Surviving The Deadliest 2-Player Game

- Get an intro to the math of Russian Roulette with "Surviving the Deadliest Game": • Surviving The Deadlies...
We know from “Surviving the Deadliest Game” that there’s no more dangerous game than Russian Roulette. And is there any game stupider than a duel in which two people stand there and shoot at each other? No -- so what happens when you combine them?!
Legendary scientific thinkers Nikola Tesla and Thomas Edison are about to find out as their balloon avatars battle it out for electrical supremacy.
In this scenario, there’s only one single gun that Edison and Tesla pass back and forth for each shot. Can that game actually be fair if someone can go first and win on the first shot? If the first player has a probabilistic advantage, how much is it?
Is it possible for us to adjust the game in such a way that the first player’s advantage is a lot more fair? Can you EVER have a perfectly fair turn-based game when it’s possible for a player to win on the first turn?
Oh, and there’s actually a way that you can use your phone as a random number generator to simulate a Russian Roulette game in a perfectly safe way.
We thought The War of the Currents was over, but it won’t be decided until today. Edison and Tesla will enter Vsauce2. Only one will leave.

People are mentioning using dice as a Russian roulette simulator. DO YOU HAVE DICE IN YOUR POCKET? I DO. BUT DO YOU?
ALWAYS
Maybe
yes most of the time yes.
DND player is always ready to play
I have dice on my desk. Also I wouldn't say this is the deadliest game, for example you could make a game out of everyone drinking cyanide and see who lives the longest.
We interviewed 500 people who had played russian roulette.
All of them survived. Russian Roulette is a completely safe game to play.
Kids, this is why statistics are deceiving sometimes
survivorship bias best bias uwu
@@eclecticsoffy statistics are always deceiving and that was a good example
@@cl759 yeah, not always, but a lot of times
@@eclecticsoffy how so ? I found every single time it can be used to suit the needs, thus always deceiving
My grandpa was so good at Russian roulette that he lost only once
Oh that's why he was soo good
:|
Ok thats a good one
Cool, hows he doing?
@@nicokilg8529 he would respond: he's cool, just visiting the grave for some years
I love the detail of him hesitating whenever shooting Tesla, but absolutely zero for Edison
tesla had a dark side though
The Russian roulette I heard is a different version:
Instead of shooting at their rival the one who goes first shoot his own head instead and then hand the pistol to his rival for his suicidal turn _without re-spin_ and so does the rival will hand it back without spinning the cartage again if he survives.
And there is a trick for this version of roulette: if you goes first and you survived the 5th shot, instead of handing the revolver to your rival for his suicidal turn, do him a favor by shoot him directly because chances are as soon as he loaded the 6th guaranteed shot he will cheat by immediately point the gun at you and fire.
I'd be curious what the statistics were on if one person spun the chamber and the other one didn't
@@RomanNardoneThe person who doesn’t respin the chamber only has a 4/5 chance of surviving an individual trial compared to the one who spins having 5/6.
@@Ippikiryu thanks I appreciate it 🙂 so are your calculations accounting for the nonspinner going first?

If i did the math correctly, it is actually perfectly even
Pro tip: The odds are better if you don't use a revolver.
Use a semi-automatic or fully-automatic instead
@@rjs6510 to be fair that reduces the odds to a nice even 50% coinflip

Fun fact: 5 out of 6 people find Russian Roulette a completely safe game
Nice
Well the 1 that does not find the russian roulette a safe game won't be able to tell us the reason :/

"you can run a russian roulette simulation without a computer program"
*pulls out a computer from his pocket*
*uses a computer program*
...
he said "you can" not that he would
He probably meant "dedicated computer program," or a program meant specifically for that simulation.
He also calls a stopwatch a random number generator, which it definitely is not.
@@maxhuzen6329 I think he's referring to the _viewer_ as the random number generator. It's a little unclear, though.
@@maxhuzen6329 Many "random number generators" are actually just stopwatches. They use time in the same exact way he did in the video (but to a more precise decimal) to determine "random number."
interesting that this is the first time i've heard of spinning the chamber again after handing it over to the next player, usually the first person loads, spins, pulls, and just passes it over, player 2 just pulls the trigger again.
Yeah, I was confused when he suggested that each time one person's round fails, the next person gets one more shot because I thought that eventually it would just reach a point where one person gets all six shots and is guaranteed a victory lol. Spinning it each time does make more sense.
@@WoWhistorian also it is possible to rig if you know what ur doing so it makes sense for the second person to spin as well
There was a flash game like that back in the day. You know, when flash games were still a thing.
@@6272355463637 there are a handful of flash emulator plug-ins still going around, and if you were like me and saved the .swf files, you can still run them with the standalone player
@@ElderonAnalas Didn't know how to do that back then - I was quite new to the internet.
But the game I'm thinking about differed from how this video played out, too. You could choose to spin the drum.
plot twist: he took out the bullet when it was tesla's chance
nah you can see the bullet tho
@@MINECRAFTLOVER4000 r/woooosh
Look at 9:00 how he reaches back to grab the bullet

His wife is the crafty one...
thats not really that hard to do.

