# How to solve this Sudoku?

Here is the sudoku - I could think the following only.

The top number box 3 coloumn wise should have some number - 6,7,3 (in some order). The box 3 column 2 -- 2,5,8 ( in some order), and box 3 column 3 - 1,4,9 in some order. Rest, I am really not able to identify what is wrong.

I am really clueless here, I am not able to think further. What logic am I missing here?

Hints (that should be sufficient to allow simple reduction of possibilities):

In the second row, first box, you have a cell with possible numbers (4,6), and one with (1,6). In the second row, last column, you have a cell with (1,4) as possible numbers.

Thus, no other cells in this row can be (1,4,6), which nets you a 7 somewhere in the upper right 3x3 box.

After that, check around for other 7s - you should be able to find two immediately. Then check twos - you should find one. Carry through to completion.

• But 7 can come even on the second box, 2 nd row 3rd column. Also, 7 can come on third box - 2 nd row 1st column and 2nd column. So, in the second row - series - 2,7,8 can go anywhere. Sorry, I haven't understood about 7 yet. Please elaborate a bit. Commented Jan 2, 2016 at 22:37
• @dexterous_stranger I think emrakul messed up, because 146 is taken, the only number left for the first number second row third box is 7. From there it works Commented Jan 3, 2016 at 9:56
• @DrunkWolf By "upper right box," I meant to refer to the upper-right set of nine squares; I've edited to clarify.

• @Emrakul ah that makes sense then :) I do the occasional sudoku but am fairly unfamiliar with how people describe them :) Commented Jan 3, 2016 at 10:20
• @DrunkWolf no worries! :] There are formal names that nobody uses, and I don't even think I'm using them here... but oh well, it needed to be clearer, so thanks!
