How do you play sudoko?

Question

I know this sounds stupid but my dad got me this electonic sudoko game and I have no idea how to play, can anyone help me?
thanks in advance and sorry for bothering you about that.

Any solution methods for this game?

How do I know if I have put the right number?
is there a certain value that must be gotten from each straight line in the smaller (3*3) grids
example:straight line = 5,3,4will have a value of 12,must that vule be exactly the same in the lines?
example:blank square, 5,6, so the blank square must be 1 to add upt to 12??

Answer 1

sudoku is a number puzzle based o a 9*9 grid.The grid is also divided into nine 3*3 boxes.You are given a selection of values and, to complete the puzzle, you must fill the grid so that every column( boxes running down), every row( boxes running across) and every 3*3 box contains the digits 1 to 9 and none is repeated.
I hope that helps

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.

Advanced solvers look for "contingencies" while scanning, narrowing a numeral's location within a row, column, or region to two or three cells. When those cells lie within the same row and region, they can be used for elimination during cross-hatching and counting. Puzzles solved by scanning alone without requiring the detection of contingencies are classified as "easy"; more difficult puzzles cannot be solved by basic scanning alone.

Marking up

Scanning stops when no further numerals can be discovered, making it necessary to engage in logical analysis. One method to guide the analysis is to mark candidate numerals in the blank cells. There are two popular notations: subscripts and dots.

* In the subscript notation the candidate numerals are written in subscript in the cells. Because puzzles printed in a newspaper are too small to accommodate more than a few subscript digits of normal handwriting, solvers may create a larger copy of the puzzle.

* The second notation uses a pattern of dots in each square, where the dot position indicates a number from 1 to 9. The dot notation can be used on the original puzzle. Dexterity is required in placing the dots, since misplaced dots or inadvertent marks inevitably lead to confusion and may not be easily erased.

An alternative technique is to "mark up" the numerals that a cell cannot be. A cell will start empty and as more constraints become known, it will slowly fill until only one mark is missing. Assuming no mistakes are made and the marks can be overwritten with the value of a cell, there is no longer a need for any erasures.

Answer 3

Solving a sudoku puzzle can be rather tricky, but the rules of the game are quite simple.

A sudoku puzzle is a grid of nine by nine squares or cells, that has been subdivided into nine subgrids or "regions" of three by three cells.



The objective of sudoku is to enter a digit from 1 through 9 in each cell, in such a way that:


Each horizontal row contains each digit exactly once
Each vertical column contains each digit exactly once
Each subgrid or region contains each digit exactly once
This explains the name of the game; in Japanese, sudoku means something like "numbers singly".

Solving a sudoku puzzle does not require knowledge of mathematics; simple logic suffices. (Instead of digits, other symbols can be used, e.g. letters, as long as there are nine different symbols.)

In each sudoku puzzle, several digits have already been entered (the "givens"); these may not be changed.

The puzzler's job is to fill the remainder of the grid with digits –respecting, of course, the three constraints mentioned earlier.

Answer 4

you have to fill in the grid so that the numbers 1-9 appear with no repeats on each row, column and within each 3x3 square (there are usually 9 3x3 squares (or 89 squares in total)

Answer 5

Fill in the empty squares so as that the numbers a million by using to 9 extra healthful into each and every 3x3 block of squares, each and every row and each column. to artwork out a huge type, you will would desire to do away with the numbers already in the sq.'s row, column and 3x3 block..... you get extra constructive with prepare, reliable success!

Answer 6

Its very easy you have 9 rows and 9 coloums and they are devided in 9 bloks with 9 smaller blocks inside. Now you have to put the nummbers 1-9 in the rows, coloums and blocks with out repeating a number in a the same row, coloum or block. hope it helps enjoy your game.

Answer 7

each 3X3 grid has numbers 1-9 without repeats

each horizontal line has numbers 1-9 without repeats

each vertical line has numbers 1-9 without repeats

a sudoku grid usually has 81 spots (9X9) to place numbers, and usually about 5-12 numbers are filled in for you

Answer 9

you just look through the vertical columns and then horizontal rows and which number is the most in the given sudoko.then starts with the most nos. one.

Answer 10

you must fill every row,box,column with numbers 1-9
