Vsauce — Kevin here, with a game you can

always win. Grab a friend and take turns counting using

numbers from 1 to 10. The first person to get to 100 wins. Which can always be you. To demonstrate, let’s have a friendly game

between me and uhhh… I guess.. I’ll just play with myself. Hey me! It’s good to see me. Am I ready to play? Yes. Yes I am. Okay, add numbers between 1 and 10 and the

person who gets to 100 first wins. I’ll write the sum in between mes so you

can follow along. I’ll start the game. 1 7 4 9 2 10 1 You’re just picking numbers randomly like

me, right? Uhh… yeahhh… Okay cool, 3 8 8 3 5 6 Seriously, though. We both have 50/50 odds of getting to 100. Um. Sure! Alright. 4 7 9 2 Uh. Wait. 89? If I play 1, that’s 90 and you can play

10 and win and… if I play 10 that’s 99 and you can play 1 and win. Oh, weird. I, uh, must’ve gotten lucky. Yeah, right. 5. [94] 6! 100, I WIN! Every. Time. Here’s how. Uhh..you can go now, me. Uh, fine. Well, I want a rematch later. I guess I’ll just uhhh…see ya in the mirror? Yeahhhhh. Okay, now let’s play a match between me

and you and I’ll explain along the way how it works. The easiest way for me to know I’m going

to win every time is for me to go first and start with the number 1. No matter what number you add next, 5, 3,

8, whatever it is, I just subtract your number from 11 to get my next play. So if I start with 1 and if you say 4, then

our sum is 5. To get my next number, I do 11 minus 4, which

equals 7, so 7 is my next play: 7 plus 5 gives our game a new total of 12. Then you say… 8. Cool. 8 plus 12 gives our game a new total of 20. I do 11 minus your 8, which is 3. So, I play 3 and our new total is 23. As long as I stick to this strategy I’m

guaranteed to be the first to 100. This is why it works. Regardless of your number, mine will always

result in a sum that’s part of an arithmetic series separated by elevens: 1, 12, 23, 34,

45, 56, 67, 78, 89, and… then finally 100. Since the highest number you can play in the

game is 10 — if I separate your moves by eleven… I rule the world! Or at least… this simple number game. Gotta start somewhere. When you play this with your friend can they

ever win? Yes. If you mess up the series. While going first, playing 1, and subtracting

every opponent’s number by 11 is the easiest way to stick with the series, after a few

rounds you might want to switch things up to prevent them from figuring out your strategy. You could do that by starting with a number

other than 1 and choosing wrong numbers until later in the game when you land on a number

in the arithmetic series like 67 or 78. So if you’re playing with a friend and you

pick random numbers until the sum is 65, then you could play 2 to bring your total to 67

and then you’re right on track. From there just subtract your friend’s numbers

every single time by 11 and you will be the first to 100. To players who don’t realize that the optimal

strategy depends on that series, this game seems like a game of chance — but once you

know the series, you have the secret number knowledge. But if adding up to 100 isn’t your cup of

tea you could try a similar game with matchsticks. These are Inq’s Durable Match-Like Puzzle

Sticks that come in the new Curiosity Box that is out right now. It’s packed with a booklet that features

22 different puzzles that you can try to solve yourself when you get these matchsticks. But for right now we’ll use the matchsticks

to visualize another game you can always win. Alright. You have eleven matchsticks spread out on

a table. You and a friend take turns removing either

1, 2 or 3 matchsticks and the player who picks up the last match loses. If you go first, you can always win this game. Since you don’t want to pick up that last

match, let’s work backwards to uncover the secret. We’ll play a game between Mr. T and Skeletor

because… why not?. Alright, let’s skip to the end of the game

to workout the winning strategy. If it’s Skeletor’s turn and Mr T. leaves

Skeletor with 2, 3, or 4 matches, Skeletor can leave T. with the final losing match. So, T. will want to make sure he leaves Skeletor

with 5, to guarantee that Mr. T keeps his jewelry. Here’s why. If there are 2 matches left, then Skeletor

just takes 1 and leaves Mr. T. with the final losing match. If there are 3 matches left, then Skeletor

takes 2, Mr. T. loses. And if there are 4, then Skeletor takes 3,

then Mr. T loses again. But if T leaves 5, no matter what Skeletor

plays next — 3, 2, or 1 — T can make a winning move and pity the fool accordingly. The arithmetic series that will rig the game

for T is separated by 4’s… 1, then 5, and then… 9. Mr. T. will want to leave Skeletor with 9

matches to make sure that ALL his plays match up with the series. If Skeletor and T start with 11 matches and

