Thanks for your humor. Sudoku wasn't my "thing". Two months ago I was RECOMMENDED on KZbin to watch a video of yours. I was curious and I knew I would never put this in my head but watched you video up to the end. My daily newspaper had a sudoku EASY LEVEL so i tried it. 4 odd hours to understand bu suddenly i got the hang of it and thanks to all your numerous tutorials i am able to get to medium level. Sometimes Easy level is DIFFICULT to solve. Now I've installed a Sudoku app and I try to solve many as possible in one hour. Visualize and brain work together. Thanks once again for your help.

[@georgesthibaudeau1533]

Delightful puzzle. For one who plays notation free, two things will set you quickly on to a good solving path. First: the 126 in row 1 must end up in the lower and middle rows of block 2 leaving a 358 triple in the upper portion of the grid is already highly restricted. SECOND you have an easy to find 45 pair in row 7, col 1+2 and hence, a 4 can now be placed in row 9, col 5, and the 13 pointing from row 7 will end up filling the two remaining cells of block 8, leaving a 286 triple in the upper row. The whole lower horizontal portion of the grid is now super restricted. The rest goes fairly well.

I was hoping this would truly be a hard one, but it's at most medium level in most books I've seen, especially Frank Longo's (or the LA Times). No hidden triples, X-wings, XY-wings, unique rectangles, turbot fish, hidden rectangles, etc., that one would expect to use in a difficult puzzle. In really hard ones, usually you come to a point where all candidates for each remaining cell have to be placed and analyzed, which for me, often requires a few sittings. But thanks for the patient and careful solving! Great course for beginners or intermediate solvers.

[@SudokuGuy]

Thanks George for your comments. I have found that most players would have had trouble with this puzzle. I would suggest that your comments refer not to difficult but diabolical puzzles. Uou are oviously an excellent player. Well done.

Good question Can't be 7 due to a 2/9 matching pair which I explain a few seconds later. Thanks for your comment.

Yes, but you only discovered the matching 2/9 pair after you had placed the seven. This suggests that you had simply remembered where the 7 went from having done this puzzle before.

Sudoku Hi Robin, A Big thanks for your tutorials. They are the best on KZbin. Here are my remarks: 1e. Could you please start the video with a full picture of the board ( or as an attachment in your comments ?). I can then import the sudoku start grid in the iPad app ( of Jason Linhart ) and try to solve it myself. 2e. Please do more of these type of video’s. I found it especially useful to see in your comment the technique you used and linked to the video # in which you introduced those. 3e.Credits to the video editor ( your daughter I presume ).

[@SudokuGuy]

Thanks Johan for your support, and encouragement. 1e All puzzles solved from the beginning to end have the whole board grid view. When using Jason's app I suggest you try solving first without using the hint button. My path taken could be different than his. It depends on what I see and when. 2e You are the first who has told me that you use my website links to go to specific techniques. 3e I do all my own editing and the music is my own composition. I am a musician. Have a great day and stay safe Robin

I like the red pen. Could you also use the black pen for the big numbers that you find, and only use the red pen for the little numbers? Great videos!

[@SudokuGuy]

Good idea Mracus. Better still use a different colour again for new big numbers. What do you think of this?

[@marcosreal11]

@@SudokuGuy That would be good too, and a bit of fun. Maybe use blue because it is close to black and then the smaller red numbers will contrast well. Edit: Even better, we can borrow an idea from the Cracking the Cryptic guys and notate the little numbers for blocks differently from the little numbers for rows and columns. Maybe use red for the little numbers for blocks and green for the little numbers for rows and columns. Leave all the big numbers black. Circle the matching pairs. If you have a rubber band, a small sponge*, and a paper towel you can make an instant eraser for your marker which will be like an eraser on the end of a pencil. Fold the paper towel a couple of times, then put the small sponge on the end of your pen and wrap the paper towel over it and the end of the pen. Fasten the paper towel to the end of the pen with the rubber band. Now you can use the top side if the pen to erase! * Old small headphone sponges would be perfect.

