OK - Ask me a Sudoku Question!

Submitted By: Gath from Sudoku.com.au

To kick things off - ask me a sudoku question that has been bugging you.

Anything! A puzzle that you haven't been able to solve, or an explanation of a technique, and I'll do my best to answer it :)

(Of course, I might get Steve to help with the really tough stuff :) ).



Indicate which comments you would like to be able to see

Hi! It's not a ? on the puzzle, but on my grid positioning. Today it overlaps the sentence 'choose a # & put it in the grid' that's above the numbers. Yesterday it was fine. Can I fix it? Love all the improvements & extras!!!
31/Jul/07 6:26 AM
Me again, I know why it happens now, but I still would like to know if I can fix it. When I add the 'Possibilities', the grid grows downward over the sentence and into the numbers. I don't recall that ever happening before. Any suggestions would be appreciated. Thanks for all you do (even if you can't fix the prob.).

Ok Gath an easy question with a hard/long answer.
How do you make a Sudoku? Given the rules, not forgetting the one most forget; 'Each Sudoku puzzle has a unique solution'

Hi vdV,

Now that is a tough one to explain, but here goes:

Note - there are *many* ways to generate sudokus, this is just one.

1. Start with a completely blank grid.
2. Solve the sudoku. By this I mean fill in all the squares keeping to the 3 rules of sudoku.
3. Make 2 More...

maybe it wasn't so tough
03/Aug/07 11:25 AM
Gath is this a trick answer, where is step 5
03/Aug/07 5:04 PM
Hi Everyone,

Sorry vdV, step 4 should read:

4. Try all combinations of numbers to solve the sudoku. If there is 1 solution, then go to step 3. If there is more than 1 solution, go to step 6.

The tough puzzle for May 28, 2007 appears to be one of those that require advance techniques. Anyone have a solution or stratagem to post?

Hi Dave,

Now *your* question is going to take a little while to get back to. Solving a tough puzzle takes me ages!

I'll check it out & get back to you.

How does someone who is a math ignoramus attack this problem?
Was first time lucky (months ago!) - not a good thing. Okay, where to start?

CINDY, I am not Gath and I hope he does not mind me 'helping" with this question. I would put my thoughts on your page, but you are not a member with a page available.

Suduko is not about math, it is about logic! You do not add, subtract, multiply or divide anything. You do count to More...

NOW Gath, I have a question. On a suduko game on my puter that hubby bought for me, I find on their easy, they play nothing like your puzzzles. I repeatedly get a set of possibilities I cannot find a way to work with. It is so often present, I wonder should there be some way to work with it to More...
24/Aug/07 2:21 AM
Would you know where I can find mega sudoku puzzles and if so, maybe in a large size(poor vision). Thanks!

27/Aug/07 2:42 AM
Hi MizTrica1,

When you have possibilities like 25, 27, and 257, then you usually must rely on what is happening in the other squares to solve these three. Just looking at these 3 squares in isolation will not solve them.

rtshores, try googling 'large print sudoku'.

30/Aug/07 2:02 PM
THANKS GATH, that is what I have been doing, but I kept finding it so many times, wanted to be sure I was not missing some secret.

Are there formal criteria for classifying a 3x3 sudoku puzzle (i.e. easy, medium, hard)?
16/Sep/07 12:18 AM
Hi A student gave me a rubik cube sudoku puzzle with the numbers 1 - 9 on each side. Have you seen these? I can solve a normal 3X3 cube so I didn't think this would be a problem but I do not know the orientation of the way the numbers point on each side. The solved cube is 1 through 9 starting More...
20/Sep/07 9:32 AM
Hi Everyone,

Richard - 3x3 puzzle? Do you mean there are only the numbers 1-3 used?

Kim - I've never seen a Rubik's cube like this, but I would guess that the manufacturer would arbitarily decide which way was 'up' for the cube, and align the numbers 1-9 with that in mind. (and hopefully provide a picture!)

17/Oct/07 6:56 AM
why do I only get the current jigsaw puzzles when I attempt to work those that have previously been done. It doesn't matter which date I use...its always the same as the current puzzle. Help!!!!
19/Oct/07 8:34 AM
Hey there, new to this whole sudoku thing (and am admitting im addicted to it), but I just wanted to get a feel of the average time it takes to complete a sudoku...

On easy, I see people posting 2/3/4 mins, (I am getting 10 mins avg)
On medium, I see people posting 4/5/6 mins (I am More...

PETER, I have been doing these sudoku puzzles since May and I am not fast! I do not even turn on the timer, I just enjoy doing them no matter how long it takes me. I do know I am enjoying it more as I get accustomed to the computer clicks and to some of the ways to look at the puzzles. Just keep on More...

hey, can i eat a pancake
30/Oct/07 10:46 AM
Hello all. I am a newbie and am having great fun solving the Easy and Medium puzzles. BUT, for the life of me I cannot solve a Hard one. I understand , I think, the technique of "pairs' but I need some helpful hints, please, folks.
02/Nov/07 5:36 PM

Gath, this was in today's thread on the tough page. Didn't notice you were still inviting queries to this page, and hope this isn't too late an entry:

"PJH From NP. Hi all! Why do some cells flash red when I fill in a different one? Sometimes only one will flash and other times More...

Hi Garth, mines not a question but a request. PLEASE remove Britney Spears,from the adds. Many Thanks.
09/Nov/07 11:54 AM
Hi Garth,

I always get a problem. In a sudoku if the configuration is
... ab abc ... pqab .. ... ... ...

Some times, only c is taken in place of abc and sometimes it is taken as a pair.. ab ab .. (i,e, c is removed. Any criteria for this? if so kindly explain.

11/Nov/07 11:04 PM
How can I get a Sudoku instruction manual ?
12/Nov/07 9:47 AM
Hi Garth,
I'm a newbie and get confused over two possibiilties a square. But I have never seen anywhere that instead of clicking the possibilities check box that you can just right click on the square after the number you have selected and it will show this as a possibility. PS luv the site, will become a Supporting Member as soon as I can.
Take Care,

Wagdy, if you are using a recent version (7) of Windows Internet Explorer you can zoom the screen in and out with "Ctrl"+ and "Ctrl"- (ie the control key and the + key [or - key]). You can also use the zoom button at the bottom right of the window.

UNDO is not functioning when Possibility in Grid Format is checked, the possibilities are hidden when UNDO is pressed.
