For a 17+ mandatory chain, a good option is firing off a Dark Hole while the field is packed by copies of Babycerasaurus, Petiteranodon, Black Pendant and Moon Mirror Shield.

[@justagamer878]

For simultaneous mandatory effects, try with Aromages, both of you with 6 Monsters each

[@goldencalf13]

Plus the spell/traps also occasionally get an effect when gaining lp

[@alfiearmadillo]

Or just 3 dark room of nightmare, then use 2 or 3 burn effects in chain

[@MiguelitoJimz]

3 Dark Room of Nightmare with Face-Up Light Stage and 3 Lycoris on field should do it

[@lennartstockl5826]

Does the dark room chain itself tho? I don't think it expands the chain. It will only flash up shortly at every resolved burn iirc.

[@alfiearmadillo]

@@lennartstockl5826 it does yeah.

[@rsjeyzer]

I think it only goes to 16 beacause there are only 4 bits assigned to count the number of chains. Starting from 0000 = 0 in binary notation and ending in 1111 = 15. Since there is no more space or to not waste more memory it just end there.

[@yugiohmania827]

This is the most probable answer as to why it is that way. I'd love to know just how they managed to implement all of this logic into the game though. For the most part, it's pretty amazing just how many different interactions they got to work right.

[@darkenblade986]

smallest addressable memory is 8 bit also known as a char which goes 0-255. I am not saying you are wrong just that it is very strange to be bit masking a char for chain count.

[@salkohajric9641]

Good idea but I dont think they bothered with memory. Most likely they simply implemented very simple ways to stop loops. Like if same actions occure 10 times stop it because it seems too much. If chain happens more than 15 times somethings is bad so just stop it, 10 probably seemed too low and 20 too much.

[@fidelluz2942]

@@darkenblade986 master duel probably use 4 bits to address the chain links. Each CL not only contains it number but also which card and which effect are being activated. My guess is that after addressing the possible cards and the possible effects the devs are left with 4 bits or half a byte to order the CLs. Again it's just my guess but it's probable that it was done to salve space

[@darkenblade986]

@@fidelluz2942 interesting take. Though this may be happening this implementation would not save space as a mapping would need to be created from the 4 bit id back to the actual card it is referring it. This imo would be needlessly complicated with very little benefit as this is running on modern hardware and not an embedded micro controller. I think it is much more likely that some validation of sorts determined that the same card chaining to itself must be a loop and terminated it.

[@KuroeNezumi]

As other have been saying, most likely it is a hard restriction for memory reasons (both having a maximum amount of chain links, and that the maximum is that "''"low""") that, if it also works on mandatory effects, should prevent infinite chains from happening.

[@Kurumisama]

honestly, sounds more like an arbitrary limit, like there's no way it needs to keep track of chains in a 4bit integer on the other hand, there's no circunstancie in which this would happen under normal gameplay aside illegal moves that cause an infinite loop.

[@malikatkinson1647]

“Zeus! Chain link ____!” Has the same energy as “Draw! Monster Cardo!” Nice job

[@TheArcher143]

For the Mandatory Effects, just play triple Grass with 57 cards that trigger when sent to the graveyard.

[@john1691]

Most of them are optional though, like Paleos. I'm pretty sure there isn't 57 wulf like effects in the game

[@astercat49]

To be fair, I have never seen anything past chain link 10 in an actual match. I've only seen people go higher than that when they were specifically trying to.

[@Diuan]

if you want a really long chain of mandatory effects you can use magical merchant with sylvans and other cards with mandatory effects that trigger if they are sent to the gy

[@TheGoldenRater]

sylvans aren't mandatory except tree and miko even then all the SS are hopt. I can only ever get to chl 5 :(

[@Diuan]

@@TheGoldenRater Well, there are sylvans with mandatory effects as you noticed. It was just an example off the top of my head. Other ones can be Snapdragon, Wulf Lightsworn Beast, Skull-Mark Ladybug etc.

[@TheGoldenRater]

@Diuan Oh it could totally work. Merchant is wild. They would probably want that spell that places itself to the bottom of the deck (forgot the name?). Sylvans would be an easy 6. Snap is another 3. Wulf is upto 12. Lady is 3. I'm sure there's more too. I'm not sure how many tries it would actually take tho. edit: Just remembered flowerbot is also mandatory! That's 18 if you can stack the spell and draw merchant early.

[@bluestorm749]

Ngl all those chains look very satisfying on the Zeus

[@esrohm6460]

from the way infinite triggers of mandatory effects work i don't think that it would even put a 17th mandatory trigger on the stack. i would assume that its just hard coded to say under x circumstances prevent anything from happening.

[@stallschula5431]

This wouldn't be an infinite chain link as it would eventually lose all materials.

[@TempestaDominus]

To be fair, 17 chain is a bit much anyway. Not to say it's not possible but very improbable barring few exceptions.

