I have built the most deadly obstacle course in the world, and my friend Mack here is attempting to complete it without falling 200 feet to the ground. Whenever you're ready, Mack. First jump, he's about to do it.

Oh my God, I'm so high up in the air. Look at how much that platform is shaking. We are currently hundreds of feet in the air.

Look at that. And this is just the first of many deadly, painful, absolutely insane obstacle courses Mack will face in this video. And if Mack completes all six of the obstacle courses coming up.

He wins $800,000. That looks insane. I could not do what he's doing right now.

Oh my God, that thing almost touched me. He might not even make it past the first level. Two more jumps.

Oh my God. This is the last jump. I don't know if I can jump that far.

And of course, I have to make it the hardest jump. There's double swinging hammers and it's the longest distance. You have this.

I don't know if I have it. Mack, 800 grand's on the line. This is going to be a short video, boys.

It's scary for me and I'm on the stable platform. Yes! Yeah!

Don't celebrate too early. That was the easiest of the six obstacle courses. Let's go to the next one.

Can't get harder than that. Actually, yes it can. Mack has to complete all six obstacle courses if he wants to walk away with $800,000.

Mack, are you ready? I don't know. The answer is no, because we're not hundreds of feet in the air yet.

We're going up. . .

? Welcome to level two. As I said before, this one is much harder.

Remove your blindfold. In front of you are two games you used to play as a child. Balance beam and monkey bars.

You just have to pick one of those and get to this side. Also take your harness off. No, no, no, no.

If for whatever reason he fails this obstacle course, he free falls 100 feet into a net, just like the first course. and his 800 grand will burn. Jimmy, you gotta chill out, bro.

- This is the second one. - What do you mean? Winning $800,000 isn't supposed to be easy.

God, dude. All right, it looks like he's choosing monkey bars. This is scary to watch him climb down.

Once he starts dangling on that first bar, he can't go back. Let's see if he locks in the monkey bars. No way.

800 grand on the line. Three. Don't look down.

There's no going back. Two. Oh my gosh!

Come on Mack! Oh, don't fall Please don't fall. Please don't fall.

You got it! Bro, this is crazy. I know it might be hard, but look, money.

Money's over here. Keep going. Oh, this one's way further.

Well, Mark, the further you go, the harder it gets. Oh, no. Oh my God.

Mack, you're almost halfway already. Think of all the other times you lost. Don't do that to yourself.

Mack, if you fall, we have to get a new contestant. Oh my gosh. All right, just a couple more.

All right. This one's a big one. It's a big one.

He's right here. Oh, this is a crazy shot. Please don't fall.

He's so close. Oh, my gosh! If you're wondering who my psychotic friend Mack is, he's actually a contestant from two previous challenge videos.

Even though he tragically lost both of them. He's been a massive crowd favorite, so I'm giving him one final chance to redeem himself and win this money once and for all. Welcome to level three.

What is this Jimmy? Potentially your worst nightmare. You see, so far in this video, the obstacle courses have all been about strength, which you're pretty good at.

But this level is going to test your brain. Press and hold this red button. Okay.

As you will see, a pattern is now popping up on the floor. Wait for this pattern to populate. To move on, you'll need to cross this floor.

Only stepping on the green tiles. And let go of the button. The catch is you'll be doing it completely from memory.

You have exactly 30 minutes to memorize the 44 tile pattern perfectly, and if you accidentally step on one red square, your money is rigged to explode. Here's a riot shield. Oh my gosh!

It'll protect you from the bomb. Start the timer. Go for it.

And he's off. The rain makes this so much more dramatic. Okay, the first step.

Oh. Stop. Don’t!

Tell us before you go. I do not need that. - That is not helpful to me.

- I didn't have my riot shield up. Mack, you sure you don't want to come back? No, I.

. . Bro, you can press the button as much as you want.

If you're not confident in your next step, you should really. Don't blow up your money. Almost five minutes have gone by.

- I don't need that. - And you're still at the start. I don't need that.

Mack, you've basically done a tile a minute so far. Okay, thanks Karl. - And there's more than 30 tiles.

- Okay. All right, here we go. - Okay.

- How confident are you? - Not - That that won't explode the money? I'm not confident.

- Okay. - And you're going to do it anyways? I'm kind of confident.

He's getting deranged. 23 minutes left. As you're questioning whether or not to take that step.

I want to remind you, this is your final chance to win this 800 grand. If you lose again, we're not bringing you back. Is it the forward one or what do you think?

Who are you asking Mack? - Jimmy, I don't know. - You want me to help you win my money?

It's not worth it. It's not worth it. At this point, Mack was navigating so far into the course that an individual attempt was costing him at least six minutes, no matter what he tried.

