How to play 6x6 Sudoku

Bring your attention to one round of 6x6 Sudoku. Fill all cells with 1–6; 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.

Review a difficult moment

When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Make the next step deliberately.

Your goal

Fill all cells with 1–6; do not repeat a symbol in any row, column or region. The feedback beside the game helps you follow the round. Try to explain the aim in your own words.

Step by step

1. Select an empty cell. The original clues cannot be edited.
2. Choose a symbol from the number pad, or type it on a keyboard.
3. Turn Notes on to record candidate symbols without committing an answer.
4. Use Check entries to check your filled values. Hint reveals one value from the verified solution.
5. Complete the board, or choose New puzzle for another board.

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. Keep the playing area visible while using these controls. A new-round button replaces the current round.

A useful example

On one puzzle in this collection, row 1, column 1 has 1 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. Keep the game’s format in mind.

Watch out for this

Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
