A practical guide to 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. Use the example below to understand a decision. Make your first input carefully and watch the result. Look at what changes after your first action.
One thing to notice as you play
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.
What you need to achieve
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. Start with a deliberate move.
Follow these playing steps
- Select an empty cell. The original clues cannot be edited.
- Choose a symbol from the number pad, or type it on a keyboard.
- Turn Notes on to record candidate symbols without committing an answer.
- Use Check entries to check your filled values. Hint reveals one value from the verified solution.
- Complete the board, or choose New puzzle for another board.
Using the playing area
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. Look at the feedback after the action.
One way to understand the rules
Before filling a cell, compare the symbols already used in its row, column and 4 × 4 region. A candidate must be absent from all three. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
