Did This INFINITE LOOP Get Me BANNED From MASTER DUEL?! | Yu-Gi-Oh! Ruling Twitch Highlight 

Konami has had multiple video games to learn the bullshit us players can pull off, not to mention all the degenerates in the tournaments.

Damn, Konami was incredibly thorough when they programmed this game. I'm genuinely impressed.

The games coding impresses me, but not nearly as much as the creativity of some of the loops. Some I was aware of but this is wild. 🤣

Dire is becoming my favorite character in this series

Konami Intern: "Bro, please just stop. Come on"

Connection failed definitely seems like a last resort type of thing. If it was a memory leak the game would slow down, but also I don't think it gets even close to matching the memory you'd use in an average higher level game. There's simply not enough happening to use up that much memory, specially in a streamer's computer. I'm too lazy to check but I wonder what the total activations (Morphing, All out and Deep seated combined) were in both instances of the test. So far we've seen it immediately kill an automatic no chain loop with skill drain, and cap activations and chain links at 10 and 16 respectively, so this test seems like a definite outlier just outright killing the match.

coder is a mad scientist trying to create a superweapon but it keeps exploding in his face haha

The game likely has a timer that runs on the background when the player timer is not running and that gets reset every time your player timer goes down, so what's probably happening here is that the game uses that timer as a failsafe with something like "If (failSafeTimer > 5 minutes) {make the current player discconect}". This is probably why the first time you died after 11 activations and the second one after more activations, the pot likely took less reveals to trigger on the first couple of activations or you had less cards in deck to begin with, so that resulted in more activations happening in the same timeframe.

More than likely the game has a fail safe for infinites where if the same action leads to the same result which incurs the same action, it disconnects. Just in case they overlooked something

Konami probably is using DFS loop detection, which would explain how they can stop all types of loops without hard coding them, and why there is an anti memory leak failsafe that causes a connection issue, since DFS loop detection takes up a lot of memory

Coder is really out there bug testing the crap out of this game basically for free.

Six Sam Players: I want to do my combo 100 times and get plenty of counters. Master Duel: So you have chosen death.

Your content is great bro. Is fun watching you figure this stuff out with chat.

There's a clause in the official rules that infinite loops with no net value do not resolve like the Pole Position issue. Realistically All Out Attacks would destroy itself once it reached an infinite loop

There is the possibility that the game is coded to empty it's memory in a way that works off of different actions that were taken, which for example would explain why it makes multiple chains to resolve 17+ mandatory effects. But as you resolve the same couple of actions over and over with this loop the game might not empty it's memory as there are still actions resolving, causing either the connection to fail to prevent a stream of overlapping data your opponents machine might not be able to handle. Or it might just do that as a smoke screen, basically just lying to you to condition you to not use those decks as the game engine might have no way to correctly handle those, admittetly extremely rare, cases of unstoppable loops.

Of course it knows about the Morphing Jar 2 loop, there's enough banned cards due to a looping FTK outside of the cards that themselves loop, they're going to account for it.

I assume what happened there at the end was that the game recognised that you had only swords of deep seated and morphing jars in the deck and forced a loss upon you. The reason the amount of times morphing jar was different every time is because the amount of times morphing jar had to activate to only leave the swords and itself in the deck was random.

The interesting thing here is that All-Out Attacks should have been destroyed by game mechanics, yet it wasn't. Though technically the game state could be different with each chain, since it varies how many Sword of Deep Seated there are in the deck/GY when the next part of the loop starts.

Seems unlikely to be a memory leak directly causing the disconnect, that would look more like the game slowing down until it crashes, but forcing a disconnect *could* be an anti-memory leak failsafe if this is actually making the game take up more memory over time. I think more likely though it's unrelated to memory issues and instead it's some other sort of failsafe that forces a disconnect to prevent neverending duels.

Konami like, "You can't shuffle Morphing Jar #2 into the deck if you don't have a deck" Also I might imagine that Konami has something that says, "If you use the same card effect like 15 times in a single turn then it's most likely an infinite loop" and gives you an auto-loss. Infertnity players on Xyz Festival Watch. If you want to do more testing you should have the opponent run Dark Designator so they can search the required pieces for you.

