How to play 6x6 Sudoku

Open 6x6 Sudoku, check the instructions and begin a round. Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Look at what changes after your first action. Compare the starting position with the example in the Guide. Use the example below to understand a decision.

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. Notice how the game responds to your input.

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. Read a button’s label before selecting it. Use the visible help when you are unsure of the next input.

A useful example

Before filling a cell, compare the symbols already used in its row, column and 2 × 3 region. A candidate must be absent from all three. Apply the same reasoning to the position in your own round. 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. Compare the situation with the worked example. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
