The goal of Sudoku is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 section contains all the numbers 1 to 9 without repeat.
The initial numbers in the cells are given as clues to help you solve the puzzle.
Rules
Each row must contain all the digits from 1 to 9 without repetition.
Each column must contain all the digits from 1 to 9 without repetition.
Each of the nine 3×3 section must contain all the digits from 1 to 9 without repetition.
Gameplay
Start by examining the given clues (numbers) in the grid.
Identify empty cells where you can logically deduce the correct number to place.
Begin by selecting any empty cell.
Determine which numbers are possible candidates for that cell based on the numbers already present in the same row, column, and 3×3 section.
Choose one of the possible numbers that does not conflict with the rules mentioned above, and fill it into the cell.
Repeat this process for each empty cell, focusing on one at a time and using logic to deduce the correct number.
As you fill in more numbers, new chances for deduction may arise, allowing you to fill in additional cells.
Be careful to avoid conflicts, such as placing a number that violates the rules of Sudoku.
Continue this process until all cells are filled and the puzzle is solved
Tips
Start with easier puzzles if you’re new to Sudoku to familiarize yourself with the rules and strategies.
Use the process of elimination to narrow down the possibilities for each cell.
Look for patterns in rows, columns, and sections that can help you discover missing numbers.
Don’t be afraid to erase and try again if you make a mistake.
Practice regularly to improve your skills and speed.
