Solving the IMPOSSIBLE Coin Puzzle !! Hexagon Puzzle with 6 Coins 

I tried to solve the puzzle using 6 coins but failed even after multiple tries.. Later I watched the solution still was not able to perform the solution live, I watched the solution from the video again and achieved the solution at last. Great explanation, great video, great contents. @logically yours, you rocked again.

Who else saw the thumbnail and thought that 'I can solve in 2 moves: 😂 It was challenging after 2 conditions but I was still able to make it. 😎

*Thumbnail:* What is taught in class *Video:* What they ask in exams

For me it was easier to do it backwards. There's only two steps you can do, and one is clearly a dead-end. And the rule is inverted, you can only move a coin if it's connected to two others.

A fantastic puzzle, indeed. To solve this, I tried solving it reversed, as the moves were much more limited. For example, the first move would be putting any of these vertices above two other vertices. If I call each vertex in clockwise order A, B, C, D, E, and F, respectively, then I would take A and move it. Moving it so that it only touches 1 coin (which wouldn't be illegal because this is being played in reverse) would not accomplish anything, as it spreads the general shape too thin. That leaves moving it so that it touch B and C or C and D as the only 2 options, and it makes the problem much easier to approach, for me anyway. If we move A so that it touches C and D, we run into a problem. From here, it's important to keep in mind that a legal coin move must start from a coin which touches 2 other coins. A legal move ends with 2 or more coins touching, so that means these reverse moves must start with that configuration. B and F cannot be legally moved, because they only touch 1 coin. Moving D is legal, but it will inevitably leave groups of two or more coins stranded. You cannot make a final move to complete this pattern. Moving C or E does not lead to any configurations where the puzzle could possibly be solved. This means moving A so that it touches C and D is not the correct move. We must move A so that it touches B and C. Moving A so that it touches B and C, we now have to make our second move. This means F is not allowed to be moved. C and D would be legal to move, but this would not lead to a solution. Moving one of these would result in 2 or more coins stranded from the general shape. There is no constructive way to move C that would lead to a solution. You could move D around the general shape so that it is touching B and F, but this leaves the only constructive move- Moving E, as an illegal move because E is only touching 1 coin. It would be pointless to move coin A, because any place where we could move it is a move we could have done for our first move. Moving A again would be a wasted move. This makes B the only coin that can be moved in a way that is constructive. Moving B so that it touches C, D, E, and F fills up a decent gap in the shape, so that is what I decided to try first. After moving B in such a way, we can notice that moving F so that it touches A, B, and C easily completes the puzzle. F is touching two other coins, so this is a legal move. This "unsolves" the puzzle. So then, I did the puzzle in reverse to check my work. Move F so it touches B and E, Move B so that it touches A and C, then move A so that it touches B and F. This is how I discovered this solution, and it seemed to have worked well!

It's one of those things that's much easier to solve when doing it than when thinking about it in your head.

I dont think that suffice the condition... On making *MOVE 2* your upper coin was not touched by 2 other coins(it was having a single touch of just right coin) until you made your *MOVE 3* ...Observations?

I found this very simple (did the same moves, but upside-down). Not sure why this would be consider hard/impossible. Given 3 moves you already know that you need to have no more than 2 missing slots in the final hex, so starting point is forced. Then you know it's symmetrical 6-way, so the only coins you need to consider is center, the one off the hexagon. Play it backwards and it's clear how to resolve it, as ONLY possible move is to take any of the 6 and place it to make a 'corner'. No need to try around here at all, as it's all forced on you.

Another solution is to move the two middle coins simultaneously so they both meet and complete the top part of the circle and then move the coin at the bottom far left to the right so it completes the circle on the bottom!

This was a brilliant puzzle

Great video bro! Happy that I could do it on my own,but nothing is the end,time for next puzzle lol!

Omg my first assumption is correct, i just move my phone to the right a little bit and i tried like this video. I thought it wasn't the answer cus every riddle here is used to have brilliant solutions and i ain't that person. 😊

At any point of time, every coin need not be touching at least two coins. The 'move' actually only consists of sliding the coins such that they touch two other coins after placement. The coins not being moved need not be touching two others.

I feel good about succeeding in less than a minute, phew ...

This is a brilliant and frustrating puzzle. I remember this puzzle from when I was young, but I forgot the solution and so I had a lot of fun and bewildered frustration solving it again. I don't remember if I gave up on it the first time, but this time I kept at it because I _knew_ there was a solution. To solve it, I eventually had to give up on thinking logically and just "brute force" the possible first moves. There's essentially only three possible coins to move first, and a very limited number of places to put them. The solution starts off illogically, moving a coin away from a final hexagon position. But then ... aha! It works.