He continued to forget the very end of the pattern. It was down 3. 1, 2, 3, 4, 4, boom.

I think this is it. All right. This is uncharted territory.

I haven't gone this far. You have nine minutes. You can go back and check if you want.

I thought that was it. The only way I could go from here is forward. I think it's.

. . - Mack?

- Yes. Remember how you felt when you lost the 700 grand and 800 grand? Frequently, I think about that.

So for your sanity, you might want to go press the button one more time. But it's up to you. Oh, you're going back.

This is going to be my last time. Yeah. Okay.

Okay. Four. Four.

Right. Two. Four.

Four. Right two. Mack spent half his remaining time repeating the pattern over and over again, hoping that his decision to return to the start one last time wasn't for nothing.

But when Mack was finally confident enough to give it his last attempt. - Right, two. Okay, this is it.

- All right. He was faced with an extremely tight deadline. Under four minutes remain.

Under four. . .

Oh my God. Mack, I think it's time. Mute everybody out, bro.

It's just you. - Godspeed. - It's you and the tiles.

I can literally feel my heart pounding right now. This is so intense. He had 30 minutes to do this.

There is now less than three minutes. One wrong step and he loses another 800 grand. Four.

Four. Okay Four. Four.

This way. One. Two.

Three. This is where he got stuck last time. Oh my God.

Dude, it's coming down to the wire. I still got time. I still got time.

Oh, there's a high probability of an explosion coming up. All right, Mack, there's 10 seconds left. Wait, I don't know.

All right, all right. - Okay! You can just jump!

- Just jump. Jump, jump. There’s no time!

3! 2! Jump!

You did it! Yeah. Oh God I'm so happy he's not picking me up.

Oh you're right. Come here, come here buddy. No.

I'm being assaulted. And if Mack did step on a red tile. Anyways, let's head over to level four.

Come on. Now, this next level may look friendly, but I know for a fact it's going to obliterate you. This.

. . .

. . is level four.

And even though this course isn't in the sky, the obstacles you see here. . .

That's a lot . . .

are almost impossible to accomplish in your one and only attempt. So therefore you have two options. Tell me.

You can attempt to do this monster of an obstacle course, and if you fall in the water, lose everything. Or you can hold my Feastables chocolate bar and as long as you don't drop it, get as many attempts as you want. Feastables sounds like the plan.

Just don't let go that bar when you hit the water. What could go wrong? Oh, He literally would have lost in the first two steps.

So it's a good thing he's holding on to the greatest chocolate on earth. Yeah, we're going to be here all night. But I don't want to be.

So it's about dang time he got through the log roll. I just remembered, you're supposed to be wearing this helmet. Even though you don't need a helmet to know that Feastables is the best chocolate, I need you to wear one so you don't die holding my product on camera.

Whatever you do, don't drop that Feastables chocolate bar that's available in every single Walmart nationwide. You can also buy Feastables using YouTube shopping at the link below. What is this?

There's only one way to find out. Give it a try. It does not feel possible.

Bro, that gap is insane. What is going on? Mack, you want to get onto it.

Oh, okay. - Yeah. - Genius.

Yeah Mack. Mack seems to be struggling, so I'm going to show him how it's done. This is how it's done, Mack.

Did you know that Feastables chocolate comes in seven different flavors? Like my favorite one, almond. Jimmy I'm probably going to be joining you down there in a second.

He did it. I love Feastables chocolate. I'm definitely not taking a break right now to catch air.

Mack, the only thing standing between you and level five are these not big red balls. I called them that, so Wipeout wouldn't sue me. And these balls are so much harder than the rest of this level that we brought some other creators to test them out.

And let's just say they didn't do too hot. I'm never gonna die. Disregard everything he just did.

Yeah, I was thinking the same thing. So if you don't want your trilogy to end with balls, you better hold on to that Feastables bar. - Good luck.

- Three. Two. One.

God. All right. Try two.

Try three. Try four. Yes!

No! For literally hours. Mack just fell and fell.

Oh, yeah. And then he fell. We're going to be here until about four days from now.

No matter how hard he tried, he just couldn't grab on to that third ball. We've been going so long that the sun is literally starting to come up. This is your legacy.

You got it. Yes. Yes.

It literally took him three hours to get on that ball. Hold on! Don't drop that bar.

I'm not dropping the bar. He did it. Press the button before you drop the bar.

Let's go. Oh my gosh! Yeah!

Well. . .

You only have two more obstacle courses to finally win one of these videos. It's not getting harder than that. You can't lie to a man while you shake their hand.

Exactly. Which we're doing. That totally was the hardest one.

Just kidding. Mack is screwed. This next one is way harder.

Right this way, Mack. - Watch out! Watch your step.

- What? Where are we going? Yeah.

Forward! - I can't see. - Take the blindfold off.

