The essentials of playing Classic Sudoku
Make Classic Sudoku your next activity in the game library. 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. Treat the first round as a chance to learn the controls. Choose a clear next step rather than rushing through the instructions.
Try a more deliberate round
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Refer to the controls when needed.
The goal to keep in mind
Fill all cells with 1–9; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Return to the instructions when a step is unclear.
The order of play
- 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.
Your inputs
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. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
See how the rules apply
On one puzzle in this collection, row 1, column 1 has 9 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
Notice this detail
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. 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.
