How to solve Sudoku Expert level fast

Play and solve Sudoku Expert or Hard level using just a simple strategy anyone can use. I forgot to mention that I was using the pencil option from the APP to write notes on it. Note also that I have fast forwarded some portions of the game video for the essence of time.

6:08 placing that 9 makes no sense (in row 6 column 7) that was pure luck.. There is no sufficient interaction between 2, 8, 5 and 9 to tell which goes where. There is no pair/triple/quad or any logic, 9 could have gone anywhere between the three cells at that point and all the other cells would've been satisfied with digits 2, 8 5, 4, 6 and 1

I'm glad I'm not the only one that was sitting there scratching my head over this... 🙃

[@davidgalaviz2004]

That expert level is far easier than the expert level on my app.

[@June-hq6hy]

Expert level! Cool. 😎

Thank you

6:12 I understand how you got that 9 there lmao

[@fredjones3570]

ez pzl mister...

[@exowye]

That same number auto check and auto highlight are not for experts in an expert level. It's actually a cheat. LOL

At 3.48 how did you knew that the row is already occupied?

[@howtoguy1503]

Bec the two blocks in the top right are the only possible places you can place 4

[@hardikparmar3890]

I too dint understand the placing of number 9 at 6.13

[@howtoguy1503]

Bec on the center right grid's middle rows, the possible numbers are only 2,8 and 2,5. So you would only have one option left where to place 9 based on the existing intersections

[@westonandelin4556]

@@howtoguy1503 I still don't see why 9 can't go there.

[@goodluk654]

@@howtoguy1503 2,8 and 2,5 were NOT the only possible digits at that point. What kind of technique is this? That was a lucky guess lol but you got away with it

[@deerparkleavers]

At 6:08 how did you know to place a 9?

[@howtoguy1503]

Check on the intersections. You will see that the 2 spots are the only ones left where you can place 9

[@lehopoiss]

@@howtoguy1503 6:13 that 9 doesn't make sense

[@jamesrmore]

@@howtoguy1503 i agree. Just because the other squares have either/or binary limitations they are not limited to only two possible numbers. At this point that square could also be a 1. The only places that can't be 9 in this square #6 are row 6 and column 9.
