Can you solve the river crossing riddle? - Lisa Winer

View full lesson: ed.ted.com/lessons/can-you-sol...
As a wildfire rages through the grasslands, three lions and three wildebeest flee for their lives. To escape the inferno, they must cross over to the left bank of a crocodile-infested river. Can you help them figure out how to get across on the one raft available without losing any lives? Lisa Winer shows how.

This is the frog and the scorpion in wildabeast and lions. In the end nobody wins. Once the lions were busy packing each other across the river all by themselves and everybody else was already on the safe side of the river they should have took off. Left the Lions by themselves.

My solution: tell the crocodiles to bring the boat back 😂😂

[@Pitazboras]

There is an additional valid option after 9 crossings (2 lions and 3 wildebeests on the left bank, one lion on the right bank). The video proposes to send a lion back on the 10th crossing but the equally valid option is to send a wildebeest back. In both cases just take both animals to the left bank on the 11th crossing.

[@n_nagpurkar]

Wouldn't the wildebeest get outnumbered if it returns?

[@Pitazboras]

​@@n_nagpurkar No. After 9 crossings we have 2L+3W on the left and 1L on the right. If we send a wildebeest back, we get 2L+2W on the left and 1L+1W on the right, so both sides have a balanced composition.

This is one of those riddles that isn't really hard to solve, it's just tedious. There aren't any tricks or parts you need to think hard on, it just takes a lot of route checking and elimination. The riddle asks "What's the FASTEST way to get everyone to the other side" but once you start looking at the choices at each step of the way, you realize there's only one way that works.

[@chriswebster24]

They have to help out their homies. They made a deal. Lions might eat wildebeests, but when they give someone their word they always honor it. Plus, they know if everyone gets across they will each have a whole wildebeest to themselves, and that beats having to share wildebeests. Would you want to eat 1/3 of a wildebeest, or 2/3 of 2 wildebeests, when you could eat a whole one? Of course not.

[@MikeHawk-bg5ss]

We had this riddle in middle school once, though it was slightly different. There were 3 things to keep track of. Goats, wolves and cabbages. Each group had 2 members. You needed to take all of them across a river but your boat could only carry 3 things and because you need to be on the boat to control it, only 2 things can be on it. Same rules as the video. If there are less cabbages then goats the goats will eat the cabbages. If there are less goats as wolves the wolves will eat the goats. It doesn't matter if the cabbages and the wolves are left together because the wolves won't eat them. This one is waaay harder

[@PickAPocky]

This seems to be much easier than the river crossing riddle. You can just take both of the goats and leave them on other side then go back to take both cabbages and leave them there (now there are 2 of both goats and cabbages on one side) and then go back again to get both wolves.

[@jimmyifyoustillthisiwillde1017]

I don't know if it would take longer but I had a separate idea that I think would work. One wildebeast would stay on the raft the whole time. First it would bring one of the other wildebeasts over, then go back and bring the third. Next trip it gets a lion (note although at this point it would be outnumbered, same for the next point, it wouldn't die because: raft. And although this is kind of a weak point in my version, I think, played right, it would work.). This puts two lions on one side and two wildebeasts and a lion on the other. The next trip evens them out, so still good. And on the final trip both the last wildebeast and lion get off, so still even. I know its not as good as the real answer, and has a lower success/survival rate, but it's what I came up with.

[@LucyWhiskers]

I think this solution is actually closer to what I came up with…it’s 2AM so I completely forgot my idea. But yours sounds similar and like it could work too😂

[@peppygrowlithe]

The problem here is that, the moment it brings that first wildebeast over, there's one remaining wildebeast surrounded by three lions and he gets gobbled up.

A better solution is for 2 wildebeest to go across on the first trip, leaving 1 wildebeest to be eaten by the lions who will then be killed by the forest fire, which will greatly increase the chances of the wildebeest genome continuing in a lion-free environment - survival of the fittest.

This is a classic Computer Science problem. We had to solve it with a program accepting 2 inputs. Number of Pairs of Lions/Wildebeast. And size of the Boat. 3,2 was the base problem. It had to calculate unique solutions. I did it over a weekend.

[@abbyskelley7099]

I already solved this before this video was created. PROFESSOR LAYTON YO.

[@gimcadiente1648]

Abby Skelley same

[@phanicandaslothatthedisco2596]

wee woo

[@porlQ]

Abby Skelley which game!? I wanna know plllllzzzzz.

[@abbyskelley7099]

porlQ Professor Layton and The Curious Village I think. It's hard to find the game so.. I would try and find a good ROM. Lol

[@carmen8462]

SAME

[@gopherdon3783]

by the time there finished thinking about who's going to be across the river the would already become medium rare

[@ScarletEmber64]

I've seen this one! It's actually in a professor layton game that I played (The Curious Village) It's one of the first riddles, it features wolves and chickens, but the rules remain the same

[@themonsterunderyourbed.7620]

I gotta say that is a *really* patient wildfire.