[@AngelofDeath333]

There is a infinite loop you could make with just a few cards and Handsize limit. All you need is Dark World Grimoire and Wicked Worm Beast. Worm beast returns to hand mandatory during the end phase and Grimoire SS a monster sent to grave cause of hand size limit and so you then have discard a card, cause worm beat will return to field and then hand and the circle repeats.

[@hirukashiro5995]

The player would lose due to time limit since the player need to choose which card to discard for handsize limit, or the game will stop it after 10 iterations similar to other tests

[@AngelofDeath333]

Coder you should try some of the random stuff master duel does with mischief of the time goddess. Like for example if you have emptiness face up and you use mischief, the turn skips but emptiness stays up

[@credorn4590]

If you want to know a good way to make chains, use f.a.’s. If you have full monster zones you can get chain7/8 off of one spell, so the. If you and your opponent both run f.a. And both of you chain 5 quick play spells, it all adds up. I tried this with a friend in duel links and the chain reset at 16. If it added Ali’s added together it would have reached about. 36

[@lordoftheearth1]

for 17 mandatry effects just have a 60 card deck with 3 grass 3 left arm, and a bunch of GY effects and have the opponent use chiken game to get a small deck and then mill like 50 with grass

[@brobie_one_kenobi]

What about magical merchant chain strike where you run 34 different monsters with grave effects (BA, Sylvan, Marron, etc) and 3 merchant 3 chain strike (ban list assumed)

[@Yuto_Ygopro]

Funny that the way this is programmed should be through a data structure called a "stack", whre the first chain to go in is the last to go out and be processed, so I assume the "stack" size in the source code is limited to 15 spots(since we count at 0) which is just a dead ass random number that people use like 3 5 and 10

[@carpedm9846]

Its not a random number, its based on binary. In programming, every data is stored as 1 or 0, and "16" is the amount you can count with 4 bits. Starting from 0000 as 0 and 1111 as 15. Probably devs thought that appointing any more bits would be a waste of space.

[@matt_the_penguin]

The stack size is still 16 even if you start counting at zero. 16 is chosen presumably because it's the lowest power of 2 that is reasonably expected to be the length of a single chain. In general powers of 2 are chosen because at the end of the day anything a computer does is in binary.

I wonder if the 16 chain link rule only applies when they are only from the same card like in the video. I mean, what if you used something like Grass and milled 16+ monsters that would trigger in the GY?

[@andrewtat6313]

You could test mandatory quick effects by using the same zeus setup while having doomcaliber knight and mask of restrict on field, to prevent the knight from tributing itself, then on cl15 emergency provisions your mask of restrict. On the next zeus activation you SHOULD be forced to activate doomcaliber knight’s mandatory quick effect.

[@harrisonsharpe8884]

There’s a video on KZbin that shows if you fuse like 100 or more cards into a single monster the game breaks and you instantly lose.

[@balistikscaarz1959]

Because the discard for hand size limit is at a point PAST the end phase technically. No cards or effects can be activated at this little invisible point but since the Graff met it's activation conditions upon being sent that's why it had the option to trigger but not Cir. You basically just aren't allowed to do anything important past this point, even if you summoned scarm off the Graff you shouldn't be able to activate it's effect because you're actually past the end phase.

[@lennartstockl5826]

Grass into a bunsh of manadatory effects looks kinda nice.

[@Balila_balbal_loki]

One person runs a bunch of monsters which are all mandatory gy effects that are not once per turn. The other person uses redoer and perpetua to each opponent's deck. Link off redoer and perpetua to break the game or see if only you can get chain link 16.

[@deltaray3012]

I've noticed a lot of instances where I can't choose the order in which certain effects activate or resolve. And I'm not talking about ordering a chain. 2 examples: I have a Michion and Metaion on the field, both having attacked this battle phase. Normally, if I end my Battle Phase, I can choose to activate Michion first, then have Metaion activate to bounce all the other monsters o the field. But in Master Duel, Metaion will always activate first no matter what I do. Another example is with something like Exodia Incarnate and the End Phase effect of Into the Void. Incarnate adds a Forbidden One piece from the grave to my hand and Into the Void will have me discard during the end phase. Normally, I should be able to choose to resolve Into the Void's discard effect before Exodia Incarnate's effect to add, but Incarnate will always add the card before I'm forced to discard. It can get really annoying and I don't understand why Konami keeps programming their games like this as it's even done this in Legacy of a Duelist.

[@admontblanc]

Could be a bug or it could be because the type of effect determines whether you can order the effects or not. SEGOC usually works for effects of the same type, so if same type effects aren't being allowed to be ordered when simultaneously resolving it would be a bug. You should definitely use the game's ticket system to notify them in any case, if it's a bug they'll likely fix it when possible.

@@hirukashiro5995 That's what I thought at first and would make sense, but haven't been able to find what would be the effect in question preventing it.

I'll just need to do stress testing in solo duel I guess.