This game is too damn smart, it’s ridiculous Also the Connection Failed message reminds me of what happened to someone who tried fusing over 100 monsters into one fusion (chimeratech over dragon I believe) so I think it is a memory thing, like it’s too much information to process

Maybe the "connection failed" error happened because there's a check to count how many cards effects happened since the last time a player played a card and, once it hits a certain number, assumes it's an infinite loop and ends the duel.

what I beleive it happens, all your cards in deck have ID attached to it the game checks your stats at every chain start and end if nothing changes ( hand, field, grave, banish, extra, lifepoints ) or you keep "shuffling" your deck they force an end to it after a limit is exceeded

Haha, you know, I think it says something about the game that pretty much all of these loops involve old cards..lol, it really was a wild time back then.

My theory is that it reads the timer isn’t going down for a set period of time and disconnects you based on that.

Whoever said it was a memory leak is 100% wrong lol. This is probably a check with in the mandatory effects resolving. If the same cards are causing an infinite loop then it might just disconnect you as like a final fail safe. Eg it looked ahead and it saw that morphing jar #2 and the equip spell creating the same exact chain more than X times so it made you quit. Try this with like 4-5 different cards to confirm.

IIRC I believe this also happens in LOD: LE. To clarify: it stops if there are no cards currently in your deck. (edit) I made this comment before your second test. But I do remember something similar happening in LOD: LE. I didn't bother doing further testing after I saw that the combo ends for reasons(???). I was also using it in conjunction with Needle Worm. The combo would end before my opponent would get decked out.

Grass is greenest.

New meta: Eldlich strikers + morphing jar 🤩

Damn man they knew about morphing jar#2 holy shit

i use morphing jar 2 combo with flip monsters as princess of tsurugi and des koala, along with buvonic vermin and gravekeeper's scout to swarm the field

It can’t result in no game state because then all-out attack is stopped. If you had hiro’s shadow scout then it continues the loop

Back in the day. When MRL first came out, I dueled against one of my friends at locals and we got stuck in a morphing jar #2 sword of deep seated loop. Mj2 resolves then the sword goes on top. We didn't know back then. 😂

I think the AI confuses the Loop with a error of performance thus forcing an end to the connection the same way you shut the power of your console when the console freezes.

... Yeah. I ran a deck that worked off the combo, with a hiro's shadow scout and three copies of MJ2. The idea was mill yourself down to your three MJ2s and 1 HSS, and having two monsters on the field.

I think it doesn't have to do with amount of activations. I think it's just that if enough time passes with the game playing itself (with neither of the players having any options), the game just disconnects, regardless of if it's a loop or not. It just assumes it is, and ends the match so it doesn't keep using up the servers unnecessarily.

A memory leak is highly unlikely, you would activate jar at least 100 time before any crash, that is IF there is any leak in the code

Did they ever try the monarch loop? It's not infinite, cause it requires input (so the timer does still decrease), but it loops cards back into your deck and your opponent's so it never goes to deckout (so potentially veeeeery high turn counter). In duel links when i did it in an ai duel i think it was at round 56 that it pulled the plug automatically. The loop is just having the prime monarch on the field and continuously summoning erebus the underworld monarch. Erebus, when sent to grave, can once per turn retun itself to hand, so having 2 in deck is enough to always cycle. Erebus on discarding from hand or deck 2 monarch spell/traps, can shuffle 1 card your opponent has in their hand, field, graveyard back into the deck (so they never deck out). Prime monarch can then shuffle your 2 discarded spell/traps back into the deck, so you can keep repeating it turn after turn. It's not as flashy and not really infinite because of the timer, but it would push the round counter to its limit.

Poor Dire. Hang in there!

