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. Use the example below to understand a decision. Treat the first round as a chance to learn the controls. Look at what changes after your first action.

A useful comparison

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

Your goal

Fill all cells with 1–6; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Check the rules when you are unsure.

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. On a smaller screen, keep the active part of the board within view. 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 5 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Compare this with the rule that governs the move. Notice the change in the playing area.

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