How to play 6x6 Sudoku

Start 6x6 Sudoku by looking at the playing area and its controls. 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. 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. Refer to the controls when needed.

Your goal

Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.

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. Avoid pressing the same control repeatedly while a move is being processed.

A useful example

On one puzzle in this collection, row 1, column 1 has 6 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. Choose a deliberate next step.

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.
