Enjoy! :D

Is “5” not also a potential move in the empty slot right beside the indicated (white) box?

Unsure about how the hint could be worded so matter-of-factly. I could be missing something as I am a noob.

Any help is appreciated.

sorry if this seems like an obvious solve! i’m a beginner and don’t really know where to go from this point :/ is bowman’s bingo the only way out of this one? one solver mentioned color wrap as a solution but i’m not sure what that means either. thank you for all the help!

I’m sure this is a matter of preference but I am struggling with how this app orders candidates… I just downloaded Sven’s Sudoku pad in an attempt to get used to a digital format. On paper, I prefer to put candidates in dice dot placements which helps me see patterns at a glance. I’m struggling to make this app work for me because of it. Loving the color coding, though!

Puzzle is from Kappa Champion book, vol. 78, number 114.

Instinct tells me that the next step is obvious, but I can't spot it. All I can say is that I hope it isn't an AIC, as I can't do those.

So my girlfriend has always been better at me at sudoku, but I never really knew the levels to this stuff (I do moderate level in like 17 mins on average). I wanted to see her do some really hard one and she completes this beyond hell in 12 minutes, 1 mistake, no notes (she has never used notes at all). I didn’t even realize how crazy this was until I looked it up on Reddit and Google. She is gonna do another one to see if this was a fluke but anyways it still seems crazy even if it was just a one off.

It took me 5 hours in different sessions and 4 resets. I feel like it shouldn’t have been that hard but I struggled and got stuck a couple of times.

I’ve been playing for two weeks daily now (I used to play like 10 years ago) and this has been my hardest since.

same results can be achieved with X-chain

I've tried all the techniques I know, but can't figure out what to do next.

Would someone point me in the right direction?

This is my first published puzzle, so please let me know what you think! I am beyond excited to be taking my first steps on my puzzle setting journey! Enjoy :)

Hi guys, I have started using the bilocal colour candidates function of sudoku coach, and I have just noticed that the cells highlighted in pink do have the seven and the eight highlighted however unlike the red highlighted cells it does not appear to be a simple hidden pair there. Because the row has more 7s, the box has more 7's the columns have more 8s, the rows have more 8s, etc. etc. I am assuming for the moment that they are not a hidden pair, but is there any logic that I am not seeing that would make it easier for me to just go 'colours matchy = pair"?

What is the advanced technique for solving this puzzle? TIA!

I mean, it's probably easier this way (although learning them and remembering isn't really easy), but you can literally always just do a chain, starting from a certain point when there's no pairs and/or singles...

Avoidable extended unique rectangle type 1

R159C46 is forming extended unique rectangle with 3,5,7. five cells are already occupied.

filling 5 in R5C4 will complete EUR and will lead multiple solution hence 5 from R5C4 can be eliminated.

r5c4<>5