T goes first, that means his initial play will be to remove 2. Since each player can only remove a maximum

of 3 matches per turn, you can dominate the game every time by going first and making

moves that stick to this series. … which is why the game works with 20 matches,

too. To guarantee a win with 20 matches on the

table, your first play should be to remove 3 to land you at 17. So let’s say T. starts and removes 3 to

get to 17. No matter what Skeletor does, T just needs

to get to 13 to stay on course to win. So, if Skeletor removes 2 to get to 15, then

Mr. T. just needs to remove 2 to get to 13. Now T. needs to get down to 9. So, if Skeletor removes 3 to get to 10, then

Mr. T. just has to remove 1 match to get to 9. The next milestone is 5, so if Skeletor removes

1 to get to 8, then Mr. T can remove 3 to get to 5. And now it’s officially over. Skeleton can’t do anything — 1, 2, 3, it

doesn’t matter. Mr. T. is leaving Skeletor with the final

losing match. Let’s see if it’ll fit in his hand. What about this one? Good enough. Both the counting game and this matchstick

one are referred to as “Nim-like,” because they’re conceptually similar to a game from

ancient times that evolved into what mathematicians now call Nim. Players take turns removing objects from heaps

or stacks, and the player to remove the last object loses… but it gets a lot more complex

than sticking to a basic arithmetic series. We like complex. Humans have been inventing brain-teasing games

to pass the time, sharpen their minds, and extend collective knowledge for as long as

recorded history shows. One of the oldest games we know about is Senet,

with board pieces from Ancient Egypt dating back over 5,000 years. About the same time humans were inventing

the precursors to our modern written language systems, we were developing number games to

occupy ourselves and tease out a better understanding of the quantifiable world. Creating artificial challenges — and then

out-thinking them — is a way we exercise our minds. By discovering the hidden patterns that govern

reality, whether we’re just practicing with a matchstick game or unwinding the great scientific

challenges of our times, we’re engaging in an integral part of what makes us — us. Even those of us who use Skeletor to explain

math games. And as always – thanks for watching. Hey, the brand new Curiosity Box which includes

the matchstick game and a bunch of other awesome hand-picked, designed and developed science

toys is available right now. Michael, Jake and I created this subscription

box to bring physical Vsauce to your doorstep. So, check out the link below, it’s CuriosityBox.com,

to secure yours right now. I’m going to stay here and, uh, try and figure

out some of these puzzles. Alright. Move one match to make a square. Uhh. Um. SQUARE.

LOL

I played that game 10 years ago and i thought i just made a new game. I also knew that fakt with 11, you can ask all my friends, it's true. ^^

Shquare

This is the mathematical way to ask for a kiss.

No joke

oh no

WOW

What The what??!!!?!?!!??!?!!?!???!?

Basically NIM

Well yeah you can always win because you have no one to play against but yourself

dont spam because google shared is gonna get terminated

I know how to play senet

actually it does no matter who is the first if you` re good in math… no? O.o

Nobody:

No one:

Absolutely nobody:

Him:

VSAUCE KEVIN HERE!mach game is like 21 always get multiples of 4

Have the developers patched the cheat yet?

som big rigs man vinner alltid

Already got how it works when you were playing

Pls may you an example when it is how to win Legs 11 because I know it is almost the same principle however does doing it with more than 2 players alter the arithmetic series? Thanks 🙂

what about with

3 playersПИСОООС!!! зэ гейм ю кэн олвейс вин…

ok

My 6th grade algebra book has a game like this. The rules are:

(Of course this is a 2players game)

1. Each person say a number from 1 to 3 (for example the first person say 2)

2. The next person say a number also from 1 to 3 and then add to the first person number (for example the first person is 2, the second person say 3 then you have 5 in total)

3. Whoever gets to 20 first wins

Brother: That Yoghurt is mine!

Me: NO! It's mine! Let's play a game! It wor….

Brother: IT'S TIME FOR A D-D-D-D-DUEL!

Me: CHILL, IT'S YOURS!

This was released on my 9th birthday.

Hey Vsauce, Micheal here: You're weak.

Vsauce, Kevin here: I'm you.

Didn't you say something about your evil twin from the future in a future video… I guess he was good and willing to play in this past video.

