Tips on how to solve any sudoku puzzle

[prchecker]

i enjoyed this vid

[thejameskan]

really informative and interesting

[shelortrk]

would rather not spend 2646 hours solving a sudoku puzzle.

[scootsie119]

@shelortrk yea no shit. lmao solve what you can than start jotting the possibilities down.

[jeandavid54]

you can get a excel spreadsheet that fills automatically the cells as you enter the data

at jean.david.free.fr/sudoku-crib­le.xls

next you the rest

enjoy

[sailingsolar]

thanks for nothing.

[PoopTruffles]

Gay way to find numbers.

[twitchk1]

Have you seen KARENJI? It really is a true multi-player Sudoku game for iPhone and iPad. It’s AMAZING!! Finally, Sudoku has a real TWIST.

[niconikko]

Except if there is some kind of formula in excel that solves sudoku problems

[SudokueDotCom]

Why waste all this time creating an Excel spreadsheet when you can solve any Sudoku puzzle (note spelling PLEASE) using sudokue.com. Mode 2 will give you the same functionality shown here, Modes 3 and 4 are even more powerful. - try it now.

[zevlagable]

Sudoku is a logic game, use your brain!  Disregard techniques given by brainiacs

[siregarwisoka]

saya senang permainan angka sejenis gaya SUDOKU....DULU SAYA SUKA BELI TOGEL MALAYSIA DAN SINGAPURA MEMAINKAN ANGKA SUPAYA DAPAT 2 ANGKA ATAU 3 ANGKA TEBAK JALUR DAN TEBAK DUDUK ANGKA....HEBAT TAYANGAN SUDOKU INI.......MEWMBERI IPROVISASI DIRI

[fr3d420]

I am a beginner and I EVEN I can tell that this will definitely NOT solve every puzzle.

[kennethkrist]

If a Puzzle is that easy, I can solve it MUCH faster than this with only my head...

[SemiAquaticRhino]

why should we listen to them? they can't even spell puzzle correctly.

[BaXeD22]

This usually works for medium puzles or below, but harder puzzlessometimes require one of the advanced methods like X-Wing to get that one box, as usually in sudokus, most of it is very easy, its just the few key points where you need to think to get a breakthrough

[TheEgg185]

i stopped watching at "go to microsoft excel and make a grid like this"...uh...no... :|

[vgb42222]

i will stick with crosswords. suduko are boring cuz anyone who can see can solve them. now this made it even more boring.

[trextrent027]

whats up with box 4, you missed the 9, SCAM!

[dylanwenzlau]

eh you can find better descriptions than this, try something like a-how.com/archives/247 for a good description (with pictures!) of solving Sudokus

[immagodify]

[IBurnn]

I discovered this trick on my own when playing Sudoku, but as somebody else said, this method doesn't always solve the puzzle and extra thinking will be required. Some puzzles require extra "assumption" to solve, exercising your memory. Say you have an entry where you are stuck with only two possible choices. You assume that one is true and work to try and find a contradiction. Do this without writing any entries down or else you may forget which entries were and weren't correct.

[2wiirulez]

This technique would take so long it wouldn't even make sudoku fun. And it won't work for most of the puzzles you try to solve. I'm sticking to my better methods.

[322Bakerman]

I kinda do the same thing in my head....

[prusaks]

your trick for solving robiks cube would be taking a hammer and then putting it back together

[punkwarlord]

takes the fun out of it... might as well use the cheat on the back with all the numbers already filled in.. that would be faster...

[Racoonieboy]

I find using this method a waste of time. I could solve it much faster without using this method at all.

[gredangeo]

Was this an excel trick or something? wouldn't mind having that file and all it's fucked up formulas. :)

[OnkelJeppetto]

It works, but that's like using helping wheels :P

[drag0nblight]

Not new to me. I already had been solving level 5 and 6 sudoku puzzles using the Microsoft Excel. Well, you could really use the same technique using pencil on the Sudoku puzzle.

[nevets4ever]

This should be called reverse sudoku.

[zerogravity724]

How about a technique that doesn't require a computer. Im too lazy to do all of that. Pure brain power is more impressive.

[MrDaldagnuur]

Use -iseedeadpeople and warpten

[adolf512]

there is three methods to solve a suduko

- a number can only be in ONE spot in a row

- a number can only be in ONE spot in a box(fastest)

- this method(takes to mutch time)

but in harder sukokus (none of the methods work all the time)

- se if one or all numbers can´t be in a emty spots in a row or a box.

that is how really solve ANY suduku.

i prefer kakuro -> mutch harder.

[The619Champion]

thank you

[BowBeneathMyFeet]

I would call this method: how to take an eternity solving something that would have taken you five minutes. ^_^

[jesnol]

I took the same concept you did but one step farther. I made a program that automatically eliminates the repeat numbers up and down the columns, side to side the rows, and even the box it exits.

[allpurerandomstyle]

if you're THAT desperate to find a puzzel's solution, you'd better look at the end of the book and check the answer...

[bholyway]

You can use spell check by computer also. Try puzzle. It,s not spelled puzzel. The fun of Sudoku is to THINK.for yourself.