That was solid. I figured it out by realizing many option ended up symmetrical. I worked through the possible moves by force, in a way. Considering symmetry, there are only 3 choices for a start move; one for each coin in the bottom row. Try 1 - move the acute corner first. Try 2, move the middle first. Try 3, move the obtuse corner first. I found it is possible to complete it in 4 moves when moving the middle coin first. Then eventually worked out to move the obtuse corner coin first.

Your videos never disappoint us.👍👍👍 keep it up.

As with others, thumbnail appeared easy, so I clicked to see what the catch was, but ended up not having a great idea of what to do other than only needing to fill 2 slots rather than 3. Good Puzzle, Great Explanation, Amazing video!

Your videos always includes thinking out of the box. Love your riddles very much.....❤️❤️❤️👍👍👍👍

Awesome puzzle!! I took 6 coins and solved, that was really interesting. Left top over upper raw, central on its place and complete hexagon. Neat

When I wasn't aware of the rules, I said to myself that I only needed 2 moves. After seeing the rules, my 2-move solution ended up breaking one of them... but I did figure out the correct 3-move solution after pausing the video with the rules clearly visible. I just wasn't sure it was correct without fully watching the video because I didn't know off the top of my head whether or not the second move in the 3-move solution would have broken the same rule that was being broken in the 2-move solution I thought of before seeing the rules. Also, I didn't read the video description until after watching the full video. If I had, I may not have gotten arrogant and thought it was possible in 2 moves in the first place. XD

Hi Mr L.Y actually a Hexagon only needed 2 moves 1st 2nd coin from the top row moves up on top of the 3rd coin.2nd the 1st coin from the lower row moves up on top of the 1st coin of the top row then form the Hexagon.

After rearranging coins for some time, I finally solved it. But wait! Do it again... ACK!!! I didn’t know how I did it! It took a little while longer, but I figured it out and remembered how I did it.

this is the first video ive actually solved after a long time hahaha

This was amazing!

there is also other way , in which first coin that is center could be move bt in this case ,it would be feel like we not making it hexagon bt at last it will be hexagon.... step 1: move center coin to the left side touching two coins 2nd step: move the coin up (that is just below of the coin placed by step 1) 3rd step: move the 1st disturbed coin to complete hexagon.... : )

I did it !!!!! There are total four possible solutions to solve this puzzle. This was very easy. Sir, thank you for sharing such a good puzzle.

Use a small weak magnet to move the central coin out. *DONE* Edit: by the way this is also *thinking outside the box* which he wants!

“Hello logical people “ is a very good opening greeting, well thought

I got the trick logically! And it matched with the solution! 👍🏽

I was able to solve the problem but in a different way. Your logic puzzles are the best 😊 Thanks for your problems so much! :)

That was a really good puzzle. I had to pull out actual coins to try instead of just visualizing. I was able to solve without seeing the solution by identifying the problems i was facing and coming up with solutions along the way. (At 2:21 in vid and writing this, so not sure if same solution) - first problem is making 3 moves means you need at least 3 of the original coins already in their spots, and this is only if all 3 moves build into the hexagon. If you need to remove a piece without putting into it's final place, then tou need to start with 4. - second problem is that you need to remove the "middle" piece of the hexagon before getting to 5 sides or you will not be able to move it without disturbing other pieces. - next problem I started encountering was building the 5th side of hexagon usually did not touch 2 pieces in mostly all arrangements I tried. So, I came up with the idea of "standing" a piece by moving a coin to leave a different coin only touching 1 piece. -this led me to starting to abandon the farthest out corner piece. Then removing the "middle" of my now forming hexagon, and moving that farthest out piece to complete the hexagon. - So, if the coins are numbered 1-3 from top left to right, and 4-6 from bottom left to right. Then, I came up with: * 1 moves to touch 2 and 3 * 2 moves to touch 4 and 5 * 4 moves to touch the 1 and 2 in a hexagon shape.

Good one ammar 👍, keep the good work. Took 5min to solve it

This puzzle was good just rule out the possibilities and you can get it It wasn't hard tbh it was manageable

No, it's just matter of two moves, just place first coin from second row and second coin on first row above first row of coins.......😎

I thought all coins will be touched with a minimum of two coins but in the second movement, the top coin touched with only one coin so I think there is a very impossible task to complete with a minimum of two touches in every 3 steps.

I got a slightly different solution in that I moved those last two coins simultaneously so that when their final position occurred, they would be touching each other, and each coin will be touching the second coin when they ended up in their final position.

Took me about 3-4 minutes to figure this. Really good puzzle

By moving only two ( 2 ) coins, One at right in top row and one at the middle of bottom row, place these two touching each other and one touching bottom left and other touching bottom right , we should get the desired configuration

It's such an amazing puzzle. Your videos never disappoint us.

Harder problems brother..... I liked this one.... Love you.... ♥️

I _almost_ failed it, gave up until luckily the trick clicked for me. I suspect it's the only solution as it's the exact same way as in the video.

Took me 10-15 mins. This puzzle had the right amount of difficulty.

