I’m gonna show you a game which seems difficult But! I’f you learn one simple trick, and i’m serious it’s genuinely this one simple trick The game becomes, so easy! Most people can be beaten by a piece of plastic, From the sixties. -music- Here’s the game of Dr.Nim I managed to find and buy online It came in a fantastic original 1960s box check that

out You can tell us nineteen sixties America

because there’s a wholesome family having fun with guns in the background! The game

starts with the row Marbles along the top of the board there, and the goal is

to take the last marble, whoever gets that one there wins the game, and each

time you have a go you can choose to take one two or three

marbles. but who am I going to play against? well

for dr.Nim you play, the piece of plastic itself

there are levers and things that toggle and bars underneath it will make its own

moves and in theory it will always beat me as the human i get the luxury of

going first there’s a little toggle down here it is on the left and means it’s Dr.Nim’s go, if it’s on the right it’s my go as a human and whenever I

want to release a ball i just hit the button on the side there there goes the first one and you know

what, i’m going to do two marbles on my first go so now I move the lever over to Dr.Nim’s

side and to set Dr.Nim going you hit the button once and it will choose

how many marbles that wants to take so here we go, going for one, oh wait it’s

gone for a second one oh! So it took two marbles and then moved

the lever back over to indicate it’s now my go well I only want one, so there’s my one

and it’s made it through, ever so often we get stuck I now go fine, dr.

Nim all yours I took one, what are you going to do?

that’s going for one, going for a second one its gone for a third one, and then switched

it back to my go okay there are four left, I think dr.

Nim may have me in a corner here, i’m going to take, oh goodness I’ll go with two again there’s- actualy you know what? Just one, I’ll do one, and gonna go straight back to dr.Nim, and you’re on dr.Nim one second, one and the winning third one and just to

rub it in as it winds it puts the lever back over, to say it’s now my go… …to suck… No matter how many times you play doctor

Nim, the plastic jerk as long as the human goes first as long

as you play by all the rules and don’t cheat it will beat you every single time this is based on a mathematical game

called unsurprisingly, NIM, and this is a plastic computer that has been built to

be any human in a simplified version of NIM, NIM is a great game to play it like

this piece of plastic you’re a big fan of beating other people

and i’m going to teach you how to always win at NIMH so you can use it to annoy your friends

and family, – music- the game of NIM has been known about

and studied by mathematicians for, well over a century, although people believe it

predates that by a long way specifically what we’re looking at here

is a version of NIM called single pile NIM,for dr.Nim all the marbles

came off one row the version i’m going to show you, all these coins will be in a

single line technically proper NIM can have more

than one pile, but believe me the strategies for multi pile NIMH get a lot more

complicated as very much another game for another video the way I would normally play NIMH in a bar

or similar setting against friends strangers you know, chumps, would be to

use something like 12 coins we start from one end each player can take one

two or three coins whoever takes the last coin wins while I

absolutely never encourage any form of gambling if you were the kind of person

who would like to do that you and your opponent can both put some money on the

game put it under the last coin or token and

whoever takes that one gets the cash, in a similar vein many years ago we were

involved in setting up something called mass of asking where we went outside and

did busking with mathematics on the street one of the routines involved putting 12

pigs on one of our buskers the 12 peg had 20 pounds underneath it very importantly 20 pounds of our money

but we knew if we played the correct strategy we would always be able to win

the game and keep money some people found that pretty annoying

they would go away come up with strategies come back trying to beat us, in

fact there are a few ways people can try and get you in a corner where you can no

longer win but I’ll get to that in a moment to start with here’s how you win 12 coin NIMH, a nice

way to start is by looking at the end game i got myself in before with dr.Nim

i had for marbles left or in this case for coins it was my go, and i knew i couldn’t

possibly win, and if you get your opponent in this situation you can always win

because if they take one you take three if they take to you take two they take

three you take one and they can’t take four according to the rules, so the goal of the game is to get

them into this situation but how do you guarantee that situation well imagine it earlier in the game and

there are eight remaining and it’s their go you’ve got the same deal going on with

