This self-working card trick demonstrates how a mathematical procedure can produce a predetermined outcome despite seemingly random spectator choices. The magician begins with cards in a specific order (ace through 10 of hearts plus a joker), performs a shuffle that reverses the order, places the joker on top, and discards the bottom card. The spectator then repeatedly cuts the packet, divides cards into piles based on the top card's value, stacks piles left to right, and discards the new top card. Despite the apparent randomness of these choices, the procedure is mathematically guaranteed to result in the joker being the final survivor while the discard pile forms a perfect sequence from ace through 10 of hearts.

Random Choices… PERFECT ORDER 💎 (Self-Working Card Trick)Added:
Okay, I have a new effect to share with you today. As you can see, I have the ace through 10 of hearts and a joker up here that we'll use in just a moment.
Now, since we saw the ordering of the cards, why don't we go ahead and just give them a little mix here. This is the mange over under, great way to mix. So, we're going to place the joker, as you can see, right on top. Now, actually, I only want uh 10 cards. So, why don't we discard the bottom card after mixing it well. And so, how this is going to work is I'm going to have you make random cuts. Now, if you happen to cut to the joker, I'll just have you cut again, okay?
Because here, the joker has like no value to it, okay? So, if you can just come in here and randomly cut that wherever you'd like, okay? Complete the cut.
Okay, so what card have you brought to the top? Oh, it's a four, okay? So, how this is going to work is I'm going to push off cards into piles until we have four cards total. And then, I'll just stack the piles from left to right, okay? So, once again, you got a four.
So, how would you like to divide up four? Two and two, one and three, three and one, your choice. Two and two? Okay, so this is how it would work. You just push off two, push off two, and then we'll just stack from left to right, and then discard the new top card, okay?
Uh can you come in here and in fact, maybe we'll discard it here so you can reach the cards. Can you go ahead and randomly cut wherever you'd like, okay?
Very good. What card have you brought to the top? Oh, you brought the four to the top again. Okay, how would you like to split up four? You want to do three and one or one and three this time? Three and one? Okay, we can do that. So, three there, one here, stack from left to right, discard the next card, okay? Very good. Uh can you come in here and cut it? Okay, so maybe you'll just come in here and cut it like that.
What have you brought to the top? Oh, a seven. How do you want to break up seven? You want to do one and six, two and five, three and four, what would you like? You want two, two, three. Okay, very good. And then, we'll just stack from left to right and discard the new top card as before. Can you cut the packet wherever you'd like, okay? Right there, complete the cut.
Very good. What have you brought to the top? Oh, a four again. Boy, you really like that four. How do you want to split it up this time? Two one one? Okay, that's fine.
>> [laughter] >> That's a little different. So, two, one, one, because that adds up to four, that's just fine. Okay, we'll stack from left to right, discard the new top card.
Can I have you cut the packet wherever you'd like, right there. Very good. What have you brought to the top? I can't believe your luck here.
How do you want to split up four for like the fourth time? Just two and two?
Okay, two there, two there, and then we'll stack from left to right, discard the new top card, okay? Uh can I have you cut it one more time, okay? Very good.
Okay, what have you brought to the top?
Unbelievable. How are you doing this?
You want three and one this time? Go three, one, stack from left to right.
This This is a miracle in and of itself.
Okay, can you cut it anywhere you'd like? Right there, okay? Very good. What have you cut to? Oh, a three. Finally, you got something different than a four.
How do you want to divide up three? Two and one, one and two, or one one one, it's up to you.
One and two? Okay, so one card there, two, that makes for a total of three.
Stack from left to right, discard the next one, okay? Can you cut the packet one more time? Okay, very good. Complete the cut.
What have you brought to the top? Oh, a two. Okay, very good.
So, how do you want to break up two?
Just two or one and one? Uh one, one, okay? And we'll stack from left to right, discard the next one. Okay, do you want to cut the packet or just leave it the way it is? There's only two cards. It's up It's a free choice. You want to just leave it the way it is?
Okay, very good. Oh, you got the two again. How do you want to divide it up?
I guess there's only one way. We can Well, no, there's two ways. We can go like this, or we can You want to go one one? Okay.
Stack from left to right, discard the next one. Okay, wow, that was a lot of work, and you [snorts] certainly love that number four for some reason. Okay, so let's just take a look at the final card in this incredibly unpredictable procedure. So, what did you bring? Oh, check that out. You You You finished with the joker. Okay, whoa. How did you do that? Well, what's over here? What did we essentially replace the joker with? Let's just take a look. Oh, the ace. Okay, maybe that's why we didn't see it. What about these cards here?
What's in this little packet? Any idea?
Uh let's Oh, check that out.
How in the world were you able to do that? We pulled off the ace first, and then your entire discard pile forms the remainder of a perfect ordering of ace through 10 of hearts. And that crazy joker ended up being the lone survivor.
That is amazing.
Okay, so how do you do this? Well, it's very easy, okay? So, what you do, there's just a tiny bit of setup, okay?
So, here we go. Uh so, you begin with this, okay? So, before you display the cards, so you do do this outside the view of the spectator. I suppose you could even do it in front of them, they won't know what you're doing, because you're going to show them the cards here. And they're going to look at the ordering of the cards and go, "Yeah, those are Those are mixed. Those are scrambled." So, that's exactly the order that I showed at the very beginning, okay?
And then, I said, "Well, since we saw them, why don't we go ahead and perform an over under over under, okay? A mange shuffle." Well, what that does is it un does the Klondike except for the fact that it reverses the order of all of the cards, okay?
And this is the precise ordering that we need before we begin this procedure, okay? So, this is perfect. You don't show this, right?
So, you've done the the mange, and then if you remember, from there, I said, "Well, let's set the joker on top."
And then, I said, "Well, we only need actually 10 cards. So, why don't we discard the bottom." So, we put the joker on top, discarded the bottom, and of course, the bottom is the ace, right?
So, sitting over there. And then, at that point, this procedure of random randomly cutting anywhere, and then, you know, discarding, and then pushing off piles of cards that add up to whatever this value is, here it's seven, and then stacking those from left to right, and then discarding the new top card, maybe over here, and then repeating that, you're guaranteed to finish exactly in the way that I did. And if you ever hit the joker in this process, just have the spectator cut again, and this will work perfectly every single time. So, thank you for watching, and take a look at other videos on the Absolute Math Magic channel.
