How to play 6x6 Sudoku

Play 6x6 Sudoku on XH0411, then compare your approach with the example below. Fill all cells with 1–6; do not repeat a symbol in any row, column or region. The accompanying practice note focuses on a short learning break.

A short learning break

Choose one objective for this visit: understand the controls, complete a round, or recognise a common mistake. Progress does not need to be rushed.

Your goal

Fill all cells with 1–6; do not repeat a symbol in any row, column or region.

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 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.

Watch out for this

Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule.
