1 LOOK BEFORE YOU LEAP. check to see if there is any other number that can fit in a box before you write one in.
2 PENCIL IN POSSIBILITIES. write very faintly what numbers can fit in a box. (eg if there is 3 possible numbers then write them in the real small, and then when you put one of those numbers in that row/column/large box, simply cross it out) eventually you'll have 1 nubemr penciled in, and that MUST be the number that goes there.
3 DOUBLE CHECK, DOUBLE CHECK, DOUBLE CHECK. need I say more?
Hope that helps. (step 2 seems to be the most affective)

I'm a fresh newbie so maybe I don't get it, but in the "last number in a row" example, why could not a 4 be placed in B1? The 4 in Box B should only remove Row C and Column 5, shouldn't it?
Andrew Stuart writes:
Looking at 4s from the point of view of the box gives us three places 4 could be, including B1 - none contradicts the rules. A1 or B2 will also do. So we can't decide based on the box. The way to choose which is right - in this case - is determined by the fact that in the row there is only once place for a 4. There will be *some* easy puzzles that be solved only by looking at how to fill boxes but its easy to check rows and columns as well for a faster completion.

I enjoy doing the puzzles in the newspaper
I got bord with the Jumble so I moved on to the
celebrity cipher and mastered that one .My brother got me started with Sudoku and its really a
challenge .Just started it last week. I think the eyeballing is a good way to start. great web
site, keep up the good work.

After years of struggle, I decided to go to basics - and used my "eyeball". Thank you for this piece.

I developed something I call an "Index." You make a list of all the numbers NOT appearing in a column, or row, or even a square. Test the index against each blank position in the column. If you get a match in the neighbourhood for each number in the index but one, that number goes in the blank cell. The "neighbourhood" includes the contents of the row, column and square that that blank cell is in,
It may not always work, and often you may have to do some manual testing.
Please tell me that other people are using this device which came to me.
