6x6 Sudoku: instructions and practice

Give this approach a try

When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Keep the objective visible.

Your objective

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. 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.

Input guidance

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. A new-round button replaces the current round.

A useful example

On one puzzle in this collection, row 1, column 1 has 1 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. Read the matching step again.

Avoid this misunderstanding

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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
