Sorry Mr Sudoku guy, at 28:35, you didn't notice there is a 9 in the cell R3C2 when you apply the locked numbers rule and eliminated the 9 in R1C9, please check again, thanks

[@SudokuGuy]

Yes you are right. My mistake, however I had done the puzzle before and knew that would not be a 9 My fault entirely for missing it. Thanks for your support, It turned to be OK in the end. Congratulations for noticing this.

[@SoRTs6233]

@@SudokuGuy Hi Robin, I too noticed you had 'locked number 9' but with a 9 in R3. I assumed it was because you had done the puzzle previously and so, knew it would be OK (I used to make the same mistake teaching Maths - it's very embarrassing!). I paused the video to find another way of doing this and found the hidden triple in Block 3. Now back on track. Great teaching!

[@nancyfarrell9624]

I can’t wait to see this.

that's great....you will learn a lot. Please tell your friends. Robin

[@fahadalanizi251]

Thank you, Professor Robin. I hope you will progress further. Is there a book you would recommend to a sudoku beginner?

[@SudokuGuy]

Yes, absolutely Find a book of very easy puzzles. they can be found in any good book store. (avoid the cheap ones) will shortz has a good book but make shrue it is at your level of knwledge.

Hey sudoku guy, in the description, instead of separating the minutes and seconds with a dot "." use this ":" because youtube will mark those time stamps on your video!!

[@SudokuGuy]

Hey Vitor. thanx for the tip. Can you show this to me in more detail.

[@gardenbee583]

Dear Robin Sir, now you are teaching Sudoku on the computer, which requires some skill as to which number to push whether it is a small number or a big one. I think it is a blessing in disguise for you not having your usual big board. It motivated you to use the computer and teach at the same time. Although I like the computer sudoku, I kind of prefer the board, but understand we have got to keep up with times. Board or no board you are an amazing teacher sir, God bless you with immense Health and Prosperity.😀🙏🙏❤️

[@SudokuGuy]

Hi Garden Bee, the reason I used the computer was that my famous white board was on a ship somewhere in the Pacific Ocean on its way to Australia where I now live. close to family. The ship was held up due to covid but I still have much to share so I used the computer for the time being.

[@gardenbee583]

@@SudokuGuy I understand that was the reason you switched to computer. I hope you get that board soon. Now I don’t mind learning Sudoku on the computer. Don’t know which program to use. It will be useful if you recommend the program you like. Wish you all the best, Sir.🙏

[@proomic7337]

Sorry I can't resist sharing. The 4-5 Matching pair in box 4 at 7:45 did so you could figure out where the 5 is in box 8. I think you've specifically covered the method in one of your other videos. Great job on this one though, Keep it up Robin.

[@shamabole7803]

Thanks to your early tutorials, I started to do Easy Sudokus with.. well, ease. I do the NYT games and used that to play. But when I tried the Medium difficulty, I was flummoxed. The gap between Easy and Medium seems rather dire. And Medium uses fewer filled in numbers than you typically start with. In fact, they start you off with 24 filled squares. Now, I am on your video tutorial # 16 but wanted to move ahead to see if it would help me with the NYT Medium Sudoku. The problem is that the examples you provide have built-in aids/scenarios that are not available at this level. Or it seems that way to me. Should I just keep plugging away from #16 onwards to pick up techniques that will help? Could you perchance show-and-tell a NYT Medium Sudoku with 24 numbers only so I could watch you work through it? Your feedback would be much appreciated.

[@SudokuGuy]

Hi Shama, I suggest you look at my tutorials as I do many medium puzzles from the beginning to end. This I am sure will help you to learn more techniques and tricks. Hang in there., with practice you will improve. Tutorial 83 is for advanced levels. Hope you learnt something. The difference between easy /medium and hard...there is no accurate rule to explain the difference. An many publications vary e.g. some use the number of initial numbers but this is not always good guideline.

[@shamabole7803]

@@SudokuGuy Okay. I assume you do walk us through puzzles with 24 or less numbers in that case. I look forward to it.

Hey Robin, I would be interested in your live streamings, but from Austria 🇦🇹 and we have time zone GMT+1, And I cannot find any such recordings on youtube .. so where are they ? Greetings John

[@SudokuGuy]

Sorry the answer is NO. All numbers have to be there due to logic. this tutorials is not a puzzle but a demonstration of a technique. See comments below video.

Wow! In this video you will use a program instead of your usual board. I like that

Although the puzzle worked out right, at time 28.28 in columb 2 row 3 there was a number 9 therfore the so called locked 9s in row 1 wasnt actually locked numbers. Was you correct , or was I.....

G'day Robin. Just a note on using the computer app. You can toggle between little and big numbers my pressing the spacebar (in case you weren't aware) and welcome to AU from one of your auzzie fans.

[@SudokuGuy]

G thanks mate. As you probably can get I am not used to using the computer for my lessons and tutorials because I am used to a whiteboard which is now on a ship somewhere between Canada and Australia. Thank you for your support

[@appylee9942]

The 9's in the upper left box were not the only 9's.So, you forced the single 9 into the 3rd top box which eliminated the 9 left out of the first left box. Isn't that just how a mistake just worked out by chance?

[@SudokuGuy]

Congratulations. You are right Yes I was lucky. However this was the situation. Before I filmed I had solved the puzzle without the small 9 because I had i(f you look at the puzzle) solved the locked 2 's in block 7 earlier and in so doing this put a big 2 into cel 2 row 3 eliminating the small 9. When I filmed I missed this move by mistake thus causing the little 9 to stay. Later I did this missed move.

[@appylee9942]

@@SudokuGuy Thank you. I admire how you are able to do so much of this on a board without mistakes almost all of the time.