[rotterdam5]

thank you

[rotterdam5]

waaaaaaaaaaaaaaaaaaaaaaw

[xMainee]

this is way too much work, it's easier to solve it like you normal would do...

[ToolsnFire]

This and guitar hero.  Wow people,...come on.....

[Vabzy]

who wants to use artificial intel to solve sudoku.. how does that improve your math skills????

[NoLegsOnTheBed]

@Vabzy Well soduko doesn't improve your math skills either, it just improves your logical thinking.

[Vabzy]

@NoLegsOnTheBed sudoku is about astrology not math...the number nine is the perfect square which has important implications of knowing self. the truth is that solving sudoku should be purely of mind for mind creates and only mind is important. when u solve sudoku u r becoming a master of self.

[NoLegsOnTheBed]

@Vabzy then why did you say "who wants to use artificial intel to solve sudoku.. how does that improve your math skills???" and if you read what I wrote I never said sudoku was about math but logical thinking.

[Vabzy]

@NoLegsOnTheBed Oh so true.....I must have had the math notion from a previous argument still lingering in my mind. I apologise.

[NoLegsOnTheBed]

@Vabzy No problem:)

[Adrianlunnon]

oh o. I am not left with a single number in any box. what a waste of time this video is.

[columbus8myhw]

@Adrianlunnon Well sometimes u hav 2 think.A Sudoku's made of 9 rows columns and mini-grids and 81 cells.R there sum mini-grids where u r sure that a certain number must be in a certain row in the mini-grid, but u dont no what cell its in?Since that number *must* be in that row in the mini-grid, u can eliminate that number in all other cells in that row as a possibility. That helps too.

[labaizs]

doing this by hand or on computer is completeley useless and doesnt even require thinking..

[L1lzk]

i play it on my blackberry everyday and believe my it makes u think.

[NosirrahKaraneeum]

I tried this trick, it doesn't always work. If you have a hard puzzle, sometimes you won't have cells with only one possible number, instead you'll need to do some thinking.

[SudokuSecrets]

It would be far faster to just do it using logic than go through all that, sudoku is a game of thinking..

[TheSilverUchiha]

This seems like what you do anyway... only on a computer... which (to me) would just make it more time consuming anyway.

[inomeado]

idiot

[BSZanatsu]

To actualy wright out all of the numbers and then erase them would take to long. only do that later on when you cant find anything easaly.

[scotland7yard]

one of the weakest videos here in youtube

[jpGaiamundo]

that is the normally way to solve it...:S

[cogentfellow]

I know it's not nice to ridicule the Intellectually Disabled, so i'll just say Well Done...

[arthritismutilans]

You may think it is funny, but it raises an interesting point, Sudoku is essentially a 9 by 9 einstein puzzle, imagine 1is a person like John, 2, mable, 3, stephen

and in the columm, imagine

Row 1 is type of food, hamburgers=1, Fish = 2

Row 2 is type of transport, car=1, bicycle =2 etc.

This is actually the correct and universal, although long winded way of doing it

[jolazzzang]

duhhh..

[buskerbuoy]

Thats pretty much how you play the game anyway

[riccardofroz]

this instance never happends usually sudoku are more complex

[dragonxs123]

i fucking hate sudoku i have to do it for hw tho...

[metricprime]

whoa really? that's some bs shit...why the fuck would a math teacher use puzzles for hw...that's just lame. Unless the teacher taught you how...and is part of the curriculum, you should do it. Otherwise, you shouldn't....noob teacher can't think up better things for hw.

[jdhikl]

cool

[dzhitler]

bad idea

[trakaisjanka]

Now that is extra dumb.. What about puzzles, where there will never be such situation? This is called a 'naked single' - when only one candidate is left in a square, column or row. That's the easiest there is!

Try reading a bit.. There are far, far more complex situations and appropriate solutions (e.g. look up 'pairs', 'hidden triplets' or 'swordfish'..)

This is for 1st graders..

[linkinparkdiehardfan]

not bad.... only if a person totally doesnt know how to do it.....

[ateayeng0713]

you make me laugh...you think smart people would solve sudoku the way solved it? This is very impractical and stupid. Oh! by the way why have to go to excel?...FUCK!!!

[Declan1205]

i have my own method thank you very much!

[fastweirdo]

you dont need excel for this...you could just write the numbers very small in the corner of the box that fits the perameters...you are overcomplicating something very simple...technology makes us stuped

[nikobroo]

and how long time does that take??

good method, but I think it takes too long time and your brain cells aren't doing the work!

[cabaceda]

i prefer to reslve it by my self

[MacoCoffee]

damn thats impractical

[OBIT3]

Yes, this is a horrible tip! Not only is it very time-consuming, it won't even work for the harder puzzles - eventually you will get to a point where you don't have a box with a single number in it, and you will have to find another way to make progress.

[tedwik]

It's called the mark-up technique. However the technique itself solves nothing, you need to apply patterns (xy-wing, swordfish etc.) to solve it.

[Onlydreamin1959]

I did this and Norton Virus told me that somebody had hacked my computer (they caught it). I'm sure it's not the poster's fault. There are twits everywhere.