Joke
I love how excited he gets when the balloons survive.
That was such an intense scene to watch.
Yeah, that's because he's also a balloon.
same
I absolutely agree ahaha
I think only randomizing once in the beginning, and just firing consecutively afterward, would make it an even 50/50... at that point there's a maximum turn count (6), and parameters for victory (even or odd) which aren't affected by who goes first. Correct me if I'm wrong.

The best proven way to guarantee a win in a Russian Roulette is with another gun in your pocket...
You will have to kill all the players before the game starts...
It's the exact same outcome as you would have won if you played by the rules...
Plus, No one left alive to blame you for cheating...
No a toast to keep the courage is the best way to win Russian Roulette. Good old Pal Polonium...
i can comfirm this works
I mean yeah it works, but my backyard cant fit anymore skeletons... But I have an idea. Massive Death ray. Cart it in and say it's a surprise, and when the game starts, BLAM. No cleanup, my backyard can finally rest.
Can confim, never lost a Match once
3 People can keep a secret, If 2 of them are dead.
Your videos are AMAZING!!
I TRULY WISH YOU ALWAYS LOVE MATH.
He actually forgot to put in the rubber bullet, and he realized his mistake only in the last round
Video's purpose: how to make a game of killing more fair. Bloody brilliant.
Haha, yeah. A pity Headison still had an advantage.
I'd do this that way: Headison spins and shoots. Tesla shoots. Repeat till dead end ;)
It easy to see it's perfectly fair as the chance of bullet after spinning being in the first chamber is the same as in second (if we neglect the off-center mass of the bullet causing slightly uneven spin).
Alternatively it can be: First baloon spins, shoots and passes the gun. In each next step a baloon shoots, spins, shoots again, passes the gun. Also 50 - 50, but both get chance at spinning.
*Bloody* like literally Bloody
It's not a game of killing....it's a game of dying
That "this video was sponsored by no one" was so aggressive lol
"This could have been you here"
This is one of the most entertaining videos I've seen in a long time! Hilarious! Nice work 😅😅😅
You could make the NFL coin flip much closer to even with a simple change... the team that wins the coin flip would still have a 52% chance to win, but if you made it so the team that lost the coin flip only had to tie to win you'd get them up to 48%. It would also create an interesting choice... let the team that wins the coin toss decide to either receive, in which case they have to win to win, or to receive, in which case they would win or tie to win. That could create an interesting tactical decision. A team with a really strong defense might choose to kick with their only goal being to stop the other team from scoring.
Don't know about (american) football, but isn't it much easier to enforce a tie than to score, which is a prerequisite for winning?
Wow, balloon Kevin got the real Thomas Edison and Nikola Tesla. If only real Kevin were here to see this

fun fact about Duels: they were very formally done, and they were made specifically so that odds are, assuming it even got to shooting, neither of them died by having the barrel of the gun be very small, causing the bullet to bounce around in it, and, most duels in the first place never even got to the shooting, people tend to assume that duels were informal, but in reality, there was a whole process, basically, if your pride was challenged, you would challenge the person to a duel, assuming they don't back down, you pick your second, who is there to basically there to just talk to the other second and try and resolve the issue, so the seconds are essentially peacemakers, then you have a doctor on site, turned around, etc etc, like I said, there's a lot of formalities, and few even got to the shooting
Also, a lot of these duels used an "fake bullet" that only made the noise and a little smoke, so they didn't get hurt
Don’t worry, I watched Hamilton.

"without a computer program"
**pulls out a phone**
He kniw that you can just search rng on google and google will give you a random number, right?
@@tntbrine5237 The numbers generated by computers are pseudo-random, they're not actually random.
@@ava_niche the stopwatch method is dependent on humans, I think that computers are more random.
@@janekkouril476 it's opposite. Computers are pseudorandom. Humans are more random than a programmed machine.
@@nikhilpolekar8325 Ask 100 people to choose random numbers from 1-100 and I bet you'll see some reproducible outliers. Ask a class of students to "fake" a series of 50 coinflips and it'll typically look "more random" than a real one, which will often have "patterns" like six heads or tails in a row - a random outcome which humans consider non-random. A person could, probably quite reliably, stop the timer in a designated region of they so wish. Human behavior can be used to generate randomness, but it has to be something we don't directly control.
If you want a result which is unpredictable (by someone who has access to a normal person's resources), computer PRNG will probably do much better than any human choice. Many computers *do* use subconscious human input to seed their randomness. If you have fine enough control to affect that in a predictable way, you could definitely control a dice roll or timer.

