It’s probably a very rare person who has never played Pac-Man. Even for those who may have missed it in the 1980s, Pac-Man has been re-made on nearly every video game platform since then. Pac-Man even appeared on the front page of Google (as a playable game) on Pac-Man’s 30th anniversary.
However, for those few who are unfamiliar with the game, here are the basics. You, the player, control the yellow, circular Pac-Man using either keyboard arrows or a joystick. The goal is to move Pac-Man around the maze-like screen gobbling up all 240 dots before the four ghosts (sometimes called monsters) get you.

The four ghosts are all different colors: Blinky (red), Inky (light blue), Pinky (pink), and Clyde (orange). However, they all turn dark blue when Pac-Man eats one of the four power pellets available on each level; the pellets enable Pac-Man to eat the ghosts.

Occasionally, fruit will appear on the screen. If Pac-Man gobbles those up then he earns a point bonus, with different fruit worth different values.

While all this is happening, Pac-Man makes a wocka-wocka sound that is nearly as memorable as the yellow character himself.

When first launched in Japan by Namco in 1980, the game received a lukewarm response, as Space Invaders and other similar games were more popular at the time. However, the game found far more success in North America. Pac-Man’s success in North America took competitors and distributors completely by surprise in 1980. Marketing executives who saw Pac-Man at a trade show prior to release completely overlooked the game (along with the now-classic Defender), while they looked to a racing car game called Rally-X as the game to outdo that year. The appeal of Pac-Man was such that the game caught on immediately with the public; it quickly became far more popular than anything seen in the game industry up to that point. Pac-Man outstripped Asteroids as the best-selling arcade game in North America, grossing over $1 billion in quarters within a decade, by the end of the 1980s, surpassing the revenues grossed by the highest-grossing film “Star Wars”. The player controls Pac-Man through a maze, eating pac-dots (also called pellets). When all pac-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 and the Pac-Man itself withers and dies. When all lives have been lost, the game ends. Pac-Man is awarded a single bonus life at 10,000 points by default.
