The ending here has a new meaning. Since the "safe " room by the entrance was clean, it became contaminated when you entered and then returned. The last room was also contaminated, the door leading to the exit. Since you escaped.... you let some of the virus out when you left. The virus is out.... and it's in the world... and you, Mr. Traveling Salesman, are carrying it wherever you go. You should have just just flipped the switch and let yourself be buried in concrete. Now the virus won't get out, because you're contaminated. Your suit is, and you can't get out of it. It's a one way trip in realistic terms.
Add in the fact that its airborn, and it becomes twice as bad. You dont even have to talk to someone to spread it, you can walk near them and the have a chance of getting it.

I only ever decide to try and solve these riddles exclusively past 3 am, and never have I felt more proud to finally have solved a riddle that is maybe the 50th trial I've had so far with these videos
Indeed, the way I see it, when people use the expression “aged like milk”, it’s the exact opposite of saying “aged like fine wine”, because unlike wine, milk is something that always ages poorly.
Then the toxic chemicals will travel in the blast if you're talking about explosives, however, if it is the solidish liquid that they showed in the video, it'll work great if it's near the exit.
Bluє Príncєѕѕ •. It's not the virus, it's the riddle. If there was an easy way, there would be no riddle => there would be no fun. So, that button is out of my picture😊
@@trickytreyperfected1482 you missed the point. It can't be true. The first part of the statement states that the virus was made in a chinese lab. The second part says that the virus isn't real. If the second part is true, then the first is false, because it assumes the virus isn't real and thus, it wasn't made in the first place. The statement requires both parts to be true at the same time which is impossible, so, the statement is false.
Suhas Gondi I did this riddle once and Succeeded but now I forgot how I did it so now I came back after a long time and I tried once again but I failed lmao
They got Riddle makers to design the building instead of architects with experiance in biological containment construction. Probably why the virus got out
That answer is wrong. Here is the correct way: Step 1: Don't go into contaminated rooms. Cut the power from the backup systems so the vents don't open instead. Step 2: Call the superiors. Step 3: Little bit of panic, be yelled at by the boss. Step 4: Get lots of help (both nationally and internationally) to aid in the cleanup. Step 5: Slowly decontaminate each room 1 by 1. Don't worry about how long it takes. Days, months, years... Doesn't matter, must make sure everything gets sterilized. Step 6: Finally, walk through the now decontaminated exit. Step 7: Invest in a better designed lab and adhere to stricter protocols for storing hazardous materials. Congratulate! World is Save! You Winner!
1. Pass by the 1st room and destroy it. 2. Pass by all the other room in the way to the exit without destroying it, so ya don't need to pass by ALL of the rooms. 3. When u reach the last one, destroy it and get out of the lab. 4. Congrats! You've blocked the entrance and the exit, so nobody else can enter the lab and the virus can't get out, just leave it there, nobody else will get contaminated, so u don't have to worry 'bout it anymore 😉👍

