Rules, controls and help for 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. Look at what changes after your first action. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.

Practice with a purpose

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

What you need to achieve

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. Check the rules when you are unsure.

Follow these playing steps

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.

Your inputs

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. A new-round button replaces the current round.

Follow the example

On one puzzle in this collection, row 1, column 1 has 3 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Your next round may have a different position, so inspect it before acting. Choose a deliberate next step.

A mistake to avoid

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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
