I also do not understand how he placed that second 5. Possibly he had already seen the solution before he made this video.

doing it in your head is really only possible for the most simple puzzles. you get to a point in difficulty where there are 4 or 5 or 6 potentials in each box, and to be able to do things like spot hidden triples or (gasp) a hidden quad would be... i wanna say impossible for the human mind. if you can do an entire puzzle entirely in your head you either 1) need a more challenging puzzle, or 2) are Stephen hawking lol

I agree with 'Interdicted'. No way he can just put in the second 5. Plus NO EXPLANATION! I've looked at loads of these vids now and they offer no help.............or they are just too simple. PLUS. Anyone who does Sudoku's by writing 'possible' numbers in boxes b4 the actual number is in my opinion cheating! Do it in your head!!!!!!!!!!!!!!!!

This explanation video actually had about a minute of content "cut" before it was posted between the section on the "artistry" of the design and the first number being given. It was after a section where I went through identifying the other 5's that the 5 in r4c7 was found. You can't get this before other numbers.

theres no way he could figure the first 5, unless he has the ability of mapping the 9x9 in his brain with tons of posibilities.
