Play Classic Sudoku with the rules at hand
Open Classic Sudoku, check the instructions and begin a round. 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. Compare the starting position with the example in the Guide. Look at what changes after your first action.
Try a more deliberate round
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.
What you need to achieve
Fill all cells with 1–9; do not repeat a symbol in any row, column or region. The feedback beside the game helps you follow the round. Start with a deliberate move.
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.
The controls to know
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. Keep the playing area visible while using these controls. A new-round button replaces the current round.
Put the rules into context
On one puzzle in this collection, row 1, column 3 has 9 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
One detail worth checking
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Read the feedback to see why an action did not have the expected result. 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.
