slow starter, but no greens

I really wonder how these can be done with no greens.... any hints?

I can't really concieve of how to do any but the most elemental Sudoku without notes/greens.

When I first learned on paper, we used a dot code.

mamabear - cross-hatching got some filled in today, then mixing in some row/col/3x3 completion scans was all that was needed

What is "cross-hatching"?

okay, i start in upper left 3x3 looking for places for 1s, then to the center top 3x3 looking for 1s then upper right, then center left 3x3 etc.

then i repeat the process looking for 2s

and so on

Ah, I see. I "know" how I solve Sudoku, but don't know any terminology to describe it to anyone else.

there ya go

i do cross-hatching as i scan until nothing looks obvious. then i move on to row/col/3x3 completion and then move back to cross-hatching until it's done. or until something more involved is needed.

this one definitely required only Easy skills, but was pretty slow. well, there were one or two spots where i had to think something through.

To solve without greens I use crosshatching like britlefish. I check all 9 blocks for 1's, then 2's, and so on. I also look at empty cells to see if it possible to figure out what belongs there by seeing what number is missing from the corresponding row, column, and block. Then I repeat crosshatcing. It sometimes helps to look at an individual row, column or block and see if I can figure out what numbers are possible, or not, in the cells.

So, basically the same thing as filling in the greens, just not writing it down.

I'm assuming I know what y'all mean when you say "greens"... you do mean using the shift-key to allow multiple possibities to be noted on the puzzle squares, right?

Yes

I use this technique on all puzzles, even the "hard' and "expert", to solve as many cells as possible so that I can minimize the greens I have to enter.

Another thing to look for is blocks with all three cells in a row or column filled in. This often helps to determine what numbers can not go in cells in an adjacent block.

If you want more tips go to scanraid.com. There are tips from basic to advanced.

I wonder if Sudoku is being used to teach logic to students.

I bet it is in japan where it originated. It should be here. My 6th grade teacher started me on crosswords to help learn vocabulary words. I still do crosswords every day.

We've got a tablet of Kid's Sudoku, and I keep trying to get my just-turned-five-year-old interested, but they're just a leetle bit beyond her right now.

this one is so easy you can even dispense with hurshy's #1 rule of sudoku

Easy my sphincter

What is Hurshy's #1 rule of Sudoku?

The World may never know.

"Mister Owl, how many licks does it take to get to the Tootsie-Roll center of a Tootsie Pop?"

One... two... three... CRUNCH! Three.

How many licks DOES it take? The world may never know.

:)

hey saucygirl :)

this is my favoritest sudoku site ever. i know you will like it too. :D

HEY girl!!!

yay! there you are!

wolfrick. precisely 4309 licks. I did it when I was in the 4th grade. Only a 4th grader could have the combination of detrmination of will and yet not be bored to death by the task.

Go.

Hah! That's hilarious, Dave.

mamabear?

Wolfrick, try http://www.dailysudoku.co.uk/sudoku/index.sht
ml if you're still here. They have a kids' sudoku puzzle each day, plus free archives. My favourite puzzle there is their squiggly sudoku. :D

I just did today's 4x4 with my 5-year-old, and she totally got it!!! Yay!

Oh, wait... I was on dailysudoku.com, not *.co.uk

I had to whip up a table in Word to work it with her, though.

Thre's a dailysudoku.com as well?

Apparently :)

Different top-level domain, different site, most likely.

Ah, fair enough. I found daily sudoku UK before finding iron sudoku. Haven't been back to the UK site in ages though, haven't had time. ^^;
