Yeah, many of the advanced techniques take patience. For Hidden Pairs I have a new technique I use to find them. In the software, I quickly alternate between highlighting the suspected candidates participating in the pair. It creates a kind of animation where you can see for particular house if you have a Hidden Pair.
OMG, I had so much trouble spotting Hidden Pairs. Usually when I got stuck on a sudoku, it would be pointed out to me that I missed a hidden pair and It would happen quite often. I'm so glad I found your video. Because I finally get what i need to do now and take it one candidate at the time. Thank you so much for making this video!
Awesome!! Hidden Pairs can be tricky. I think with Hidden Pairs it just takes practice. If you can run Hodoku, you can use it's Learning Mode to search for Hidden Pairs repeatedly until you master them. I did a whole video on Hodoku's Learning Mode here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jPssW_W3iH8.html Make sure you do the practice exercises. When you do the same technique 10 times in a row you really master it. Just seeing it every now and then takes a really long time to master a technique.
@@dxsudokuchannel I do agree, it can be harder to learn if you don't run into the problem often. I've not heard about Hodoku before and I will check out your video on it soon. I appreciate the suggestion and help! :D
for me it's still unclear whether I have to check for box criterias when I found a hidden pair in the same box and what I may remove then. For example: I find a hidden pair for the last column in the right corner that is fully in the box. The hidden Pair is (2,9) there. Is it a problem that other (2s) or (9s) are in the same box not interfering with the column? If not, may I remove the digits from those 2 cells in the column but also from the other cells those (2s) and (9s) in the same box being around? I certainly know that when I find a naked pair in a box that I can remove these numbers without any doubt from all other cells in that box, but this is still uncovered here and would be so useful to know.... That's why I find this video as many others way too vague. You need to explain stuff with a focus on special features, limitations and stuff, if you really want to make them more successful than the others. Too many feel like university lectures where people either want you to make the brain processes yourself to earn the degree or people lacking common sense on having empathy what people don't understand.
Sorry my explanation is not clearer. For many of the techniques, the only way I was able to master them was by using Hodoku's Learning Mode. With Hodoku's Learning Mode, it solves the puzzle to the point where the very next technique to do is the one you are trying to learn. The beauty and benefit of this is when you do Learning Mode 10 times in a row not only to master the technique but you have insights because you've seen so many flavors of the same technique. See video #24 on this topic. Hidden pairs are tricky to find. But it is important you understand the concept of what is a house in Sudoku. For a Hidden Pair to occur, there must only be only two pencil marks for each of the two numbers in the house. If there are are one it's a Hidden Single. And if there are more than two pencil marks, then the number can't be part of a Hidden Pair. Take a look at my #40 video titled Beginner's Guide. I explain more concepts which may help you. Also, there's another attempt at explaining what is a Hidden Pair and how to find them. Again, when I get feedback like yours, I try to improve my explanations. Also, my book has a pretty good explanation of Hidden Pairs because the person editing my book made me rewrite it until it made sense to her and she doesn't play Sudoku.
0:22 Hidden Pair: Examine this row. These two squares are the only squares that can contain 8 and 9 in this row. Therefore, the other notes in these squares can be erased.
Hi, no problem. When I had an iPhone I used Sudoku Joy. Here's a tutorial I did on Sudoku Joy: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ghSXRAXb388.html Now I have an Android phone so I use this program: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1lj7WI9Tcsw.html Both programs have the ability to use your phone's camera to scan a puzzle into the program. For my PC I use Hodoku, here's the tutorial I did on Hodoku: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--fTUFJajhSs.html Hodoku is my favorite and the one I use for my videos. Hodoku has this really great feature "Learning Mode". With Hodoku's Learning Mode you can really master playing Sudoku. Here's a video I did on using Hodoku's Learning Mode: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jPssW_W3iH8.html Let me know if there's anything else I can do to help you.
Some of my earlier videos I had mic issues and software issue. The videos got better over time. Plus I get a better mic. Try this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eP9fzCB0j5E.html
@@visionquestgolf736 This one has a good example of a Hidden Pair in it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6WnFkrUt_10.html My later videos are generally better. There's lots of skills involved in doing these videos.
@@nesse40 Good question. Think of it this way. For the two cells R8C3 and R8C5 the 1 must go in one of these two cells. And the 3 must go in one of these two cells. If the 1 is in R8C3 then the 3 is in R8C5. And if the 1 is in R8C5 then the 3 is in R8C3. There is no room left in the two cells for a possible 2 value to be placed. This is why it is eliminated.