If you play yourself wouldn’t the other you know what to DO! Hummmmmmmmmmm😮😮

I know how he always wins. He is playing himself

Look out guys, he has half hot half cold

Thanks man

Number game against me be like

Kevin: 1

Me an intellectual: -3

One simple explanation is get a number which is just one didget ahead of 11's multiples. Like 11,22,33..

If you play the game with… Yourself? ofcourse you will win always this doesn't require math its just the facts

You can also do 10-X+1

Right?

I used the first trick and lost

I saw what you did before you even explained it

is Mr t or skelator the one we want to win?

0:20

……….heh

So none of my friends are as obsessed with math as much as I am, but I have realised that this could make a fun and destructive drinking game to play and obliterate your friends with if you so choose. The person who loses? Oh yeah, you have to do a shot.

Good times.

madlad just memorized his own numbers and the sum two times

My friends are too lazy to mentaly add the numbers.

Bob have 1 friend. His friend also watch this video. How is he going to win?

You lost too ya know

This is a math game u can win 80% of the time with a

normal personu can’t choose a smart person cause u have a 50% of losing

U can use this to gamble

1+1 = 11

2+2 = 22

3+3 = 33

4+4 = ?

it’s 8 not 44.

The loneliest man

I have a game that i always win, it is called

First to say 'alligator' wins

I already said it

Bob

Go

Me

💯

I win

Wouldn’t it of been 50/50 if we both knew the strategy?

Michaels better…

Who gotten a pewdiepie ad

I have another game that’s a lot like the match game but you don’t have matches.

It’s called unlucky 13 and you can play it with as many people you want (but to ensure you win you must have 1 other player)

So what you do is you count up to 13 and the person who lands on 13 is out

You can only say 1,2 or 3 numbers at a time

For example, you could say 1,2 and the next person would say 3,4,5 then the next could say 6 and the next 7,8,9 and the next would say 10,11,12 so the next person up would be out because they would be on 13

To always win you have to let the other player go first. You got to make sure you first say 4 as your last number, then 8. Then you are ensured to win. They could say 1,2 or 3 numbers but it wouldn’t matter. If the last number you say is 8 no matter what they say you can always win.

Ever play Nim

So what if ur friend watches this

0:19

When NNN ends

Me in december: i’ll just play with myself

6:06 what is he doing to Mr. T😂

Aaron paul??🤨🤨🤨😂😂😂

To cut it short, 11-x(x being the number they said)= your next number

This video just proved why mario beats luigi (p1 p2)

after you said one iPic 99 so

(⁹⁹_)

FALSE!! the other person can just make the number 10 every time

I always knew 11 was a lucky number!

anyone can win this game

you need a friend

me: :'(

The struggles of writing on a whiteboard left handes.

he one

Don’t know why I watched this I’ll never play these poxy games.

6:36 bad pun alert

You look practically identical to Alex Hirsch with that red plastic on bro

I’m too bad at math to understand

Basically

11-n

&

4-n

Bruh

I had this as a math problem in 6th grade. this was my formula exactly

I always win this game no matter when I play(most of the time)

Even when I play with a friend who knows this

Is there a way to win if you're the 2nd🤣

"vsauce! kevin here!" exerts massive chaotic evil energy and always will.

My friends are dumb they’ll never figure it out

Dude has no life

Well i have no Friends (im not joking btw all of the people that live in around my house don't have any Friends)

Kevin>>>>>>>>>>Michael

I lost.

Cool

What if my friend watches this video who will win?

Kevin: Choose numbers from 1 to 100!

Me:Ok. You go first!

Kevin: 1.

Me: 99! I win!

Kevin: Oh. Why?

Me: Well, duh. 9 and 9.

Vsauce2: You need a friend

Me:

cries in mathematicMe clicking on this video: "Oooh, I can screw with my friends with this."

requires you go firstWho remembers this game in an episode of cyberchase? They played it with red and green dragons or something.

Well if you play against yourself, you win no matter what you do

Him- you will win. No matter what they choose

Me- Eleven

Also me- EHHEHEHEHEHE

Vsauce2: Plays with match sticks

Smokey the Bear:

🤯🤯🤯🤯?!?!!!!!?!?

I saw a pattern straight away

Thank you, HAHA i used it on my friends to get what i want 😂 asked them to play a game with me and they never doubted me that im calculating in the number game 😂

The one game you can always win is: I win!

Pinkman !?!?!

I recommend using a calculator

Right after he said "play a similar game with match sticks" I got an ad for jumanji that started out by saying "find the jungle"

“A game you can always win”

“A game you can never win”

the duality of man
