You probably think you know how it went down. A lone genius sits in a dark room, writes some code, and suddenly the entire world is obsessed with a yellow circle eating dots.
It makes for a great movie scene. But honestly? It’s not exactly how it happened.
When people ask who made Pac-Man game, the name that immediately pops up is Toru Iwatani. He’s the face of the franchise, the guy who famously said the design was inspired by a pizza with a missing slice. But Iwatani wasn't working in a vacuum. He was a young designer at Namco, a company that, at the time, was mostly known for mechanical driving games and a Space Invaders clone called Galaxian.
He was only 24.
Think about that for a second. At 24, most of us are struggling to figure out how a 401k works. Iwatani was busy trying to save the arcade industry from itself. In 1979, arcades were loud, dirty, and filled with "boys' games" about shooting aliens or blowing up tanks. It was a masculine, violent vibe. Iwatani wanted something different. He wanted a game that couples could play—a game that girls would actually like.
He didn't do it alone, though. While Iwatani was the visionary and the "father" of the game, he led a small, specialized team of nine people at Namco. This included programmer Shigeo Funaki, who did the heavy lifting of turning Iwatani’s sketches into working logic, and Toshio Kai, the man responsible for that iconic, waka-waka sound that still lives rent-free in our heads forty years later.
The Pizza Myth vs. The Reality
Everyone loves the pizza story. Iwatani has told it a thousand times: he was hungry, ordered a whole pizza, took one slice, and saw the shape of a character.
It’s a classic. It's also, by Iwatani's own admission in later years, a bit of a "half-truth" designed to make the marketing easier.

In reality, the design of Pac-Man (originally Puck-Man in Japan) was a simplification of the Japanese kanji character for "mouth" (kuchi). While the pizza story helped humanize the design process for the press, the actual development was a grueling 18-month cycle. That was an eternity in the late 70s. Most games back then were whipped together in three or four months.
Iwatani’s team spent a huge chunk of that time on the ghosts. They aren't just random enemies. If they were, the game would be impossible. Each ghost has a personality, and that’s thanks to the specific AI programming handled by Funaki.
- Blinky (Red): He’s the chaser. He follows you directly.
- Pinky (Pink): She tries to ambush you by heading for where you’re going to be, not where you are.
- Inky (Cyan): He’s the wildcard. His movement is based on both Pac-Man’s position and Blinky’s position.
- Clyde (Orange): He’s "stupid." He chases you until he gets close, then gets scared and retreats to his corner.
This wasn't just "game design." It was psychological warfare. By giving the ghosts individual behaviors, Iwatani ensured the game felt like a living thing rather than a math problem.
Why Namco Almost Didn't Release It
It’s hard to imagine now, but Namco wasn't sold on the idea.
When the internal reviews happened, the higher-ups were skeptical. They thought the game was "too cute." They wanted more "action." Remember, this was the era of Defender and Asteroids. A yellow circle eating cookies in a maze felt... soft.
But Iwatani pushed. He insisted on the "Power Pellet" mechanic, which was inspired by Popeye eating spinach to gain strength. This was a massive shift in game theory. For the first time, the hunted could become the hunter. It gave the player a sense of empowerment that was totally unique for 1980.
When the game finally hit Japanese arcades in May 1980, the reaction was actually pretty lukewarm. It did okay, but it wasn't a smash. It wasn't until Midway (a US distributor) saw the game and brought it to North America that the "Pac-Mania" phenomenon truly exploded.

The Naming Fiasco: From Puck to Pac
Let's talk about the name.
In Japan, the game was Puck-Man. The name came from the Japanese phrase paku-paku, which describes the sound of a mouth opening and closing.
When the game came to the States, Midway executives were terrified. They realized that "Puck" was one scratched-out "P" away from being a very different word. Vandalism was a big deal in 1980s arcades. To save themselves the headache of obscene cabinets, they changed it to Pac-Man.
It was a genius move, albeit a defensive one.
The Technical Wizardry of 1980
The hardware running Pac-Man was incredibly primitive by today’s standards. We’re talking about a Zilog Z80 processor running at about 3 MHz. Your modern toaster probably has more computing power than the original Pac-Man cabinet.
Because the memory was so limited, the team had to be brilliant with their shortcuts.
Take the "Level 256" glitch. Most people know about the "kill screen" where the right side of the screen turns into a garbled mess of symbols. This wasn't intentional. The game used an 8-bit integer to store the level number. When the game tries to load level 256, the counter overflows back to zero, but the routine that draws the fruit (the level icons) still tries to draw 256 items. It floods the memory, overwrites the screen data, and essentially breaks the game.

Iwatani and his team never expected anyone to get that far. It was a game designed for three-minute sessions, not marathon runs.
The Legacy of the Team
While Toru Iwatani eventually left game development to become a professor at Tokyo Polytechnic University, the DNA of his team’s work is in every game you play today.
They invented the "power-up."
They pioneered non-violent gameplay.
They created the first recognizable "character" in gaming history.
Before Pac-Man, you played as a "ship" or a "paddle." After Pac-Man, you played as a person (or a circle) with a name, a family (eventually), and a personality.
Actionable Insights for the Modern Gamer and Creator
If you're looking at the history of who made Pac-Man game and wondering what it means for you today, there are a few real-world takeaways:
- Iterate on "The Hook": Iwatani didn't invent the maze game, but he added the "reversal" (the power pellet). If you're creating something, don't reinvent the wheel; just add the one feature that flips the script.
- Study the AI: If you're a developer, look at the ghost logic. Simple, predictable patterns combined together create the illusion of complex intelligence. You don't need a supercomputer to make an enemy feel "smart."
- Think Outside Your Demographic: Pac-Man succeeded because it looked for an audience that everyone else was ignoring. While every other dev was chasing the "hardcore" gamer, Iwatani was looking at everyone else.
- Embrace Constraints: The "Kill Screen" is a reminder that even the most iconic pieces of software have limits. Don't let perfectionism stop you from shipping. Even a "broken" game can change the world.
The story of Pac-Man isn't just about a yellow ball. It’s about a small group of Japanese engineers who decided that games could be more than just digital shooting galleries. They made it colorful. They made it funny. And most importantly, they made it for everyone.
If you want to experience the original vision, track down an actual arcade cabinet or a "pixel-perfect" port. Avoid the mobile versions that add too many bells and whistles; the purity of Iwatani’s 1980 design is where the real magic is. Observe how the ghosts move. Once you see the "logic" of Blinky and Inky, you’ll never look at the game the same way again.
