Sudoku Help?

Question

We were given a Sudoku for extra credit. I am so confused. Any tips for getting it done?

I know the rules, but its hard.

Answer 1

Does anybody seriously hand out Sudoku for homework? In class maybe, but take home, seriously?

You really should learn to solve them for your own enjoyment and self improvement, but just finding a solution is too easy.

There are too, too many places to get solutions. The link is for one place.

Answer 2

basically what you're supposed to do is not repeat a number between 1 - 9 in any of the 9 boxes or in horizontal rows or vertical ones.

if you post the actual sudoku box, i can just answer it for you.

Answer 3

Scanning

Scanning is performed at the outset and throughout the solution. Scans need to be performed only once in between analyses. Scanning consists of two techniques:

* Cross-hatching: the scanning of rows to identify which line in a region may contain a certain numeral by a process of elimination. The process is repeated with the columns. For fastest results, the numerals are scanned in order of their frequency, from high to low. It is important to perform this process systematically, checking all of the digits 1–9.
* Counting 1–9 in regions, rows, and columns to identify missing numerals. Counting based upon the last numeral discovered may speed up the search. It also can be the case, particularly in tougher puzzles, that the best way to ascertain the value of a cell is to count in reverse—that is, by scanning the cell's region, row, and column for values it cannot be, in order to see what remains.

Answer 4

its all about logic
1-9 going up and down
1-9 going across
1-9 in each square
