Next week Dzeeff be like: Maxx C Wangu Departed Exodia.

Had a guy play galaxy eyes and when he attacked with his negated photon dragon he activated it's effect still and it fizzed, but on res he activated it again and then a 3rd time before the game stopped him from doing it again and proceeded to damage calc. He tried to trap me there cause I negated his stuff but the game was like "nope". I'm actually surprised how much effort was put into this game to stop infinites and hostage situations.

judges on duelingbook: no you can't do that, send pole position to the gy judges on master duel: i am the master of chaos

For folks that are talking about burn loops, it's not an infinite loop because the loop ends when your opponent's LP reaches 0; The Departed/Wanghu loop stops at 10 because it's a loop that does not determine a winner if the loop continues; the reason it stops even with Maxx C activated is because the infinite loop can still continue infinitely even without Maxx C. The burn loops can't continue if the burn component is removed, so it continues until there's no more LP to burn, which causes a win state for one of the players anyway.

Back in like 2015ish when Snatch Steal was still Limited, I was on YGOPro playing Gimmick Puppets. I had a Gimmick Puppet of Strings, and my opponent summoned a Cyber Phoenix. Then, he activated Snatch Steal targeting my Puppet and chaos reigned. My Puppet switched to his side of the field, thus falling under the effect of Phoenix which prevented friendly machine-types from being affected by spell cards. This returned the Puppet to my side, where it was again affected. The Puppet then began to rocket between the two fields at a blistering speed without any sign of stopping. I saved a screen capture but my opponent and I eventually had to close the software - we couldn’t even resign. Clearly, the devs hadn’t accounted for this situation in the slightest.

I'm enjoying this hunt for loops "series" Master Duel seems to be coded in particularly robust ways when it comes to the Dueling gameplay, this one outs at 10 repititions and the last one destroyed one of the cards relevant for the loop

When you can draw more cards with a maxx c challenge, than a freaking infinite loop

Test this loop with Zombie World and a soul absorbing bone tower... it will still be an "infinite" loop, but since there is an actual change to the game state (milling the opponent) it should keep going until the opponent mills out.

Hey coder, could you do a rulings video on master duel? Like how you can monster gate under iblee, or how certain cards interact with one another that are different from tcg? Love the video, keep upt the great content!! :)

I wonder if the game code is programmed to read the cache and if the same effect (Departed's self-summon from GY in this case) appears 10 times, the game simply nullifies the 11th instance. Also I wonder if infinite loops like Jinzo/Amplifier/Skill Drain/Royal Decree are programmed into the code to be explicitly recognised or does the game simply recognise that there is one and pops a pre-programmed choice.

that just goes to show how much effort and thinking went into the creation of this game. I dont say this often but, WELL DONE KONAMI

Questions then: 1. Will this be adapted to the physical card game rulings? 2. Does Master Duel allow 10+ loops that can manually be stopped (like if I had Called by the Grave in hand)? 3. What about infinite loop burns like Red-Eyes Flare Metal Dragon vs Beelze of the Diabolic Dragons? It takes 16 iterations to inflict 8000 damage with Red-Eyes' effect. Does it stop at 5000 damage and give me 1 more move to activate an effect?

I honestly would have preferred the game to check if the gamestate changes in a way that could determine a winner before breaking the loop. If during the loop a win condition would be met, like a player drawing their deck with Maxx C, or someone getting burned for lethal because of a card effect, why not just play it out?

Master Duel really just enters duel chat on a judge call and immediately hits em with the "Have a nice day"

I'm so proud of the ygo master duel devs

In Duel Links if you managed to set up an infinite loop that worked off a optional trigger effect, the prompt would not show up after the 49th successful iteration. I'm interested to see what happens if you set up an infinite loop like this in Master Duel. An easy one is a Maji-Gire Panda loop. (Maji-Gire also gives you an easy way to keep track of the amount of times you have looped.) 1. Get Maji-Gire Panda, Ancient Crimson Ape, and Green Baboon Defender of the Forest on board. 2. Have a second Green Baboon in your graveyard. 3. Your opponent puts Slifer the Sky Dragon on their board. 4. Your opponent activates Wonder Balloons and puts 2+ counters on it. 5. Raigeki break Green Baboon, the other one will trigger, you pay 1k, it summons, gets popped by Slifer, Ancient Ape gives you 1k, Green Baboon triggers. After 49 times, Duel Links will not give you the option to activate Green Baboon. Another infinite loop using ignition effects that I would be interested to see: 1. Activate Acid Downpour and Imperial Iron Wall. 2. Get Maji-Gire Panda and Wanghu on your board. 3. Put Chain Dog in your graveyard (foolish burial or some way to discard it, you can't control anything but 2 beasts.) 4. Activate Chain Dog, he gets popped, Panda gains attack, repeat.

