Sudoku Solving Tip - X Wing Technique

[ExtraStrongGeneral]

You sound like a poof....

Im not saying theres something wrong with being a poof...

Im just saying you sound like a poof...

[onzku]

i used to use the X WING technique like you, then i took an arrow in the knee.

[CGagnon5]

This is a pretty common sense sudoku technique.. Figured it out by myself a while ago I just didn't come up with a gay name for it.

[Diosukekun]

@CGagnon5 you must be a genius :)

[thadinininon]

@Diosukekun u must be fucking stupid as sht if u think hes a genius

[airasweetie]

lol the people who doesn´t like it, didn´t get it :)

[Caedyron]

@airasweetie

OR they got bored by the mindparalyzing slowness of the explanation.

[airasweetie]

@Caedyron you´re one of them who didn´t get it, right ;)?!!

[Caedyron]

@airasweetie

I was expecting that response. But no, I watched it, understood it, and *still* found it mindparalyzingly slow. Matter of personal opinion, don't take offense ;)

[airasweetie]

@Caedyron well then maybe you should respect thos who need it to be slow!! 

[PoopTruffles]

Very good instructions... but you could just cut off 2 minutes with the repetitive talking :o

[bikingskiing]

I think this explanation is very clear, and uses many examples. It is incredible how many people here are so crude and mean. The voice is great, and the tips useful. 

[sardamti]

stupid asshole... any dumbass will know dis.. y d fuck did u make dis video?? i thot u wer gonna giv some expert tips.. cocksucker!!!

[kyozpsycho]

the voice sounds like either a teen boy who hit puberty late, or an irish old woman

[MonsterSnowmobile]

Great, Great, GREAT! Video.

[RoC1909]

There are 6 douche bags who couldn't solve a EASY if there life depended on it. *rolls eyes Who the hell WOULDN'T like this video?!? It's one of the best explanations!

[lololokung]

Thank you so very much! Loud and Clear! Thank you again!

[ImyourbabyLA]

Thank you ... very very much. Instructions where well done!!!!!

[xmatch]

loved the explanation, loved the voice, loved the accent; however, it is difficult to comprehend. Thank you very much though.

[EffroyableMat]

Good against death stars too.

[SuperVJE]

ty, gj!

[GrimReaperNYC]

again look at first sudoku case, look at the first 3x3 box row, number 9 and 7 always in pairs. once we found which numbers are in pairs and which are the lose variable, easier to find the solution.

but this is just one method to solve it, you still need all the basis solving methods, like number elimination etc.

[GrimReaperNYC]

theres also another method solving insane sudoke by looking for number pattern in a 3x3 box collumn and or row, i.e. look at first sudoku case, first box collumn, 3 numbers always a lose variable, and the other 6 always in pairs, look at 3 and 9, int the first box collumn 3 and 9 always pair the third number is the lose variable, we know 2 and 7 are the lose variable, theres another lose number variable that is between 4 or 8.

[Disekshonal]

I watched some videos of national sudoku championships to see if they write down little candidate numbers and they do so raspberries at the people who say it seems like cheating or training wheels :-)

[Brenpict]

Thank you for the instructions. And never mind the accent. I'm Dutch. If you ever heard a Dutch person speaking English...

[xnick0]

The X-Wing name comes from a Star Wars ship! (google it)

[StarCraftiNator]

this should be intuitive. if its not for you then sudoku must be hell for you

[TheMagicPillow]

I'm to stupid to understand any of this. I'm giving up on sudoku.

[BijeloNW]

he speaks too slow so it's annoying but it is good for people who actually don't know english well.

[TheScheiss]

This is awful!!! So much blablabla for something you could do with just a simple quick inspection!

It makes Sudoku seem boring and hard, which it isn't.

[senselocke]

Why is it not an X-Wing at 5:10? There are other 7's in the ROWS of 2 and 5, but not other sevens in the COLUMNS of 2 and 7. Shouldn't we be able to eliminate the other 7's in rows 2 and 5?

[ImTheBatchMan]

@senselocke We weren't doing that variant. That's why.

[francoiskeulen]

@senselocke: I think you're right. The sevens form an X-wing indeed.

[francoiskeulen]

@senselocke: I think you're right. The sevens form an X-wing indeed.

[Guitarcrystal]

SO LET'S GO AHEAD AND ELIMINATE THE AIDS! LOL

[gshreyasprabhu]

@Glendale1901 You're so right...I am in total agreement with what you say

[mcrxfreakxofxnature]

wtf you're not supposed to write down all those little red number choices.

[Jade161588]

@mcrxfreakxofxnature If he hadn't written them down in this video, he wouldn't have been able to explain as thoroughly as he could have. The optional tiny numbers are used very often in explaining strategies.

