SuDoKu? (1 Viewer)

[fatmuscle]

Anyone do these sudoku puzzles found in the Daily Telegraph?

I'm obsessed with them.

I have to do it everyday (unless i'm way too busy).



If you do these puzzles,
what are some of the methods you use to solve them?



Also, if you download that sudoku program, there's variations on the puzzles. Like a 9x15 sized puzzle.
I shall do it after my exams.

My modern teacher is also infatuated with them. Her infatuation distracts her from, err, teaching.

She always tells us about them and psychs up about them. Yep, we are kinda doin our HSC here, luv.

They better be as good as what people make them out to be. I don't want to be wasting, what, a buck twenty five on a newspaper when I can buy three - THREE - Chuppa chups for the same price.

 

[fatmuscle]

well, we get home deliver, so it's a bit cheaper.

My mum, dad, sister and myself read the paper.

we use the paper for lining my dog's shit section.
and we often use scraps of paper for other stuff.
so that $1.25 can go a long way. Not just for SuDoKu

 

[jumb]

scan one up so we can see it

Try the Dion Cube for a bit of an extra challenge. (Sudoku in 3 dimensions)

 

[fatmuscle]

you've just given me a challenge.
I will do that example.

 

[mr EaZy]

whats up with soduku?

just write the missing numbers outside each column and each row and cross them off as you get them one by one. whats so hard about that.

i did it and thought- is that it??

doesn't UTS give free daily telegraph papers?
and isnt it $1?

which paper are u talking about?

 

[fatmuscle]

i dunno how much a paper is

the dion ended up being pretty easy.
you have to do like 2 levels, then there's a pattern, and u just follow the pattern, fill in the numbers blind folded.

The aim of the puzzle is to enter a number from 1 through 9 in each cell of a grid, most frequently a 9×9 grid made up of 3×3 subgrids (called ‘regions’ ), starting with various numbers given in some cells (the ‘givens’ ). Each row, column and region must contain only one instance of each number.

An example. I’m a big fan, despite my lack of success at any other level above easy.

This beginners guide is also interesting.

Ah yes Sudoku.. mmm.. They appear in all the major newspapers, well at least the SMH, Daily Telegraph and the Australian.

I love to solve them except at some point in the 'tough' and above rated (by SMH) ones, I don't know any techniques besides guessing, even if it is reasonable guessing by trying to predict the outcomes.. anyone have any hints?

There is also an apparent pattern formed by the initially given numbers and their places on the grid. Does this help in solving, or anything, or does it just look nice?

 

[RingerINC]

my bro is mad at them, he does the massive 16x16 ones.

its not too hard, just takes a bit of time and concentration. first u start with column or row with most number given already. then work on that one. then go to the next one and use elimination as the primary method of 'guessing'. keep going problem is u fock up one and probably focked the whole thing.

I love SuDoKu. I do them in my study periods at school

i dont look at the columns, i look for the number with the most already given then work from there.

I am very, very obsessed with them. My greek lecturer once saw me doing one in the lecture, and waited till I noticed. The only problem was that I noticed him waiting because someone nudged me after a minute of silence.

I've been trying to refine my method, but I find the best way to start is the "red bars"- ie you imagine red bars coming out from numbers, thus excluding positions.

Then when you're out of that, you move onto the "counting from one to ten" for 3x3 boxes, the rows, and the columns.

Then, I move to the "plan ahead"- if this goes here, that goes there, etc.

Generally I go in that order, unless the first methods are working.

I do the sudoku in the SMH every day. It's kinda hard to explain the tactics, but I can get the tough ones done in 15 min. so I must be doing something right.

 

[fatmuscle]

so SuDoKu is in SMH now?

There's a few cool puzzles.

DT has SuDoKu and the jumble!
SMH has 'Target'


btw, does anyone know if SuDoKu's are all symmetrical?
like when u get one to do, the boxes filled are in a 180 deg symmetry

 

[iamsickofyear12]

I use a combination of multiple strategies. I don't do them much though.