I'm absolutely loving this series of videos!!

yo coder, I rarely commented on your video, but I have to tell you that this kind of content is really good. Keep making it, good job mate!

i don't know if you really want this infinite loop of subbing because after the tenth time the subbing doesn't resolve which ends where you started as unsubed. also i wonder if you could do a turring machine. i think the pieces are there to do it if if you would never be able to do it in ranked but you just need cards responding to this loop but also at some point change what they are doing to make a non determined infinite loop. i don't think someting like that could be detected by any program that isn't specifically searching for that.

I got Manticore looped for like ten minutes once, probably didn't trigger infinite prevention because it isn't mandatory, so the opponent just kept going until they were about to time out.

I was expecting it to declare Wang-hu the problem card and pop it. Interesting.

My face when Master Duel is actually well programmed.

It's so interesting seeing how these interactions work in this game. I think it's kind of good though that Master Duel has a way to stop these loops. I was ready for that Necrovalley interaction though. Gravekeepers are my favorite Archetype. :P

i'm happy that they had the forethought to handle something like this, but not sure if i'm a fan of their way of going about it. it should only end a loop if there is no change in the gamestate. because there are some pretty cool loops that actually facilitate some sort of win condition like the stardust loop in super rejuv exodia, or this with maxx c active. also, it should be able to detect a loop much sooner than 10 reps.

Would be a cool series, Loop Busters

Konami: "Coder will you knock it off, stop trying to break our game-"

I wonder if this also applies to red/blue loop for six samurai. It requires player action, but if they don't allow you to perform the same action more than 10 times in a row, does that prevent you from using the loop?

so magical stone excavation your departed while you have maxx c in hand, summon wanghu, draw for exodia?

More mastermythbusters please I'm loving this series lol

Gotta Hand it to Konami for making this right. GJ

The stalemate detection needs a bit of refining, but good to see it's implementation.

It probably detects when a certain board state is repeated x number of times, like the draw condition in chess

Ah you guys dont know the shudderwok incident from heartstone? Hahahahaha

The reason for the last test is negation of effect in gy in the ocg of negated will not be able to activate again. This i believe is the upperdeck ruling as well.

Konami took the time to program a cap on infinite loops but cant prevent your opponent from knowing if you have a hand trap like max c

What would be better with this loop? Red eyes burn or Exodia?

Someone did this with Samsara Lotus and it kept summoning under Maxx C until a deck-out happened.

Sorry Coder. I tried to infinite loop my sub but KZfaq stopped me after 10.

I wonder if the game is programmed to look at the actions being done, like in the log, and if it picks up the same pattern being done more than 10 times with no player input, it just negates that effect or something. So no matter how long the string is, if it’s the same pattern, Master Duel will pick up on it.

Loops that can be done manually like Six Samurai with the Gate and Shogun keep generating infinite counters can still be used normally because it's the player who has to manually perform the actions and is up to them to stop.

It's a good thing that cards of safe return is never coming back.

I can understand Master Duel preventing infinite loops that don't experience a change in game state. But what about loops that do result in changes in game states, kind of like Flare Metal burn loops?

I'll definitely try to point out this one when I do that survey the game keeps asking me to take if it's possible. As that clearly is effecting the outcome of a game with drawing cards.

Welp, I obeyed the sub for the infinite loop, and clicked the subscribe button 10 times.

I don't know if Konami did it on purpose, but Sangan litteraly FLOATS after the dice roll.

In theory you time out a treeborn frog sp loop if you negate it 10 times with a beefed up a Light and Darkness Dragon.

Once to "punished" a Rhongo I tried to activate 70+ times a Danger that was Called by. Every activation stopped the timer and reset it from the start of the second, making possible to do 2 activations per second. Basically I stalled the timer for 25+ minutes on my first turn going second. This means that if the action is manually performed, despite being constantly the same, it can actually go on more than the 11 "auto-loopped"

There is an exception for manually triggered infinite loops like what can be done with rainbow life to farm infinite lp

Glad i saw this, i was gonna try to build the all out attack mj2 deck but if its gonna jus stop the loop after 10, its too risky to bother building.

the first one is as simple as, "how many times you want to summon this monster?". wonder if this should be the response to loops by the ai, instead of simply "fizzling" the problem card.

King Tiger Wang Hu+Dna Surgery+Soul Absorbing Bone Tower+Destiny Hero Departed+Maxx C

Like a yugioh themed Mythbusters. "Deckbusters"

Shit, Master Duel was made well? hot damn

Slifer/ wangu+ departed +someway to burn lol

And this turns into an ftk some how

Now you can start a myth buster series lmao

Props to the master duel coders good work.

This sucks for certain interactions like Red eyes flare metal and beelze king of dark dragons or something. Flare metal burns for 500 beelze gains 500, flare burns, etc

Since it didn't treat Maxx "C" as changing the situation, does that mean you can't tech 2 copies of Manticore of Darkness as an anti-Maxx "C" measure?

