How to play 16x16 Sudoku

Start 16x16 Sudoku by looking at the playing area and its controls. 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. Check the relevant rule before repeating a move.

A careful first round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.

Your goal

Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Review the board or playing area as it changes.

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. Contact us with the game and device if a control does not respond.

A useful example

On one puzzle in this collection, row 1, column 4 has 9 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Your next round may have a different position, so inspect it before acting. Consider the next action carefully.

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. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