[whocares8013]

Ok an addendum to add, I see now looking at the video why the x-wing is necessary I just simply have never called it that, and never thought of giving the maneuver a title as such, nor have I ever written little tiny numbers in the boxes to show what can go there, I simply hold them all in my head, till I find a profitable situation.

[whocares8013]

You do realize this is not how you are supposed to accomplish Sudoku right?

It's not cheating per se as someone noted simply because there aren't really rules explained out, but it's like riding your bike with training wheels. I mean you can do it but it's neither impressive nor proper. Sudoku is meant to be done logically, but with pure logic, not with little numbers to help you out. Every single filled in position is filled in only once by deduction.

[sora1995KH]

I think i can finally understand a little... yet column and row variations is a little bit confusing, i will check out more example though...

[jolly246]

Is that accent scottish or janpanese?

[Branman345]

@jolly246 its a scottish accent.

[LemonGames]

Why its not a x wing if there is the same number in the horizontally way, but vertically it is one? wouldnt it be the same because sudoku would be the same, even if you rotate it?

[koveras13]

@SudokuVideoTutorials I understood everything you said, ty for that! But I really couldn't find any x_wings in a hard sudoku. And i'm 100 % sure there weren't any. So the trick x-wing seems quite useless to me.

[Pdaevnlies]

Thank you! You explain things very well.

[xlaym]

ahaha 2:33

in either care, u end up with aids...

its not funny i know 0o

[ajblue97]

@xlaym  it is fukin funny haha xD

[jarvexx]

Writing down those possible numbers (red ones) is in my opinion like "cheating".

[uwsheart]

@jarvexx

its not cheating, marking down possible numbers for yourself helps you with the puzzle, and displays advanced techniques requiring logic

[HollowedDoll]

Damn I learned a lot! I was sooo bored solving easy sudoku puzzles..thanks for teaching me this technique! For sure I'm gonna be able to solve those puzzles in the newspapers xD

[crystlball09]

Why would anyone need a tutorial for this? Isn't it obvious.Though I didn't know this is called "X-Wing technique".

[nevets4ever]

Ok - this is what most of my hard Sudoku puzzles end up looking like - up to four possible # choices per cell and stuck. Will look for X-wings and continue ploughing forward. Thank you for the clear explaination of X-wings!

[Dinyctis]

Oh my God. Thank you for the straightforward video. A lot of the tutorial sites are not concise at all when explaining the X Wing.

[fxbear]

Out of all my attempts to grasp xwing and reading dozens of tutorials, this is the first time i've heard about the row or column needing to be clear of the candidate. People heard my half frustrated half releaved AH HA two miles away.

[GFoladi]

I won't trust this. If you don't write down the small possible numbers in boxes this can be really confusing. I'm pretty sure I've used X-wings before but this makes very little sense to me

[martosss1]

actually at 5:15 there really IS an X-wing, but it's in columns - in columns 2 and 7 the sevens are only in row 2 and 5, that is the same rule, but in columns... Thus here we have two X-wings, and both give us the same result.

[gsxy92]

in the 2nd part of example 3, why is it not an x-wing? if you apply x-wing in the vertical orientation instead of the horizontal orientation i can't see why you do not get an x-wing.

[renumeratedfrog]

Best explanation yet. Thanks a lot!

[AmishWebmaster]

Thank you. This guy covers the advanced techniques yet in an easier to understand way. You'll want to view this more than once to understand the what is and isn't an "x-wing."

[bassman7530]

I'm a bit confused: can someone tell me why it is ok to have the common number of the highlighted cells in the same column as the highlighted cells, but not in the same row?

[arfolc]

That was very helpful. Thank you very much.

[4444hash]

Thank you Very Much for your Tutorial! ^_^

[fishy124578]

lol at 3:30 eliminate the aids =D

[mrvlhs]

Great way to put it:

"Let's see some formations that look like x-wings but are not x-wings. For example this one, do you think it's an x-wing?"

Hmmm... you made me wonder for hours

[bezzangi]

WoW, Nice video, very helpful. thank you.

[Thymonico]

Dhaaarg! You sound like our last year's science teacher!

Teacher to class: "This is a plant. P-L-A-N-T, plant! It's green... Can you repeat after me, children, greeeeen..." 1. grade HIGH school!

Great technique, though! :D

[LumpyGenitals]

very annoying voice but good explanation

[1975markanthony]

I agree with the others, this is a good x wing tutorial.

[nihalb1064]

very clear explanation.

[carl6585]

Thank you very, very much! You give very clear instructions!!!

[adevil79]

thank you :)

[Timei]

Nice explanation
