Master Sudoku

Master Sudoku is a logic-based number puzzle where you fill in a 9×9 grid using the following rules:

Rules of Master Sudoku Each row must contain the numbers 1-9, without repetition. Each column must also contain the numbers 1-9, without repetition. Each 3×3 box (also called a "region" or "block") must contain the numbers 1-9, without repetition.

Solving a Sudoku Puzzle

Start by identifying given numbers (the clues). These are fixed and cannot be changed.

Use logic to deduce missing numbers. Look for rows, columns, or boxes where only one number can fit.

Scan and cross-check: If a number is already in a row, column, or box, it cannot be placed again in that section.

Pencil in possibilities: Write small numbers in empty squares to keep track of options.

Use elimination techniques: If a number can only go in one possible place within a row, column, or box, place it there.

Hints System Some Sudoku games allow up to five hints to assist you.

A hint typically reveals the correct number for one square.

Use hints strategically when stuck, especially if you are unsure of your logic.
