How to play 6x6 Sudoku

Read the aim of 6x6 Sudoku, then make your first move. 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. Begin with the solo mode shown on the page. Use the example below to understand a decision.

Build a steady rhythm

Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the 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. Use the instructions to see which actions move you towards it. Return to the instructions when a step is unclear.

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. A careful first action helps you become familiar with the layout. Look at the feedback after the action.

A useful example

On one puzzle in this collection, row 1, column 2 has 4 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Focus on why the action is allowed, not only its outcome. 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. Check the rule before repeating the action. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
