The New Sudoku Players' Forum

[Diana Moon]

OK, I admit it, I'm not brilliant, but I did reasonably well at the logic part of the GMATs...however, I am completely stuck on something very basic.

I grasp the essentials of Sudoku.

I could describe it, but I think it's easier to look at it here:

Why is the ONLY solution Column 6, Row 3? Why could the one not go into Column 7 or Column 8?

I do not understand how they have narrowed down ! to C6, R3.

Thank you!

OH NOW I SEE IT. OH JOY. I'M LEAVING THIS POST UP ANYWAY. THANK YOU GOD I FIGURED IT OUT.

I forgot that Block 3 already had a one, so it eliminates the columns in that block.

Wow.

I've been thinking of this since yesterday.