just these four to leave these four left if they take one you take three they

take to you take two they take three you take one as long as

between them and you you take for away you’ll be left in that end game we can now go one step back to the very

beginning of the game where there are 12 coins all together you’re thinking of them in lots of four

for there for there for at the end for each round of full the other person goes

first you go second you need to make sure you

take enough coins after their go so between you you have taken four in

total once you know what’s going on it’s a very straightforward game to win

they take one you take three they take to you take two they realize

they can’t win they get annoyed you get the money the only problem arises when people

realize the trick themselves and this is what we had when we were basking people

would go away work it out come back and then they

would insist that we go first instead of them, so what you do is if any

of your friends caughten on to what you’re doing the next time you reset it you do what

we used to do you just take out an extra coin and put it on the end we would

suddenly increase the number of pegs to be greater than 12 you go first and you bring it down to

the now multiple of 4 it’s they go and you’re right back in

your winning situation -Some Extra Radical Music- so how does dr.Nim the piece of plastic

play by those rules with the top we have the 12 marbles as we would expect and then underneath that we have a

series of these little toggling plastic Levers, they keep track of how many

models have gone through the game so far and you can think of them as kind of

like a binary counter but it’s not true binary it’s more of a tally system that

keeps track of the marbles you start with the leftmost one up and

the other two flat down the first model release drop the left one that raises

the center one if I then send a second one it drops the things one raises the

right one the third marble just restore the right

one to being flat only when there’s a fourth marble your

left my one get raised back up again and we’re right back to where we started

that repeats every set of four marbles after they’ve gotten through what are

now calling the paddles the marbles can go one of two different ways they can

either go to the left or they can go to the right, if its Dr.Nim’s turn and

the switches over on their side any marbles which go to the left will

bump the switch over ending dr.Nim’s go any marbles which go to the right hit the button and release another

marble so we need to save from the different arrangements of the top three

paddles and it keeps track from each set of 4 is the first second third or fourth

ball do they cause dr.Nim’s go to end? or do

they cause them to take another marble let’s have a look i’ll just cycle

through a few marbles and will keep track first Marvel out ends dr. names go

second marble you take another ball third marble take another ball fourth

model and the go and it carries on like that first one will end his go on the

left second one goes to the right take another one third one go to the right

take another one for one goes to the left ending their go so what does this mean for dr.Nims

strategy where you can imagine all 12 marbles at the beginning works in their

groups of four and for each one it’s dr. him get to go on the first

fourth model they’re going to call their go to an end if they get to have a go on the second

or third they’re always going to carry on to another one when i first got the

game and I was investigating how it works actually found that a little bit odd

because dr.Nim doesn’t have to end their go on the first marble in theory

the human is always going to have the first model from each set of 4 why is it designed to go to the left is

it just easier to build that way It turns out if you read the admittedly

casually racist instruction manual you see they’re acting all different

ways of playing doc turn in their options for dr. need to go first and you

can do the same trick you can give them extra marbles the doctor named will just take straight

away in there are other versions where you have a fighting chance there are some versions of this game

where you can actually beat dr.Nim and that’s what this little paddle here is

for is called the equalizer paddle and you can set that so initially doctor

named doesn’t play with perfect strategy you get a chance at the beginning to

beat it but if you make one mistake it will take

over return to perfect play and you’re not going to win, and that’s why dr.Nim

has to end its go on the first position as well as the fourth position it would

only end in the fourth position there are some versions of the game

where you may have ended at a whole round of four in that case dr.Nim would take four

marbles that’s against the rules and it will have cheated and whoever designed

the dr.Nim game to their credit they made in such a way

that it will never cheat it will always play within the rules

admittedly in such a way that it would normally kick your ass so they are that is the game of dr.Nim, I find it absolutely fascinating as an example of a very early computing

based game the instructions for all their drawbacks

to go into a surprising amount of detail of the theory behind how dr.Nim

actually plays so you can see here there’s a whole section next to that

fantastic caricature which talks all about whether or not machines can

actually think, if you like this kind of real-world ridiculous physical computing

then you’re going to love my Domino computer check it out – thousand dominoes arranged in a pattern

such as they can do binary arithmetic if you like this general concept of

fascinating mathematics of course make sure you subscribe to my stand-up mass

channel and if you like winning drinks money or just admiration of your friends

when you do that how to playing them and please do go beat them -Last bit of Epic Music-

Took me the whole video to realize where I saw this dude before. Outrageous Acts of Science!!

