Sudoku of the Month

A particularly hard Sudoku. I found it quite testing anyway…

Sudoku 001

Nobody had a go…I told you it was hard…Tenner and a hug from the Fox for anyone who can complete it and figure out how to put it up on the forum…
:thinking:
:blush:

Gotta go out now Foxy, I’ll have a crack later.

Your right d00d, just stuck a grid round it, the race is back on, but not till laters

Must work out why it won’t bring the grid over?

Here it is with the grid

Great stuff Spitty, I must admit that having got to the stage where it was a toss up between the 7 or 3 in the top row, I tried to work it from there but in the end I guessed…I guessed right…
Did you manage to do it d00d?

I drew out a grid in excel and just print screen with new numbers in. I’d rather print off a copy though for working them out. I’ve got another one but I haven’t manage to crack it yet…

Yep Foxy, all good Sudokus start with a 50/50, It’s the permutations that get tricky/

On the hard ones that come to a dead end I usually fill in the empty squares in faint pencil with the only numbers that could possibly fit in that square. Most of the time there is one square that can only accept one number…But sometimes there isn’t. Out of all the sudoku’s I have done, there has only ever been one where I had to guess…And the one I posted was the one…
Well done to you and d00d… :+1:

It’s a bit like War Games, you have to dig in, and test all the possible combinations.
