How to Play Sudoku: The Basic Rules and Tips for Beginners
Sudoku is a game that consists of a 9x9 grid divided into nine 3x3 boxes. Some of the cells in the grid are already filled with numbers from 1 to 9, while others are empty. Your goal is to fill in the empty cells with numbers from 1 to 9, following these rules:
Each row must contain all the numbers from 1 to 9, without repeating any.
Each column must contain all the numbers from 1 to 9, without repeating any.
Each box must contain all the numbers from 1 to 9, without repeating any.
That's it! There is no math involved, only logic and deduction. To solve a sudoku puzzle, you need to use the clues given by the numbers already in the grid, and eliminate the impossible options. Here are some tips for beginners:
Start with the easy puzzles, which have more numbers given and fewer empty cells.
Look for rows, columns, or boxes that have only a few empty cells left. Try to fill in those cells by checking what numbers are missing and what numbers are already used in the same row, column, or box.
Use pencil marks or notes to keep track of the possible candidates for each cell. For example, if a cell can only be either 2 or 5, write those numbers in the corner of the cell. This will help you narrow down your choices later.
If you get stuck, don't guess. Instead, look for another clue or use a hint if available. Guessing can lead to mistakes and frustration.