It would actually be 5head if Konami kept in memory leaks, to guarantee no loops from happening

Yo this was actually entertaining I’m subscribing 😂

Can we get some love for Dire doing all this work

@DistantCoder toons can actually cause the game to lock itself, if you have toon black luster and 1 other toon monster in hand that is lv7 or lower, the game will let you activate toon bls effect to special and then when it tells you to tribute it will give you option to select other monster but won't actually let you select, the game then gets stuck in that moment, only way out is to surrender

I never thought this would come up for me, but I literally *just* faced off against someone who was using the Morphing Jar #2 + All Out Attacks but he was running a gambling deck intent on flipping up Dice Jar and Morphing Jar #2. But here's the kicker: WE (presumably) *BOTH* FORGOT THAT I ACTIVATED ONE DAY OF PEACE THE PRIOR TURN SO _NEITHER_ OF US COULD TAKE DAMAGE FROM THE DICE JARS!!! 🤣😂🤣 So we're just sitting there watching this loop go on constantly and milling literally *EVERYTHING* THAT WASN'T THOSE 6 CARDS just going "Uhhhhhh..." It was 3 monsters being summoned at a time too, so there was always at least 1 Morphing Jar #2 to keep the loop going. But then he either realized he was screwed or thought it would go on infinitely and he'd lose to a timeout and quit before the loop could be canceled. (It wasn't just a sudden cancel, the bad connection symbol was showing over his profile picture so they definitely left.)

The card text says "shuffle into the deck". That's can't happen of you have no deck, right?

Master Duel Loops is my new favorite segment 😂

Is it 5 reveals once the loop has been achieved?? So the game sees the morphing jar reveal without any meaningful change in game state so many times and just ends??

You can't shuffle it into the deck if you have no deck

That is incredible. Absolutely the craziest shit is possible in this game 🤣

I have a question. If we do this in opponents turn does this make them lose connection or us?

How I would code this is to save a copy of the future board state after a card resolution. so if something infinitely loopes to the same state then stop it.

i have an atack loop i realy need to test coder would ya be willing to elp

should try it with an opponents monster

I think the only "fail" I can think of is the limit on numbers regarding the attack value that a monster can achieve, allowing the very rare case where, you can destroy avramax by battle if you attack with a monster that already have the max amount of damage the game allows, in the damage step, avramax tries to match the attack, and surpass it by 3000 additional attack, but, since both monsters already achieved the maximum amount of attack, avramax is unable to surpass the damage by any amount, thus, both monsters are destroyed because they have the same amount of damage. it is very difficult to pull of anyway, so I don't think it is a concerning problem.

Oh yeah, that seems like a timeout problem, but it's kinda weird considering how many requests happen naturally on a duel

I know that the whole point was to make this as automatic as possible, but if we wanted to truly test how long this could go on, perhaps allow the opponent to activate some junk in response to the morphing jar's activation. It does seem to be that the game has said "it has been x amount of minutes since the timer has gone down, so we're kicking you". It's good to test all variables.

I can't exactly remember what caused a what I'm about to tell, but, i remember playing my dragonmaids deck, had ernus in hand against an.. i can't recall man.. I think tri-brigade?. the point is as they were doing their combo i was constantly prompted to activate my ernus i keep just mashing right click to cancel.. i don't know if it was because I was spamming right click, but i was stuck with a prompt of activation of my ernus over a tri-brigade card.. and no matter what i did or where i click the pormpt never went away. right-click cancel active nothing worked and my timer was going down, i obviously surrender and jumped into another match. you know what happen when the loading screen was happening? I had the same prompt to activate ernus, but the tri-brigade card was replace with "Xxxxx-xxxx-xxz effect is active" i was locked once again because this prompt didn't even let me put a card on the field. I had to alt-f4 the game and then it fixed itself. the code may be impressive but it has some fatal bugs. I wish I remember more details but I forgot to save the replay, ups.

New stress test: Is it possible to repeatedly do a hostage situation by activating a negated Zoodiac Whiptail's effect endlessly on a Zoodiac xyz?

You could try to use YGOMaster to try the Pole Position loop

Kinamit probably hired people like Coder to test every possible loop lol

alan turing in shambles

Could be just the timer and the number of activations since the timer has stopped. Clicking on your screen doesn't affect the actual gameplay.

