1. Pac-Man's Original Name: Did you know that the game we now know as Pac-Man was initially called "Puck-Man" in Japan? The name was changed when it came to the U.S. to prevent vandals from altering the 'P' to an 'F.'

 The Ghostly Quartet: Inky, Blinky, Pinky, and Clyde aren't just random ghost names. Each has a distinct personality and unique AI behavior, making the game even more challenging.

. A Perfect Game: In 1999, a player named Billy Mitchell achieved the first perfect Pac-Man score of 3,333,360 points. He reached the 256th level, where a bug causes half the screen to turn into random symbols.

1. The 256 Split Screen: On the infamous level 256, there's a split-screen glitch. Only one side is playable, making it virtually impossible to complete. But Billy Mitchell managed it through a glitch exploit.

2.1. Ms. Pac-Man's Origins: Ms. Pac-Man wasn't an official sequel; it was developed by a different company and originally called "Crazy Otto." Namco later bought it and rebranded it as Ms. Pac-Man. 2.

 The Power Pellet: The big dots in Pac-Man are officially called "Power Pellets." When eaten, they turn the ghosts blue and vulnerable, allowing Pac-Man to eat them.

The First Kill Screen: Due to a level-256 glitch, the original Pac-Man had a "kill screen" that ended the game prematurely, stumping many early players.

Pac-Man Fever: In the early '80s, Pac-Man was such a sensation that it inspired a hit song, "Pac-Man Fever" by Buckner & Garcia.

Pac-Man's Creator: Toru Iwatani, the creator of Pac-Man, was inspired by the concept of eating to relieve stress. Hence, he designed a game where you eat to win.
