How to play 6x6 Sudoku
Choose a round of 6x6 Sudoku and settle into its rules. Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Keep the game area visible while you use its controls. Make your first input carefully and watch the result. Look at what changes after your first action.
Focus on one rule
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.
Your goal
Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Try to explain the aim in your own words.
Step by step
- 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.
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. Read a button’s label before selecting it. Contact us with the game and device if a control does not respond.
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