[lejink]

u put a grid in excel and norton said it was a virus? lol.. i think it has absolutely nothing to do with this video or what u were doing and more likely a coincidence in timing, maybe norton was doing a scan in the background. there is no excel grid virus lol

[Onlydreamin1959]

Norton was not doing a scan at the time. I set my scans for specific times. It took me a while to clean the mess up, though. I'm not sure what happned, but there was a virus.

[Onlydreamin1959]

By the way, I didn't put a grid into the vieo. I just watched it and did a bit of scanning. Ad Aware took care of the problem.

[rugal83]

O_O

[StefanHRasmussen]

lol, i would have finished 10 expert sudokus before i made the small numbers.. btw this is not a trick, that's the way you do it.. in your head!

[yo7273]

waste of time just solving it could be faster(if u can solve it).

[akaiceflowers]

And whats the point ?

[seewatchsee]

why don't you just use sudoku solver online

[Capnmax]

This is the most ridiculous technique I've ever seen!!!

[obscurereference7]

that's completely impractical

[luislinuxero]

PUZZEL? XD!

[waterchicken777]

This technique is so stupid...........

[HarshawJ]

sorry, that technique will not work all the time, even if you could go fast... there wil be plenty of times that you are left with two or three numbers in a cell and other methods will need to be explored...

[EnragedSavage90]

wow i bet i can finish faster by actually doing the puzzle and and not this method that would probably take maybe about 3 hrs.

[destroyjewsat420AM]

lets see... do i want to waste my time writing out 729 boxes? or can i just have some fun with the PUZZLE. THAT IS THE PROPER SPELLING OF "PUZZEL"

[clibanarii]

mparoufes

[MisterLovahLovah]

Pes mas esy re mastora.

[evi3359]

opa re maga, to piases esi to pouli ???? ama einai ksigato kai pes mas

[MisterLovahLovah]

......... milisa se esena ? -.-

[videostoyou]

In this day and age why don't idiots use a mic? The most annoying videos are the ones with text overlays. This video sucks.

[inthefade]

i agree that text in a video is obnoxious.

[ParadoxGeek]

Every sudoku in the world? How about those with unique rectangles? ;)

[lermamedrano]

u people are all gay!!! all ya doing is just correcting each other and making fun of. OH my Gosh you got to be dumb if you dont kow how to spell loser. you luser! Puzzel? Pozzul!

[eXDax]

OK, I just spent some time making the table like he said. There are times when I've played in the harder difficulties and I hit a point where I have to pick a number by chance because there's otherwise no way to work it out.

I can categorically say this doesn't work. All the things I could do with this I could already do myself and all the things I *couldn't* do myself I couldn't do with this either.

But don't dismiss it just because of his spelling. Even the best of us make mistakes...

[dontfencemein1979]

Yeah... um.... Did anyone catch that? They spelled it "PUZZEL"... I'm really going to listen to that genius!

[leb2nv1989]

lol yeh i noticed lmao

[perrofran]

Sudoku's purpose is train your logic mind, that trick is stupid

[PooPooPerson]

Stopped watching after :25... Complete garbage and a mockery to Sudoku.

[dpuflores]

you must be a looser if you think ima fill up each small 9 cells from 1 to 9

[259]

You must be a loser to not know how to spell loser.

[xsiv4c]

that method will not solve 5 and 6 star sudoku puzzles.

[hffin]

wtf

[GoldAK47]

gayest vid ever.. all i saw was colours changing LMAO

[headakerule]

yeah this was gay

[MrsDigiot]

dumb!

[Steversch]

wont solve everyone

[lovelybrutal]

it's stupid, it is actually only the most basic! Even if you do exactly like it, you could not fill all of the boat for lots of puzzle

[taarling]

easier just to solve the puzzle than do all this.

[LittleXRockStarX]

that's like CHEATING

i want to challenge myself!~~

[geebeeman1]

Too much work!!!

[colinminnema]

This is actually a flawless technique, but requires far too much time by hand

[enzeth]

ehm... this is so lame... =)

I'm trying to find someone to explain the swordfish... and this sayd "any" puzzle.. =)

[nolareaper]

this is pretty gay.

[AzNPride827]

What about trailing?

[Tonyguitarist7]

They spelled 'sudoku' S-U-D-O-K-O and 'puzzle' P-U-Z-Z-E-L. So, how good can this tutorial be, actually? It's supposed to help you solve a SUDOKU PUZZLE, not a SUDOKO PUZZEL!

[B3ttis]

too much time is need for this

[dfhwze]

this is just the basics though, you still need to search hard to find patterns like wings, fishies, cycles, sets

[dfhwze]

you have to use a system that allows you to check all avaible candidates left for each cell, if you want to use most of the solving methods for medium and hard sudokus, unless you are a genius of some kind

[DrtyWrm]

If you use a spreadsheet to figure it out, how does this develop your brains ability to analyze the puzzle, which was the basic point of the game or so I thought. Seems kind of like cheating, but hey i guess its an interesting method. Is it fun, solving them like that?
