Classic Sudoku: from controls to your first round
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. Look at what changes after your first action. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
A small practice goal
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Keep the objective visible.
Understand the aim
Fill all cells with 1–9; do not repeat a symbol in any row, column or region. Use the instructions to see which actions move you towards it. 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.
Using the playing area
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. Make sure you are interacting with the game rather than the surrounding page.
Learn from a sample situation
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. Compare this with the rule that governs the move. Notice the change in the playing area.
A common point of confusion
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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
