What is Sudoku Game?
Sudoku game is a very popular Japanese puzzle and brain game that purely based on logical placement of numbers. You don’t need a calculator or any special maths skill to play the game. All you need is concentration and reasoning.
How to Play Sudoku Game
The main aim of the game is for you to fill the 9×9 grid with numbers, such that each rows, columns and 3×3 sections contains all the digits between 1 and 9.
You will notice at the start of the game that some of the squares have already been filled with digits. Now you need to apply logic and fill the missing digits, so that the grid becomes completely filled with digits 1 to 9.
A move is incorrect in the game if:
- Any column contains more than one of the same digits from 1 to 9.
- Any row contains more than one of the same digits from 1 to 9.
- Any 3×3 grid contains more than one of the same digits from 1 to 9.
Helpful Tips for Playing Sudoku Game
- First tip is to check for rows and columns of 3×3 sections that contain not less than 5 numbers. Now in the remaining empty cells, try to fix the other numbers that have not been used there. This will help you discover the numbers that should be placed in these empty cells, considering the numbers that have already been fixed in its row, column and its 3×3 grid/section.
- Second tips is to visually break up the grid into 3 columns and 3 rows. There will be three 3×3 grids in each large row and three 3×3 grids in each large column. Now, check out for columns or grids that have two of the same number. By logic, you should see a 3rd copy of the same number in the remaining 9-cell section. For the remaining 9 positions, try and see if you can find the location of the missing digit. You can check Sudoku Official site to learn more about Sudoku game.
