#sudokuguy #sudoku #learn sudoku www.sudokuguy.com
A fun, step-by-step video on how to solve a sudoku puzzle from the beginning to the end.
Many procedures, tricks and techniques are used, plus a couple of rules.
VERY IMPORATNT.... Some subscribers have told me they are not getting notification of when I upload a new video. KZbin has been working on this issue. I am pleased to inform all my subscribers that if you click on the bell at the right side of the red subscription button, you should receive a notification from KZbin that I will be uploading something new on a particular day and time.
I will only be putting up notifications once or twice a month.
One advantage of doing this on my channel is that when I premier a new video you have the opportunity to chat with me as well if you wish.
Thanks to all of you for your comments underneath the videos.
Also, if you wish to contact me, go to my web site www.sudokuguy.com and send an email to [e-mail]

7:50 could someone explain to me how he decided that the small fours could only go where he put them? Why couldn't one go in the top middle square of the middle block, or the bottom left square of the top block?

I wondered the same! The middle block is part of a matching pair (6+8) but then bottom left square still seems a possibility.

[@unclemikeb]

Well done kind sir. I chuckled a bit when you were doing this puzzle. I had accidentally discovered the exclusion rule. I was calling it the "odd man out" because I didn't remember you mentioning rule of exclusion, or my feeble brain didn't comprehend it. Such as when you had the 2-8, 2-8 and the 2-9. Rule of exclusion meant the 2 of the 2-9 was impossible and therefore could be removed and the 9 put in the box

7:49 - 7:55 Why was 4 placed in R1 & R2, C1 of BLOCK 5? Why was R1C2 discarded? Thanks a bunch! Anybody can pitch in to help ;) EDIT: Is it because we were only solving for the 4th column of the overall matrix? EDIT 02: I understand the reason; it's because of conjugate 7 in R3 of Block 5.

[@SudokuGuy]

See comments under my video.

[@Thfeyhvfdetyhbvcd]

The 4 at 7:50! I GET IT!!! This genius was thinking several steps ahead and had already realized that a 7 was going to end up in row three, column 4. He just didn’t mention it. Can’t do two things at once. In the video at 8:50, you’ll see where this happens at 9:25. But he had already solved this in his mind minutes earlier! If he had actually shown this first, a lot of questions would have been avoided. Wish I was that smart!!!

Interesting. I have never of that rule. Sorry I can't help you on this one. Usually I have no problems but you have stumped me. If you could show me where this comes from I may be able to help.

[@CL_G]

@@SudokuGuy Hi thanks for replying back. In its base form it means that there is only one solution to a puzzle. But sometimes on the harder puzzles, I find myself stumped over some of the twin pairs. They explain the rule in sudokuprimer.com/ambiguity-rule.php and there is another you tuber by the name of Harold Nolte who shows them. I just prefer the method of how you teach because it is very slow and you show your notes of possible numbers in a cell.

HEY SIR I AM ANVESHA NOW I CAN ALSO DO SUDOKU YOU ARE THE BEST

[@SudokuGuy]

You are on your way to enjoy sudoku.

[@sprocket454]

I'm always interested in other techniques. My own method uses the same process on every sudoku, unless quite hard, and uses no pencil marks. I simply start at the top row and memorize all missing numbers in that row. I then test each empty spot moving left to right to see if only of those numbers is possible. After that I test the missing numbers in the row one by one to see if they only work in one position. Then I go on to all the other rows repeating the process. Once I have gone through all the rows once, I repeat the same process with the columns. After that, I repeat the process for the nine cells. At this point I will have never backtracked or changed my focus. I've done one single process from beginning to end. At this point I will have many numbers filled in, possibly completing the puzzle, but if not, I just start back at the top and repeat the entire process again and again until I have solved or can't fill any more numbers with this process. Since there are no pencil marks, I then find matching pairs, and use various techniques to see if they force numbers to be locked into position. Beyond that It gets very hard to visualize and as a last resort I will use pencil marks. Most often I can solve without them though.

[@SudokuGuy]

Well done. If it works for you that's great sprocket. I suggest you look at tutorial 79, 82 and 83

[@alantorrance6153]

I had the same question!

[@mnbabariya43]

Sir,can it be predicated that after up to what stage we can be sure that now the puzzle will certainly be FULFILLED...? As I started filling hard puzzles, Thanking you Hoping will get positive reply.. Mahendrakumar Dubai

[@SudokuGuy]

Yes it will Mn. Lots depend on the puzzle and what techniques you know and what you spot and when. Most puzzles have 2 sections. The first section is where you buld up enough numbers by using a procedure and then spotting a technique. After you have solved it then the rest of the puzzle falls into place. Watch my tutorial #64 which is being uploaded in July. It shows that once you have solved numbers by using a technique such as spotting a pattern, then the rest of the puzzle is easily completed

[@BelieveB23]

Love you videos. I have a question dear sir. I have formed a habit in my short time of playing Sudoku (thanks to you...for playing the game not my habit) I start with 1 and go through 9. Info through once and then a 2nd time to make sure I am accounting for all the implications from the previous solves. After that I begin looking for the houses that contain the fewest empty spots, patterns etc. I have noticed NO ONE else does this. At least not any of the good players teaching tutorials on KZbin. Lol It seems most people actually keep it pretty random in terms of just looking for things that stand out. You use a Colombo section, Row section technique, ALTHOUGH I suspect you may not use so so religiously when solving puzzles outside a tutorial. I feel like my technique may affect my interpretation of the board, or limit what I see based on routine and expectations. Or does it not matter?

