How to Play Sudoku

Sudoku is a fun logic puzzle played on a 9×9 grid divided into nine 3×3 subgrids. The goal is to fill the grid so that each row, each column, and each 3×3 subgrid contains the numbers 1 through 9, without repeating any number within the same row, column, or subgrid.

Here are the steps to play Sudoku:

Start with an empty grid or a partially completed Sudoku puzzle. Look at the partially completed puzzle and identify the given numbers (usually shown in bold or larger digits) that are already placed on the board. Analyze the puzzle and use logic to fill in the empty cells. The rule is that each row, column, and 3×3 subgrid must contain each of the numbers 1 through 9 exactly once. Choose a number and look for places where it can be placed according to the rules. Consider which numbers are already present in the row, column, and subgrid. If there is only one possible location for the number, fill it in. If there are multiple possible locations, move on to the next number and repeat the process. Continue applying logical reasoning and fill in as many numbers as possible. If you get stuck and cannot continue, you can use techniques such as “pencil marks” or “candidate elimination” to narrow down the possibilities and find the next number. Keep filling in numbers and applying logical reasoning until the entire puzzle is completed correctly. There are also different difficulty levels for Sudoku puzzles, which affect both the complexity of the puzzle and the number of given clues at the start. The fewer given numbers there are, the more challenging the puzzle becomes, and it may be necessary to use more advanced solving strategies.

Good luck and enjoy playing Sudoku!