[@jaybrown9942]

That is just what I was wanting to know.

Here is your answer. You will see that there is a 2/9/ matching pair in cell 2 and 5 When you have a matching pair you cannot put any other small numbers in those cells because only 2 or 9 can go there. Se lesson 8

[@maryolmstead3183]

When you are finding matching pairs, how do you know they are the only two numbers that can go in those two slots unless you complete more of the puzzle? Expert puzzles have so few numbers it's hard to tell.

[@javabeanz8549]

@@maryolmstead3183 When you have two numbers than can only go in the same two cells of a box, they are a "locked pair", so no other candidates should be considered for those two cells. These are typically found when doing what Robin calls the "cross-meet" technique, he starts into that at 3:10 into this video. Basically, this comes down to two cells that only have the same two candidates that can only go in those two cells in the box. As you get into more advanced solving, there are triples, quads, etc. A triple is where you have three cells, that share the same three candidates ( sometimes, one of the cells only has two of the three ) so you can eliminate those three from any other cell in the box. If they are restricted to a row or a column, you can then use them to eliminate those candidates from other boxes in that row or column. Quads are much the same, but quite a bit harder to spot, and they won't be all in one row or column inside of a box. They COULD however be in a row or column across the whole puzzle.

479 nyt hard style triple whacks row #1 and the back of the puzzle is already completely snapped in 2. Rated 13 out of way over 100 possible in Duncan Solver. Was expecting something a little harder from that title. 10 minutes and out from that point and I'm no speed monster over here.. And as a more general request, solvable grid would always be welcomed, even for quick examples. I'll still watch the vod anyways :-).

Hi sir. I have a question. In 18:46 why does the 7 can't go to row 4 column 2? Hope you can answer my question. Cheers!

at 10:57 why should 9 go r9c9 ? couldnt be it go to r9c3? i love your channel btw. did you play on competition ?

[@user-cr4fc3nj3i]

Because at the last row, the row number 9, there are 2,4,5,6,7 and 8 already, meaning the only 3 cells left are 1,3 and 9. Look at r9c9, it cant be 1 or 3 because they already appeared in the same block.

See above.

In the bottom right box, how did you know where to place the 9. Could it also have gone in the cell two cells up

[@SudokuGuy]

In the bottom right hand corner there was a 66,9 matching pair. The 9 could not go where the 6 is otherwise there would be 2 9's in column 8 In the bottom row there was no other place it could gol the bottom had 1360 as the only numbers which could go ,because 1 and 3 cannot go in block 9 as they are already there in block 9. Hope this helps.

[@mattowensrees]

@@SudokuGuy Thanks but I still can't see the logic In the bottom right box, the only known numbers are 1 3 4 5 (not 1360 as you state above) The "possible" red numbers in the far right column in the box are 89, 8. and 9 So, from your diagram the 9 could go in either cell. The position is shown clearly at 10.44 in your video. The puzzle solves because putting 9 in the extreme right bottom cell happens to be correct but I don't see that it was a logical choice, Could you look at that again. I really benefit from your tutorials and want to understand where my logic on this is wrong

[@mattowensrees]

Got it now. By putting in 1 3 6 9 as possibles for the last row, (your reply explanation had 1 3 6 0 which initially confused me) I can put first the 6 then the 9 in that block. Sorry for not seeing that earlier

[@jamesgoacher1606]

You must realise by now that the ability to see something is inversely proportional to the distance away from it. Of course we saw the '6' :-).

In 10:55, why did u put a 9

[@SudokuGuy]

Because it is part of a matching pair 6/9/ the 6/9/ mactching pair is due to block 9 having a 1,3. Row 9 had 4 empty cells 1,3,6,9 were the possible numbers. Watch the video again in this area. Have fun and happy learning.
