I didn’t find this too hard, but this is maybe because I’m getting confident after learning through your videos! Thanks!

I have recently begun solving increasingly complicated Sudoku puzzles. I’ve tried learning new strategies, but I had learned nothing. All those how-to videos were by men. All I noticed was how fast they solved the problem. Rather than teaching me something, they seemed to simply be boasting. I have watched one of yours, and I was so successful! You enabled me to try some strategies I could actually understand! The puzzle was fun, challenging, and I fairly quickly solved it. Thank you for teaching and not boasting on your skills, (as the others did).

Thank you for the tips on the corner notes "Schnieder notes" and the app you recommended for inserting corner and center candidates. You have actually help me improve my sudoku game!

Thank you so much for giving these clear explanations in a calm voice and not too fast. Thanks to you, I am now able to progress past the medium level.

Actually I’m learning to solve the puzzles. I am solving medium level puzzle. But from this video I got confidence to solve hard level puzzles. Thank you so much Mam.

Nice solve. I am glad you went back and finished column 1. Nice job spotting the naked pairs and pointing pairs.

Your explanations were brilliant, thank you

This puzzle was nearly as easy as it can get for a NY Times Hard level. I started with locked in digits and went on identifying obvious pairs and further locked in digits to complete the puzzle without notations in 14 and a half minutes.

It was very informative. Thank you very much .

Thank you very nicely explained

This was so helpful. Thank you so much. I do the Sydney Morning Herald daily suduko . The easy version I think is equivalent to the NYT hard . I have a subscription to SMH. Not sure if you can access the Suduko ? May be worth trying ? They have an intermediate and hard suduko as well

Great video very informative , how do you get the arrows and circles ?

The combination of corner and center notation seems powerful. I notice you use center notation for the rows/cols and the corner notation for the blocks. Is that the rule? The puzzle is rated by NYT as hard but you didn't need to use any advanced methods (x-wing, swordfish etc.). I've solved a few of the hard NYT puzzles with the same logic you are using. This makes me wonder if there are cases where the advanced methods are essential.

How do you import a sudoku puzzle to f-puzzle Your videos are the best on explaining the different ways of solving sudoku puzzles

Very nice