How does he have 2 hairlines but still no good hair

but what is the mechanism that makes it decide wether or not to send 1 2 or 3 balls down?

Sack your barber, mate.

(13 coins) the goal of the game is to get them into this situation…

(12 coins) but how do you guarantee that situation…

This guy can beat a 60s "AI" game with ONE SIMPLE TRICK! Dr. Nim HATES him!

He moved alot in the chair when he was getting his hair cut

British accent, USD notes, River Thames, what a Nim

It seems related to the Turing Tumble educational game https://www.youtube.com/watch?v=iSjx6uh8MFg

Am I the only one who noticed there’s 13 coins?

Remember a similar game from my Uni days – 15 coins/matches arranged thusly;

X X X X X X X

X X X X X

X X X

Two people take turns to (in their turn) take as many matches (etc) as they want, but only from either the top, middle or bottom line…

The last match is the LOSING match, so avoid picking it up.

The premise is "you can go first or second, I don't mind, but I'll win 99% of the time"

Yes, it's an algorithm, but have a go.

No, really, have a go…

A variation of this game was used as a challenge in the early seasons of Survivor.

The aughts were such a simpler time

I play this game to 21

We call these pseudo games.

odds and even maybe?

With total number of units divisible by n(number of choosable items)+1 , in this scenario, the one who begins will never win.

Dr. Nim hates him for this one simple trick

anyone 2019??

Is this where “for all the marbles” comes from? 😉

*Looks down to see if someone else took this comment…

Dude, what's up with your hairline?

I've seen this video multiple times, and this is the first time it occurred to me: he's using US money.

is a better game with pictures of guns in the back. those PICTURES are pretty dangerous and might jump off the wall and go crazy…………

This vid is recommended every year to me.

That's pretty friggin' cool. Always amazed with the clever ways engineers could 'program' arbitrary rules or mathematical stuff to play out via purely mechanical means.

Isn't the trick to leave him on number 4?

9:32

What's wrong with his hair?

My classmates played a game called 11. Whoever gets 11 sits out. We can say up to three numbers like 1,2,3. Then pass on. So if there are two players left whoever is first garanteeds ein if they do the correct thing. So they must say up to two, which then the opponent must pick 3,4,5. Then you stop at 6. They must say 7,8 or 9. Which then means u can say 10 and they get 11. If you dont say 2 you basically f#cked up.

Shave it, dude!

Where can i get one?????????

Idea: have 13 coins. Line twelve of them up, and flip the last coin to determine who will go first. If the flip says that you go first, add the last coin to the line, and act like that was what was going to happen all along. If the flip says that they go first, pocket the coin, and act like that was going to happen all along.

8:51 It looks to me the board is made to be reset by simply tilting the board and moving the marbles up the shoot to the top again, or am I missing some statistical significance?

The only thing I cant decide is if he recorded this at his mom's basement or his victim's!

Dr Nim – a quarter century BEFORE "Deep Blue"! I was a kid back then but had no idea we were ALREADY so close to A.I.

It’s like you are playing with a ghost

How does nobody notice an extra coin when they want you to go first?

Winning should be pretty easy even if you go first

I lost interest

Cool video! Are you on BitChute?

Every time I hear the word lever I think of The Emperor's New Grove.

"Pull the lever Kronk.

Wrong leveeeeeer!!!!"

What happens if you just keep pressing the button?

I was wondering what happened to this guy after "You have been warned"

How to win 12 coin nim….have 13 coins

Wow this is my game, I don’t need friends to play this game with

“It turns out if you read the admittedly casually racist instruction Manuel” 9:31 I wanna know what’s in there 😂

6:56 Cheeky bastards.

