Pac-Man is an action video game developed and published by Namco on 1980-05-22, and distributed by Midway in the USA in 1980-10-26. Pac-Man is the best-selling arcade cabinet to date, and the second most profitable. Despite being so lucrative, the game's designer Toru Iwatani did not receive a bonus or even official recognition from Namco for his creation.
I remember first playing this game in the mid-1980s. I was with my mother and brother, I think at a laundromat in Pontiac. I remember my brother playing and getting to the second stage, but I, being 3-years-younger, couldn't get past the first. I've since watched people who are really good play Pac-Man in arcades, but I've never had much of a desire to get good myself. The game is just too primitive to keep my interest.
I do not own the game. I've never tried hard to get a decent score, and I've never even come close to the kill screen.

— This section contains spoilers! —
- The game is pretty solid. It remains challenging and fast-moving the entire time you play.
- The increasingly difficult ghosts and shorter-length power pellets increase the challenge of the game at a nice steady rate.
- Adding a different "personality" to each ghost was a wonderful idea and really adds to the challenge, as did having the ghosts systematically move toward their own corners.
- Changing the bonus fruit is a nice change of pace.
- The cut-scenes between levels was a nice break in the action.
- The game has some pretty memorable sound effects and jingles.
- The game is too hard. Most players are unable to beat the first level on their first attempt, which is a bit frustrating.
- Overall, there isn't much to do with the game. You're essentially repeating the same actions the entire game.
- Since the game uses a pseudo-randomizer, players can actually just repeat the exact same movements over an over again to beat the game. In fact, this is precisely how professional players play the game, it's incredibly boring to watch.
- The game lacks a true victory condition. Sure, the kill screen ends the game, but it's insanely difficult to reach, and wasn't even intended in the first place.
- There is a minor bug with collision detection where you can sometimes pass right through a ghost.

Although Pac-Man doesn't feature credits, fans of the game have discovered the majority of the design staff.

The original arcade version of Pac-Man uses a hardware-based color PROM to determine its colors. The PROM stores a palette of 256 colors in a single byte. The red, green, and blue channels are defined by the bit pattern BBGGGRRR which allows for eight levels of intensity for red and green and four levels for blue. The display hardware could only work with an index of 16 colors chosen from the palette of 256, and even then, each background tile or sprite could only be composed of up to four colors from the index of 16. Despite having 16 possible colors to work with, the designers occupied four slots with black, resulting in only 13 unique colors. These blacks appear to be used in certain graphics to color things invisible. For example, when a pellets is eaten, the game continues to draw it, but it sets its color to black. Also, the area inside the maze walls is colored a different black than the background, although this never comes up in the game as far as I know.
In the table below I've converted the colors from the game into RBG equivalents using an increment of 36 for the red and green channels and an increment of 85 for the blue channel. As far as I know, this does not properly emulate the color PROM's method, and I'm not able to get the true binary value for each color, but it yields a fairly accurate result. More advanced emulators, like MAME probably emulate the PROM, but they also adjust each pixel based on its nearby pixels to better emulate CRTs, so they don't give a true result either.
