The Gilbreath Principle. "A thing of terrifying beauty." -Max Maven.

I was wondering, when setting up the deck, do you put them in order of number and color? How is it the 10 and 5 come up? Couldnt it be just a random number, but you still know the color?

Easy to explain: if you didn’t shuffle the cards and you split them in 2 x 10 cards piles, one pile would be all black and the other all red. Now that you have shuffled them, each “inconsistency” means that the two cards have replaced each other.

Brilliant thanks man!!!

My intuition is telling me to suggest that you should set your camera to manual focus for the over-hand sequence shots, so that the camera isn’t changing focuses each time your hands move across the center of the screen

The Gilbreath principle is amazing and i like the idea of the spectator trying to cut half the cards as the excuse to reverse them 👏

I like it . I like doing mostly Impromptu cards tricks, however If I didn't I would snatch this one up. Great job ty for the tutorial. I am subscribing . =)

Love it. Thankx for the good tutorial

Damn gooooooood one .TY Steven

Wow great trick and very unexplainable. Even if the shuffle isn't perfect it still works. Amazing tutorial again. Great work

A wonderful Trick Steve. This principle, 7:06 as so many uses it, can't be explained 😊👍😊👍😊👍😊👏👏👏👏

I don't know card tricks, and I definitely can't "fan shuffle" or interlace them like you did. So, it seems the trick requires that the spectator know how to shuffle in the manner you show, right? (Google says it is riffle shuffle. I would likely ruin the pattern).

I would do the first count into 2 halves with a face down pile so the alternating black and red won't be seen.

Amazing trick Steve, so right definitely a fooler, thanks for all your hard work to make ours easy.

great trick and video. thank you

Great tutorial - thank you. But please disable your auto-focus setting next time so it doesn’t keep trying to focus on your hands that are coming in and out of your shot.

Cool trick, thanks. Btw, in the one shuffle, they might turn the 10H to the 2nd in the deck (and it will go to the magician's deck) so you'll need to notice and take a pick at the new top card if that happens.

5:08 order of colour is 1,1,3,2,3. Remember the sequence and set cards aside.... then count the cards upside down and reveil them in colour piles after 😊

Hey thanks, very cool ! First card trick that actually works when I do it.

Great trick, but every time I practice it, I make a pretty accurate cut, then count out one stack to reverse the order and put the 5S on top, leaving the 10H on top of the other stack, then a riffle puts one or the other top cards on top, then when I deal out 10 cards each into 2 piles, the cards get clumped back together in large groups of red and large groups of black. Like 3-6 in a row of the same color. I want them to look more random. What am I doing wrong?

Actually, you don't need to do a magician's force for the 10 packs if the cards are "opposite". That's a needless complexity. In fact, it works better if the spectator has a completely free choice between 10 packs.

As long as you remember to tell the spectator to do a riffle shuffle, most would just go into an overhand.

Brilliant!

Hey Steve, just curious where did you announce the winner of your Holy Deck giveaway? Still volunteering here haha 🙋‍♂

Great trick. However, the way it’s done the spectator would notice the red black pattern when counting how many cards were cut. It works exactly the same if the deck was cut and counted with the deck face down

Yeah it's incredible that I can look at a pack of playing cards and tell you which 10 cards aren't in it ...

Can someone help me? Can you please tell me where I put the mind reading kicker card at the end, because I put the ace of spades and ace of hearts at the top and bottom of the deck at the start but they didn’t end up as the bottom card at the end for the mind reading kicker. Please can you help ASAP. Thank youuuu

The Gilbreath Principle works a follows: You have two stacks of cards, one that goes R-B-R-B-...-R-B and one that goes B-R-B-R-...-B-R-B-R. They are shuffled together, meaning a new stack is created and 52 times, the bottom-most card of either stack becomes the new top-most card of the new stack. The first card has a choice of being either B (left stack) or R (right stack). Whichever we choose, the second card can only be the opposite, no matter what stack it comes from. Adding this second card necessarily makes it so for the third card, we have a choice again. The fourth card will be the opposite of the third. It's now easy to see how, in the new combined stack, every other card is precisely the opposite color of the card below it.

Asi Wind's Red and Black. And it's good to Not fully interlace the cards after the riffle shuffle and display them spread vertically.

