How to play a Sudoku Game:
In Sudoku, a player has to fill 9×9 numbers from 1 to 9 in every row, column and 3×3 grid, without repeating any number.

- First you have to understand the grid. The game contains 81 cells, which are arranged in the 9 boxes of nine cells each containing a number.
- You have to find a cell that contains 1 number.
- You have to Start with the Easy Numbers. Look for each row, columns or subgrids that are already filled with numbers. This makes it easy to figure out the missing numbers.
- Check which numbers are missing in the row, column, and subgrid, and eliminate those numbers that are already used elsewhere in the same row, column, or subgrid. This will help you narrow down where each missing number should go.
- Sudoku uses logical deduction. It’s all about logic.
Look for naked singles: If a number can only go in one place in a row, column, or subgrid, then you can place that number in the empty cell. This is called a “naked single”.
Look for hidden singles: If a number can only appear in one position within a row, column, or subgrid, even if other numbers are in that area, it must go in that position.
Pencil in possibilities: In more difficult puzzles, it might help to pencil in possible numbers for empty cells. This can help you visualize potential moves before committing to a number.
- In sudoku you have to work systematically. Start with those rows and columns which are mostly filled with numbers. Work through each grid to spot the numbers that can fit in the certain spaces.
- While it can be tempting to guess, Sudoku is based on logic and should be solvable without making random choices. Guessing can lead to mistakes, which could make it harder to solve the puzzle.
- You have to go step-by-step, filling in numbers in each grid. The player has to apply logic at this place. Each correct placement of numbers will bring you closer to the completion of the sudoku game. You will have to fill each column and rows without repetition.
- Once you’ve completed the puzzle, double-check each row, column, and subgrid to make sure all the numbers 1-9 appear exactly once. If there’s an error, retrace your steps and see where you might have gone wrong.
