Classic Sudoku: from controls to your first round
Start Classic Sudoku by looking at the playing area and its controls. 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. Treat the first round as a chance to learn the controls. Check the relevant rule before repeating a move.
Try a more deliberate round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Notice the feedback after each input.
The challenge in front of you
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 playing sequence
- 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.
Input guidance
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. Use the control method described here for this activity. Look at the feedback after the action.
Work through an example
On one puzzle in this collection, row 1, column 2 has 9 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. Verify the rule before continuing.
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. 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.