General essence is this; to create required hexagon, you need, at some point, to have coin, which touches only one other coin. How could this be done, when you can slide the coin only to position, where it touches two other coins(„correct move“)? Well, this rule doesn´t prevent you from LEAVING one inaimate coin in solo touching position, by performing „correct move“. Hence your first move must be such, that leaves one of the coins in „single“ touching position (2:44 - most left green coin)

I got it in one move: right index on middle coin, left index on bottom left one. Move both coins at the same time competing the hexagon at once.

Actually touching the two coins diametrically opposite to each other and touching the two adjacent coin with third coin ( as picturised in the video) deceived the audience

There's a variant where the six coins start in a triangle, you have four moves, and you can't move the same coin twice.

Number coins on top row as 1,2,3 and bottom row as 4,5 and 6. Now hold three coins numbered 3, 5 and 6 with three fingers and push down also push left so that coins 3 and 5 touches coins 2 and 4. Hope there are no violations of rules.

I think I solved with a similar method but instead of moving first ball to touch 2 and 3. I imagined moving 6 to touch 5 and 4. Then moved 5 to touch 2 and 3. Then moved 3 to touch 6 and 5 making a hexagon

Woww.. good puzzle 👍👍

You should have included the rule that 2 coins cannot be moved at the same time. Otherwise, it would have been damn too easy, since we have 2 hands to move any 2 coins simultaneously.

Got question wrong...It says only the moved coin should touch 2 coins...For already placed coins, its not required to touch 2 coins

Great video

I did it but basically upside down to what you did :-) took me a second to realise it was the same as my solution :-)

Amazing Puzzle

As This is shown ,then we can understand, u should ask make a hexagon "with centers "of each coin.

I think in the first move one coin is touching only one coin where it should touch 2 according to the condition.

It's a most difficult puzzle i had ever solved. I took an hour but can't solved it even after seeing the solution.

Easy but nice puzzle! ☺️

I'm not joking!!! Before just opening this video I already make a hexagon. With just 3 moves!!!❤️

Brilliant..👌👌

I tried solving it just in my head but gave up after like two minutes. Cut out six little squares (gets the job done) got it first try, altho i already I knew what moves will surely result in failure so maybe i should have just tried a little longer

This was an easy one. I solved it in a few seconds.

Came across this puzzle in the Aubrey Maturin series of books where the ship's physician, Stephen Maturin, is also an intelligence agent and uses this as proof of his identification. Very neat!

Use two fingers to move the coins, and do it in two moves. First move the central coin and hold it aside. Next move the bottom left coin with the other finger. Now simultaneously move both the coins into their required positions on the hexagon. This satisfies all the rules. It isn't mentioned that the first move has to be completed before starting the second move.

Phew, that was kinda challenging. But i made it tho.

Amazing...

I can't believe I solved it visually!

Brilliant

It did this in 3 moves After trying 2 times , the third time I was able to do it.....

Omesh!

By seeing thumbnail,I thought that 2 moves were enough 😅😌

I got the solution in about 5 minutes, but I did it upside down, moving the bottom right coin instead of the top left coin.

I solved this in the past but forgot how. solved it again by trial and error.

I had a solution about moving more than one coin at a time because the rules didn't say anything about moving more than one at a time

This logic puzzle was so much tricky. After watching the whole video, I understood how much stupid I am !!😂 Thanks for the elegant solution 👍♥️ But, What's your nationality??

Solution: First view it sideways, then arrange the coins to a flower or 5 sided shape. From this point you will see that you will only use 3 moves to arrange it.

Love it x

Nice puzzle

2:55 the above coin is touching only one coin.. i thought that move was invalid...

Very nice.

I hope u listen me When you used your first move in the solution the left most coin was not touching 2 coins at 2:51 so plz clear my doubt

I save this in like 5 minutes. It was quite easy.

What is we just slide the two middle coins of both rows and view the arrangement through different orientation?🤔🤔

I did in slightly different method. It's almost the same but I started from different place.

Now I will try with my friends 😅😅😅

Got it easily. But I’m quite good at puzzles 🧩

very nice video.

1st comment

this is amazing! I tried a lot of times and still didnt get. The solution stumped me, it was so simple and great.

After 20 minutes finally I am able to solve it myself....(without seeing the answer)

I would add a rule: Only one coin can be moved at a time. Otherwise there are multiple solutions.

Easy I even solved with just looking at the video while scrolling through RU-vid in less than 1 min

I thought this was easy, I got it pretty quick

Yayyy i solved before watching solution 🥳🥳🥳

Hurray!!!!!.Got it correct in the first attempt 🤩🤩

Really it is tricky sir

Did the 1st one in 2 moves LOL edit: just saw the video, i had an illegal move sorry 😅

What it only took me 10 seconds!? 😂

This was very easy took about 10 seconds for method and few more for confirmation but in this video it is done from the other side🤣😂🤣😂🤣😂🤣😂
