Masters Rules Of Sudoku Game
Here we are going to tell the masters rules of the sudoku game, you can also call them tips and tricks of the sudoku game because these sudoku tips and tricks will help you a lot in solving it.
Never Repeat A Number
As we have told above in the basic rules of the sudoku game that you shouldn’t repeat any number in any row, column, or in any grid box because if you repeat any number that means you are leaving any other number, and in this way, you won’t solve the sudoku puzzle.
Find The Reason & Apply The Logic
It’s a logic and reasoning based game, you have to always find the reason that why the number was filled on any particular cell of any row, column, or grid box, and then apply the logic for the rest numbers of the rows, columns, and grid boxes.

Never Try To Guess Numbers
It’s not a guessing game, never try to guess any number, because once if you filled one wrong number then it will become so much difficult to solve the sudoku because that wrong number will always direct you to another wrong number.
Always Start With Easy Puzzle
At the start don’t focus on the whole sudoku grid or all 81 cells and numbers, always start with the easy puzzle, as you will always get some already filled cells(squares), there will be at least 14 to 18 prefilled cells, focus on a single number, row, column or grid box which is mostly filled in the sudoku.
Use Elimination Method
There are some tactics to solve the sudoku, but the elimination method is so much helpful to solve the sudoku that’s why we are telling it in the master’s rules of the sudoku game.
In the elimination method, we can write numbers from 1 to 9 beside the sudoku and then target a row, column, or grid box, and then for the blank cells, we can logically eliminate the numbers and find the most appropriate number for a particular cell.
Use Cross-Hatching Techniques
The cross-hatching technique is a popular sudoku solving technique, and it is followed as a master’s rule to solve the sudoku puzzle.
In this technique, we focus on a single 3*3 row, column, or grid box and try to fill that by following the rules, and after filling it we keep it as a center point, and with the help of that filled row/column or grid, we try to find out the other rest numbers of the other row or columns.

How To Play Sudoku Game
Till now we have learned what is sudoku game and what are the rules of sudoku game, so now we will practice and learn how to play sudoku game =>
How To Play Sudoku Game – Set 1
We have told all the rules and tricks to solve the sudoku puzzles, so here we will start playing from an easy puzzle to a hard one, this is the first set, here only the first row is blank, and all other rows, columns, and grids are prefilled.
As per our rules first of all we have to find the easiest way to solve the puzzle.
As if we look column-wise, then you can see that only one number is missing in each column, and we can easily find that number by finding the missing number one by one in each column.
If you count the numbers of the first column like 1,2,3,4,5,6,7,8,9, then you will find that number 1 is missing in the first column, same in the second column, number 5 is missing.
Find the missing numbers of the rest columns and tell us in the comment section.

Here also, we will try to find the easiest way to solve it, if you see rows, then you will find that only one number is missing in each row, and we can easily count the numbers of rows and find out the missing number.
If you count the numbers of the first row like 1,2,3,4,5,6,7,8,9, then you will find that only number 8 is missing in the first row, similar in the second row, only number 5 is missing.
Find the rest missing numbers of the rest rows, and tell us in the comment section.

How To Play Sudoku Game – Set 3
We have solved two practice sets, Here we are moving to the next set(harder than those), here all other grid boxes are pre-filled, only the central grid box is blank.
And our rule is the same, and what it is, find out the easiest way to solve the sudoku, here we will target each number one by one, and with the help of the cross-hatching technique, we will solve this set.
Here we have to target each number one by one and find out the exact place of the particular number by cross-checking in other rows and columns.
Here we have targeted number 1, and as you can see in the image, we found number 1 in two rows and columns(those are connected with the grid box), and we can not repeat any number in any row or column, and after cross-hatching, we found only one sure place for number 1.
You can find out other numbers of the grid box, and tell us in the comment, which number will come after 1 in that grid (column-wise)

How To Play Sudoku Game – Set 4
We have learned enough about how to play sudoku game, so this is our last and little bit hard sudoku practice set, but the rules are the same, and what it is, find the easier way logically.
Here in each row, column, and grid box two numbers are missing, so are you going to tell me the easiest way to solve it in the comment section without reading further.
Here we can use both elimination and cross-hatching techniques, so as our rules, first of all, target one row/column or grid box, and then find the solution.
Here we are selecting the first column of the first grid box, if you count the numbers of the first column, then you will find that numbers 2 and 8 are missing.
If we try the elimination method, then you will find that number 8 is present in the 2nd grid box, so we can’t fill number 8 in its blank cell because we can not repeat any number in any row, column, or grid.
Similar second blank cell of first column is in 3rd grid box but it is having number 2 so we can not fill number 2 there.
But number 2 is missing in the second grid box and in the blank cell’s column and row, so logically we can fill number 2 in the first black cell of first column.
Similar to the second blank cell of the first column, only numbers 2 and 8 were missing in the first column, and we have filled number 2 in the first blank cell, so now we have only one blank cell in the first column, and the only number 8 is missing, so we can fill it there.
Now only one blank cell rest in the 2nd grid, and we can easily count that only number 6 is missing in the 2nd grid, so we can fill number 6 in that.
Similar to the 3rd grid. only one blank cell rest in that, and we can count that only number 1 is missing, so we can fill number 1 in that.
In a similar way, you can solve the whole sudoku, so now tell us in the comment, which number will be filled in the first grid’s first blank cell (between the number 1 and 2).
Here, we have solved the four practice sets, now we can assume that you have learned, how to play sudoku game, but, still, if you have any doubt, then you can ask in the comment section.