[@SudokuGuy]

If it works that's great. The time may come where you may have to adjust. Have fun

[@truthseeker4690]

Benjamin Henry I thought everyone solved these puzzles like that. Start with the 1's thru to the 9's. Then repeat the cycle unless something obvious or easy comes along. Doing it randomly for me causes more confusion and it takes longer. You end up missing critical solves. Also, when I complete all of a certain number I indicate that by putting a dot to the left of the big box. 1 at the top down to 9 at the bottom. That way I don't waste time searching for numbers I've already finished. I guess it's whatever works best for everyone.

[@semperfi1818]

Hello, at the 7:27 mark, why can't a 4 go in the middle? I don't see anything stopping it from going in the very top middle box. Can someone help with that in simple terms please?

[@SudokuGuy]

See my comments under the video. Yes I have to confess. I jumped ahead knowing that the 4 would eventually have to go there. You are irght in questioning this. Robin

[@highdefp-rm7zg]

Another great lesson :) although many people asked the 7:50 question about the four and there is no answer to this despite looking through the comments. I guess it was a mistake that got lucky.

Sorry Danial , I jumped ahead knowing the next section. My fault. See the comments below. thanks for your support.

[@gabrielpoarch635]

At 13:18 using the rule of exclusion, you could put a nine into the 4th cell down in the 9th column, then you could solve the 3x3 in the right block of the middle row

[@SudokuGuy]

Yes you could, but you must be able to explain why you put the 9 there. The rule of exclusion you mention does not help you get that 9. In the end it does become a 9 but due to other factors.

[@gabrielpoarch635]

@@SudokuGuy it's the only place the 9 could go. All of the other cells in that column have 9's in there row. The only one that doesn't have a 9 is the 4th cell down.

[@gabrielpoarch635]

@@SudokuGuy sorry I must be confusing the rule of exclusion with another rule. I just noticed the nine could only go in the 4th cell down because all of the other cells in the column had nine's in their rows

[@derdavinator6033]

at 7:48 how do you exclude the 4 from going in the middle top position of the middle block? could someone tell me that would be much apreciated! In the end it works out because the 7 enters the spot above but is there a technique i dont know?

At around 8:10 he deduced that the 4 could only be in D4 or E4 and I’m not sure why. At that point in the puzzle I don’t see any reason why the 4 couldn’t be in D5 as well. Any insight would be most appreciated

@Sudoku Guy I totally understand. It was my fault, I clicked on your video for the first time. At my level l was looking for a difficult puzzle and a strategy like X-Wing. I've always used my logic, and never have read or watched video on even how to play. I assumed in ignorance that difficult, or hard meant difficult as I knew. That was foolish. You are a wonderful teacher, being intelligent enough to make the complex simple so people can learn. You have that caring spirit of one who really wants his students to learn. I'm sure you were a favorite of many, many students. You held my attention just with the way you presented yourself and your joy about the subject matter, and excitement that people will learn. This world badly needs teachers like you! God bless you, and thank you for taking the time to respond.😊 Your video came up first, so I knew you were the most popular. I certainly wasn't expecting a response. I will definitely look at more of your videos. God speed 🙏

[@SudokuGuy]

Thankyou muchly for your kind response. I hope you look at my videos as you will learn much.

[@ridefast0]

I wonder if there are some Sudokus with only one path right through to the solution? I see lots where there are a number of choices for the next step at one stage or another. I think a 'one-path' Sudoku might seem hard even if the steps are easy.

[@SudokuGuy]

There are many paths you can take to solve. It depends on what you see and know and when you spot it.

[@timdolan4591]

Good Stuff - I stumbled at 7:50, why can't a Little4 go in Block5Cell2 (5,2)? I see in B4 that c7 and c8 own the 4(and 9), and in B5cells5 and 6(5,5,6) must be a 6 or 8. But I can't see why 5,2 can't have a L4. I don't dispute the solved end result but I just can't see why not.

[@SudokuGuy]

Hi Tim, You are the first to notice this. You are right. I jumped ahead and should have not done so. No excuse.

[@lilicronje9787]

Not to worry, even a blind squirrel has the right time two times a day. Fwiw, I took your puzzle and tried to solve it my particular way. It took me way more than 30 minutes. When I came to the fork in the road I must’ve gone the other way. Always enjoy your videos 👍👍

When you put in the matching 4/9 pair in the center box, didn't you neglect the possibility of a 4 in column 5 row 4? And then I got confused when shortly there after you violated your notation and put 3 tentative 4's and 3 tentative 9's, not in the same row (or column) in the middle right box.
