowed and, by summer 1982, unsold copies were still in large quantities. Many buyers returned the games for refunds, and Atari was left with 5 million excess copies in addition to the returns. By 2004, the cartridges were still very common among collectors and enthusiasts—though the Sears versions were more rare—and priced at low amounts.

reviewer Danny Goodman commented that the game fails as a replica of its arcade form.

Former Next Generation editor-in-chief Neil West attributes his longtime skepticism of Atari's quality to the disappointment he had from buying the game as a child. Calling the game the top video game disaster, Buchanan credits Pac-Man as a factor to the downfall of Atari and the industry in the 1980s. Author Steven Kent

 also attributes the game, along with Atari's E.T. the Extra-Terrestrial, to severely damaging the company's reputation and profitability. Montfort and Bogost stated that the game's negative reception seeded mistrust in retailers, which was reinforced by later factors that culminated in the crash.

Poor critical reception made this game one of many decisions that led to Atari's report of a $536 million loss in 1983 and the division and sale of the company's Consumer Division in 1984. On December 7, 1982, Kassar announced that Atari's revenue forecasts for 1982 were cut from a 50 percent increase over 1981 to a 15 percent increase. Immediately following the announcement, Warner Communications' stock value dropped by around 35 percent—from $54 to $35—amounting to a loss of $1.3 billion in the company's market valuation