Welcome to level five. What? What is this?

What's. What's going on? This level, you could probably tell we just built.

You see? Balance has been a trouble for you in past videos. You even declined the balance beam earlier in this video.

You weren't even able to get over one rolling log without falling and six times in a row. So now you'll have to cross not one, but three rolling logs and get all eight bags of money to the other side. And if you fall once, just once, you lose everything.

And before you do this challenge, I left out one final thing. You mind pulling this lever? What's going to happen when I pull the lever?

Just pull the lever. - There's no way. - We're doing this challenge.

. . - No!

no, no, no! - 200 feet up in the sky. Why?

It was perfectly fine. Not the sky. The feeling of the ground just disappearing like that.

I'm not gonna lie. I'm kind of scared. This is wild.

You will be not human if you weren't scared of it. Oh my gosh. We’re so high up!

You okay Mack? No. What's wrong?

I feel like I'm about to lose all this again, dude. I'm. .

. Just don't fall. This exact thing.

I couldn't even get across on the Wipeout course. I fell off of it like five times. And now there's three of them, and we're 200 feet in the sky.

In case I do fall. Thank you for giving me a third chance. I don't know if I've ever actually said thank you for giving me a third chance.

No, you just yelled at me a bunch. Yeah, I know. Well, you put me in the sky.

I don't know what I'm supposed to do. This is very sweet, but I have a feeling you're just stalling because you're afraid. Yeah.

Mack has lost $1. 5 million. Let's see if it becomes 2.

3 million. Whenever you're ready. There's only one thing I say in situations like this over and over again.

Godspeed. When he walks, the entire platform shakes. There it is.

There it is. I'm going to go for it. Right there, watch out.

Yes! And the final piece of the challenge that I haven't told Mack is as long as you've made it across. You're free to move on to the final obstacle course with whatever money you brought.

Or if you're feeling risky, you can come back for more. He didn't see that coming. This is a good bit.

What do you think I should do? No, bro, you go for it. You just did this.

You first tried both bags. Are you kidding me? You're coming back at 600 grand or not?

In the wise words of Karl. But you're doing this on your own accord. and if you fail, it's not.

. . No, I'm doing it because Karl told me to.

Karl Jacob's a celebrity. There he is. Oh, my God.

Oh, perfect. He has now made one full trip. I'm going to either sleep with a smile on my face tonight, or I won't sleep for three.

Let's go. And while Mack is hundreds of feet in the air risking 800 grand. I want to tell you about Cirkul.

The best part about Cirkul is these flavor cartridges which you just screw one on the top like this, which allows you to make your water tastes like whatever you want. You can also adjust the flavor intensity just by turning this dial. So if you set it to three, you'll get a little bit of flavor.

But Karl set it to nine now. Jimmy, that's a lot of flavor. That's a ton of flavor, which makes it easier to drink more water.

I have an idea. Karl! Oh.

That's it. I can't believe he's actually them. - That's four.

- I can't believe that worked. Dude, I just wish that there was new colored bottles. Cirkul actually has five new colored bottles available now.

Okay. Welcome back. See you.

If you want to give Cirkul a try, just go to your local Walmart right now because I convinced Cirkul to give their biggest drop ever for a limited time. All right, Karl, are you ready to send it again? Take your time.

I can't believe he's throwing these hundreds of feet in the air. Every one of these throws is literally 100 grand. Good stuff, man.

- Ready to finish it out? - Let's do this. Do you want to just stay over there and move on?

Or do you want to come back here? This is where things get risky. You can go over there with Karl and move on competing for only 600 K Or once again, grab the last $200,000 and risk it all.

Dude, you got this. All right. That's the Mack I know.

Okay. God dang it, dude. You made it across.

Why are you mad? Because I almost didn't make it across. He's back.

Bring on the money, baby. All right, let's bring it home. No hesitation.

Godspeed. And he's off. He's off.

Take a second, bro. You're good. This is a routine now.

Yes. - You ready to do this? - Oh, yeah.

- Let's bring it home, huh? - Yeah, dude. Think about your legs.

Don't fall. All right. Okay.

I'm coming to you. All right? Okay.

All the money's on the other side. Now he just has to cross without falling. Three.

Two. One. He did it.

Oh my God! Oh my God. Oh my God.

Come on. You thought I was done? We're not done yet, baby.

Come on! Don't celebrate yet. The last challenge is where you always lose.

I'm not messing this up again. And now it's time for the final challenge. Once again, Mack is blindfolded.

But you can probably tell by the noise. We are going back up. We are now at the top.

A couple more steps. A couple more steps. Take off your blindfold.

Witness the final challenge. This is by far the most insane obstacle course in this entire video. Oh, man.

Dude, that is that is. That is crazy. I wouldn't blame you if you're terrified at this course.