I just recently learned it: Spidey - Out of my Mind. However, Peter Turner also included it in his How to Read Minds (2?). Good trick!

Gosh that’s amazing- thank you.

Does the shuffle need to be this shuffle type. The spectator may shuffle differently

Okay, it looks like it can be streamlined in a couple of places to make it smoother and also to remove the force.

Is this a similar trick as in a video called "Shuffling Card Trick" on the "Numberphile" channel? They were trying to explain the mathematical reason why the trick works but I only understood maybe 30%-40% of video.

For unexplainable trick, you explained it relatively easily. If you split the deck in half you create two identical packs of alternating cards, due to the number being even in the deck. Both have the same alternating order. Now if you reverse the other pack, when you shuffle them you not only have an alternating order in both of the packs, but also alternating between the hands. So if you shuffle perfectly, they'll be in alternating order, but if you shuffle multiple from the same hand, they are also in an alternating order. As such when you deal them in pairs, they'll always keep the alternating order. When you see one person get multiple of the same color in a row, that's where your shuffling was imperfect, but due to the alternating order in both packs the pairs are still alternating.

I’m 25 , went to Vegas and re found my love for magic . That part when you taught us “magicians force “ was actually genius ! I never could of thought to manipulate the situation like that

Could you set it up so you could know the exact card not just the color

Hey, quick question: Why must I Magician's Choice the pile? As they are opposite, whichever I have to find, I can do it by peeking at the other. And I can also find the last card in the same way. Thanks! Cool trick.

This relies on a very specific method of shuffling - what if the spectator decides to shuffle it a different method? One that will mess up the alternating order? In my mind, you still need an "inside spectator" for this trick - one who will always shuffle the deck using this very specific (albeit most common) method.

UPGRADE on the trick is to quickly memorize the red/black order of your cards and then define their card’s color order without the deck spread out.

I've had 8 Maker's and cokes and tried to follow along watching this. It seems VERY impressive, even if I have not been drinking... but alas, I've failed even the 1st prompt, as a drunken magician!!! What I've learned: don't drink and mage!!!

But what if I shuffle the cards a different way?

ok, after the shuffle and piles of ten I ended up with all 10 cards red in my pile and 10black in their pile!! 😆 🤣 😂

A lovely trick, I’ve performed a version of this for many years, it still baffles me how it works. 👍

why do you force the first pack if they are opposite?

Why should you force audience to choose the one pile, if its just the opposite and 10H vs 5S, then you can just work with any of the pile? Just curious.. Thank

Very simple explanation. When you have cards perfectly set red/black and then you do one simple riffle, you're going to displace the two colors equally.

As soon as you let the magician touch the cards, it becomes explainable.

This is all super smart, great video! I see how it works but I don’t understand how even after a random shuffle the two packs of 10 end up being symmetrical in color???

It's indeed a mind twister. But definitely can be explained

Brilliant

can do only one riffle shuffle ?...no cut not two times and no overhand shuffle ?

Why force the pile to the spectator? It works with any pile they pick, does not it? (if you don't want to get the last card I mean, but it is without force whatsoever)

I think counting the cards face up throws it because looking at it from a spectator i can clearly see they alt red black which your telling how the trick is done right there.

Gotta buy a deck of cards and try this.. seems fun

so what happens if they suck at shuffling the cards and don't do a perfect riffle shuffle? wouldnt that make it not work?

Why do you need the force if they mirror each other?

Thats so cool to the max

It seems to not matter which pile they pick, the colors are always opposite, no magician's force needed

Pretty simple to explain actually. The only thing is it doesn't work if the audience member doesn't shuffle the top two cards correctly for guessing the number and the suit. You can only do the suit colors at that point.

Why did you have to force the pile? Wouldnt it still work regardless since each pile is opposite of each other?

Pretty obvious that the black-red mix results in even numbers and placement of cards. Any inconsistency in one hand will show up as the opposite in the other hand. You don't even need to force a hand because if you know one, you know the other, so it doesn't matter which one they pick.

