THE PLAYBOOK · QCYANGCHU
The Classic Sudoku playbook
Read the aim of Classic Sudoku, then make your first move. Fill all cells with 1–9; do not repeat a symbol in any row, column or region. Choose a clear next step rather than rushing through the instructions. Compare the starting position with the example in the Guide. Keep the game area visible while you use its controls.
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. Use the example to check your reasoning.
What you are aiming for
Fill all cells with 1–9; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Keep the controls in easy reach.
Work through the instructions
- 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.
How to use the 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. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
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. Use the example as a guide rather than a substitute for reading your board. Look for the relevant detail.
A useful caution
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