Would it still stop if there's something that gives you effects for every summon/destruction?

you should do Bagooska and the continuous spell that's in Yang Zing

What if you play outstanding dog maron and prohibition on it? Would it go to gy and then back to deck since it can't be summoned because of prohibition. Or not activate at all?

Yo idea what if u did this but to mill a crap ton of spell cards into the grace so u can activate magical explosion trap to inflict 300 damage for each spell in grace so in theory even if only 30 spells are sent that’s still 9k damage for a 1st turn ko

But, does manticore of darkness loop work on MD? I wanna know, because you could deck people if you get Maxx cd

The effect says to shuffle your deck. If I had to take a guess you can not shuffle 1 card, it must be 2 or more cards to shuffle. So I think that is why it didn’t work?

One of the things I notice when you did it with the D hero, the same activation of a card will stop or in this case...cause it to forfit the players control. So as long as another card involve in a chain...it could possibly carry on. I play jar #2 but not in the same phases. XD;;

What if you set 2 jar #2 or 1 jar and a flip monster that gives lp Or jar and magical merchant with the sword Or the jar and a flip that gives lp with the moon mirror so you have to pay and interact with the loop?

Coder can you make a video on must know OCG ruling differences vs TCG cuz Master Duel is based on OCG rulings.

Ruling question: Can an effect that would destroy monsters that have less defense than it be used on link monsters since they have none?

Rip for Dire getting more work

Damn, Konami really prepared for these huh

Whats the official ruling on this loop? Does the trap get destroyed?

The game has determined YOU are the problem.

how about michion timelord?? how many halved points can be????

Hmmm, maybe it would let you do the loop more times, the more different cards there are involved. Like with the primal-seed/Envoy of the beginning loop🤔

Is it possible to do it in the battle phase? I don’t know why but for some reason I think doing it in the battle phase makes it infinite.

Long video had to x2 speed the video , but wow such a great a video

konami really out did them selfs this time

I mean, this is just working correctly, because infinite loops that don't change game state are against the rules, and the loop ends

What happens when D/D/D Rebel King Leonidas/Prime Material Dragon, Metal Flare and Beelze are face up on the field at the same time and a card effect trigger metal flare? EDO does the loop twice before it stops. I wonder how master duel handels this

Is there a way to actually win with this using a burn on summon card?

What about having two passive effects such as "all cards sent to grave are banished" and "all cards that are banished are sent to grave instead" then its a situation where if the card is banished it must go to grave and if it goes to grave then it must be banished so it cannot end. It might actually break the game's logic.

These are amazing. Wow.

We need farfa's game dev viewer to explain this

i knew that like 5 years ago bro lol you can also do the same the same thing with king tiger wangu and treeborn frog ss treeborn tiger destroys etc etc... i was actually shocked they made this card legal I'm like awww they forgot about the kid that won a regionals with a deck like that and got MJ #2 to go from 3 to banned in a single weekend lol!

because of clickbaity title, i straigth gone to the end of the video still unclear.

What’s the trap that he’s using to flip the monster

This is the correct ruling. You can not shuffle 1 card….

can someone tell me what such an ifinite loop would mean for the outcome in an irl duel?

So where is the so called «Ban» ?????

Can you do the gateway of the six to see how much counter it will be max ? :))) love to see that

HOW does DistantCoder not know the rule about returning cards to the deck if you do not have a deck? like pot of avarice, or Satellarknight Sirius, or Disciples DracoPhoenix? I feel validated

Is there any point with testing this loop with a card which advances game state when flipped? Either inflicting damage, or drawing cards.

Well technically speaking you can break any look in programing if you do it smart. Seems Konami did pretty good job thus far but we know players will always will find new ways to break games. God speed to those people!!!

i wonder if your opponent has something like outstanding dog maron in their deck and you also put needle worm in this combo if that loops infinitely or if it also breakes when your opponents cards move or maybe your opponent is the one who times out.

Seems like the game can’t shuffle a card into an empty deck. That seems more like a bug.

I’m curious to know how long the six samurai loop can last?