Osama Jweihan - Computer scientist here. In fact, if you proved that the Hamiltonian path problem could be solved in polynomial time (i.e. faster than trying every possible combination), you would simultaneously prove that EVERY problem categorized as NP-complete can also be solved in polynomial time. Similarly, proving that it cannot be solved in polynomial time simultaneously proves that all other NP-complete problems cannot be solved in polynomial time. Solving this problem pretty much translates to instant fame btw, as it has eluded computer scientists for quite a while now. The current concensus is that all NP problems cannot be solved in polynomial time since otherwise we would have found an efficient algorithm for at least one of these problems, but such an argument is not a very rigorious proof, and it's still technically possible that humans have just been too dumb to find an efficient algorithm yet.
You go to the room just to the right of the entrance, flip the switch, and then go back. Then, you go down 3 rooms, right 2 rooms, up 1, left 1, up 1, right 1, up 1, right 1, and down 3 to the exit.
@@CaptFrost-ed8ij ohhh, i think he thought of a new puzzle! How would you make it so you destroy the contamination, while also leaving the building, and having destroyed all of the contamination without it being spread to your previous rooms with you and to avoid it from leaving the building as well
Hey, I just realized. By this very same logic, you can actually Start and End in the Same Room. Why? Well, first of all, remember the solution. You can go back to the first room immediately after destroying the second room you enter. That also means that you can go through the entire facility and return to the very room you Started in as the last place you go. Mind you, the logic puzzle REQUIRES you (for some reason) to end on the opposite corner, but still.
@Snowmon89 I'm sorry to tell you that your idea fails twice ! -Firstly, you don't have time to come back to the first room every time ! 1:14 1:22 you can see how the instant concrete takes just a few seconds to completely fill the room! - Secondly, let's say you are starting in room a5 (1st column, 5th row from the bottom) After you pull the lever in room b5, you can safely return in room a5, but after you pull the lever in room a4 , you CANNOT come back to the starting room. If you did that, you would be STUCK ! 😂 (And also, you would break the rule "Once you enter a contaminated room, you must pull the switch" ! The first room is not immune to the virus, so it would become contaminated as soon as you move from room b5 to a5) =)
@@francescof3267 Well, no. You are in fact wrong. If you go from A1, all the way down to A4, flicking the leavers in 2 and 3, you can still path back up to the starting room with only overlapping the starting room. So their statement is true that the only thing preventing it is the end room requirements. You seem to be stuck that you have to loop back to the starting room every flip, instead of leaving the double-back till the end.
Nice riddle but there is a problem: When you go back inside the entrance room a second time, you pull the switch to blowup the room because it is contaminated now. But by that same logic, the exit room will be contaminated also. So when you open the door to leave, you release the virus outside.
@@emeraldofdoom3188 okay, but by that logic, the safe room wouldn't be contaminated after you enter the room a second time. but it is, because the airlock system is heavily flawed. seriously, the world would still be doomed even if there was only ONE room contaminated
@@spoonythegamer21 The traveling salesman problem is also a NP-hard problem. With a list of cities and the distances between each pair of cities, you need to find the shortest possible route (while visiting each city and returning to the city you started at).
@internet person then remember all the room except the 1 room is contaminated if you leave the exit it will spread The virus anyway without decontamination room. you remember if you back track back to the first clean room After pulling the lever. it still contaminated the room on the right and have to pull the lever the first room to move down a room.
This is easy! Just enter a room from the entrance, doesn't matter if it's east or south. After you pull the switch, go back to the entrance. And then it's just simple from there. But once you exit out of the last room, wouldn't the disease be free?
here's how it works. You go east/south, open the airlock, and quickly destroy the room. Go back and quickly destroy the entrance. And a decontamination room at the exit to get rid of the virus on your suit.
Panda you are right! It didn't even come to my mind to doubt the question, but after you destroy all but last room, you have to open the doors to outside world. And so leaving rom the infected room, enables the airborne virus to leave as well. So the only way is to sacrifice yourself in the last room.
The reason why the entrance room got contaminated is because the air lock was opened for too long but from the exit it is opened once so there is no contaminating the environment
If the exit room has a negative pressure (like modern operating rooms), then when you open the door for a short period of time, air is sucked into the room and the virus does not really get out. Minus the ones on your clothes of course.
Got this one immediately as I right away saw that you don't have to exit in the same direction you went in so just go back to the beginning again to get into a '1 ahead' sort of principle.
Yes it does. This is a terrible riddle. To make matters worse, the video itself ACKNOWLEDGES that opening a door immediately infects adjacent rooms. It’s just sad.
You should destroy entrance room after airlock opening (04:20). If opening a door contaminate the room, wouldn't it apply to the part of the building after the "exit" door?
Killigram Gamer You realize how you'd have to implement that onto trillions of cells at a time. If you're referring to CRISPER we still have a long way to go.
0: 17 - midnight snacks ( Oreos ) 1:29 - bottom left-hand drawing is called PANIC... look at the others too. 0:36 and 1:12 its on lockdown yet the vents open. poor security. I have a thing for details.
I had another idea. The chatacter could open all doors. When he reaches the last room, he may pull the switch to destroy it. So it means that he destroys every room from the end of lab. And as he reached the first room, he pulls the switch and as the timer starts he quickly exits this first room.
you can also just loop back to the entrance and exit through there, it is functionally equivalent as the exit itself has been contaminated. In fact it may even be safer.
I got it, yayyyyyyyy, Helps to backtrack and understand the symmetry and the implied sub-rules. The main one being that you have to enter every corner, and to do so you have to start at the square closer to the origin and exit from the next. Doing this made it pretty easy to tell that its impossible to visit every square once and the twist had to be somewhere in the rules. Re-reading them made it obvious that the first one is the key to all of this
If the first room is contaminated by you opening the door (you must pull the switch the second time through) you cannot leave the building. The exit room is contaminated so opening the exit exposes the outside to the virus. The only way to stop the spread is to pull the switch in each room and not open the doors out of the building.
yes, unless there is some sort of decontamination vestibule outside the entrance and exit holes, the virus would come out on the person's suit and when they take off the helmet , they would die
this was one of the easy ones for me, unlike other riddles you've posted. it all comes down to what your brain is better at, patterns, mathematical solving etc.
I initially thought of heading directly out the entry for the exit and going around the grid like that. I think it works lol. That's what I get for doing a bunch of these riddles and thinking "too laterally"
bousio it doesn't work like that. 1. You suffocate and die. 2. By opening the doors u let the virus out. 3. Your suit would be contaminated with the virus so u wouldn't be able to leave which means u will suffocate.
+Pathogenic Cyanide Piggy Eyyy finally someone else who plays this game!!! I've gotten through a hell ton of packs and perfected them all, but I'm stuck on Extreme Pack 12x12 level 16. So damn hard!
What about the time period between pulling the switch in the final room, and the exit door being opened before the room is cemented off? All that shit's gonna come out! LOGIC BUSTED!
1:13 you enter the room and there are switches on both sides leading to both doors. They are both 'up' or not activated. 1:17 the door on the right opens and you exit without either switch going down. The switches are pulled by someone/something once you've already exited and the door on the right is almost closed. Presumably both switches are connected so go down at the same time. Where/when do you do whatever it is that pulls the switches down?
You walk through the door. He said "you can't walk out of the room without causing the self-destruct sequence" so if you exit the room the switch gets pulled
When you fail to solve the riddle and 2 years later the virus escapes

