Here's how Wikipedia describes a perfect game of Pac-Man:
A perfect Pac-Man game occurs when the player achieves the maximum possible score on the first 255 levels (by eating every possible dot, power pellet, fruit, and enemy) without losing a single life, and using all extra lives to score as many points as possible on Level 256. The first person to achieve this score was Billy Mitchell of Hollywood, Florida, who performed the feat in about six hours. Since then, six other players have attained the maximum score in increasingly faster times.
From my perspective, there's three stages to achieving a perfect game:
The first 21 boards, where you eat dots and powerpills, and the ghosts turn blue and you can eat them, along with all the other dots and fruit. These screens vary in speed, and also vary in terms of how long the ghosts turn blue. In some instances you have one second to eat all four ghosts.
What follows from screen 22, are 234 boards of the same thing. This is known as "crossing the desert". The powerpills don't work and the ghosts cannot be eaten. You have to get a pattern in your head, learn it, and execute it 234 times over and over and over. No mistakes, no room for error. You are the loneliest gamer in the world at this point no one can help you, you are fighting your own mind - if it wonders, you're in trouble.
And then of course, finally, the infamous "split screen" at screen 256. (Bear in mind that in order to get a perfect score, you have to arrive at this point on your first man. Every dot, every powerpill, every ghost, every fruit. Without losing a life). The game literally "crashes" due to eight-bit coding and an expectation from Iwatani-san that no one would ever get there anyway. In short, the garbage displayed on the screen means that there aren't enough dots to eat for the game to register that the level is complete. There are dots there, but some are hidden in the mess on the right hand side. You eat what you can, then kill off Pacman, and do it again with your remaining lives.
So, do those three things, and six hours or so later, you get your perfect score of 3,333,360.
An achievement in itself...
But what many people don't appreciate, is that whilst anyone can get a perfect game of Pacman - all the patterns are out there on YouTube if you can be bothered to learn them - not everyone can actually play the game to the point where you can manipulate the ghosts at will and put them where you need them to be in order to max out the game.
What makes Jon's achievement so extraordinary, is the way he's done it. He's never used a pattern up to the 21st board and plays them all totally "freehand". Very few players can do this, and without question, no one has ever got a perfect game without using patterns during those first boards.
Six people have achieved the perfect score on Pacman to date. But most of them have learned patterns from other players to be one of the half dozen people in that elite club. But ask any other "perfect" player to cope with the game when their patterns break down, and the vast majority can't. They've literally read a book, learned how to do it, and executed it. Of course, if those patterns break down, the game will typically end, because players don't know how to recover when their game goes outside of the parameters of what they've learned. Jon mastered the game the old school way. He knows what to do because he's always played the game on the fly, and has got into the underbelly and soul of the game.
There's also something called "rack advance" in the game. This is where you can open up the machine (or do it in MAME), press a dipswitch and cycle through the screens, so that you can start on any of the 256 levels you want. Of course, if you have this sort of access to a machine, this means that you can advance the game to the split screen at level 256 where the game ends, and start there to practise that screen without having to plough through 255 levels to get to that point some six hours later. Jon has never used Rack Advance, he wanted to work it all out by playing, and dying, and playing and dying.
Add to that his admirable decision to only do a perfect game in a live environment. He's always been insistent that if the score wasn't achieved "live" in front of witnesses, then it wouldn't count for much, because back in '83, that's how it was done. The pressure of a live environment added to the difficulty of getting a score.
I dread to thing of how many hours I've watched Jon playing Pacman at live events both here in the UK and America. I've witnessed some heartbreaking moments with him (even just the day before he achieved his score, he got to 2.2 million and his pattern broke down crossing the desert). It's hard to know what to say when someone doesn't achieve something they've worked so hard to get. Thankfully I don't have to struggle to console him ever again about Pacman! More than any other gamer he's paid his dues and deserves a huge amount of credit. Not to mention the money he's raised for charity along the way.
It's really easy to underestimate what Jon has achieved here - his is a massive, massive achievement, really off the scale. I can't see anyone else
ever getting a perfect game of Pacman in the way he went after his goal.
Jon Stoodley joined an elite club last night on 22nd August 2015, and he did it in style.
Congratulations mate. You f**king did it.
