I Spent 100 Hours In Pokemon's Game Corner To Answer This 

This guy is why they removed the game corner in future versions lol

From what I'm aware, before you even start doing anything, the game first determines if you're even allowed to win anything on the current spin at all. So even if you line up the first two 7s correctly, the last one sometimes will never line up no matter how perfectly you time it because the game has decided that this round will not pay out. You can see this for yourself if you start up a spin and then save state before stopping any columns. Sometimes you'll find that no matter how many times you reload the state, the current spin is impossible to win.

After some brief research into the game's code: There's actual 6 different "bias" sets in the games code. It's completely random and doesn't depend on which slot machine you use as it's re-generated when you play any given slot machine. Based on RNG, these biases affect what icons the reel will want to stop at. Here's the spread: Bias 0: 50% Bias 1: 9.1% Bias 2: 13.63% Bias 3: 13.63% Bias 4: 9.1% Bias 5: 4.54% Bias 5 has a significantly enhanced bias for 7's: Bias 0 7's Bias = 73 Bias 1 7's Bias = 73 Bias 2 7's Bias = 73 Bias 3 7's Bias = 80 Bias 4 7's Bias = 80 Bias 5 7's Bias = 115 If there was a way to ensure you always got the best bias set, I'm sure the record could be lowered much further. Looking at the RAM value at position 0x800D shows what bias set was selected. Theoretically someone could use that to get a feel for when they have the perfect bias, then grid attempts until they get something that feels like the best bias set. If you want a better idea than just my poor explanation, anyone more skilled or just better at understanding C code can find the decompiled code for the slot machine here: github.com/pret/pokefirered/blob/master/src/slot_machine.c

I use speed run Leaf Green's Casino for fun when I was a kid. Even when I was younger I pretty quickly realized that you can learn the muscle memory to get triple sevens pretty often, since the column patterns are always the same. I never knew how precise the timing needed to be, but it felt pretty precise. Glad to see something that I wasted time doing as a kid become an actual competitive speed run! Looks like there's a lot more RNG to this game than I thought as a kid!

ending gave me such a loud schadenfreude laugh. great video.

CELADON GAME CORNER GET WHAT I'M OWED

See you in the Yahtzee speedrun

I tend to lurk in a lot of these videos, and I've never attempted speedrunning personally, but I do find it really intriguing that with how dissected these codes are nowadays, and how optimized these things are, that things are still being discovered. In a way, it kinda reminds me of Goppier's videos. While he used the game's code to figure out how to trade a Pokemon from Gen 2 to Gen 3 and make an actual IRL physical device/cable to do so, this is looking into uncharted territory in the code to find new ways to play the old game. All in all, really amusing, and I'd be curious how much more there might be to find in this. Also I saw your comment about RSE and I'd be really curious to see just how far that rabbit hole goes, as someone who's coding knowledge is at a very basic/script kiddy level.

Bruh that ending lol

Is this the beginning of a rivalry arc?

I think this will get you addicted to slots IRL XD

I saw your video from your short, really liked the idea! Your humor was spot on and I definitely laughed while watching your video. Interested to see where you're going to go from here!

Um, why are you waiting for the coins to pay out. If you press the start button it skips the coin count down (there is a small delay before it works tho)

Not a fan of how he tried to consistently psych you out. Not very good sportsmanship.

My lucky machine is bottom right above the gentleman

Thank goodness for Voltorb flip also there are some ways to get all 2s and 3s. But if you’re starting out, I’d say flip over the cards that have 0 Voltorb in them, then if the numbers add up to 5 on both the numbers and Voltorb, you mark them all with Voltorb. I’ve done this before and it helped me get through the first level, although the numbers are always at random spots so it might not be the same as mine. 😅

OMG I LOVE GAME CORNER I SPENT HUNDREDS IF NOT THOUSANDS OF HOURS PLAYING THE SLOT MACHINES EVERYTIME I GOT A ROW OF 7S MY DOPAMINE LEVELS ROSE UP TO ASTRONOMICAL HEIGHTS. BY FAR THE BEST FEATURE IN ANY POKEMON GAME BY FAR

Once I learned the infinite nugget glitch to get infinite money I did that to just buy all the coins lol Now I learned the RNG Manipulation calibration to then rng manipulate the game to get me a shiny charmander in a new file once I have that I can trade to emerald and clone it The only think I can't seam to find info on is rng manipulating for a shiny eevee!

So I notice none of these make use of the start button paying out remaining coins without having to wait, is there a rule against it?

Does anyone know if you can rig the odds of the RSE casino games?

99.999% of gamblers quit before making it big ;(

I love u, asian minecraft steve

Súper underrated

If it's actually true that the difficulty of the slots is somehow different every time you play, then that's just cruel to the kids who spent tons of time trying to get good at them LOL.

Another banger

Do this work in Emerald? I can probably just buy the coins with money but I wanna beat casino at least once.

Fantastic

sooo.. work harder not smarter then?

I have 2000 coins I got in ten minutes

I kid you not I made 1600 on one machine , left and misclicked on the wrong item now I can’t win at all