And because you've been through a lot and not only this video, but past videos including spiders, drowning, boulders, lasers, and of course, cookies. I have one out for you. You look right here.

You don't even know what I'm going to say yet. I know exactly what you're going to say. I'm not doing that thing.

In here is an umbrella cookie. So I'm going to give you a choice. You can attempt this umbrella cookie and if you complete it with 800 grand.

Or attempt this giant, monstrosity, physics defying obstacle course. And if you complete that, win 800 grand. This is a massive decision.

- Here's the cookie. - I'm not accepting it. At least not yet.

I've had actual, legitimate nightmares about this cookie. Oh, What was that, like a wop-wop ah? Kind of, that's sad.

But I guess, I mean, you did lose $1. 5 million to it. And if you lose right now, $2.

3 million and no other attempts in the future. He just threw it. Now that I know that.

All right, we won't be needing this bad boy. There is no turning back. Every single challenge in every video.

All boils down to this moment right now. Let's get it. To kick it off he has these two trapeze bars and then a yellow platform.

This only ends by you finishing or you falling. This is gonna be crazy. All right, we're off.

He did it! That's only going to get easier, right? Yeah.

Just don't look down. He looked down right when I said that. Here we go.

That is insane. By the way, Mack, did I tell you I brought your mom and dad out? They're down there watching right now.

- Go Mack. - Come on Mack. Mack, you can do this.

Oh my God. Oh, God. - Yes, yes.

- Mack! This next contraption is what I call the Wall of Death. Creative name.

Oh, boy. This one has a little bit of strategy. He can go up and down, or he can just come straight across right there.

And in case you forgot, put the camera down. We're still 200 feet in the air. Oh my God.

This is insane. Don't take your hand off. That's freaking me out.

Freaking you out? My hands are sweating just watching. Oh, I feel sick.

This makes me want to throw up. God, this handles are so small. Almost there.

Yes! - Mom, are you okay? - Yes.

My arms are so tired. Well, lucky for you, you still have, like, a quarter of a football field left, and you're going to need your strength for all of the remaining levels. This one is all about when you dismount the circle.

Basically, if you let go too early, you fall. Mack, you're shaking your arms out a lot. You better save your strength.

You know how it works. The hardest is still yet to come. Yes!

Yes! Now the giant swinging hammers. These things are massive.

And I see you brought my friend the balance beam back. If he gets hit, there's no shot he's. .

. - What are you doing? - What does it look like I'm doing?

Watch your head. Oh my God. That’s gotta be terrifying.

Yeah, Mack. Yeah! You're now at the final part of level six.

Now, listen, I know earlier you chose not to attempt the cookie. However, considering the history you have with these cookies, I just couldn't resist bringing them back one last time. I thought you already brought them back.

Why are you bringing it back twice? There's no need for that. I knew you were going to say no to that.

Anyone with a brain says no to that. - How do I get to that? - You just jump, How else did you get there?

And with every jump They get further and further apart. And if that wasn't hard enough, I made sure that each cookie gets exponentially smaller by the jump. And the only thing between each of them is a trapeze bar.

and 200 feet of untethered free fall. - You got this Mack. - You got it.

Four jumps. Let's see if Mack gets rich. Three.

Two. One. Oh God.

It was almost over right there. That was terrifying. One down, three more to go.

And Mack almost lost on the biggest cookie. Remember, the cookies get smaller with every jump. Don't let this be the moment where you repeat history.

Because it's going to be your final fall. As you can see, this bar is outside of Mack's reach, so he has to jump. And if he misses it midair, it's over and you go home with nothing.

. . One.

. . .

but shame Okay. He's swinging a lot. Don't swing for too long, Mack.

You're gonna need to save your strength for the umbrella. - Yes. - Mack!

Yes! There's some more. Does the crack of the star remind you of anything?

You're in the endgame now, Mack. These two cookies have broken you just as much as you have broken them. Fail here and the chance to be lifted from the darkness, will be gone forever.

Godspeed. He's off. - Yeah!

- Yes! - Go Mack. - Go Mack.

All right, we're on the final jump. Twice as far as the previous jump. Arguably the biggest hurdle in Mack's entire life.

The umbrella. It's do or die. He's either going to win 800 grand Or the saga ends and this all was for nothing.

Your family's rooting for you. Everyone at home is rooting for you Three. I can't breathe.

Two. One. I think.

. . Oh, he's about to jump.

He jumped Oh my gosh. He's so far away from that cookie. - I can't watch this.

- I can't breathe. Just so you know, there's 60s left, man. Wait.

What just happened? Oh, no. I actually don't know what to say.

I'm such an idiot, dude. Oh my God. I did that twice?

- Yes! - Yeah! Yeah!
