The 1258 there places those digits in row 7 in the other two boxes. As such, the only digits that can go in box 9 on row 7 are 479. The seven is placeable right away and then you get a 49 pair which resolves right away as well. Basically, New York Times is a one trick pony...

@midehv4 жыл бұрын
I'll try to explain and probably do a terrible job. A triple doesn't mean you have 3 cells that have all been constrained to the exact same three numbers (though that is possible). It means that across 3 cells you have determined that 3 different numbers need to appear there, in some order, to satisfy (in this case) the column. So a 7 being restricted from the middle cell limits the possible combinations of the triple, but doesn't change the fact that those three digits need to be in those three cells. As a check, try to place one of the digits outside the triple, perhaps a 7 in this case since it's the one not showing three times in the triple, and see if you can still satisfy the column. If you placed a 7 in the top left corner of the grid, you would reduce all 3 cells in the triple to 2 and 5. You can't possibly fill three cells with only 2 and 5. Hope this helps.

@@odesseydekimola I think your question is in reference to the pencil marks. Remember that corner pencil marks suggest that those cells are possible locations for a number in a box, but center pencil marks are spots that HAVE to be one of the numbers marked. Note that by the end of the video the 5 ends up where you suggest that it can in box 7, but that't not the point of discovering the triple. In fact upon discovering the triple, he doesn't disambiguate the triple immediately or even after a while. He's just using that information to eliminate candidates in column 1. I suppose to answer your question, by finding a triple, all in column 1 in this case, he's not trying to find more information about box 7, he's noting that 2 5 and 7 can't appear elsewhere in column 1, notably a 7 in the top cell. At the 5:51 mark, take a look at what affects column 1 with the notations and not box 7. Edit: After reading your question again, I realize my answer was slightly off from what you were asking. You were asking how his constraints had any affect on where digits go in box 7. The answer is they don't. If you find a triple all in one row or one column, as in this case, those constraints are applied to the column.

We cannot also predict that 7 will be in column 1 row 6 as it can also be in column 2 or 3 row 5 and 6... Moreover 2 cannot be placed in Column 1 Row 6 because it has to be placed in Column 8 Row 6 (from further solving, I went a little different way) How on the earth am I supposed to find that sort of hidden triple in sudoku?

We do not predict anything, we are just saying that in those 3 cells the ONLY possible candidates are 2,5 or 7... their exact position in the column, at this point isn't important, but we are sure that in those 3 cells there is a 2, a 5 and a 7 in any order.

This took me an embarassingly long time (more than 1h oops) but I managed to do it without bifurcating at the very least!

It took me 8 hours, but I fell asleep half way through and finished the next morning. More than an hour of actual time if I'm honest though.

HELP, PLEASE! I can't do triples to save my life. How do I look at something like this: i.postimg.cc/brDqysmN/Sudoku.png and know for a fact that I have a 238 triple on my hands? Since none of the numbers are restricted to those cells, I can't just kick out any of the other numbers.

How do you know it's a triple? I don't think it is. Because, as you say, you can't rule out the 1 or 5. You could rule out the 5, if you get the first triple in this video, but you would still have an unknown 1.

Six months later, I'm able to solve the puzzle in 1:14:26. The triple in Row Five was a complete pain to find. I don't like puzzles like this.

Missed the obvious... 3/6 pair in box 6. That's embarassing 🙄

400th, p.s. I think you got lucky, it usually spots double uploads and doesn't give an id to the 2nd one. But I'll go out on a limb and say y preferred the first one.