I can explain it. It's not that difficult to explain. I'll give you a clue: when you arrange them red & black all the way through - that's an artificial pattern that never changes it just repeats red/back over & over. Then you do 1 cut & 1 shuffle. That's it. that puts the inverse of the new shuffled pattern with almost perfect reciprocal r/b r/b pattern except that has a slight chance of throwing this off but it's mitigated by the fact that you deal off the top 20 cards - which eliminates the differences at the bottom of the shuffle - making a perfect mirror image of the cards in the left & right hands. All you have to do is read the image on one side or the opposite on the other side. This is easy to discern. It took me much longer to type it out than the 30 seconds it took to realize how it works. I left out details but I told you more than I was going to. The details I'd add would further clarify things that are obvious to me but I've told 90 percent of the story.

It falls apart if the person can't shuffle very well. Most people can't do an accurate shuffle

Why do you need to force the pile? Could they not just pic your pile and you can read off the opposites with the pile containing the 10 of hearts, that way you'll predict their 5 of spades?

don't have the hand dexterity or focus to do something like this, but it looks cool.

Good trick, but from what I saw, the one part that can get dicey is the last card/10 of hearts reveal. I noticed the 5 of spades and 10 of hearts were the top cards of the two piles, then the spectator shuffled. The ending would need those two cards to remain on top, so a bad shuffle could easily have buried those 2 cards past the top 2 positions. I guess you can watch the shuffle and see if that's what happened and if it did, then you can eliminate the last card prediction...the rest of the trick is still very good. I'd be curious if this observation was wrong.

I have 2 questions. What happens if the first cut gives an odd number of cards? And why do you need to force the 10 cards packet as both packets should be the exact opposite of the other?

I'm still confused, but if the deck is then shuffled twice it's truly mixed up. Then the magician is screwed.

when the penny dropped I thought 'WOW!' then 'OH! NO!' the type of shuffle

Another great on

Brillant effect

Thats amazing!

Does it works also with more 10 cards?

Choice bro!

I get the color part but I don't understand how you know what the last card is.

3:21 yes red black red black and 10 on top. then shuffle then so 10 comes top. rest triick is work automate

Without the kicker you can have them really pick any of the two piles - no magicians force needed

Wow this is weird how it works but I can’t get the kicker ending to work…..maybe my riffle shuffle isn’t good enough??

I would let the spectator turn over the cards at the end. In fact, I would let them block the cards with their hand so I can't see the cards, eliminating the possibility of a marked deck or sleight of hand.

I get it, pretty simple. Thanks 🤘

Legend has it, that this freaks people out

Thank you

Try lucky number 13 next

This is purely mathematics, trust I know a similar trick and can be done by anyone, it's been more than thirty years and cannot be figured out. Sad thing, I cannot type that all here. Truly magical. It's called the 21 card magic. Purely mathematics

Should you be counting the cards faceup? The obvious alternating red and black pattern seems a dead giveaway.

Of course, this requires the spectator to do a good riffle shuffle.

A easy solution could be that the cards are marked with black and red. And you just need to look out for the missing card.

This is a wonderful trick

Nice one, yet I can not help but feel it would be better to count the cards face down so as not to show the sharp-minded that they are black red black red.

I’m terrible at riffle shuffling. Would never perfectly alternate every single card and would break the trick.

You’re creating a mirror image of the cards only opposite when you divide them.

Does it have to be a riffle shuffle?

shuffle.... lol.. shuffle on bottom.. put on pile from top.. revelaled. thankyou

I always click on these videos, but I always close them before they give away the secret. I still go to clubs to watch "magic tricks".

Or just use a marked deck … or put them in stack and false shuffle them

Problem will be if the 'spectator' cannot shuffle the cards that way. I can't and I am handy with cards. And I would not be able to choose even which left or right would go first to bottom. No way the cards would really go evenly one right one left. So many ways to make this fail. You definitely would not fool P&T with me on the deck!

Ignore all the dip shits that criticize the video and the card trick. These are people with no life that spend their days looking for videos to pick apart, which helps explain why they spend their Friday nights with a porno magazine and a pint of cheap whiskey. I for one enjoyed the card trick. With enough practice I may try to use it one day. I always enjoy learning something fun even if I am not coordinated enough to do it as well as you demonstrated. Thank you for sharing it with us

The magician will be at his wit's end if somebody shuffled the cards ten times. You can manipulate the order of the cards when done alone.

Sorry, but too much to learn for me! Nice job with the video Steven!!!♥♦♣♠