[@thomasdoyle6812]

A great tip for this solution is that the moves are symmetrical. This means that after the 6th move, you just mirror image the first 5 moves and get there without any thought whatsoever.

[@panadaol9373]

Lel, poor crocodiles. They didn't get a role in this riddle :(((

[@minishina6056]

Floralsasha yes they did. they prevented the Lions and wildabeast from swimming across. with out them this riddle wouldn't exist

[@panadaol9373]

Mini Shina true dat hwo stupid of me

[@connor863]

To increase the difficulty a bit, ask the people to find the solution (s) with the lowest number of the raft crossing the river/the lowest number it animals crossing the river (in terms of trips)

[@cialater6359]

I actually got this one omg I could cry I've watched so many of these videos

[@tina-yb4mr]

my uncle bet me 20 bucks that I couldn't do this... I did it and he never gave me my money😂

[@dwarfie24]

Lol cheapskate

[@andyaaayaaa]

LOL.

[@138shreyshekhar2]

[@the1whoplayz]

[@xanderpizza2759]

TheOneWhoPlays YES IM NOT ALONE

[@KerropiKirby]

TheOneWhoPlays Same lmao

[@porlQ]

TheOneWhoPlays Wait, u play prof Layton! Nice! What game was it in?

[@xanderpizza2759]

I think curious village

[@lenzfaraday4954]

porlQ

[@NeoSlith]

I tore up some paper and labeled them with Ls and Ws to better visualize the trips. I remember solving this sort of puzzle in a Professor Layton game.

[@gyroist]

We just did this riddle today at camp!

[@leegtstony8064]

Oh, really? Imagine that......

[@rasp-passiontea8525]

I already knew the answer,,,, I've done this thing multiple times in Poptropica 😌

[@CyanStarLight]

Tayah Hutchins ha me to

[@schtwo5179]

Oh the poor poor game, if only they decided not to wait a year to redo the whole game...

[@luthias592]

Tayah Hutchins SAMMEEE I REMEMBER THAT ISLAND IT TOOK ME SO LONG TO DO IT

[@suyu5241]

OMG SAMEEEE

[@skylander4882]

Can someone plz tell me which island that is

[@shadowplays2617]

There happens to be a 'random' raft :/

[@teamrhganimations3343]

Yeah how good point

[@imindo7337]

I think the tree falls and accidentally make a raft

[@s.d.966]

Those lions are intelligent. They did not lose any of their lion friend.

[@thegamingdoge9407]

yeah

[@grandmastercultistofben]

Pretty sure for legged animals with hooves and paws cant use an oar aswell

[@santoshgouda4765]

Thank you so much

[@danibilling9435]

Is there a way this could work with 4 or 5 lions and wildebeest? I would like to use this as an icebreaker game but will have 8 or 10 people.

[@Justifier925]

As far as I can tell, you would need them to be safe on the raft for 4 to work, including when a swap-over is happening. 5 I’m fairly sure needs a 3 man raft

[@BenandJessQT]

you mean the corn, sheep and wolf riddle?

[@karlandreiagapito4470]

Clarabelle Shepherd well similar but theres only two animals (three if you count the crocodiles

[@anthonytrinidad9949]

For me it was the cat, chicken and seed riddle.

[@Zabazoe]

for me it was sane humans and cannibals

[@lostlong62]

Its not exactly like that because the animals on the raft count towards the side they are on, unlike that riddle where if the farmer is watching then it wont count

[@matrixphijr]

I thought it was the pedophiles and small children riddle... Oh wait...

[@michaelchristian6096]

One of the few I can actually solve without getting a paper, but I did a riddle similar to this in a professor Layton game

[@zehahaha5630]

Michael Christian Yeah its the same one except you uave to count the turns

[@semicolon.advocate]

oh my god this is the first ted-ed riddle I've actually solved guess I just needed to get high first

[@User-mp4vq]

Ted-ed: What's the fastest way for all six animals to get across without the lions stopping for dinner Me: Easy, jump on the crocodiles

[@sharedaccount1736]

😂 true thats the best way

[@abdulmohsinnoorazlan9109]

This is very genius, thank you Ted Ed,

[@adityapatel6544]

My first thought was: "It's the circle of life!!!!!!!!!"

[@gobblerbaby1871]

The bridge riddle on steroids

[@DJTileTurnip]

Basically

[@eggboi4517]

gobblergot Except you have infinite time

[@spiritwind5888]

The real riddle is how animals are able to ride and control a raft

[@user-jl3cc2wu3y]

This was the first of two riddles I have actually solved, and there is no way im solving any more

[@ahmadjauhar4562]

Solving ted ed riddles boost your confidence level by 80%, until you watch another vsauce video

[@annulrsolformrkelse4023]

Wtf happenend to the face of the lions

I thought about this riddle when I was in 5th grade, and someone else in my class actually figured it out in about 5 minutes!

[@jelo135]

I like the simplistic artstyle