After you pull the lever in room b5, you can safely return in room a5, but after you pull the lever in room a4 , you CANNOT come back to the starting room. If you did that, you would be STUCK ! 😂
(And also, you would break the rule "Once you enter a contaminated room, you must pull the switch" ! The first room is not immune to the virus, so it would become contaminated as soon as you move from room b5 to a5)
=)
@@francescof3267 Well, no. You are in fact wrong. If you go from A1, all the way down to A4, flicking the leavers in 2 and 3, you can still path back up to the starting room with only overlapping the starting room. So their statement is true that the only thing preventing it is the end room requirements. You seem to be stuck that you have to loop back to the starting room every flip, instead of leaving the double-back till the end.
I believe he was saying that the first room sealed behind you so you could not escape or something like that.
it was pretty easy. unlike other puzzle I have seen and failed to solve on this channel!!
Nice riddle but there is a problem:
When you go back inside the entrance room a second time, you pull the switch to blowup the room because it is contaminated now. But by that same logic, the exit room will be contaminated also. So when you open the door to leave, you release the virus outside.
You must sacrifice yourself for the greater good.
thats how coronavirus got out
It has an airlock
@@emeraldofdoom3188 okay, but by that logic, the safe room wouldn't be contaminated after you enter the room a second time. but it is, because the airlock system is heavily flawed. seriously, the world would still be doomed even if there was only ONE room contaminated

@internet person I agree, that is a horrible design!
@internet person then remember all the room except the 1 room is contaminated if you leave the exit it will spread The virus anyway without decontamination room. you remember if you back track back to the first clean room After pulling the lever. it still contaminated the room on the right and have to pull the lever the first room to move down a room.
This is easy! Just enter a room from the entrance, doesn't matter if it's east or south. After you pull the switch, go back to the entrance. And then it's just simple from there. But once you exit out of the last room, wouldn't the disease be free?
here's how it works.
You go east/south, open the airlock, and quickly destroy the room. Go back and quickly destroy the entrance. And a decontamination room at the exit to get rid of the virus on your suit.
U cant go back through the entrance because u just filled the room behind u with concrete...think about it.
Critical Mass YOU did not think about it, based on your logic, once the switch is activated, you can't even exit the room and you'll be killed.
Panda lol EASIEST ted ed riddle
Panda you are right! It didn't even come to my mind to doubt the question, but after you destroy all but last room, you have to open the doors to outside world. And so leaving rom the infected room, enables the airborne virus to leave as well. So the only way is to sacrifice yourself in the last room.
1:55 My first instinct would be to give up
I wouldn't consider myself a hero and probably would have called 911 and get a helicopter rescue or something instead of trying to figure it out.
Carolina Lopez lol same 😂 But your in the artic how the heck will 911 get there in the first place?
Carolina Lopez The vents would have released it before they came, most likely, or before they can think of a solution too.
_you are 911_
Do you really think 911 will know how to contain a disease?
Carolina Lopez no call the CDC
Wouldn't exiting the last room spread the virus regardless? There's no way to survive here without letting the virus free
I think you are right!!
airlocks. They are wonderous
The airlock won't help if the air gets contaminated when the lock is open.
The reason why the entrance room got contaminated is because the air lock was opened for too long but from the exit it is opened once so there is no contaminating the environment
If the exit room has a negative pressure (like modern operating rooms), then when you open the door for a short period of time, air is sucked into the room and the virus does not really get out. Minus the ones on your clothes of course.
them giving this really hard puzzle:

Got this one immediately as I right away saw that you don't have to exit in the same direction you went in so just go back to the beginning again to get into a '1 ahead' sort of principle.
What happens once you open the exit? Won’t the virus get out?
And thus the events of *Plague Inc.* Begins.
Yes it does. This is a terrible riddle. To make matters worse, the video itself ACKNOWLEDGES that opening a door immediately infects adjacent rooms.
It’s just sad.

