The Secret behind the the "Record 6" Puzzle

[@Mr.Puzzle]

From my point of view a variant with 10 rings would have been the better choice. Definitely too easy and no surprise in it. What do you think about it?

[@johnsjunk9157]

I liked the sound the puzzle made.

[@goininXIV]

Seems more rings would just result in more busywork, no added complexity.

[@Proctophile]

Love that puzzle. It's surprisingly tricky for how simple the design looks. I can only imagine how complicated future variations will be

[@g.tucker8682]

Given that each ring has two possible placements, the simplest strategy would be to step through possible combinations in binary counting fashion.

[@alphazero924]

Technically the two with two bumps have four possible orientations since they can be flipped or rotated

[@forbiddenera]

Divide and conquer.

[@forbiddenera]

6^4=1296 .. almost better would have been 4^6=4096

[@PaulMurrayCanberra]

Yup. Apply a sticky label to each ring to keep track.

[@Dargonhuman]

I feel like placing the innermost and outermost rings first and working your way in between might have saved some time as the offsets would become easier to identify and adjust faster - instead of getting all the way to the outer ring and not knowing which ring was wrong then doing trial and error on each piece (thus increasing the likelihood of misplacing even more rings in the process), you could troubleshoot two rings at once.

[@Mr.Puzzle]

Good point

[@EricPetersen2922]

Nice to see you again so soon 😃😃

[@cara9648]

Quite an interesting beginner puzzle!

[@DomPuzzles]

Nice puzzle, It is deceptively challenging despite its seemingly straightforward design.

[@arkbg22]

I would have enjoyed seeing a more systematic strategy where you attempt to cause the final notch to be rotated in the most clockwise position as possible then measure how much rotational change there is from each ring flip.

[@Patterntrick]

Disappointing only because Yuu Asaka's other puzzles have been so amazing. Still very cool.

[@BluishGreenPro]

Simple and elegant, I agree it’s a good beginner puzzle. Even if you tried to “brute force” it, you’d still need a way of keeping track of what you’ve done so far, which requires at least a little effort / planning.

[@chrisg6597]

There are only 2^6 (64) combinations to this puzzle, so a brute force binary style solve could easily be done in 10 minutes. 9.375S per try for all combinations.

[@Mr.Puzzle]

That's right, brute force solving is kind of boring though (from my pont of view). In the end it was possible to approach it also by trying the most logical combinations. I way I always try before using brute force.

[@NEMesis1413]

Some of the rings have 4 possible orientations - not sure if my math is correct, but I came up with 512 total possible combinations. Still a laughably low number for brute force solving.

[@NEMesis1413]

On a closer look, it looks like only 1 ring has the 4 possible orientations - which would make it 256 (I think) total combinations.. ?

[@ZandiTx13]

Chris Ramsey did this one and it's hard. It took a lot of trial and error.

[@markswishereatsstuff2500]

I'd like to see these rings scanned into a program and have a computer solve this.

[@curtishoffmann6956]

2 puzzles in one week? That's perplexing (multiplexing, but with cats) (cats purr. I slay me.) Love the puzzle - elegant, but challenging.

[@Mr.Puzzle]

Did you already get the Hanayama Triforce?

[@curtishoffmann6956]

@@Mr.Puzzle Yes. I put my reply in the comments of the Triforce video. I'll copy-paste them here, too. I found it at my local electronics superstore for 2800 yen (not including tax). At an exchange rate of 141 yen to the dollar, that's about $20, compared to $10 for the regular puzzles. I found it pretty easy. My first attempt (while eating a chocolate-chip scone at Starbucks) took about 10 minutes to take it apart and reassemble it again. The second try was under 5 minutes. The third took between 5 and 10 minutes because I'm still figuring out the details. It's fun and clever, maybe a 2 out of 5 for difficulty, but not worth $20. You're paying for the "Zelda" branding, and not for the puzzle itself.

[@kkbkkb5888]

Very interesting

[@kensmith8832]

This is a percent of error puzzle. Where the runout will prove to be a problem.

[@androidlogin3065]

Can it have more than one 'solution' ?

[@Mr.Puzzle]

Yes, it can be also upside down.

[@skyscraperfan]

As there are only two or four possible solutions for every ring, you can brute force them quite quickly.

New microphone? The audio seems odd, too much bass

[@Mr.Puzzle]

No, but the mic is sensitive to the distance. Especially when it's about bass. Not quite happy with it.

[@woncameron24]

2^7 combinations.

[@itsjustme6403]

It looks like a vinyl platte

[@Charlesb88]

You solved this puzzle in "record" time. It only took you 45 rotations per minute. 😃

[@Mr.Puzzle]

😁

[@willp2003]

Probably my least favourite Yuu puzzle, but I still enjoyed it. The newer ones are more difficult

[@Mr.Puzzle]

I'm missing the old ones that all contained and unexpected twist.

[@ELYESSS]

Backtracking is key.

[@Mr.Puzzle]

👍

[@Richard-ow3cj]

For once I beat you.. But it's not fun if you always lose. Thank you for your channel. Anytime you want to chess, message.

[@iiREYteoii]

Bro this one sucked with all respect

[@Mr.Puzzle]

Also not my favorite. But each video is a first time try.