Just cassually put another coin and hope they wont notice 😆

OMG, i learnt about it at informatics to code the game to predict who would win using the xor

Who else is going to mess with their denser drunk friends? Of course I will, it's pretty much math magic. 🎩 🔮 Thank you for posting this. Neat purchase on that game.

Ok

This game reminds me of that mini game from Tales of Phantasia, and remembered myself writing some sort of number patterns to "trap" the AI for me to not get the last piece of stone (instead of getting the last piece to be the winner).

Ahhhhh, those were the days… 😌😌😌

More people have shown interest in this old toy from this video than the real life item.

Thanks for the gambling tip. I'm swimming in money right now.

this game looks pointless

I already have a strategy LOL

P.S. You don't have to add a coin. The reason there are three sets of four, is because that gives you the chance to win, without adding a coin. It is because 13 is a prime number and 12 is a factor of 1*12, 2*6, 3*4, 4*3, 6*2 and 12*1… You can "set them up", prior to the last set, with any combination, without the NEED for another trick, on top of the math-trick. It is just easier to do, by adding a coin, and easier to spot and easier to catch a lazy cheater. 😛

The importance of the factors is… {3 groups of 4} and {2 players with 1 winner}. Or, {4 groups of 3} with {2 players and 1 winner} which requires 12 pieces to the solution/answer. (See where 1,2,3,4 and subsequently the 12 comes into play now? 12 being the common "factor" among those numbers.)

The three groups of four are NEEDED in order to ensure that you, no matter when you start, can win, if you know the "setup". It is just easy math, if you go first.

I want to see the circuitry at the back of the game.

2:56 Ummm…

There's a version of this in Mario Party called Honeycomb Havoc, but it's a little different. That one has traps of beehives placed every so often in the sequence, and you're trying to avoid collecting them.

Os it just me or are there 13 coins on the table for the first half of the video?

i literally had a player in a DnD campaign use this to trick the BBEG out of a world destroying weapon… "I challenge the Warlock to a game of Nim"

Warlock (me as DM) rolled a 1 and thus, the Warlock fell for it…and went first…

Gotta say, it was a smart move from the party's Barbarian, who was the only one above 1/4 HP…if they had tried to fight it would have been a loss…

I worked out how to win this game every time when I was 9. I have always loved working out things like this.

Solved games are fun!!!

In the 1960s, guns were not uncommon in the UK. it would be part of British culture, historic guns were on display. At some phases, the whole 'African Hunter' thing would be a big cultural thing in the UK with 'elephant guns' on display with some tusks maybe. UK 'Spy Movies' were the western rage and Bond with his classic pistol was a very british scene.

but the thing in my family history as with so many Brits – WW2. Mind you, people didn't like to display them but plenty of homes in the UK had the owners WW2 confiscated Luger, service revolvers, yes.. military machine guns. As for displays many had a prominent photo of the WW2 family member who died (or just served) displayed with their rifle often in the family sitting room.

This idea that Americans have 'gun culture' and acting like its some bizarre thing.. that's very very recent and part of New Orwell Britain.

So drawing an Asian cartoon character is "mildly racist"? Dr. Nim is supposedly a genius at winning, so I'm not seeing the racism I guess…

I had one of these when I was a kid. I was fascinated with it. I'm thinking that this may've been a reason that I eventually became a software engineer.

Definitely don't explain the objective, I mean everyone knows how to play Dr. Nimm….

omg his hair

DUDE YOU HAVE THE MOST UNIQUE STRANGE PATTTERS OF BALDNESS I HAVE EVER SEEN LOL.. its like a perfect u. if you look straight on you have hair but tilt an inch to one side or the other then you see Mariana trench. so my advice never move your head just look dead straight on for the rest of your life… unless you lose the rest then well your just screwed and should shave it off.

For the game 21 it’s the same go second you always say 4 then 8 then 12 then 16 then 20 and you win

That is so deviously simple

Bet you wish it was that easy to fix your hairline

Huh! I thought this would make me feel stupid.

seems same as https://www.turingtumble.com/about/
