How to Play a 6x6 Sudoku Puzzle

A 6x6 sudoku puzzle has a grid of 36 cells, divided into six rows, six columns, and six boxes of 2×3. The aim is to place the numbers 1 through 6 so that no number repeats in any row, column, or box. Use logic to determine the missing numbers, based on the clues already provided in the grid.

Sudoku puzzles help you practice concentration, memory, and logical thinking. Solving a grid requires focus, attention to patterns, and decision-making. It's a great activity for keeping your mind sharp and relaxed at the same time.

How does difficulty vary in 6x6 sudoku?

The difficulty depends on how many digits are filled in at the start and how they are positioned. Easy puzzles have more clues and straightforward solutions. Harder puzzles require deeper logical steps. All follow the same base rules.

Tips for Solving a 6x6 Sudoku Puzzle

Look for rows, columns, or boxes with the most clues to get started. Use elimination and deduction to figure out where each number fits. Don't guess. Stay logical and revisit areas as needed. Patience is key.
