Pac-Man Plus is an arcade game released by Bally Midway in 1982, and it is the 4th title in the Pac-Man series of games. Like Ms. Pac-Man, this update to the original game was created without Namco's authorization.
Pac-Man Plus had the same basic goal of all of the early Pac-Man games: to eat all of the pac-dots and power pellets before Pac-Man is caught by the monsters. Just like the other early Pac-Man games, power pellets could be eaten so that the ghosts would become vulnerable and turn blue for a short length of time. Despite advertising stating that Pac-Man Plus was "Exciting!" and "New!"[1] this game is actually just a modifier chip for the original Pac-Man, and the gameplay is essentially identical to it, with only minor gameplay tweaks and altered graphics (the maze is light green, compared to the original blue, Blinky is slightly cross-eyed, and the fruits have been replaced by alternative objects, including a can of Coca-Cola). The most significant changes in the gameplay, however, is that eating a bonus fruit causes the ghosts to become vulnerable and invisible, doubling the score for eating them; and that eating power pellets would often have unpredictable effects (such as turning only three ghosts blue or turning the maze invisible).
Because there were so few differences between Pac-Man and Pac-Man Plus and because the game was released right before the video game crash of 1983, Pac-Man Plus was never ported to home video game systems or computers. However, there have been efforts by some homebrew game developers to port Pac-Man Plus to classic game consoles such as the Atari 2600,[2] and more recently the Atari 5200 [3] and the Atari 7800.[4] In addition, Jakks Pacific released a new Pac-Man TV Games collection that featured Pac-Man, Pac-Man Plus, Super Pac-Man, and Pac & Pal.[5] Pacman Plus is featured on tv games "Pacman Gold Edition."

The height of Pac-Man's popularity introduced a new wave of arcade bootlegging, where unauthorized copies of Pac-Man were manufactured at a tremendous rate to illegally cash in on the fad. While many bootlegs were carbon copies of the original, some bootlegs (such as Hanglyman and New Puck-X) actually modified the game to introduce some new wrinkles in an effort to make it more interesting and attract expert players who wanted a new challenge.
While Bally Midway proceeded with the manufacturing of Ms. Pac-Man against Namco's wishes, they also sought to stem the flow of bootlegs by producing an officially licensed upgrade to Pac-Man, which they named Pac-Man Plus. As far as Namco was concerned, Super Pac-Man was the true sequel to Pac-Man, and this upgrade was also unauthorized. Nevertheless, Midway proceeded to sell Pac-Man Plus to feed the demand in the U.S. for more Pac-Man products, as Super Pac-Man wasn't performing as well as Midway hoped.
The changes to Pac-Man Plus range from drastic to subtle, and are all detailed below. Since Pac-Man Plus was merely seen as a stop-gap solution to the bootleg arcade problem, and Ms. Pac-Man gained in popularity by the time Plus was released, it wasn't seriously considered for home conversion. No official conversions were made around that time. More recently, homebrew programmers have released conversions of older Atari games in to Pac-Man Plus. It was also included in Jakks Pacific's 2006 Super Pac-Man TV game.

The basic rules of Pac-Man are unchanged. You must complete eat stage by consuming every dot and power pill on the screen. You lose a life by touching a ghost, but you can consume them for a brief period of time after you eat a power pill. Here are a list of the changes.

While dedicated patterns for Pac-Man Plus machines are rare, some do exist. Due to the random nature of the ghosts' behavior once a bonus item is eaten, most patterns will forego one or both of the bonus items. Examples of these patterns can be found on the Arcade patterns page.
AtariAge.com forum member PacManPlus is a programmer who is largely responsible for converting many versions of Pac-Man on various Atari platforms in to Pac-Man Plus. In this case, he took Rob Kudla's Ms. Pac-Man hack known as Mr. Pac-Man, and further hacked it into Pac-Man Plus. Meanwhile, forum member Nukey Shay has been diligently hacking the core of Ebivision's Pesco ROM for the 2600 in to Pac-Man, and added the variations contained in Pac-Man Plus (as well as Hanglyman) in to the program.
PacManPlus took the well received conversion of Pac-Man for the Atari 5200 (and the Atari home computers) and hacked it in to Pac-Man Plus with a great deal of success.
Just to complete the trilogy of systems, PacManPlus took the Ms. Pac-Man ROM for the 7800 and first successfully converted it into Pac-Man, and then took it one step further and made Pac-Man Plus.
In 1982, Pacman Plus is no put on the Arcade on MAME
