What is Sudoku?
Sudoku is a Japanese puzzle game based on the logical placement of numbers. A game of logic, doesn?t require any calculation nor special math skills; all that is needed are brains and concentration. The goal of Sudoku is to fill a 99 grid with numbers so that each row, column and 33 section contain all of the digits between 1 and 9.
Learn to play Sudoku with some tricks:-
Now comes the main part where I will tell you all how to easily learn and play sudoku whether you are beginners or not. I don?t go too deep into technical terms( that?s my habit) and try to answer each blog article in as easy way as I can.
As I mentioned above you have to fill the 9X9 grid with numbers from 1 to 9 so that no numbers repeat themselves in any row or column. For example-
As you see above is a Sudoku puzzle of 9X9 grid that contains 9 sections of 3X3. In this some number are already filled and we have to fill the other numbers so as to complete the puzzle.
The rules are that no same number can repeat it self in row and column( I know I told you all same thing above but??. now I am going to explain). This ?no repeat? statement means that if you see number 7 in top row and second column ( in the above figure) and by the rules now 7 can?t be repeated in the top row and second column and the 3X3 section (in which it is already present).
You all have to think really hard so as to solve this puzzle because this only tests your sharpness of mind and concentration power. You have to keep patience also because sometimes you may struck and don?t get the solution for some time. ( No, don?t struck your head on wall. No never).
How to think to solve the Sudoku?
You have to first look at the puzzle closely and look for any numbers which you can fill as according to rules in first go. If you see above you can fill 7 in fifth row and third column. See below
In the same way look for other boxes also which can be filled very quickly. After that first look at the row and then the column and then the section 3X3 and see which number satisfy the puzzle. ** TIP: Always look for the column that has a number missing which it?s adjacent columns have. You will have one advantage of this is that you would be easily able to eliminate some boxes where the number can?t be filled. For example: In the above 7 was present in both column 1,2 and was missing in column 3. So because of that we easily eliminated the column boxes of Section 1 and section 3. So, because of that we were left with an empty box in section 2 column 3 which finally we filled with 7. See the diagram below:
I know the image editing is not good. Well I laughed too at my editing skills. But okay I am comfortable in writing blog and rest work is only for your better understanding of concept. I?ll work on my editing as well. I hope all you will solve each and every Sudoku puzzle that comes in front of you very easily after reading my tips for the game.