Infinite Loop should declare immediate draw

Fun fact this also works with samsara lotus

Departed only activating once under Necrovalley is correct, right? It's a trigger effect that checks the current phase, and those are always Once Per Turn. Departed loops if it leaves the GY because that once per turn resets, but since under Necrovalley it's staying in the GY, it's the same copy and can only trigger once.

Can we get the Gellenduo Beelze Flare Metal FTK for that Loop? You know "Take Damage and Beelze activates to get a boost, that triggers Flare Metal damaging for 500, triggering the negated Gellenduo which would get destroyed if you take Damage but since Gellen is negated it isn't destroyed but Flare triggers again because of it etc

This is interesting because the catbat/lotus loop still works perfectly fine, though this is because of the effect damage stipulation I guess?

Six Samurais also have an infinite loop with their two level 3s, Gateway and any other Token card

Duel Links does the same thing, but instead of Wanghu it was having a face-up Remove Brainwashing while the Departed's owner has a full board. The Departed would be summoned, Remove Brainwashing would attempt to return it to its owner, but since there are no open zones on the owner's field, it's sent to GY instead. The loop only happens 10 times before it gives up. BUT does the Departed loop STILL cap to 10 times if it advances the game state? DNA Surgery and Cyber Summon Blaster would burn the opponent for 300 each time Departed hits the field, so it should be able to be used until you win the game. The difference being that Cyber Summon Blaster actually starts a chain unlike Maxx C draws

So why doesn’t tiger get destroyed unlike the jinzo one where skill drain gets destroyed? It says in the policy docs that if a loop occurs after one cycle the loop is stopped with whatever is the problem card going to grave. The only reason I can think this is different is because tiger and the d-hero activate. Edit: But even then the policy docs also state that infinity loops are primarily caused by mandatory triggers, which both of these are.

its coded to technilcy cap at 16 (chain link limit for the game)

Told ya Master Duel is too smart for ya.

Okay let’s see what other infinite loops this game can do

Goddamn, well done Konami. Putting an infinite loop check in there to make sure you don't get stuck in an infinite loop is quite clever.

Didn't this play get officially ruled by either Konami or UpperDeck that Wanghu and Departed go through the loop one single time, unless a mechanic through which a game ending result will occur (deckout, for instance, or burn)? I could be wrong, but im fairly certain.

Yu-Gi-Oh ruling in TCG, any player cannot play a card if it causes a infinite loop it is not allowed. There is a pole position combo where your opponent cannot activate a card because it causes a infinite loop

Gaia has an animation and Dante does not... that is sad AF

So no loops? *breaks phone

... the loop fizzles

Now we need a card that burns for specialsummons

Iv learned about these from Duel Logs

12:07 isn't that common for any cards in the GY to be negated automatically and prevents the loop process due to necrovalley's effect that would attempt to move out any cards from the GY? I only know that any effects in the GY is allowed even the necrovalley is in the field but depends whether the effects of any card would move or not (well the effect would be negated if the card would attempt to move outside from the GY).

I think if i remember right an infinite loop is not legal unless it advances the game state like dealing damage other wise the problem card is destroyed and considered neagted like the jinzo infinte loop

What about an optional effect that trigger when a monster is summoned or destroy, will it still work only 10 times?!

Uhh that’s weird I thought loops that don’t change the game state are destroyed due to game mechanics is there something unique with this loop that doesn’t cause this to happen without maxx c being activated ?

Next question because coder does iblee lock. Can departed resolve under iblee lock because iblee prevents special summons of no links while she's on field

now you just have to get a Psyframe lord omega in the grave under necro and see if you can keep activating it to see if you can just do it over and over for the 400 seconds just to annoy the opponent or if it makes you stop trying at 10 since its optional

Would that mean that one combo with Red Eyes Flare Metal Dragon and Beelze would stop at one point ?

What would've happened with Departed in Grave, Necrovalley on field and chaining MST after Departed being negated. Would it activate again then? 🤔

This is already better programmed than Arena

Back to the Jinzo loop. Does the Skill Drain die every time or does it randomly destroy one of the cards?

is it me or do i keep hearing infinite loopa

So with necrovalley, the mandatory effect is negated and after that it don't activate anymore? Try Doomcaliber Knight with Departed.

Ah, good old Wanghu

You should try to test the infinite burn loop with flare metal and beelze or similar card. Maybe try to increase one players life to see if it will continue to loop to kill them

Basically we traded Bo3 for a game that busts loops. Almost a fair trade. But kudos to Konami for having at least taken the loops into consideration while programming MD.

What if you perform this exact same loop, but one of you has Chain Energy on field? It'd take 16 iterations to burn all your LP

Im curious if the loobbusting mechanism would change at all with zone placement turned on

Guess that makes it a tenfinite loop.

Well Master Duel is well coded

No loops for you! Come back one year.

10:26 - Apparently Departed suffers from 3 stooges syndrome.

what if it activated. got negated then youd mst necrovalley, would departed activate again
