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. Choose a clear next step rather than rushing through the instructions. Read the objective before making your first input. Use the example below to understand a decision.

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. Use the instructions to see which actions move you towards it. Take a moment to understand the current position.

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 careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.

A useful example

On one puzzle in this collection, row 1, column 4 has 5 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Apply the same reasoning to the position in your own round. 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. 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.
