Classic Sudoku: what to know before playing
Bring your attention to one round of Classic Sudoku. 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. Read the objective before making your first input. Look at what changes after your first action.
Bring this focus to a round
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.
What counts as success
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. Take a moment to understand the current position.
Start here and follow along
- 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 your actions work
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. Read the example below alongside these instructions.
Follow the example
On one puzzle in this collection, row 1, column 3 has 2 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Apply the same reasoning to the position in your own round. Check the stated objective.
Keep this in mind
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. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
