How to play Classic Sudoku
Take a moment with Classic Sudoku before moving to another game. Fill all cells with 1–9; do not repeat a symbol in any row, column or region. Keep the game area visible while you use its controls. Choose a comfortable screen position before beginning. Check the relevant rule before repeating a move.
Build a steady rhythm
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Refer to the controls when needed.
Your goal
Fill all cells with 1–9; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
Step by step
- Select an empty cell. The original clues cannot be edited.
- Choose a symbol from the number pad, or type it on a keyboard.
- Turn Notes on to record candidate symbols without committing an answer.
- Use Check entries to check your filled values. Hint reveals one value from the verified solution.
- Complete the board, or choose New puzzle for another board.
Controls
Tap or click a cell and use the number pad. Keyboard: arrows select cells; digits (and A–G on 16×16) enter values; Backspace erases. On a smaller screen, keep the active part of the board within view. Contact us with the game and device if a control does not respond.
A useful example
On one puzzle in this collection, row 1, column 1 has 6 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Compare this with the rule that governs the move. Keep the controls nearby.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
