Excellent. Thanks. I’m trying to move up from just Snyder solving and though I know a few of these more advanced techniques I struggle to know WHEN I should be looking for them. This is v helpful. Thanks.
I don’t get the logic behind why xy chains work. More specifically, why do bi values cells that share a value and see each other on the board allow you to link them together and continuously link them to other cells? In example one, when I tried to work backwards from the xy-chain between the 6-7 cell and the 6-1 cell, I checked what the values would be for each cell in the chain if either of those cells were the 6, and when the 6-7 cell was the 6, the chain didn’t work. Am I thinking about this wrong?
Possibly. The way I think about it is to start with the digit you are trying to eliminate (the 6 on this example) and look inside that first bivalue cell first (6-7). Then start working the chain with similar digits between cells and switching digits within the cells. Always end your last link within the last cell (1 to the 6). Another way to think about it is to say first cell is 6 and anything that sees is cannot be a 6. If it is not a 6, then work out all the values of the chain and you will see the last cell has to be a 6. Don’t put 6 in first cell and last cell to see what happens. Just use both values of the starting cell. Does that help?
@@SmartHobbies I don't think so. I have not seen too many of Clover's (or other setters puzzles). On your channel, do you have play lists of you solving particular setters creations?
@@andrewatherton316 I do not though that is a great idea. Instead I put setter names and all strategies I use in the description of each video. You can search for either of those on my RUclips home page.
Great question. I used Hodoku desktop app to do this video. It’s free to download and great for learning new Sudoku strategies. Check out this tutorial to learn more about it: ruclips.net/video/QCVOSevcYoI/видео.htmlsi=5lQdQZ1Yiq8tNK-4

Very well explained, finally got it, thank you!
Outstanding! I am so glad to hear that.

You are welcome. In my tutorials I strive to communicate when to apply strategies as much as how. I am glad you found those helpful. Happy solving!
@@SmartHobbies Cheers. What software are you using for your RUclips solves BTW?
@@mbroughton I use Hodoku. It’s available free online to download.
@@SmartHobbies Thanks for this. I can't believe how powerful it is. I also am surprised at how much I understand.
@@eugenetswong Great! Keep it up.

@@SmartHobbiesthat makes a little more sense, thanks
Isn't the X-Y Chain simply another name for X-Y Wing??
An XY-Wing is the shortest form of an XY-Chain. Anything longer than 3 cells is just an XY-Chain.
@@SmartHobbies ah thx
Example 2 Column 5: 769 / 58
Example 3 : A Nice continuous loop in block 5 too?
Yes it is! Thank you for pointing that out. Have you solved any of Clover’s other puzzles?
@@SmartHobbies I don't think so. I have not seen too many of Clover's (or other setters puzzles).

What’s the name of the app you are using? Thanks.

Found your channel via Mother G & Redd!tt. I'll have to watch this several times for it to sink in.
Welcome to the channel, and thank you so much for watching. I hope Sudoku as fun and challenging as I do.
@@SmartHobbies So far. I think I'll have to review the intermediate playlist to see what else I might of been missing.
@@brucewayne2091 Awesome.
