I think I posted this before about how some video games, you can learn the RNG pattern, and by doing a certain sequence of button pressing, save/reloading, you can guarantee a rare item in a treasure chest. Somebody told me some advantage was to be gained by doing this on Pacman. I remember doing this to cause a certain rare event to happen in game as well.

Couldn't have been the original Pacman as there really wasn't anything random in their movements or any "surprises" available point-wise.

Yeah, I heard about the case in the local news because they were initially caught in STL. But didn't get a clear idea on what they did until now. Pretty crazy.

Pretty interesting article, thanks for posting. It makes sense, though cracking the inputs to the "random" function would be pretty crazy, unless they got an old machine and the other machines in play matched the code. Then it's simply plug and chug. Funny the "government regulation" allowed static time clocks in the machines to have such a large impact on the "randomness" of the results.
Playing it correctly means you've already won.

The only "rare event" I can think of in Pac-Man is the "kill screen" - the game designer probably never expected anybody to get through level 255, so he saved the level number as an unsigned byte; as a result, when you get past level 255, the game thinks the next level is "level zero" and half the screen is garbage.

Of course, this assumes you are talking about the arcade version; it's possible that some ports may have some easter eggs hidden in them. (I know of three Atari 2600 games off the top of my head that have easter eggs - Adventure (there's a 1-pixel "dot" that's the same color as the background; if you can get it to a certain point, you can access a screen with the designer's name on it), Yars' Revenge (when you destroy the main ship, the "Ghost of Yars" appears, and it's possible to lock up the game with your score replaced by the designer's initials, forward and then backward), and Space Invaders (if you score zero on level 13 - not an easy feat, as you have to launch all 30 of your missiles without hitting anything - then the designer's initials appear in place of one of the cities at the end).)

It might have been another game that came out in the 80's, but that's before my time so I don't remember the exact game. However there is an RNG glitch you can do in Final Fantasy XII.

"You must not open the following four chests from the
beginning of the game until reaching access to the
Necrohol Of Nabudis, where the spear resides:
1.The chest in front of Old Dalanís place in Lowtown.
2.Once inside the palace in the Cellars, the left
chest in the southeast corner contains an elixir.
Do not open it. Or either just to be safe.
3.Once youíve been captured and thrown in Nalbina
Dungeon, one of the chests looks slightly different
than the others. Do not open it. The other two chests
will contain a gambit and a Tourmaline Ring.
4.There are 16 chests on Phon Coast aligned in four
rows of four. One of these is the forbidden chest.
Do NOT open any of them, period."

It was the first one of it's kind where not opening certain chests in the game led you to getting the best weapon. There were more ways to manipulate the RNG in this game to get the best stat increases in a level up, or to force a certain item in a chest.

This was very interesting as they are exploiting a PRNG weakness. Did they download every screen display outcome and develop a map of clumped winners so the buzzer would work? I wonder how much computing power it takes to efficiently run through every combination on the chip and develop a "map".

I once walked in on my brother doing some sort of double up game in one of the final fantasys.
Bet max to double up, Winner! Save.
Bet max to double up, Loser, power off, power on & try again.
$1700, 18, 19, 1920, 40, 60,... :/ Thx 'Do it again'. I'll try

I did this once! Was a long ass night. In the later versions of the game, they fixed that code, so it just went for infinity.
