Find your footing in 16x16 Sudoku

Read the aim of 16x16 Sudoku, then make your first move. Fill all cells with 1–9 and A–G; 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. Choose a clear next step rather than rushing through the instructions.

A focus for your next round

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Notice the feedback after each input.

Understand the aim

Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Read that aim before choosing your first action. Return to the instructions when a step is unclear.

Making your moves

  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.

The controls to know

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. Make sure you are interacting with the game rather than the surrounding page.

Work through an example

On one puzzle in this collection, row 1, column 3 has C 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.

A useful caution

Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
