SuDuKu

A Sudoku game is a simple way to practise logic and concentration, whether you are new to number puzzles or already enjoy solving them. This game offers five difficulty levels, a Daily Challenge, and a hint button for moments when you need help. You can select a number by clicking or tapping, and you are allowed up to three mistakes, so take a moment to check each move.

How to play the Sudoku game

In classic Sudoku, the goal is to complete a 9-by-9 grid so that every row, every column, and each 3-by-3 box contains the numbers 1 through 9 without repetition. The starting numbers are clues; use them to work out which values can go in the empty squares. Sudoku is a logic puzzle, so you do not need to perform calculations.

Before placing a number, check its row, column, and box. If the same number already appears in any of those three areas, it cannot go in that square. This quick check can help prevent errors and is especially useful when you are close to the three-mistake limit.

Choose from five difficulty levels

The five difficulty options let you choose a puzzle that suits your current skill and preferred pace. If you are just starting, try an easier level and focus on learning how the rows, columns, and boxes work together. More experienced players can select a tougher level for a greater challenge.

Work through the grid steadily rather than guessing. Look for rows, columns, or boxes that already contain many numbers, since these areas may make possible placements easier to narrow down. If you feel stuck, use the hint button as a prompt to keep progressing.

Try the Daily Challenge

The Daily Challenge provides another puzzle to take on alongside the difficulty-level options. It can be a useful way to build a regular solving habit and practise applying the same logic to a new grid. Take your time and review each move before selecting a number.

Quick gameplay tips

• Scan a row, column, and 3-by-3 box before placing a number.
• Use the hint button when you cannot identify a sensible next move.
• Keep the three-mistake limit in mind and avoid random guesses.
• Click or tap a number to select it while playing.

Enjoy a focused puzzle session

With five difficulty levels, a Daily Challenge, and hints available when needed, this Sudoku game gives players several ways to approach a puzzle. Start at a comfortable level, use the grid’s clues to guide your choices, and check each placement carefully. A patient, methodical approach is often more useful than trying to fill the board as quickly as possible.