You should destroy entrance room after airlock opening (04:20). If opening a door contaminate the room, wouldn't it apply to the part of the building after the "exit" door?

DarkElf22 same , this is one of the only ones I was able to solve easily
0: 17 - midnight snacks ( Oreos )
1:29 - bottom left-hand drawing is called PANIC... look at the others too.
0:36 and 1:12 its on lockdown yet the vents open. poor security.
I have a thing for details.
I had another idea. The chatacter could open all doors. When he reaches the last room, he may pull the switch to destroy it. So it means that he destroys every room from the end of lab. And as he reached the first room, he pulls the switch and as the timer starts he quickly exits this first room.
1:42 you missed rule 3: you must pull the switch before you can leave a contaminated room
I already knew this was gonna be hard if the Chinese couldn’t solve it

2:It can't leave

LOL true
you can also just loop back to the entrance and exit through there, it is functionally equivalent as the exit itself has been contaminated. In fact it may even be safer.
I got it, yayyyyyyyy, Helps to backtrack and understand the symmetry and the implied sub-rules. The main one being that you have to enter every corner, and to do so you have to start at the square closer to the origin and exit from the next. Doing this made it pretty easy to tell that its impossible to visit every square once and the twist had to be somewhere in the rules. Re-reading them made it obvious that the first one is the key to all of this

Cool Riddle
the brige on was eseyer
Also a possible solution: sacrificing yourself so you’re not leaving through the exit
If the first room is contaminated by you opening the door (you must pull the switch the second time through) you cannot leave the building.
The exit room is contaminated so opening the exit exposes the outside to the virus.
The only way to stop the spread is to pull the switch in each room and not open the doors out of the building.
You're making assumptions about how the virus is transmitted
‘Unless you can destroy it the vents will open and unleash a deadly plaque, you get your hazmat suit and get ready to save the world’

these types of riddles give me so much anxiety but i cant stop watching
Alright who failed
Solution: you ask Kim jong un to destruct every room with his nukes
a virus can suvive a nuclear attack
Stephen Cranmer he turned on self destruct how can’t a nuke do more
What a hilarious profile pov
In nuke have more viruses lol
That would release the virus... nukes don't destroy every atom
Wouldn't the virus escape when you exit the last room?
Because the last room was contaminated and that switches room was already pulled off before she departed the contaminated area
no ____________
Sophia Kratochvil l
@Sophia Kratochvil it can float and move around
yes, unless there is some sort of decontamination vestibule outside the entrance and exit holes, the virus would come out on the person's suit and when they take off the helmet , they would die
this was one of the easy ones for me, unlike other riddles you've posted. it all comes down to what your brain is better at, patterns, mathematical solving etc.
I initially thought of heading directly out the entry for the exit and going around the grid like that. I think it works lol. That's what I get for doing a bunch of these riddles and thinking "too laterally"
Or turn off the ventilation system
bousio ikr
bousio it doesn't work like that. 1. You suffocate and die. 2. By opening the doors u let the virus out. 3. Your suit would be contaminated with the virus so u wouldn't be able to leave which means u will suffocate.
Ethan Ferns better you than the rest of the world
Ethan Ferns Your suit would be contaminated even with this solution though
isn't your suit designed to not be contaminated ? otherwise, wouldn't you die no matter what you do ?

It’s a HAZMAT suit you dumba*s
@@darkicedmlfan6300 yea that suit Only protects the person inside, but the people around will get infected.
I know this lab is already terribly designed, but do you really think they don't have a room at the exit for decontaminating personnel?
Kermit The Memefrog Want Sum Lipton Tea with honey dude legit nobody is in the lab except you. I don’t know this, anyway, and I could be wrong.
1:13 you enter the room and there are switches on both sides leading to both doors. They are both 'up' or not activated. 1:17 the door on the right opens and you exit without either switch going down. The switches are pulled by someone/something once you've already exited and the door on the right is almost closed. Presumably both switches are connected so go down at the same time. Where/when do you do whatever it is that pulls the switches down?
You walk through the door. He said "you can't walk out of the room without causing the self-destruct sequence" so if you exit the room the switch gets pulled
Me: *Fails Miserably*
*A few years later*
Me: OH NO ITS ESCAPED AHHH!!!
