Hi community
I have this sudoku and i'm tired of looking to him and can't find a place where i can put a number with 100% certain.

2..|4..|..7
.1.|..6|24.
..4|.2.|3..
.8.|3..|..5
..2|..8|.1.
9..|.4.|8..
..7|..3|..2
.2.|9..|.7.
8..|.7.|6..

if you guys just find a number with 100% sure, just tell me where to put that number and what technique you used.

Thanks for the help

Hi,

this Sudoku has 87 solutions, so there is no way you can be 100% sure about all numbers. :cheesey:

I determined that it has multiple solutions too using Sudokue.com

I selected the 9 rows from your post and Ctrl-C copied and Ctrl-V pasted them into the "Paste from Clipboard" option at:

http://www.sudokue.com

If you use Mode 4 you can try solutions and easily "UnDo" them and try another choice.

I regard puzzles with multiple solutions as bogus. They are just time wasters.

Hope this helps.