Rhapsody in Blue... nice. Such a wonderful song wonderfully in the public domain as of recently. Will probably hear it all over now.
I think the best way to approach the inherent unfair advantage that the player who goes first gets is making the one who went second fire 2 shots, but then every subsequent shot returnes to only 1. This case it's also not the insanity of the survivor getting so much better of a chance at winning because *BOOM,* they get some 69420 shots in one round now!
Why not actually make it even more of a duel: each one gets a gun, both spin and pass it to the other, and both shoot their opponent simultaneously?
That makes both of them losing possible
@@marcelobulhoes6180 though true, it's still a fair duel with Russian Roulette mixed in.
hmmmmmmmm
Certainly one will shoot before the other just to guarantee his life if both guns are loaded.
@@pbnetto not if the shot is automatically timed after the roulette is spun
“You’re not going to believe this. And if you do, I won’t believe you!”
I’m using that
Im way to excited about this duel!
I’m ten seconds into this video and the rhapsody in blue is already giving me ptsd
11:02 You can actually see the dart in the chamber for about two or three frames when he swings the gun around.
Oh yea there was that blue bit
But after he was done with re-spinning the cylinder a few seconds before, the bullet actually ended up 3 frames away from being fired. So, it wasn't truly "random" or honest.
"Anything...more dangerous"

Thank you fantasia 2000 for expanding seven year old me's musical tastes! A classic!
He is WAYYYY too excited for their demise
Hey Kevin, check my math here but I think I can make it completely fair:
If player 2 doesn't spin the cylinder (or can choose to spin the cylinder, but it's best if he doesn't spin), a quick math gave me the chance of player 1 winning to be exactly 50%.
Player 1 still have to spin the cylinder every time, of course.
Man, if you want the most fair game of russian rullet, use a semi-automatic pistol.
If the coin is a fair one, this is a perfect 50/50.
could you imagine the torture of the anticipation of a 6 shot round of roulette?
seeing just how excited kevin gets when a shot misses is the best part
Your reaction every time it missed always made me smile without failure.

If Edison goes first, then Tesla has two shots and then they start taking turns with one shot each, Edison will have 48.2% chance of winning and Tesla - 51.8%
Better yet, just have them do two shots indefinitely after Edison's single shot.
@@theoldfinalchapters8319 Yes, in this case it's 50.8% for Edison and 49.2% for Tesla
Wouldn't it be even better to use the sequence
ETTETEETTEETETTETEETETTEETTETEET
I guess it's called the “fair-share sequence” (that's what I read in another comment)
You can generate it by starting with E and then forever replacing each E by ET and each T by TE
Or you can by putting the same sequence you already have behind it and flipping the E's and T's
@@andermium You can also define this sequence in another, maybe a little more complicated way: take the sequence cscccscscscccscccscccscscscccsc It is defined in the following way: You start with c, then write s and repeat the sequence before it, then write c and repeat the sequence, then write s and repeated it, then write c and repeated it, and so on.
Now you start with E and every time there is c - change the letter, every time there is s - it stays the same.
@@ivanzlatev9298 I've wrote a short script in python to optimize the game - where each round the player less likely to have won so far takes a shot. Edison's turns are represented with 1's, Tesla's with 0's. Got the following sequence:
1001011001100110011001011001100110011001101001100101100110011001...
Turned it to hexa for a more compressed representation:
9666659999a65999a5a6665a659999a659a665a65a5a.
When stopped, the difference between their chances to win is ~1.55e-15 (in Tesla's favour surprisingly), and the chance for a tie is ~9.6e-15).
Obvious patterns are hard to find, though it does start along with ETTE-TEET-TEET
and then breaks out and even presents other viable 4-turn-blocks: 5=TETE, a=ETET
The odds change depending on the amount of available information, so to even it out you remove some information.
Two guns. One bullet/dart. Nobody peeks down the chambers. Guns are swapped between each set of simultaneous shots.
Pico added it more fun adding Rock Paper Scissors mechanics
The Carny music for this is just great
The excitement was contagious
Really was
I never knew you spun the barrel after every shot. I always thought you spun once, then each person shoots without spinning again.
He literally said that in the video. Pay attention :/
@@alanbanh not that deep
I think there are variations, but that version has a problem where after 5 clicks the chance is gone and there’s no reason to continue the game.
@@justins8802 the game is decided after the first spin, no more randomness after that
@@LuLu-ip4zb Sure, but if no one knows the position, then from the perspective of the player, it’s chance all the way until then last pull.
My point is the game changes significantly on the last pull when there is a 100% chance of death.
